Get Started Use the fllwing checklist t get started with SQL virtual database. Lcate the backup files fr the database yu want t attach. Get Started Checklist Steps Decide whether yu want t attach a full backup file r attach multiple data files such as transactin lg backups. Create the virtual database accrding t yur specific recvery needs. Use the Query tl t verify yur virtual database was attached crrectly. Use SQL Server Management Studi r anther database management tl t view, cmpare, recver, and reprt n bjects and data frm yur virtual databases. Decide whether yu want t update yur existing SQL Server backup jbs t create file maps autmatically after the regularly scheduled backup peratin is cmpleted. This imprves the virtual database perfrmance, allwing yu t mre quickly access future backups. Mnitr the amunt f disk space used by yur virtual databases.typically, virtual databases require a fractin f the disk space cnsumed by a fully restred backup. If yu are virtualizing large databases, yu may need t allcate additinal disk space ver time.
Upgrade t this build Yu can easily and quickly upgrade t the latest versin f SQL virtual database. Upgrading will nt delete r alter any existing virtual databases hsted by the SQL Server instance n the installatin cmputer. Fr mre infrmatin abut this release, see what s new. T upgrade: 1. Use an administratr accunt t lg nt the target cmputer. 2. Start SQL tlbx. 3. Click the Updates tab. 4. Select SQL virtual database, and then click install. SQL tlbx silently installs the latest versin. 5. Start the SQLvdb Cnsle. Yu can access yur existing virtual databases r create new nes.
What is SQL virtual database? Idera SQL virtual database (SQLvdb) is a pwerful ne-f-a-kind slutin that lets yu attach SQL Server backup files and query them like real databases. With its revlutinary, patent-pending technlgy, yu gain instant access t critical data in a backup file withut spending the time and strage previusly required fr restre. In minutes, yu can create a virtual database and then use any native SQL Server r third party tls t query and extract the data yu need. Features Virtual recvery Prvides instant, feature-rich access t all data frm within SQLsafe backup and native SQL Server backup files. Pint-in-time selectin Prvides pint-in-time selectin and recvery, allwing granular cntrl ver the state f the data displayed in the virtual database. Native SQL Server and third-party applicatin access Use existing SQL Server tls such as SQL Server Management Studi and third-party applicatins t interact with the new virtual database as thugh it were an actual physical database. Intuitive Cnsle Allws virtual databases t be quickly and easily created, edited, r remved. N impact t prductin servers Installs t a single nn-critical server and attaches all virtual databases t a single SQL Server instance.
Hw des SQL virtual database help me? Database administratrs are ften asked t recver a backup in rder t recver bjects and data, cmpare tw systems, r run a reprt. Previusly, the nly way t d this is t restre the database, a cnsuming activity that requires time and strage. SQL virtual database lets yu create a virtual database that appears t SQL Server and third-party applicatins as a physical database. This virtual database prvides direct access t the data withut a restre. This direct access greatly reduces the time required fr data recvery,increases yur prductivity, and reduces resurce requirements. With SQL virtual database, yu can: Eliminate lng restre times Access a backup file and retrieve the bjects r data yu need immediately Save massive amunts f strage Execute any query Use backups fr reprting, data extractin, data analysis, and mre Take the lad ff yur prductin servers and experience zer impact n prductin databases Access full, differential, and transactin lg backup files made by Idera SQLsafe and SQL Server
Hw des SQL virtual database wrk? SQL virtual database is driven by a unique, patent-pending recvery technlgy that makes backup files behave like regular physical databases. This technlgy allws yu t create virtual databases by directly attaching backup files t SQL Server withut requiring a restre peratin. Each virtual database is hsted by the SQL Server instance yu specify. All bjects and data in the virtual databases are accessible t SQL Server jbs and stred prcedures, T-SQL scripts, and ther third-party applicatins. The SQLvdb Engine, which cnsists f a driver and a service, manages the virtual database and services the SQL Server I/O requests t the virtual data files. As the SQLvdb Engine attaches yur selected backup files and creates the virtual database, it cnslidates all the transactins and presents them t SQL Server fr recvery. During this prcess, SQL virtual database "maps" the data frm the backup files. If the data has already been "mapped", such as thrugh SQLsafe r the Map Generatin utility, then SQL virtual database prceeds t the virtual database creatin.yu can create a virtual database by attaching specific data sets frm multiple full, differential, and transactin lg backups. Yu can then use the SQLvdb Cnsle, r any ther third-party tl, t perfrm queries against specific virtual databases r simply check the status f yur virtual databases. Fr mre infrmatin, see ur instructins n hw t use yur virtual database, as well as tips and tricks. The prduct features, such as the virtual database creatin, are als available thrugh the SQLvdb CLI. Fr mre infrmatin, see the prduct cmpnent descriptins. Hw des SQL virtual database wrk with SQLsafe? SQL virtual database seamlessly cnverts SQLsafe backup files int virtual databases. Yu can use SQL virtual database with any backup file generated by SQLsafe 5.0 r later. Fr mre infrmatin, see the prduct requirements. When yu attach a backup file previusly created by SQLsafe 5.0, the SQLvdb Engine perfrms the same steps as it des with the native SQL Server backup. T ptimize perfrmance fr large databases, use the Map Generatin utility t generate the required metadata befre attaching the backup files. With SQLsafe 6.0 r later, yu can cnfigure yur backup peratin t autmatically generate the metadata. By default, this ptin is enabled when yu perfrm a new manual backup r define a new backup plicy. Fr mre infrmatin, see the SQLsafe nline Help. What virtual data files are created? Fr each virtual database yu create, several files are als created t supprt the new virtual database. These virtual data files are: File Descriptin Lcatin Can yu mve it? When is it deleted? *.xbm *.xcm *.xdm *.xtm Files that the SQvdb Driver creates t map the data in the selected backup files. In the same flder where yu stre yur backup files. N... Mving these files will cause errrs when yu attempt t access the virtual database. Never...

Cnfigure yur deplyment After initially installing and setting up SQLvdb, there are several tasks yu might want t d in rder t further custmize and streamline yur deplyment. Change the prt that SQLvdb Service uses Change where the SQLvdb Engine stres cached files during the virtual database creatin Cllect SQLvdb lgs fr trubleshting Grm unused virtual data files Increase perfrmance by preparing backup files fr future data retrieval Manage yur prduct license Select a different drive n which the SQLvdb Driver shuld run
Attach the SQLvdb Driver t a different drive Use the Advanced tab f the Cnfigure windw t attach the SQLvdb Driver t a different drive (vlume). By default, the SQLvdb Driver is attached t a fixed drive n the lcal cmputer, such as the C:\vlume. Cnsider re-attaching the SQLvdb Driver t a vlume that is used infrequently by ther applicatins. Fr mre infrmatin abut ther cnfiguratin tasks, see Cnfigure Yur Deplyment.
Change the prt that SQLvdb Service uses Use the Advanced tab f the Cnfigure windw t chse a different prt. The SQLvdb Service accunt uses the specified prt t cnnect t remte SQL Server instances and netwrk shares. By default, the SQLvdb Service uses prt 5303. Due t netwrk firewall settings and applicatin security plicies, this prt may nt be unavailable r yu may experience a cnnectin issue. If yu encunter cnnectin issues, cntact yur netwrk administratr t verify whether the specified prt is pen. Fr mre infrmatin abut ther cnfiguratin tasks, see Cnfigure Yur Deplyment.
Cllect lgs fr trubleshting Use the System Diagnstics windw t cllect verbse lgs that can be used fr trubleshting by Idera Supprt. By default, highlevel lgging is always enabled fr SQL virtual database activities and events. TIP If yu are encuntering cnnectin issues, cntact yur netwrk administratr t verify whether the prt cnfigured fr the SQLvdb Service is pen and available. Hw d I access system diagnstics? 1. On the SQL virtual database Welcme windw, click Help & Mre. 2. Click System Diagnstics. Hw d I cllect the lgs? 1. Click Cllect. SQLvdb creates a zipped flder f the specified lg files and places this flder n the Windws desktp. By default, the zip flder is named IderaSQLvdbCllectinLgInstanceNameTimeStamp.zip. 2. Email the zipped lg flder t Idera Supprt. Hw d I cllect lgs fr issues encuntered when installing SQL virtual database? 1. Start the Windws Cmmand Prmpt. 2. Navigate t the installer directry (by default, C:\Dcuments and Settings\User Name\My Dcuments). 3. Type ne f the fllwing cmmands: Server Type Installatin Cmmand x86 (32-bit) x64 (64-bit) msiexec /i SQLvdb.msi /l*v C:\MyFlder\SQLvdb_install.lg msiexec /i SQLvdb-X64.msi /l*v C:\MyFlder\SQLvdb_install.lg 4.

Fr mre infrmatin abut ther cnfiguratin tasks, see Cnfigure Yur Deplyment.
Manage yur license keys Use the Manage SQLvdb License ptin t view details abut yur trial r prductin license and perfrm actins such as activating a license. Frm the licensing cnsle, yu can: Verify current status f yur license Extend yur trial perid Register and activate yur license Deactivate yur license Fr mre infrmatin abut ther cnfiguratin tasks, see Cnfigure Yur Deplyment. Fr mre infrmatin abut the licensing cnsle, see the licensing nline Help. Hw d I access the licensing cnsle? 1. On the main SQLvdb Cnsle windw, click Help & Mre. 2. On the Help windw, click Manage SQLvdb License. This ptin pens the licensing cnsle. What is the trial license? By default, SQL virtual database installs with a limited-time trial license key that is valid fr the cmputer n which yu have installed the tl. When yu decide t mve frm a trial implementatin f SQL virtual database t yur prductin envirnment, cntact and btain a license key frm Idera. Hw des SQLvdb licensing wrk? SQL virtual database checks fr a valid license each time yu start the tl. A valid license is a trial r prductin key that has been registered fr the cmputer n which yu have installed the SQL virtual database tl. If yur license expires, such as when the trial perid ends, the Cnsle functinality will be limited t remving previusly created virtual databases and managing yur prduct license. Yu can cntinue t access existing virtual databases using tls such as SQL Server Management Studi. If yur license is deactivated, yu will n lnger be able t use the tl. Yu can re-install the tl and reuse a previusly deactivated prductin key.
Prepare backup files fr future data retrieval Use the Map Generatin utility t prepare yur backups fr future data retrieval. Yu can use this utility t autmatically generate virtual data files fr specific backups n a rutine basis. Fr example, yu can schedule a SQL Server jb that searches fr new backup files and then generates the crrespnding virtual data. By building the virtual data befre attempting t attach the backup file, yu can decrease the time required t create the virtual database and get faster access t yur data and bjects. The larger the database is, the mre time yu can save by preparing yur backups. Cnsider running this utility n backups fr missin-critical and sensitive databases, as well as databases that ften require bject recvery and data retrieval. Hw d I deply the utility?

Tips and Tricks Idera prvides several tips and tricks s yu can get the mst value frm SQL virtual database. Yu can watch a vide demnstratin r read custmer testimnials n the Idera Web site (http://www.idera.cm/prducts/sql-tlbx/sql-virtual-database/). The fllwing tasks are a small sample f the many ways yu can use yur virtual database: Create DDL scripts fr entire databases, tables, r rws Identify rws that were added, mdified, r deleted since yur last backup Recver stred prcedures Recver tables using bulk cpy Reprt n data changes using T-SQL queries Run histrical reprts using Micrsft Reprting Services View user, rle, r schema changes All f these tasks can nw be dne withut restring the database!
Create Virtual Database Create virtual databases t access, cmpare, recver, and reprt n data frm previus backups f databases in yur envirnment. Fr example, yu can create multiple virtual databases, at different pints in time, frm backups f the same live database. This strategy allws yu t cmpare clumn values and schema bjects frm ne versin f the database t anther versin several days later withut restring the database. Yu can create a virtual database by either: Attaching a single full backup file Attaching multiple backup files, including transactin lg backups Virtual databases can be created thrugh the SQLvdb Cnsle r CLI. What is a virtual database? A virtual database (vdb) is a patent-pending sftware implementatin f a database that allws fr data strage and retrieval like a physical database. Because a virtual database acts like a physical database, yu can access any data r bject in the virtual database using T-SQL scripts, third-party applicatins, reprting tls, and database management tls such as Micrsft SQL Server Management Studi. Database management tls interface with and display the virtual database as a physical database. Each SQL Server instance can hst multiple virtual databases. What can I d with a virtual database? Any peratin that yu can perfrm n a physical database can be perfrmed n a virtual database. Likewise, applicatins that rely n getting infrmatin frm this database can cntinue using the virtual versin. Yu can use the built-in query tl t execute cmmands n bjects in this virtual database. Yu can als access this virtual database using Micrsft SQL Server tls, such as Management Studi, and ther third-party applicatins. Fr mre infrmatin, see ur tip and tricks. TIP Yu can mdify the data and bjects in the virtual database. Hwever, because the virtual database is based n archived data, yur changes will nt persist when yu recreate the same virtual database later. T preserve yur changes, back up the mdified virtual database and then create a new virtual database using thse backup files. Hw d I access the CLI? T access the SQLvdb CLI, start the Windws Cmmand Prmpt, and then enter sqlvdbcli t see which cmmands and ptins yu can use. Fr mre infrmatin abut the SQL virtual database cmpnents, see the prduct cmpnents.
Attach a single backup file Use the Attach Full Backup windw t easily create a virtual database frm a single full backup file. Fr mre infrmatin abut hw yu can use the virtual database, see ur tips and tricks. TIP When yu select a backup file, SQL virtual database pens the file in shared read mde. When Micrsft SQL Server r Idera SQLsafe attempts t append (write data t) r delete this file, the backup peratin will fail because the file is lcked fr read. If yur backup plicies r jbs are cnfigured t append new data sets t this file, change yur backup settings s that a new and unique file is created fr each backup. Which backup files can I use? Yu can select any full backup files created by Micrsft SQL Server r Idera SQLsafe. Fr mre infrmatin, check the supprted backup file frmats. Fields Backup File Type r brwse t the directry path and filename f the backup file yu want t use. Yu can specify a single file fr any full backup perfrmed n the target database. Backup files can be lcated n the lcal cmputer r a netwrk share. T specify a netwrk path, use UNC snytax (\\MyServer\MyFlder\MyBackup.bak). Hst Instance Type the name f the SQL Server instance that shuld hst the virtual database. Yu can brwse fr instances running n the lcal cmputer. Virtual Database Name Type a unique name yu want t use fr yur new virtual database. This name will be displayed in the Cnsle and in ther database management tls, such as Micrsft SQL Server Management Studi.
Attach multiple backup files The Attach Multiple Backups wizard lets yu build a live virtual database based n data frm specific backup files. With this wizard, yu will: Select the backup files yu want t include Select the date and time up t which yu want data Specify hw yu want the virtual database t display in the Cnsle and ther tls Fr mre infrmatin abut hw yu can use the virtual database, see ur tips and tricks.
Select the backup files Use the Backup Files tab t select which backup files yu want t use t create yur virtual database. TIP When yu select a backup file, SQL virtual database pens the file in shared read mde. When Micrsft SQL Server r Idera SQLsafe attempts t append (write data t) r delete this file, the backup peratin will fail because the file is lcked fr read. If yur backup plicies r jbs are cnfigured t append new data sets t this file, change yur backup settings s that a new and unique file is created fr each backup. Which backup files can I use? Yu can select any full, differential, and transactin lg backup files created by Micrsft SQL Server r Idera SQLsafe. Fr mre infrmatin, check the supprted backup file frmats. Why are ne r mre f the selected backup files displayed in range text? After yu add yur backup files, SQL virtual database checks the LSN (lg sequence number) range f each file t ensure it is in sequence. When the LSN range is ut f sequence, the affected files d nt cntain all f the lgged transactins required t create an accurate virtual database. If an LSN range is ut f sequence, such as a gap between ne file and the next, the affected files are displayed in range text. T reslve this issue, add mre backup files t fill the LSN gap. Als cnsider verifying the backup files t ensure a cmplete backup had been perfrmed. Fr mre infrmatin, see Micrsft SQL Server Bks Online. Actins and Tasks Add a backup file t the list Click Add t select a backup file t use when creating this virtual database. T add a file, first type the path and filename in the prvided field, r brwse fr the files. Yu can als use wildcards t find flders r files that match a naming cnventin. If the selected backup file cntains data fr mre than ne database, yu will be prmpted t chse which data set yu want. If the selected backup file cntains encrypted data, yu will be prmpted t prvide the passwrd required t decrypt the file. If the backup was written (r striped) t multiple files, yu will need t add each file in the stripe. Brwse fr backup files Click the brwse buttn t find the files yu want t use. Cnfigure encryptin settings Select the listed backup files that are encrypted and then click Encryptin Settings t specify the passwrd required t decrypt the data. Remve a backup file frm the list Click Remve t delete a previusly selected backup file frm the list f files t use when creating this virtual database. Clumns and Fields

Database Prvides the name f the database whse data was archived in this backup file. Filename Prvides the name f the backup files yu selected. First LSN Prvides the LSN at which each backup file starts. Fr mre infrmatin abut LSN ranges, see Micrsft SQL Server Bks Online. Instance Prvides the name f the SQL Server instance hsting the archived database. Last LSN Type Prvides the LSN at which each backup file ends. Fr mre infrmatin abut LSN ranges, see Micrsft SQL Server Bks Online. Indicates which type f backup was perfrmed when the selected files were created.
Chse the target pint in time Use the Pint in Time tab t chse the exact date and time at which yu want t create the database. Yu can pick any date and time included in the data sets f the selected backup files. If yu d nt see the pint in time yu want, yu may need t chse different backup files. Fr example, t pick an hurly interval, select transactin lg backup files. Actins and Tasks Pick a date and time Yu can use either the slider r the calendar t pick the exact date and time yu want t recver. After yu select a date and time, SQL virtual database lists which data sets will be used t create the virtual database up t the selected pint in time. Pick an LSN SQL Server 2005 and later allws yu t use a LSN (lg sequence number) t identify the pint at which yu want t recver data. T recver up t a specific LSN range, select LSN frm the drp-dwn menu, and then chse the apprpriate backup file. Verify data sets Use the grid t verify which data sets will be used t create the virtual database up t the selected pint in time. Depending n the pint in time yu selected, SQL virtual database may nt need t use all the data sets available in the backup files. What is a pint in time? A pint in time prvides a histrical perspective f a physical database at the specified date and time. Yu can create multiple virtual databases, representing different pints in time, frm the same set f backup files. Fr example, yu can create three virtual databases that represent the physical database n Mnday, Tuesday, and Wednesday. Yu can then access data and bjects frm the database as it existed n Mnday, Tuesday, r Wednesday. A pint in time can help yu: Analyze different versins f the same database Cpy different versins f the same bject Cmpare changes in data and schema bjects frm ne time perid t anther Reprt n data that existed at a given date and time Hw d I use the slider? Use the slider t pick a pint in time during any hur f the mst recent day in the selected backup files. As yu hver ver the slider, the available time intervals display. T pick a time, click the crrespnding interval. Hw d I use the Calendar? Use the calendar interface t chse a date and time in any available mnth by selecting the apprpriate area n the displayed day. As yu hver ver a day, the available hur intervals display. T pick a time, click the crrespnding interval. The calendar interface indicates whether data is available fr a given date and time, based n the backup files yu selected. The calendar shws when different types f backups were perfrmed t help yu chse the crrect files s that yu have the data yu need.
Specify hw the Cnsle creates this database Use the Create As tab t specify hw SQLvdb shuld create yur new virtual database. TIP The specified name and descriptin will display in the Cnsle and in ther database management tls, such as Micrsft SQL Server Management Studi. Actins and Tasks Specify the hst instance Type the name f the SQL Server instance that shuld hst the virtual database. Specify the virtual database name Type a unique name fr yur new virtual database. Specify a descriptin Type a descriptin fr this virtual database. Use a descriptin that includes details abut this data set t help yu trublesht issues, administer yur databases, r recver specific bjects.
Review summary f new virtual database cnfiguratin Review the prvided summary, and then click Finish. When yu finish this wizard, SQL virtual recvery will create a virtual database accrding t yur specificatins. After yu cmplete this wizard, the Cnsle will list yur new virtual database in the Welcme windw. Yu can use the built-in query tl t execute cmmands n bjects in this virtual database. Yu can als access this virtual database using Micrsft SQL Server tls, such as Management Studi, and ther third-party applicatins. If yu want t change a setting nw, click Back t return t the apprpriate windw. Yu can als change these settings later using the Edit buttn n the SQLvdb Cnsle Welcme windw.
Edit cnnectin credentials Use the Edit Credentials windw t specify different cnnectin credentials.sql virtual database will use these credentials t cnnect t the target SQL Server instance, read the specified backup files, and create the virtual database. By default, the SQLvdb Service credentials are used. Hwever, the service accunt credentials may nt have the apprpriate privileges n the target SQL Server instance r the directry where the backup files are stred. This issue is mre likely t ccur when backups have been striped acrss multiple files lcated in different netwrk shares. Ensure yu specify a Windws accunt that has the apprpriate permissins, and then click OK. Fr mre infrmatin, check the permissins requirements.
Errr when missing backup files Use the Missing Striped Backups windw t reslve issues caused by missing data files. This windw displays when a backup file yu selected is ne f several files created by a striped backup and yu did nt select all f the files required t create the virtual database. T specify mre backup files, type the path and filename f each file (r use the brwse buttn t navigate t the target file), and then click Add. Fr mre infrmatin abut hw striped backups wrk, see Micrsft SQL Server Bks Online.
Hw t use yur virtual database Yu can access yur virtual database using any third-party tl, such as: SQL admin tlset Multi Query tl SQL cmparisn tlset SQL Server Management Studi Fr mre usage ideas, see ur tips and tricks. Hw t use the Multi Query tl in the Idera SQL admin tlset 1. Click Multi Query frm the SQL admin tlset Launchpad. 2. Add a new query r pen an existing query. Fr mre infrmatin, see the SQL admin tlset nline Help. 3. Execute yur query against the selected targets. In this case, the selected targets shuld include the virtual databases yu want t query. Hw t use SQL Server Management Studi 1. Cnnect t the SQL Server instance that is hsting yur virtual database. 2. In the Object Explrer, expand the Databases nde. 3. Select yur virtual database frm the list. Each virtual database will display as a physical database. 4. Perfrm an actin r run a query. Fr usage ideas, see Tips and Tricks.
Test yur virtual database Yu can test yur new virtual database using Micrsft SQL Server Management Studi (Management Studi) r the built-in Query Database tl. With either applicatin, yu can test yur virtual database by perfrming simple T-SQL queries, such as testing whether yu can select data frm a specific table. When yu click Run Queries n the Welcme windw f the SQLvdb Cnsle, SQL virtual database starts the Management Studi tl. If Management Studi is nt installed n the lcal cmputer, SQL virtual database starts the built-in Query Database tl instead. Hw d I use the Query Database tl? Yu can immediately begin using the Query Database tl by typing r cpying a script in t the editr pane, picking the virtual database n which yu want t run yur script, and then executing the query yu entered. The fllwing actins and tasks are available frm this tl. Chse the target database Use the Target Database(s) field t select which virtual databases shuld be tested with this query. Run the query Click the execute buttn t run yur script. Cntrl hw yur query is run Use the Query tab n the Optins windw t set run prperties, such as the maximum number f returned rws and the executin timeut value. Change hw the editr pane displays yur cde Use the Editr tab n the Optins windw t set the editr pane prperties, such as whether t shw line numbers r highlight syntax errrs.
Edit Virtual Database Settings The Edit Virtual Database Optins wizard lets yu change the cnfiguratin f a virtual database. With this wizard, yu can: Change the data set by specifying different backup files Chse a different date and time Rename the virtual database r edit the descriptin When shuld I edit the virtual database settings? Yu shuld edit yur virtual database cnfiguratin when: Yu need t query r recver bject data frm a different time perid Yu want t change hw the virtual database is displayed in the SQLvdb Cnsle and ther third-party applicatins Hwever, yu may want t cnsider creating a new virtual database t use alng side the existing virtual database.
