Hi
Is there a tool to lock the db such that rdif-backup will not use the
destination - i know rdif-backup does it.
I want to lock the db and then rsync the destination offsite and then
unlock the db.
With "db" you mean the rdiff-backup destination directory?
yes, I would like to lock the rdiff-backup destination such that
rdiff-backup will not use it until after the rsync offsite has finished.
I guess you will have to use a wrapper script for your rsync job and
your rdiff-backup job that does the locking (and obeys the lock).
If you start both jobs at the same machine, it's easy:
Put this at the start of each script - it will then exit when another
instance is running.

#!/bin/bash
