Both incremental and differential backups depend on a first backup being
done. That first backup creates a copy of all items you select.
Subsequent backups will create smaller archives that record only the
changes/additions since the first backup.
If you need to create your data, restore the initial backup first. Then
layer on the subsequent data sets.
Personally, I don't care for this style of backing up that chains
together several different archives to arrice at a destination. If part
of the chain breaks -- you could conceivably lose quite a bit.
To me, it makes more sense to keep a few sets of full data backups on
hand. Example:
Create backup for week 1
Create backup for week 2
Create backup for week 3 and delete week 1
Create backup for week 4 and delete week 2
.... and so on.
The URL below explains a little bit more about the different backup
types. It also takes you to a section of TechNet that discusses NTBackup
in great detail. I think you'll be able to find the other information
you are looking for there too.
