4 Automated Database Backup Procedure to create an automated database backup 1. General Information The Omnicast Directory service relies on the Directory database to store the system settings. In order to backup your system configuration (video parameters, video units, camera names, user privileges, alarm entities, recording parameters, connection types, etc.) you only need to backup the Directory database to a safe location. If ever a server failure or a database corruption should occur, restoring that database will be necessary to retrieve the previous system configuration. This document explains how to create an automated database backup according to a schedule. The next sections describe the steps for the Directory database but they could also be applied to the other Omnicast databases (alarms, video archives, metadata) Document Revision Date Description Document creation Updating document with the new format 1.2. Contacting Technical Assistance Customers can reach Genetec s Technical Assistance Center (GTAC) using any one of the following methods: Log in to Genetec s Technical Assistance Portal (GTAP) Send questions, via e mail, to: support@genetec.com Telephone questions to the GTAC at: or (Canada and US only) FAX questions to the GTAC at: From Monday to Friday, 8:00 AM to 8:00 PM (Eastern time, GMT 5h) No matter which method is used to reach the GTAC, customers should be ready to provide all relevant information describing the problem or question, including System ID and version information. 4

5 2. Backing up the Database 2.1. Creating the Database Backup Script For further SQL Server Express management options, it is necessary to download and install SQL Server Management Studio Express. The installation file can also be found at: ca/express/bb aspx This is a free tool from Microsoft that will be used to create a script to backup the Omnicast database. 1. Once the tool is installed, launch Microsoft SQL Server Management Studio Express and connect to the OMNICAST instance. The server name is usually <server name>\<instance name>. In the screenshot below, the server name is ipicot and the instance name is Omnicast. 2. Once connected, expand Databases and you will see the Omnicast databases. 5

6 3. Right click the database you want to backup and select Tasks / Backup. 4. A dialog box appears allowing you to define different options such as what type of backup (full or differential) you want to do, backup destination, etc. Please note the difference between the Backup set name which is the name for the backup job and the Backup file name which can be specified when clicking the Add button. That file will be physically located on your hard drive. 6

7 5. Configure the available options as desired then click the Options page on the left hand column. Continue configuring options accordingly. For example, you may want to select overwrite all existing backup sets. 6. At this point, if you only want to perform a manual backup (one time), just click the OK button. The Progress panel will indicate the progression. 7. If you want to schedule an automated backup (scheduled), once all desired options are set, select Script / Actions to File and enter a desired file name for the script, for example, DirectorySQLBackup, and specify the location where to save the file. 7

8 This creates a.sql file which scripts the options you defined in the prior step. The contents of your.sql file may look like this: BACKUP DATABASE [DirectorySQL] TO DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL$OMNICAST\Backup\DirectorySQL.bak' WITH NOFORMAT, NOINIT, NAME = N'DirectorySQL Full Database Backup', SKIP, NOREWIND, NOUNLOAD, STATS = 10 GO To test your.sql file, run the following from a command prompt: sqlcmd S <enter server name>\omnicast i "C:\<enter path to.sql file>\directorysqlbackup.sql" After running the SQL script, the DirectorySQL.bak file will be created with the correct data and time stamp. By default the DirectorySQL.bak is located in C:\Program Files\Microsoft SQL Server\MSSQL$OMNICAST\Backup. (This folder might be MSSQL.1 or MSSQL.x depending on what else is on your server.) 2.2. Automating the Database Backup You can automate the backup process by creating a SQLCMD scheduled task as follows: 1. First, create a Scheduled Task to automate the.sql script created above. Use the Scheduled Task Wizard (Start / All Programs / Accessories / System Tools / Scheduled Tasks). 2. When asked to select a program, browse to C:\Program Files\Microsoft SQL Server\90\Tools\binn\SQLCMD.exe. 3. Define the Schedule Task parameters accordingly and click Finish. 4. Go the properties of the newly created Scheduled Task and edit the Run command as such: 8

9 "C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLCMD.EXE" S <enter server name>\omnicast i "C:\<enter path to.sql file>\directorysqlbackup.sql" 2.3. Copy to a Network Share Location If desired, create a simple batch file to copy the DirectorySQL.bak from the local server to a network share located on server being backed up regularly. For example, create a text file named CopyDirectorySQL.cmd with the following contents: copy "C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\DirectorySQL.bak" "\\<servername>\<sharename>\" Lastly, create a simple Command Prompt Scheduled Task and configure accordingly. Make sure to run this Scheduled Task after the SQLCMD Scheduled Task. Go to the properties of the newly created Scheduled Task and edit the Run command to point to the location of CopyDirectorySQL.cmd file (or your respective batch file name). 9

10 3. Restoring the database Should a failure to occur, you might need to restore the Directory Database from the backup set you created. You can easily restore the database by using the following procedure: 1. The first step for restoring the database is to stop the Omnicast Directory service. You can do it from the Server Admin by clicking the Stop button. We also recommend stopping the Gateway and the Directory Failover Coordinator services. If ever the services are restarted by the WatchDog, simply stop them again. 2. Launch Microsoft SQL Server Management Studio Express and connect to the OMNICAST instance. 3. Right click the database you want to restore and select Tasks / Restore / Database. 10

11 4. Normally, the source for restoring can be left to From database. Make sure to have the right backup set selected: 5. Alternately, you can also choose to restore From device and manually browse to a backup set file. In that case, you will have to specify the backup location by clicking the Add button: 11

12 6. Once you click OK to select the file, the Backup set content will be displayed. Choose the backup date you want to restore: 7. Once the correct restore source has been chosen, click OK to start the restore operation. The Progress panel will indicate the progression: The database has now been restored. Start the Omnicast services and verify your settings by logging to the Config Tool. 12
