In a standard Backup Set/Subclient (File System agent), when you check Extend storage policy retention (Subclient Properties of… > Retention tab), it is possible to select one of two available modes: Job Based Retention and Object Based Retention. 

With Job Based Retention mode, there are some recommendations about archiving. With Object Based Retention, there is no recommendations about archiving, but the documentation cites stubs (Stubs are files that point to backed up and archived data). 

On Commvault world data functions as both a backup and archive copy, but It seems to me that both modes are related to File Archiving function, not traditional backup. Why are they here? I'm talking about a standard Backup Set, not an Archive Set.

Hi @Eduardo Braga 

Thank you for the question.

Please check out this Documentation page for Subclient Properties (Retention) that explains the differences between Job Based and Object Based retention in relation to a standard backupset:
Subclient Properties (Retention)

You cannot perform full or synthetic full backups if you select the Job Based Retention option.

Select Object Based Retention option to perform synthetic full and incremental backups.

Thanks,

Stuart

Thanks, Stuart, I’ll check it out, but just to confirm. We can use one of those modes even If we don’t want to archive anything. Right? We don’t want to move data to a secondary storage and use it to function as an archive copy.

Hi @Eduardo Braga 

That’s right, those options still apply with traditional backup copies where archive is not being used.

Of course, this is extended retention for the subclient, so will be specific only to that subclient, but if you wanted to apply extended retention more generally, you can set this at the storage policy level.

Configuring Extended Retention - at Storage Policy level.

Thanks,

Stuart
