I have windows XP SP2 with all updates.
One 200 GB SATA disk partitioned into C and D. One external 250 GB SATA drive as F.
I am trying to do incrimental backups of C and D every night to F with windows backup. It always works, but almost always has gives me this error:
Error returned while creating the volume shadow copy:80042308
Reverting to non-shadow copy backup mode.
I notice that if I restart the computer, the next time the backup runs it runs succesfully (i.e. using shadow copy). However, any subsequent backups give me the error. I have nothing else scheduled to run at the same time the backup is running, so CPU and DISK I/O should be almost nothing.
Every time this fails, my system log contains two entries:
ID 20: The shadow copy of volume D: was aborted because of a failed free space computation.
ID 20: The shadow copy of volume C: was aborted because of a failed free space computation.
C: currently has 77+ GB free
D: currently has 30+ GB free
F: currently has 55+ GB free
Thank you for your help.
