[p4] Perforce Backup question

[Dan Bloch]

Hi, GC345C-

You're right that the server only has to be unavailable during the
checkpoint, but the rest of your process can be improved.

You don't need to, or want to, copy all of $P4ROOT.  All you want to copy is
the depot.  Everything else is already in the checkpoint.  And the depot can
be copied after the checkpoint, since it isn't a problem if there are depot
revisions that aren't in the database.  They're just ignored and/or
overwritten as necessary.

Finally you might want to think about rsync for your depot copy, which makes
copying even a large depot quite fast.

Regards,
 Dan
