Hi,
I have a incremental backup level 0 on sunday and incremental backup level 1 along with week. The retention policy is 1. The size of backup file is 38GB, and recovery_area of 40GB. My question is: the retention policy is applied before the new backup? In other words, the when the old backup is deleted? Before or after the new backup? The recovery area is enough?

Thanks,

Why don't you just try it instead of relying on an answer in a Forum, answser which may be wrong and which you have to test anyway?

Regards

Hi,
I make a test.
1. Resize flash recovery area to 60Gb;
2. Configure retentio policy to 1;
3. Execute DELETE OBSOLETE command on script of backup.

Result: The old backup set not is deleted.

Can someone help me.

Thanks,

Hi,

"CONFIGURE RETENTION POLICY TO REDUNDANCY 1" means the One set of backup copy will be at your disk.[Correct me if I am wrong].

So DELETE OBSOLETE will not delete the backupsets.
You can try the below approach:-

1. CROSSCHECK BACKUP;
2. REPORT OBSOLETE;[To check whether any obsolete backup exists or not]
3. DELETE OBSOLETE;

Thanks-
P

Hi,
I have a bash script that run every sunday. Its like this:
...
echo "Running rman"
su - $ORA_OWNER -c "$ORA_HOME/bin/rman log=/dados/backup-rman/log-rman/log-rman.txt" <<EOF 
connect target /
connect catalog $CATALOG_CONN
backup incremental level 0 database plus archivelog delete input;
delete obsolete;
host "exp rman_user/rman file=/dados/backup-rman/files-rman/rman_cat.dmp owner=rman_user";
exit
EOF
...


I have to delete old backup set. I have to put "crosscheck backup" and "report obsolete" too?

Actually, I have to access the RMAN and entry delete command manually.

Thanks,
