Concurrent streams Specify the number of concurrent data streams for backup The maximum (default) value is the number of selected backup devices, for SQL Server supports only one data stream per device.

Fast direct mode Select this option for critical production SQL Servers that require fast backup with minimum impact on their performance. This option can only be used with locally connected devices and the same block size.

Check database integrity Select this option to verify the SQL Server data integrity before backup. If the check fails, backup completes with warnings.

SQL backup compression Specify how Data Protector should handle the Microsoft SQL Server backup compression.

Exclude from backup Specify this option to exclude specific databases from backupPre-exec, Post-exec Specify a command with arguments or a script (filename) that will be

executed on the SQL Server system after backup.


Creating the SQL backup specificationScheduling the Backup

– Schedule the backup.

– For Backup types see table on next slide.


Creating the SQL backup specificationSQL Server online backup types

Backup type Description

Full database backup Includes all data regardless of the changes made after the last backup.

Transaction log backup Uses fewer resources than database backups, so can be created more frequently. By applying transaction log backups, you can recover the database to a specific point in time.

Differential database backup Records only changes made to the database since the last full database backup.

Copy-only database backup A copy-only full backup is an independent full backup, which never truncates the transaction logs and does not affect an SQL Server restore chain.


Creating the SQL backup specificationSaving the Backup

– Save the backup specification, specifying a name and backup specification group.

– Use „speaking“ names for thebackup specifications.


Running the backup


SQL Backup – Summary

– The backup was done using the default settings

– Default setting for the „Load Balancing and Min/Max“ option - „1/5“

– Concurrent streams defaults to 1 1 stream used to back up the data to StoreOnce

– Overall speed might be too slow for larger databases

– Device Locking: Depending on DP version and used device - five devices might be locked, even if onlyone stream was used for the backup (see omnidbutil -show_locked_devs)


Optimization

– Omnirc – recommended settings:– OB2IPCKEEPALIVE = 1

– OB2IPCKEEPALIVETIME = 900

– OB2IPCKEEPALIVEINTERVAL = 60

Disable recovery catalog auto backup

By default, Data Protector backs up the recovery catalog in every backup session.

Disable Data Protector managed control file backup

By default, Data Protector backs up the Data Protector managed control file in every backup session.

Back up standby database Oracle Data Guard: This option is applicable if the database is configured with the standby connection. By default, RMAN backs up the database files and archived redo logs on the primary system. Select to enable backup of database files and archive logs on standby system.

RMAN Script You can edit the Oracle RMAN script section of the Data Protector Oracle backup specification.

Pre-exec, Post-exec Specify a command or RMAN script that will be started by ob2rman.pl on the Oracle Server system before the backup (pre-exec) or after it (post-exec). RMAN scripts must have the .rman extension.


Creating the Oracle backup specificationScheduling the Backup

– Schedule the backup.


Creating the Oracle backup specificationScheduling the Backup

– With Oracle full and incremental level 0 backups all data blocks per datafile are backed up. With Oracle incremental backup (level 1 or higher), only the data blocks that have changed since a previous backup are backed up.

– The difference between a full backup and an incremental level 0 backup is that the incremental 0 is a base for subsequent incremental backups.

– Oracle incremental backups can be differential or cumulative. By default, Data Protector performs Oracle differential incremental backups.


Creating the Oracle backup specificationSaving the Backup

– Save the backup specification, specifying a name and backup specification group.

– Use „speaking“ names for thebackup specifications.


Running the backup


Oracle Backup – Summary

– The backup was done using the default settings.

– Because of the default settings the „Load Balancing and Min/Max“ option „1/5“ was used. As a result 5 streams were used to backup the database.

– The overall speed for the backup might be too slow for larger databases.

– The backup specification is not optimized to back up the data to StoreOnce


Optimization

– Omnirc – recommended settings:– OB2IPCKEEPALIVE = 1

– OB2IPCKEEPALIVETIME = 900

– OB2IPCKEEPALIVEINTERVAL = 60

– Omnirc – optional settings (may change the behavior during backup)– OB2_DPMCTL_SHRLOC

– ORA_ASM_HOME

– ORA_ASM_LCL_INSTANCE

– OB2CATPATH

– OB2_ORACLE_RC_USER

– OB2_ORACLE_ASM_OSUSER

– Zero Downtime Backup: ZDB_ORA_INCLUDE_CF_OLF, ZDB_ORA_INCLUDE_SPF, ZDB_ORA_NO_CHECKCONF_IR, ZDB_PRESERVE_MOUNTPOINTS, ZDB_MOUNT_PATH, ...


Optimization

– Compression / Encryption– Disable Oracle compression / encryption / optimization to achieve better dedupe ratio

– RMAN> CONFIGURE BACKUP OPTIMIZATION OFF;– RMAN> CONFIGURE ENCRYPTION FOR DATABASE OFF;

– Concurrency / Streams / Channels– Increase devices / streams / channels to back up with higher performance

– Better deduplication (next slide):– filesperset 1– maxopenfiles 1


Example Oracle Script – backup database


Example Oracle Script – backup archive (1)

– Post-exec– POSTEXEC "Archive2_ORACLEDB_DB1.cmd" -on_host "cell.server"

Example Oracle Script – backup archive (2)


OptimizationCompare the performance

Backup Job – default settings– 5 stream

Backup Job – optimized settings– 15 streams


Other Recommendations

– Incremental Backups: when planning for incrmental backups and to reduce backup time for large databases consider to enable Oracle „Change Block Tracking“.

– Use the Oracle recovery catalog as central repository for your databases.

– Other usefull commands – can help to reclaim space on StoreOnce (Houesekeeping):– To clean obsolete backups run the commands (RMAN script):

– list backup summary;

– DELETE NOPROMPT OBSOLETE;– DELETE NOPROMPT EXPIRED BACKUP;– DELETE NOPROMPT EXPIRED COPY;

– To synchronize recovery catalog and StoreOnce media (RMAN script):– CROSSCHECK BACKUPSET;– CROSSCHECK COPY;

– „Archive Save“ + „Archive Second Copy and Delete“


Best Practice for Oracle Backup and Recovery

– Database in ARCHIVELOG mode for online backup and point in time recovery

– RMAN parameter FILESPERSET 1 will improve deduplication ratio

– Use Block Change Tracking for incrementals backups (configure in Oracle)

– Backup policy:– Weekly full and daily incremental to reduce compute, bandwidth and storage usage– Daily backups of the control file (key component)– Daily backups of parameter file, tnsnames.ora, and listener.ora– Archived redo logs are backed up as necessary

– ALLOCATE CHANNEL to multiplex backup streams improve backup thoughput

– No Oracle encryption / compression / optimization


Copy to Tape


Copy to TapeKeep in mind

– Do not copy to tape using Data Protector „Post Backup“ copy– Best Practise to separate backup, replication, copy to tape and housekeeping for StoreOnce

– Limitation for SQL/DP regarding streams and devices (see QCCR2A61217 and QCCR2A58718)– When combining several SQL backup into one copy job


BackupReplicationHousekeepingStart of Replication WindowSpare Time for future growth or Physical Tape OffloadHousekeeping Window

Copy to Tape – Settings

– Copy only protected objects to prevent re-copying alreadprocessed objects

– Copy only objects not copied so far or with number ofcopies less than X– When using replication to copy from first StoreOnce to second

StoreOnce you would select 1– When copying objects to tape after replication has been

finished you would select 2

– Select timeframe or no time limit



– Select library filter to prevent copying from tape to tape(depending on settings in object filter)

– Try to avoid several libraries into one copy job



– Reset or change retention after successfull copy on StoreOnce

– Keep or change retention after successfull copy on Tape Library
