No compression option for image backups available in RMAN No storage conservative way to store multiple copies of same data item in RMAN. Host interference in tiering to ternary storage. Full/Partial replication of multiple databases using same backup. Restore need of base backup in case of an erroneous recovery during point in time recovery. Replication of disk backup to remote destination. Orhan BIYIKLIOGLU feat Husnu SENSOY9

It was always a hard issue to clone a database before 11g. Active Database Duplication makes it impressively easier in terms of configuration. But it is still a time consuming event. Orhan BIYIKLIOGLU feat Husnu SENSOY17

Did you ever rollback a single database tablespace to get a previous state of a table before an erroneous update operation ? How do you decide on parameter for UNTIL clause ?

Use IB or 10 Gbit network fabric to access unified storage systems. Remember that current bottleneck on Unified Storage Systems is PCIe 1.0 I/O interconnects.

Choose 64K/128K blocksize for your Image copy Backupset archivelogs Remember that dedup and compression options for shares are CPU demanding operations. Don’t use them unless you need them. Use RMAN compression whenever possible unless you have a host CPU bottleneck because it will increase you effective write speed. 11g Release 2 : LOW or MEDIUM 11g Release 1 : LZIB Don’t use fast recovery with SWITCH option Unless your production storage has a comparable performance with unified storage systems For fully parallelise the backup of BIGFILE datafiles use SECTION option with 11g Release 1. Orhan BIYIKLIOGLU feat Husnu SENSOY24

Design multiple shares differentiated depending on your need. You can asynchronously move your backups to tape drivers from unified storage systems But since those backup copies will require a restore from tape before database restore or SWITCH operation. In case of a conflict with routine backup activity, use read-only snapshots as tape copy source. Cleanup unnecessary snapshots & clones. Orhan BIYIKLIOGLU feat Husnu SENSOY25

A system already running on NFS or another storage with a comparable performance. A single disk copy is sufficient. Quick recovery from failure is neccessary in case of a primary storage loss. Database size very small with compared to Unified Storage Systems pool size.
