We are using a NAS unit with iSCSI to backup to a removable hard drive. The hard drives have three LUNs associated with them. We are using SBS2008's backup to a LUN, and two other Windows 2008 Servers are backing up to the remaining two LUNs using Windows Server 2008 Backup. Each LUN is used by a single server for Windows Server 2008 Backup. Everything is working great, but, since there is so much room available for backups, it will be a long time before a LUN will run out of space. My questions are the following:
What will happen when Windows Server 2008 Backup detects that there isn't enough room for a backup?
Will it simply fail or will it rewind to the beginning of the hard drive and continue?
Will I have to go into Windows Backup and delete backups? If so, how is this done?
Is there any difference in end-of-media behavior between SBS2008 and Windows Server 2008 backups? I'd expect that they behave identially since SBS2008 backup uses Windows Server 2008 Backup.
From what I have seen, it will be a long time before I encounter this issue, but I'd like to know what to do when it happens.
I appreciate your answers!
