7 Traditional Database Backup Best Practices Local Disk Backups On-site Tiered Storage Off-site Storage Local disk backups Short term retention Example: 7 days Quickest RTO Image copy Backup Sets Storage tier based on data value & retention requirements Disk-to-Disk (Ex: 30 days) Disk-to-Tape (Ex: 90 days) Disk-to-Disk-to-Tape (EX: days) Tapes physically shipped to offsite (Tape Vaulting) Long term retention & Archiving (Ex: 5 yrs) Compliance, Regulatory & DR purposes 7

8 Challenges with Backup Infrastructure On-Demand Capacity Growth With explosive data growth, storage capacity planning for the long term retention is a challenge High Cost Incurs capital expenditure to procure, higher operation cost to manage onsite & offsite storage infrastructure No DR/Tape Infrastructure Not everyone has tape infrastructure or remote (DR) site for taking backups and to store offsite Accessibility Issues With Tape-vaulting, offsite data is not immediately accessible which increases RTO Cloud Storage provides a great alternative!!

9 Cloud Infrastructure for Backup & Archive Top Use Cases 9

11 Oracle Database Backup Cloud Service (PaaS) Offsite Backups with Simple and Low Cost Cloud Storage Backup on-premise or cloud databases to Oracle Cloud Cloud Databases Cost effective, scalable cloud storage for database backups (10.2 and above) End-to-end enterprise-grade data encryption, compression and protection Clients: Data is always encrypted with keys kept locally at client, optionally compressed, and securely transmitted Cloud: Encrypted data is protected with 3- way mirroring on every write On-Premises Oracle Database Backup Service Oracle Cloud 11

12 Oracle Database Backup Service Subscription Models Database Backup Database Cloud Non-Metered (Subscription) Fixed $33/TB per Month Standalone (or) combined with DBCS non-metered services Month-to-month or longer Trial : Storage Cloud / 10GB Metered Model Pay-per-use ($/GB) + Transfer & Request charges Included with Metered DBCS Subscription Use with DBaaS / Exadata Cloud or just backup 1 Year or longer term Trial: DBCS / 500GB Subscription includes cloud storage, RMAN Module, RMAN Encryption, RMAN Compression and support 12

13 Database Backup Service: Benefits Offsite Cloud Storage for Oracle Database Backups Platform as a Service Oracle Database Backup Service Instant Offsite Storage Cost Effective On-Premises Databases 10.2 and above Oracle DBaaS and Exadata Cloud Service On-demand Scalability End-to-End Security Encryption Compression 3-Way Protection 24x7 Data Availability 13

14 How it works Oracle Database Backup Service Leverages familiar RMAN interface DB Backup Oracle Database Cloud Backup Module Oracle RMAN Customer data center Perform compressed backup, restore & recovery using RMAN (optional) RMAN encryption for backups is enforced (mandatory) Keys kept locally on client (password, TDE, dual-mode) Data securely transmitted to the cloud over HTTPS To optimize data transfer Use RMAN compression (HIGH, MEDIUM, LOW, BASIC) Increase PARALLELISM (until you reach maximum throughput) Use MULTISECTION backups Use weekly full/daily incremental strategy Oracle Confidential Internal/Restricted/Highly Restricted 14

15 Backup Service: End-to-End Flow Simple 4-Step Process Storage Capacity Identity Domain Service Name User ID/Password Cloud Subscription & Activation Install RMAN Module Download & Execute Installer Library module installed along with config file & wallet Tape Interface Encryption Compression Parallelism Configure RMAN Perform Backup & Recovery RMAN Interface Full & Incremental backups Restore & Recovery Oracle Confidential Internal/Restricted/Highly Restricted 15

16 UI Management for Backup & Recovery Enterprise Manager 13c Oracle Cloud as a backup destination Config, Schedule, B&R Cloudberry Lab Simple UI to perform backup & recovery operations RMAN CLI Perform complex operations via scripting $ rman target / RMAN> CONFIGURE CHANNEL DEVICE TYPE SBT PARMS='SBT_LIBRARY= /opc/libopc.so, SBT_PARMS=(OPC_PFILE=/opc/opcSID.ora) '; RMAN> CONFIGURE DEVICE TYPE SBT PARALLELISM 8; RMAN> SET ENCRYPTION ON IDENTIFIED BY mypwd ONLY; RMAN> BACKUP AS COMPRESSED BACKUPSET DATABASE PLUS ARCHIVELOG; 3 rd Party Application Support In the Roadmap: 16

17 Support Matrix Versions Oracle Database Enterprise Edition* Oracle Database SE/SE1/SE2* Platforms (64 bits) RMAN Compression (Included) RMAN Encryption (Included) , 11.1,11.2, 12c (64 bits) , , , and versions and above Linux, Solaris, SPARC, Windows, HP-UX, AIX, zlinux HIGH, MEDIUM, BASIC, LOW (depends on DB version) Password, TDE, Dual-mode * Older Database versions no longer supported by Oracle are in deprecated mode 17

18 Related Oracle Storage Cloud Services Object Storage Archive Storage Database Backup Software Appliance Bulk Data Transfer Services NFS Storing non- Database Data Super low-cost Long Term Retention Database Backups Gateway with Local Copy One time large data load 18

20 Use Case #1: Backup Directly to Oracle Cloud Requirements Customer has a number of 2 nd & 3 rd tier databases Sizes < 1TB Expensive (CAPEX & OPEX) to allocate and manage local storage for these DB backups Retention : 1-3 years RTO : Hours to Days RPO : As of last backup Solution Directly backup databases + archived logs to Oracle Cloud over public network Weekly full + Daily Incremental strategy Databases Recovery Manager SSL Protect Databases with Offsite Backups Directly back up Oracle Databases c Major platforms Secured, Compressed backup No expensive DB backup agents Oracle Database Backup Cloud Service 20

21 Use Case #2: Backup to Disk and then to Cloud Requirements Customer has a number of mission critical & mission critical databases Wants to maintain offsite storage for long term retention DB Sizes 1-5TB Retention Local disk: 1 month, Cloud: 1-5 years RTO : Days to restore from older backups Solution Do image copy backups to local disk (1), and backup to cloud from the local disk (2,3) Databases Recovery Manager 1 2 Local Disk Backup 3 SSL Oracle Database Backup Cloud Service 21

22 Use Case #3: DR to the Cloud for Database Using Backups Requirements Offsite DR instance using backups Offsite test/dev instance Solution Backup on-premises databases to cloud using Database Backup Service Cloud: Use DBaaS (any edition) or Exadata Cloud Service In the event of outage, restore in the cloud 22

23 Use Case #4: Hybrid Cloud Disaster Recovery (Full Stack DR) Using Backups Requirement: Full DR to the Cloud using backups Database Use Database Backup Service to send on- premise database backups to Oracle Cloud using RMAN Restore the database in the cloud from the backup Application Tier Use JAVA / REST calls to copy on-prem application data to Storage Cloud Service You can also use OSC Appliance for the copy Restore the data into the compute cloud from the object storage 23

24 Backup & Recovery in the Cloud: Oracle DBaaS Oracle Database as a Service (PaaS) RDBMS Oracle Storage Cloud Oracle VM Oracle Linux RMAN Archives Oracle REST Data Services /u03 /u02 /u01 Cloud Utilities & EM Express Oracle Compute Block Storage AA36-8FE4-4D62-9F18-A0550D4BC89B.htm#CSDBI3342 DBaaS Backup Options Block (local) + Object Storage (Cloud Backup) None (No Backups) Automated RMAN backups 7 days on local (FRA) + 30 days on object storage Daily incrementally updated local backup Merge with 7 days delay Daily full backups from FRA to cloud Manual RMAN backups $ /var/opt/oracle/bkup_api/bkup_api bkup_start On-demand full / PIT recovery $ dbaascli orec --args -pitr TAG T Similar B&R for the Exadata Cloud Service 24

25 Target Databases (Backups Using Public Network) Candidates for Cloud Backup Database sizes in GBs to low single digit TB Relaxed Recovery Time objective Direct from database or from disk backups for critical databass Additional copy of backup data in the cloud Not Suitable for Cloud Backups Very large databases with many TBs of data* Strict downtime requirements Predictable recovery time requirement* Mission critical databases with cloud backups the only backup Cloud Backup Tier Level Database Type 1 st 2 nd 3 rd Non-Critical Important Mission Critical * Could become suitable if Oracle Fast Connect is chosen 25

26 Additional Use Cases for Database Backups in Oracle Cloud Database Migration to Oracle Cloud Create a DR instance in the Oracle cloud with periodic updates from backups Create test & dev in the Oracle Cloud Create a Data Guard Standby instance in the Oracle cloud 26
