Backing up of archivelogs on a Physical standby
Given the backup and dataguard set up described below, I would like to know whether anyone believes it would be a good idea to backup the archivelogs on the standby database.
Our current production backup and DR strategy is as follows on our 11.2.0.3 database.
RMAN database backup to disk with a recovery window of 2 days.
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
Plus the following archivelog deletion policy.
CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO ALL STANDBY BACKED UP 1 TIMES TO DISK;
All backups go to TAPE via netbackup.
A physical standby exists for this production database.
