Hello,
I have a virtual 2012 R2 file server running on ESX 5.5, and recently I've started to have the following problem. Every night the server will run a backup onto an iSCSI target at the scheduled time, but each time it's proceeded by the following event in event viewer:
Event ID 24:
Backup started a fresh backup for volume '{00000000-0000-0000-0000-000000000000}' ('Esp') : [Reason: 'Volume size changed']. This may cause loss of older backup versions when backup completes.
True to its word, Windows Server Backup then trashes the previous backup, and completes a new one. The destination is 4.1TB big, and it's currently only using just over 1.3TB, so space isn't an issue there.
I don't know when this started as I only get email notifications for event IDs which signify failure, all I know is that I can only perpetually restore files from the previous night. This wouldn't be too bad if it was for just disaster recovery, but I work in education, and Students / Staff have a habit of loosing things!
I tried deleting the schedule, and then re-creating it (letting WSB format the disk), but no joy. Is there anything else I can try?
Kind Regards,
Mike
