I think it's all solved (probably I did not understood how archiving was working)...
I was thinking that i should run the snapcreator --action arch to do archive log deletion but I saw that configuring the archivelog command inside the config file at the end of the backup of oracle it will automatically do an "arch" step so it will delete older then 1 day archivelogs automatically while doing the backup.
Is this the correct behaviour? in the manual I think the archive part is not well documented... it just say how to config it but not that it will do archive automatically at end of database backup.
Yes Keith the only think I was misunderstanding is that I was thinking that I should use "snapcreator --action arch" after the --action snap (so I was thinking to put the run of snapcreator --action arch inside a ARCHIVE_CMDxx into the same config used by --action snap).
Instead it's already running the archive procedure after the backup was done. So it's all ok And a really nice feature
Yep --action arch allows you to run archive log handling only outside of SC. Mostly you wouldnt need this but if you wanted to handle archive logs outside of backup SC could do that. We recommend setting up snapvault or snapmirror and then deleting archive logs as part of backup. With SnapMirror make sure you set NTAP_CLONE_SECONDARY=Y or with PM NTAP_PM_RUN_BACKUP=Y so SC waits for completion and we know it is safe to delete archive logs. Otherwise archive logs could be deleted before we can copy them to secondary.
