Home -> Community -> Mailing Lists -> Oracle-L -> RE: Archive files and their Management
I'm up for my backup and recovery class here soon, but this conversation has
brought up questions
that I think some of you wouldn't mind discussing anyway. I see where
implementing archive logs
requires that you modify the database startup procedure to turn on archiving
before opening the
database. At this point the DBA should do an immediate "baseline" backup
(orafaq =)) which
implies a hot/online backup. I am curious how this goes with point in time
cold backups. ie. DBA
does a cold backup opens the database in archive log mode. Can you apply
accumulated archive
logs to a restore from cold backup ? perhaps there are issues with the
control file information.....

theoretically only the archive files after the backup started are needed. but there might be issues of a corrupted backup, and to guard against that we have a policy of keeping archive files for one week.
you should also keep checking your backups by restoring them to a separate location periodically

Our policy is to keep archive for the last 2 days at least. We are doing daily backup so it gives us the option to restore from the last backup or the one before without restoring archive logs.

Greetings Gurus
Just wondering.......
Our archive log's directory has grown substantially and space is becoming an
issue.
How do you know which archive files is safe to delete?
In other words...
Do you delete all archive files older than the last backup?
Should you keep all archive files until it is obviously pointless?
Please advise.
Many thanks
