I recommend use of differentials over incrementals even though they may be less space efficient.
If you have a chain of incrementals, and for some reason one of the files gets corrupted, you lose all changes after that link as well.
If a differential link fails, you can use next one instead (assuming next link does not reverse a specific change). So overall differentials have a higher data integrity.
Actually, I tend to agree with Jimbo45 as even with diffs, the weak link is the first full backup. I tend to just do full backups and keep two or three copies in case one corrupts.
Actually a better overall strategy is to have OS plus programs on one drive, and data on another. And then :-
Image backup the OS drive say weekly or monthly as suits (I always do one just before installing updates). By separating data to anothrer drive, then the OS drive does not change in size that much, and doing diff/inc backups is not really worth it. Also the full image backups are much smaller and quicker.
Backup data drive using File History Backup - you can set period as low as 10 minutes. This is a pretty automated system and works well.
Seperating data from OS also means recovery of OS is quicker and does not affect existing data.
