Subject  :  "True" Incremental Backups
Size(KB) :  1


As I understand it, the /BI (backup incremental) option relies on the 
destination directory already having previous versions of the files to be 
backed-up. I'm wondering if it is possible to have a "source" destination, 
distinct from the xxcopy destination, that allows one to have a "true" 
incremental backup that does not overwrite one's full backup.

My goal is to have an independent backup of the incremental changes so that 
I can rollback to a previous day's backup if needed. In this scenario, 
however, it is not *quite* as simple as providing a single "source" 
destination to help determine what changes have occurred. Any incremental 
backup directories that would have already been made would need to be taken 
into account. May I propose an additional parameter such as /SD 
"sd1,sd2,sd3" with the source destination paths ordered by date?

If anyone has some great tricks up their sleeve that basically accomplish 
the same thing, please let me know!

Thanks,
Jonathan
