Incrementally updated backup and EMC NMDA
Hello Everyone,
I'm kind of a newbie in setting up networker module for oracle, to backup database to tape. We use the oracle's suggested backup strategy to backup DB to Disk first using the incrementally updated backups with recovery set to 3 days (RECOVER COPY OF DATABASE WITH TAG ... UNTIL TIME 'SYSDATE-3') , which helps us to recover DB to any point in time using the backup files in disks vs. going to tape. After backup to disk, we backup recovery area to tape nightly. However, we do want to maintain backup Retention Policy of 1 month. Couple of questions,
1. If i set RP to recovery window of 31 days in RMAN, then backups don't obsolete at all. this forces me to set RP in networker and they don't recommend setting RP in both RMAN and networker. how is this done generally to obsolete backups from tape as well as rman (catalog in CF) with above strategy. perhaps in this case i should set RP in netwoker and set RP in RMAN to none and rely on crosscheck and delete expired commands to sync with RNAM catalog.
2. Wondering if nightly backup of recovery area to tape is going to take incremental from previous day and NOT full backup. The reason i ask is, i do not want the tape to do full backup of FRA every day cause full backup datafiles change once in 3 days based on the until time set. is there an option do set in networker to do incremental only or that's the default.
Thanks in Advance!
