I have an USB storage server attached to my network. It's a TrendNet TS-U100. Basically, it attaches to the network and you get to plug into it up to two USB devices. I have these 250 Gig HDs attached to it. Now, when I do my backups, I first have to du a full backup and then I get to do all the differentials that I want. I have the backups scheduled to happen at 9:00PM every day. I'd like to be able to tell TI that when one of the drives is full it should continue on the second one. Is that possible? On the drives, I had to create two parttions. One that is about 190 Gig and the other about 40 Gig. I did a full backup to the 40 Gig partition and then differential backups until the partition was full (eventually I got an error msg from TI stating that the HD is full). I then changed the scheduled task to do to the differential backups to the 190 Gig partition. Guess what happened when I run that task? It backued up to the 40 Gig partition. Just to make sure, I found the XML scripts that TI created and examined them to make sure that the target parttion is the 190 Gig. Everything was OK in there. So why did it back up to the 40 Gig partition?
