Dave,

There have been some excellent replies to this one, but I just want to
clarify the difference between using uvBackup and an OS level backup.

The OS level backup does not understand the UniVerse file system. As a
result, unless you can *guarantee* that the file system is quiescent (e.g.
by breaking a mirror or suspending the database) you run the risk of storing
a file that during a point of reorganization - in which case it will be
useless. uvBackup on the other hand is a UniVerse facility that respects the
lock handling and contention management and will back up at an item level
with no danger of file structure corruption (though it does not of course
guarantee transactional integrity).

It is also potentially useful in that you can restore specific items: though
I've never done that as the syntax seems to outweigh the advantage (normally
I would just restore a copy of the file and copy items across).

Finally, if you are working under Windows you need to be doubly careful
about OS level backups. The regular NT backup simply ignores any open file
(without flagging these up as an error). You would need something like
Veritas to ensure that open files get saved.
