    I'm trying to develop an offsite mirror and archive strategy for two
    linux boxes I have. I have an offsite machine with 3 disks. One is a
    big disk that I use for incremental archives. The other two disks are
    mirrors of disks I have in my primary linux machines. I'm using rsync
    to do the mirroring and tar to do the incremental archiving.

    My question has to do with linux recognizing the the file systems on
    the two mirror disks. Since they will have boot and swap areas, will
    this confuse the machine's file system? Can I just map them to
    something local and ignore the boot particians?

    My goal is to be able to take a disk out of my backup machine and plug
    it into the primary machine if it fails. I'll of course have to do
    database dumps on the primaries and restores on the mirrors to get the
    databases properly. Either that or have some sort of replication
    system which may be more bandwidth friendly.

    I'm also a bit concerned about file ownerships. I guess this is an
    rsync isssue, but I'm hoping it will use ownership numbers that will
    become relevant only when the mirror drives are booted. Is that what
    will happen?

    Mirroring/Archiving is a very complex issue, I know. Thanks for any
    help.
