It looks like you are doing file/folder based backups. Is there any particular reason why you are not doing volume-level backups of this server (which is the preferred method) ?
I am but we have a large share on this server and I wanted to be able to do file level restores. I also believe I has resolved this issue. But will wait until I can prove it before commenting.
You can still do file-level restores, even from volume-level backups.
