Hello,
we have configured O365 mailbackups to one of our virtual machine disks which would be almost full in few weeks from now.
We don’t want to shorten retention period (it’s 1 year and its our policy to keep it this long) so we would like to ask if its possible to somehow distribute/divide backups to separate disks?
Or easiest way would be to attach new disk and reconfigure backup location (backup destination in plan settings)?
O365 mail backup distribution
The best would be add mount paths to the existing disk library.
how to -Storage - Disk - < select the Disk library > -Backup locations - Add

You may also disable the backup location for further backups - this will put the existing mount path in read-only mode and continue running backups on the new Mount path.

Please note: All the Mount path should be online for restore/Recall services

However important note to keep here is tO365 mailbox data retention is not storage policy but message level.
