[OpenAFS] Backup operations...

[Charles Karney]

Brief tape backup instructions:

    assume AFS server is afsserver.cell.com,

    assume tape is connected to AFS server on /dev/nst0 and has approx
    100GB capacity (this can be an overestimate in the case of a drive with
    compression).

All of these steps should be carried out as root on one of your AFS servers
(so that -local works).

Configuration:

    echo 10G 0K /dev/nst0 0 > /usr/afs/backup/tapeconfig:

    backup -local
    addhost afsserver.cell.com 0
    addvolset all
    addvolentry all -server .* -partition .* -volumes .*\.backup
    adddump /full -exp 1y
    adddump /full/monthly -exp 1y
    adddump /full/monthly/weekly -exp 2m
    adddump /full/monthly/weekly/daily -exp 14d
    quit

Prep for dump:

    vos backupsys -local

The actual dump

    In window A:
        butc 0 -local

    In window B
        backup dump all /full 0 -local

butc will propmt for tape changes.  screen is handy for managing the
multiple windows.
