I believe you're asking the wrong questions and are likely to run into complications. You don't know when BIND will merge the journal, or that rsync will atomically snapshot the zone file and the journal. So you will get a coherent copy of the the zone file - but it may be stale. The journal may be earlier or later than the zone file, or it may be incomplete. This means that a restore may have the slave serve stale data - until it queries the master for any updates & if necessary, fixes the journal file. If the master happens to be down, this is especially suboptimal. So I would exclude both files from rsync, and use another approach to save a coherent copy of the zone file(s) in my backup procedure.
rndc freeze can cause all journals to be synced and files saved. You can call this before backup and call rndc thaw after. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
