My main drive (D:) has 500GB capacity. I also have two backup drives (both 250GB capacity).
I want to back up the contents of the 500GB drive and spread it across the two 250GB drives.
7-zip allows to store in .tar files and create multiple part files (example: 38 x 10GB .tar files = 380GB total). The problem is that it can only write the files to ONE drive. While one drive has too little space.
Is there some other tool (CLI maybe) that allows to write to one disk till it's full and then switch to the next drive?
FYI: a spanned volume is not an option. I require BitLocker which is incompatible with dynamic volumes (e.g. spanned, striped).
