Ghost 14.0 incremental backup problem

Hello.

 

I'm having a problem with Ghost 14.0.5.34587, running Window XP with SP3 applied. The problem is that sometimes an incremental backup pauses at 1% for a very long time, and when it finally resumes, it seems to make an incremental backup that's the same size as a full backup. My backups are set to start a new recovery point set Monthly, and I backup, usually, every three or four days and never less often than weekly. It's almost like Ghost can't figure out that it already has a full backup. This has happened on my working drive, which I'd expect to change, and on another drive whose content almost never changes - indeed, on other occasions Ghost finishes backing it up in literally under a minute and the backup is very, very small.

 

My question is: why is Ghost getting "stupid" about the incremental backups and what can I do to correct it?

 

In case this is helpful, here's the configuration for my main drive backup that just did this yesterday:

 

Drives and backup destinations:
    $Main (C:\) to Z:\C\C_Drive015.v2i

Start a new recovery point set (base):
    The first time the backup is run in a new month

Scheduled backup time:
    No schedule

Event triggers:
    [  ] Any user logs on to the computer
    [  ] Any user logs off from the computer (Not at Shutdown or Restart)
    [  ] Application is installed
    [  ] Application is launched
    [  ] Data added to the drive exceeds:

Options:
    Backup name: 01 - DBak $Main (C:\)
    Compression level: None
    [X] Verify recovery points after creation
    Recovery point set limit: 5
    [  ] Search engine support
    [X] Prepend computer name to backup data file names
    [  ] Save backup files to a unique subfolder
    Description: Main drive with system info

Advanced options:
    [  ] Use password
    Encryption level: None
    Max file size: None
    [  ] Ignore bad sectors during copy
    [  ] Disable SmartSector copying
    [  ] Perform full VSS backup

Command files:
    Before data capture: None
    After data capture: None
    After recovery point creation: None

Offsite Copy:
    Disabled

Restore Anyware is not enabled for this recovery point.

 

(P.S. I turned compression off because I backup to an external hard drive connected via eSATA, and Norton's compression makes backups take an extremely long time relative to uncompressed backups - as much as twice the time.)

 

The drive in question has about 110GiB on it. Another drive as around 250GiB and a third around 7GiB. Each has had this problem at one time or another. Are these sizes too large for Ghost?)

 

Thanks in advance for any help you can provide.
