I'm thinking of switching to ATI for my backups, and I'd like to know a few things about how incremental backups work in ATI. I hope you folks can enlighten me. Until now I've been using XXClone to make weekly backups of my entire system disk to a partition on a larger external drive, rotating weekly between two alternating backup partitions. Initially I did a full drive backup, but after the first full backup I have been able to stick with quicker incremental backups. XXClone Pro will do an incremental backup that changes only the modified/added/deleted files to make the backup copy the same as the source copy. I've had good success with XXClone, and in the past I have successfully cloned or restored WinXP systems from one drive to another. Recently though I had a problem with when I cloned my system to a larger hard drive - it broke the Microsoft Installer patch database somehow. I used Seagate DiskWizard instead to do the clone, and that worked correctly. So of course now I'm thinking of switching to ATI for my regular backups. Will ATI do incremental backups the way that XXClone did? That is, I have an existing backup partition that contains a complete copy of my system disk, and I want to update it with just the changes. Will ATI let me make multiple incremental backup sets on top of an initial full backup? That is, I make a full backup at the start of the month, and then create a weekly incremental backup set with just the changes from the last backup.
