The only thing that springs to mind is that you may be encountering an issue with snapshots of directories that are not in CIFS format, although I would think an error would be logged if that were it. See bug #15840. If that is the issue you can resolve it by setting an option to always create directories in CIFS format.

If that is not the problem, we'll need to have you open a call with tech support and provide some packet traces and detailed information about your setup.

Mark,

We are backing up a snapshot directory. We see random results. Depending on the run, between 6 and 15 subdirectories underneath a group directory are simply skipped. No errors reported.

You should probably back up from a snapshot, which avoids open file issues. See Paul Benn's NT backup paper for an example of this:

Note particularly section 5.

The only problem is that Omniback seems to skip about 25% of the data, with no error messages or anything. Using the regular Backup software that comes with NT works fine.

People tell me (I have to take their word for it - I'm not familiar enough with the product) that Omniback doesn't like to back up files that are open, so anyone with their Outlook, Word, or Excel apps open with files being edited over night are probably being missed.

That theory is pretty easy to test - see what files aren't being backed up.
