I'm new to TI and just installed TI 10 and I'm still a bit confused on some things. My goals are (1) to be able to restore the complete system in the event of a catastrophic failure, of course, but also (2) to be able to get back previous versions of files or files that were accidently deleted, and I'm not clear on how best to do this. I understand that I can mount the disk image and get back individual files, but is this the best way to achieve my second goal? In other words, should I simply backup the partition image and keep incrementals/differentials of that........or should I ALSO do folder level backups of, eg, the MyDocuments folder, in addition to the partition image I have a fairly low volume of updates on my system and would aim to be able to go back, say, 2 weeks or maybe a month looking for old documents. My system is as follows: XP Pro PC's HDD = 80 gb USD HDD = 250 GB Also, do most people run incrementals or differentials? How long of an incremental chain is thought to be reasonably safe?
