Hi folks.
For some reason, i was under the impression that this was working well earlier, but it
appears to have stopped working after my monthly test (amanda version is 2.4.3b3
on the server, 2.4.2p2 on the clients). The only anomalies i have to report is that
occasionally i have run out of storage space for the backups and i have taken many
'tapes' out of circulation (but only by using amrmtape).
I am using amanda to backup various Linux clients to a central index and tape server,
which has a SAN server mounted using NFS under /var/spool/backup.
Every night, a shell script makes a directory that corresponds to the day's date, eg)
/var/spool/backup/dumps/20020718 and sym-links it to /var/spool/backup/dumps/data so
that the file driver will work.
I have tried a restore on a random file using the current date, and it worked.
However, today i tried to restore from a few days ago, and i got the following error
from amrestore (exact syntax follows, hostnames x'd out to protect the innocent).
(Keep in mind that when amrestore tells me to load the tape, all i really do is unlink
the symlink for /var/spool/backup/dumps/data and relink it to the correct subdirectory
corresponding to that date, right?)

========================== end logfile
I have check the permissions, and amanda owns everything in /var/spool/backup/dumps,
so i'm pretty sure it's not that. Indexes also seem to be working, otherwise i
wouldn't be able to list my files, right? i've also checked the directory, and the
files appear to be there (if someone wants more details i'll forward that to you later)
Anyone who can help me with this will really help to re-establish my calm.
thanks,
john.
