I'm having trouble with Windows 7 Backup and Restore. Whenever I try to run a backup for myd rives, it gives me this error:
Very annoying. Now I've searched for the error code, and tried restarting, yada yada yada, but nothing has worked.
This is my backup setup:
I have two internal drives (128GB SSD, 512GB HDD) that are backed up to a third internal drive (2TB HDD). In the past, this has worked fine, but now it just stopped working.
It doesn't work even if I:
- Deselect the D:/ drive | same error
- Deselect the C:/ system image option | error: Requested system device could not be found (0x80073BC3)
- Both of the above | error: 0x80073BC3
- Only try to backup the D drive | error: 0x80073BC3
I am not able to mark the partitions as active (grayed out), as it is suggested here.
I hope the experts here can help me, but I've been using a different backup utility so I'll be okay for now.
EDIT:
I'm adding the cmd responses for VSS and chkdsk.

VSS prints out about 16 shadow copies. The full results for it are here.
I forgot to mention that I formatted my backup drive, but that didn't help.
I have about 55% of my space left on C:\, and 23% of my D:\ drive left.
Best Answer
A couple of most likely causes:
You probably have accumulated too many shadow copies that weren't properly disposed of by the backup. This sometimes happens. So try and list them with vssadmin.
You are running low on a free space on C:\ and D:. There's no clear guidance on how much space it needs, but having at least 10-20% is generally a good idea.
All in all though, VSS is just ... finicky. It has a lot of dependencies, which in turn are also dependent on other things and so on. If anything in this pyramid break or hiccups, VSS starts spitting out incomprehensible and frequently ambiguous error codes. So even if you google "VSS + ", there'll be a bunch of solutions, each working for just some cases. There is a way to troubleshoot VSS with diagnostic logging, but it is very tedious and it doesn't work reliably. Reimaging the system is simply faster.
