Rotated USB drives

[peeky1323]

Hi,

We have a stand alone agents backup up to 2x USB drives. It seem when ever a drive is swapped out Veeam does a full backup and starts a new chain. Is this expected behaviour? For example,

Drive 1:
Day 1 Full Backup
Day 2 Incremetnal
Day 3 Incremental
Day 4 drive swapped

Drive 2:

Day 4 Full backup
Day 5 Incremental
Day 6 Drive swapped back to 1

Drive 1:
Day 6 Full Backup
and so on

We have swapped the disk out 6 times and have 6 full backups on each disk.

This continues until the drive fills up and backups fail.

Thanks,

Matt

Hi Matt,

That's expected behavior, you can review the article called "How Repository with Rotated Drives Work".
Also, you can reduce the number of restore points to keep in the retention policy to avoid the backup fails. Thanks!

Matt,

Dmitry is right, for Backup and replication but you are talking about the Veeam Agent for Windows here I assume
https://helpcenter.veeam.com/docs/agent ... tml?ver=20

According to the above: After you swap drives again, Veeam Agent for Microsoft Windows detects if there is a backup chain on the currently attached drive. If the backup chain exists, Veeam Agent for Microsoft Windows continues the existing chain: it creates a new incremental backup file and adds it to the existing backup files

So in your scenario, it should actually continue the backup chain and not create full backups again, unless there is something wrong with the backup chain.

Please create a support case ID, post it here for further reference and let us know the outcome after the investigation of our support engineers
Thanks
Mike
