Hello @elizabeta 

What is the highest retention in the CommCell? With a shorter retention it would be better to wait for retention expiry and then delete the library.

Hello,

@Zubair Ahmed Sharief the problem is backup DR (Disaster Recovery).

For some reason, the backup DR (Disaster Recovery) is placed both on the tape from the new Tape library and on the tape from the old Tape library. I do not know why. Last backup was 16.1.Retention is 30 days.

@Orazan thank you for the documentation.

Best regards,
Elizabeta

Just one question,

@Zubair Ahmed Sharief  May I ignore the fact that retentions from the previously backup have not expired and deconfigure the library?

Hello @elizabeta 

It is recommended the tapes moved and assigned to a working library for future restores. if the data can be ignored then it would be preferable to delete the jobs and run aging for manual cleanup. 

Ignoring retention would lead to issues in the future. 

DR backup jobs are WORM protected you may need to work with CV Support to delete these.

Hello,

@Zubair Ahmed Sharief 

There will be no need to Restore from the old tapes, I just want to completely remove the old tape library.

Can I just delete DR backup jobs that were performed on old tapes without the retention period having expired?

Best regards,
Elizabeta

Hello @elizabeta 

DR backups cannot be deleted before retention expires. For deleting DR backup jobs before retention is met,  Unlock code is needed which will be shared by support once a case is opened requesting the same.

for other jobs can be deleted and tapes also can be deleted. 

i would recommend to delete the tapes and then delete /de-configure the tape library.

Hello,

@Zubair Ahmed Sharief You recommend erasing the tapes. Can I simply delete the tape where the DR backup was located? Which is the procedure?

Hello,

The retentions on the old tape on the old tape library have not yet been expired, basically the situation is that every Monday DR backup is placed there (due to the busyness of the drive from the schedule policy on the new Tape library).
Is there any way to declare that tape bad and delete it somehow?

Best regards,
Elizabeta

Hello @elizabeta 

DR backup jobs make the storage device WORM (Write Once Read Many) until the retention is met. i.e. user cannot delete them as he deletes other client backup jobs. 

The library not being used can be mark for maintenance till the retention is met. Then the library can be deconfigured and deleted

Hello,

As we don't need the old tapes from the old tape library at all, can they be removed from the tape library and then deconfigure this tape library normally?

Best regards,
Elizabeta
