Oh there is some information on that topic in the Admin Guide. But it
is well hidden.

This is, how it works for me.

[root@afs1 backup]# pwd
/usr/afs/backup
[root@afs1 backup]# ls
CFG_backupfile  tapeconfig  TE_backupfile  TL_backupfile
[root@afs1 backup]# cat CFG_backupfile
FILE YES
MOUNT /usr/afs/bin/filemount.sh
[root@afs1 backup]# cat tapeconfig
50G 0 /dev/backupfile 1
[root@afs1 backup]# cat ../bin/filemount.sh
#! /bin/csh -f
set devicefile = $1
set operation = $2
set tries = $3
set tapename = $4
set tapeid = $5
set exit_continue = 0
set exit_abort = 1
set exit_interactive = 2
#--------------------------------------------
if (${tries} > 1) then
    echo "Too many tries"
    exit ${exit_interactive}
endif

if (${operation} == "labeltape") then
    echo "Won't label a tape/file"
    exit ${exit_abort}
endif
if ((${operation} == "dump")   |\
     (${operation} == "appenddump")   |\
     (${operation} == "restore")   |\
     (${operation} == "savedb")    |\
     (${operation} == "restoredb")) then
   /bin/rm -f ${devicefile}
   /bin/ln -s /vicepa/AFSBackup/${tapename}_${tapeid} ${devicefile}
   if (${status} != 0) exit
      ${exit_abort}
   endif

exit ${exit_continue}

I have two additional scripts. One expiring dump-infos from the backup-db
and the other to delete outdated dump-files.

Send me a mail, if you want to see them.

Yes, you do.
