I have been running the built in backup software on a 2012 server. Today I noticed that I only have 3 days of backups.
The server is 2012 running Hyper-V with 6 VMs. I had the backup software configured to backup all the VMS and a bare metal backup to an external 2 TB USB drive. I have been looking at the event logs and search the web without much success up to this point.
The event log does have the following information message:
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.
Any help would be appreciated.
