Win7 vs. WHS
Got Windows 7 and Windows Home Server (WHS)?
Got a situation where backup always fails with the message "unable to create a snapshot..."?
It turns out that the 100 MB "System Reserved" partition can get a swap file on it, which causes backups to fail because there isn't enough free space on that volume to create the volume shadow copy.
There are three main solutions for this:
1. Don't try to backup the system reserved partition at all. (Warning! This would eliminate the possibility of a full system restore from backup.)
2. Set up the swap file to NOT use the system reserved partition. (e.g. force it to use the C: drive only.)
3. Move the system reserved volume to a bigger partition:
a. Shrink the existing C: partition.
b. Create a new partition (smaller than 500 MB.) and map it to a drive letter, say S:
c. Open an Administrator-level command-prompt and type this:
bcdboot.exe C:\Windows /s S:
diskpart
select volume s
active
exit
exit
d. Reboot.
e. Delete the old "System Reserved" partition.
