Cannot Add File

[Nine Lives]

The backups have been working well for weeks. All of a sudden I get the message:

[9/15/2011 3:57:41 PM] Error: Backup aborted. Reason:

Cannot add file "C:\Users\SEFreeze\Desktop\Wallpaper\HPIM0144.JPG" to "G:\C-Backup\Backup C\1_C.zip".

Zip error: G:\C-Backup\Backup C\KPZF1E1.tmp

Backup aborted at 9/15/2011 3:57:42 PM with 1 error(s), 0 warning(s)

Any ideas as to why this may have occurred?? I fails on both types of run: Scheduled and Manual.

I figured this one out. Although the backup i50 GB and the disk is 1 TB, I discovered that the disk space was too low. I cleaned up the drive and - voila! - I am back in business!
