How many is ultimately up to you, as you know better than we how often and how critcal the backed up data is. Or rather, if a restiore was needed how far back you could go without loosing much.
But look at it this way.
So long as you have the host Full Image, any differential is just as good as a full back up, only smaller.
Lets say you do the Full Image, and 6 differentials, then start a new chain. Thats equal to a full backup daily.
But, with the differentials you could go back and delete certain ones. Say, keep the Full backup, and every other diff. and it would not hurt a restore.
You can literally keep as many as you want. Its really going to be more about how many you need.
The other good thing, provided backup space isnt a issue, is that with ATI2012 youll be able to restore single files with the right click context menu that will include versions in each diff, across all chains.
I never thought much about it untill I accidently overwrote some game saves I didnt mean to. and didnt immediately realize I had.
It saved me by just restoring that 1 save file to a previous version 3 days prior.
So while sometimes it may seem to much, if something changes often, its a good idea to have several versions back.
