We have an SBS 2011 server using a WBAdmin script to perform a bare metal backup on a nightly basis. When the server was installed, the backup was sent to a 2TB NAS and successfully ran without issue. The NAS has a backup folder that contains sub folders for each weekday's backup.
The server's backup set (one .vhd file for each day of the week, each being roughly 250GB) has since outgrown the 2TB NAS and we have replaced it with a 4GB NAS. The new NAS has the same IP address as the old NAS and the same folder structure. The NAS firmware is also up to date
The problem we are having is that ever since the switch to the new device, the backup is failing. In Windows Server Backup, the backup is shown as "Completed with warnings" but the details show that only about 70GB of data are being backed up.
I was able to successfully back up a subset of data but still cannot get the full backup to run. I've played with block size and disk format on the NAS without success.
Any thoughts or suggestions would be greatly appreciated
