yes, this is what I observed. Your comment about matching expression
makes much sense. I should have thought about that first.
I will test it next a similar situation occurs.

A funny coincidence: I've setup an offsite archival config
for amanda-2.4.4p3 (soon to be upgraded) and due to a silly
mistake of mine one DLE didn't make it to tape. Rather than
doing it over again I just labeled another tape and did
su amanda -c "/opt/amanda/amanda6/sbin/amdump archival-conf6 bullcalf \
/data/ipl/ipl10/broche/colindata"
The DLE from the disklist:
bullcalf /data/ipl/ipl10/broche/colindata /data/ipl/ipl10/broche/colindata {
tar-archival
exclude append "./ave/*"
exclude append "./brainvisa/*"
exclude append "./pd/*"
exclude append "./t1/*"
exclude append "./t2/*"
exclude append "./vaisseaux/*"
}
Problem: that DLE has exclude list and it seems that all excluded
subdirs are making it to tape. Is this the normal/expected behaviour?

I think a difficulty is that there are several possibilities. 1. Don't do anything but run your normal amdump schedule. Amanda knows the status of the failed server and will bring it up to date the next amdump run. 2. Run an extra amdump as soon as you have the server online and send it to tape. For this you should have a tape in the drive while amdump is started. It can be the next tape from your normal rotation or an extra "new" tape. The next time around in the tape rotation, the new tape will be expected in the same order. But if you like, you could mark it for noreuse so that does not happen. 3. Run an extra amdump like above but without a tape in the drive. This will cause the dump to collect on the holding disk for later taping. The later taping can be done with amflush, or if configured appropriately it will happen along with the next amdump. For this to work well you need a holding disk large enough to hold the extra dump plus the normal load of the later amdump; the reserve parameter must be set to allow the holding disk to be used for level 0's if needed (say 10 - 50%); and the autoflush parameter must be set to yes. If you are backing up many clients you may find it a ?common? occurence that one or more clients, or some DLEs are not available at the time amdump runs. For extremely critical data you may want to do the extra amflush. If so, make sure it will have completed by the time your regular amdump does run. Alternatively consider waiting for the next regular amdump. The missed DLEs won't upset amanda. It will adjust and do the "right" thing the next run. -- Jon H.

Have you read the chapter about Amanda in "UNIX Backup & Recovery"? It gives a pretty good overview, and is available on the Internet. The link is on the amanda.org web page.
