I've successfully managed using the Windows Server Backup to backup 6TB of data to a 16TB iSCSI target but it keeps doing full backups. Unfortunately, this takes 3 days to complete so is practically useless. Is there a way to set it to do incrementals?
Also, probably linked but how can I do the same for backing up to an internal drive rather than a USB connected one as the same problem occurs. for some reason the backup always ends up being a full backup.
Why does wbadmin differentiate between internal and removable drives and is there a way to fake an internal drive as USB if wbadmin does indeed not like internal drives for backups?
