Differential backups count on the Archive flag being set for the file.
Normally backup programs turn off the Archive flag. And many
applications that modify a file turn it back on.

Unfortunately, this is not reliable for DBX files.

If the backup has to option to backup based on date modified, you can
use that for DBX files.

Normal Backup correctly backs up all Outlook Express .dbx files when
the
Outlook Express box is checked (which causes all .dbx files to also be
checked).

Subsequently, Differential Backup (with the Outlook Express box
checked)
does NOT back up any .dbx files after Outlook Express has modified
mail
folders (i.e. the .dbx files).

Differential Backup depends on a file (or folder) being marked by a
flag if
any change has occurred since Normal Backup. Is there something
different
about Outlook Express files that defeat Differential Backup? Outlook
Express
files are not on the excluded files list. Does anyone have a handle
on this
problem? Thanks.
