Hi Vizo,

If I use the UUID:blah format, vchanger can't find the drives.

I found on another post to this list in the archives (via google) that
the following method worked - but I'm unsure if any further problems
were encountered.

It seems to be a problem with libuuid or similar?

Ok I think you have magazine wrong

magazine = "UUID:Your UID HERE"

    Hi all,

    I'm in the process of trying to change my backup system from TSM to
    Bacula - and there are a few things I can't quite find the answers to.
    Mostly in regards to the interaction with vchanger.

    I use a few eSATA drives to move data to. I also do the initial full
    backups to this pool - then a nightly incremental.

    I've set up vchanger as so:
    # cat /etc/bacula/vchanger.conf
    changer_name = esata-changer
    work_dir = /opt/bacula/working/esata
    logfile = "/var/log/vchanger.log"
    log_level = LOG_DEBUG
    Virtual_Drives = 2
    slots_per_magazine = 10
    magazine_bays = 1
    automount_dir = /mnt/vchanger
    magazine = /mnt/vchanger/a7122eae-bf9a-4b09-a67f-68db60cee026

    It seems I can't use UUID:a7122eae-bf9a-4b09-a67f-68db60cee026 as the
    magazine (maybe that leads to my problems restoring later on?) as
    vchanger continues to error out when I try.

    bacula-sd.conf is almost straight from the docs:
    Autochanger {
      Name = esata-changer
      Device = esata-changer-drive-0
      Device = esata-changer-drive-1
      Changer Command = "/usr/local/bin/vchanger %c %o %S %a %d"
      Changer Device = "/etc/bacula/vchanger.conf"
    }
    #---  drive 0 of the esata autochanger
    Device {
      Name = esata-changer-drive-0
      DriveIndex = 0
      Autochanger = yes;
      DeviceType = File
      MediaType = File
      ArchiveDevice = /opt/bacula/working/esata/0/drive0
      RemovableMedia = no;
      RandomAccess = yes;
    }
    #---  drive 1 of the esata autochanger
    Device {
      Name = esata-changer-drive-1
      DriveIndex = 1
      Autochanger = yes;
      DeviceType = File
      MediaType = File
      ArchiveDevice = /opt/bacula/working/esata/1/drive1
      RemovableMedia = no;
      RandomAccess = yes;
    }

    bacula-dir.conf is almost straight from the docs as well:
    Storage {
            Name                    = esata
            Address                 = bacula.crc.id.au
    <http://bacula.crc.id.au>
            Password                = "mypassword"
            Device                  = esata-changer
            Media Type              = File
            Autochanger             = yes
    }
    Pool {
            Name                    = esata
            Pool Type               = Backup
            Storage                 = esata
            Maximum Volume Bytes    = 40G
            Recycle Pool            = esata
    }

    Now, I've been using BAT to look at the director and I firstly have the
    following specific questions:

    1) I have 10 inital slots for volumes on the eSATA drive. 10 x 40Gb =
    400Gb. As the drives are 1Tb (mostly), will new volumes automatically be
    created as the other 10 reach full? Do I have to manually create the
    number of volumes up to X (ie a full drive?)

    2) When I do a restore, will I get prompted to insert the esata drive
    for vchanger to play with? My initial experiments show that the restore
    terminated with the following errors:
            17-May 19:03 bacula.crc.id.au-sd JobId 58: 3304 Issuing
    autochanger

    I can't seem to find much on the who/what/where/why of this. I have
    however revisited the config from scratch, wiped the bacula DB and am
    starting fresh with a new install for my current lot of trials.
    (therefore this config didn't quite match the above).

    Any good suggestions or tips on gotchas for a new Bacula user?
