Windows Server Backup Failing

I've been having issues recently attempting to do full backup on one of my
servers. While the C:\ backup as soon as the second partition starts, and
the backup fails with error
2155348010 (One of the backup files could not be created.). Please rerun
backup once issue is resolved.

I've tried restarting server, but the only information I get is "Block level
backup engine service has stopped."
I'm running Windows Server Backup 2008 Enterprise X64

Any ideas?

Hi,

This issue may be caused by some errors on the second partition.

I suggest performing a disk defragment and check disk on the second
partition.

If the issue persists, please shrink the partition by 5MB in Disk
Management and then extend the partition 5MB back by using diskpart.exe.
This will recalculate the partition table entry and correct the values of
NTFS total sectors.

If the issue still occurs, please understand that here is the Windows
Server Setup newsgroup. Therefore, we are not the best resource to
troubleshoot this issue. I suggest discussing it in our Windows Server
