I have a customer that has an XP/sp2 computer that they'd like backed up daily and want to insure short downtime in case of disaster. They'd also like to be able to recover single files from time to time. They have 3 sata drives mounted in a removable caddy. At the end of the day, they'd like to initiate a backup of their entire drive to the backup drive and then take it off-site for safety, replacing it with another of the three. I considered doing a ghost or clone of the drive to the removable, but it appears that with TI there's quite a bit of intervention required, including a reboot. Also, it appears that the target drive has to already have a partition on it otherwise the clone tool can't see it. Could be a hassle if new drives are added to the cycle. Doing a weekly disk image backup with daily incrementals then rotating the drives may work but I want this to be a no-brainer for this customer. Is there any command line interface to permit a simple "backup now" desktop shortcut when they're done for the day? Using TI for most operations is a lengthy and very decision-intensive process unless defined in the scheduler. I think I want to avoid using the Secure Zone feature because of their novice level. They'd have to know about adding it if they introduced a new drive to the cycle and it'd be invisible to the OS - meaning they wouldn't be able to check the volume label of the disk nor it's remaining capacity from "My Computer". TI doesn't tell me the backup won't fit until it's too late - at the end of the backup it says "not enough disk space". Given all this, what method would be best to use to create full backups to the three "generations" of external disks?
