My aim is to copy incremental backups of everything on my internal hard drive to a USB hard drive I bought recently, and to have the USB hard disk be bootable (the BIOS on my motherboard supports this). Ideally, I'd like the backups to be incremental (not full backups each time). I'd also like the backing up to run in the background when the computer is idle, so that I can use Windows (XP) and applications without the processor grinding away.
I have read plenty of posts about backup and mirror software, and have looked good and hard at programs like Drive Image 7, but all of the programs I have found require full backups each time. (See solution title "Upgrading to bigger hard drive. How can i transfer all my data to include OS?" for a list of programs I have checked out.)
The programs I have tried meet some but not all of the criteria I would like -- namely, incremental backups, running when the computer is idle, and not locking up Windows.
I just thought I would ask if anyone knew whether my request is possible, before I settle for something else. (So far, Casper XP seems to come closest to what I'm looking for, but it doesn't do incremental backups and may not run when the computer is idle...)
I know hardware RAIDs are the best way to go, but this is for home PC backups.
Thanks very much
