Hello,
First, I manage to install and work Amanda in a
redhat 7.1 (kernel2.4.3) with an ADR DI-30 with scsi
emulation(osst) and samba(v2.0.7)
Thank for all for many informations that i found in
the mailing list archive :))
--here is a lot of questions about the use of amanda
-i don't manage to make incremental backup of many
disk :(
into one tape (it seems to make a full backup each
amdump)
this my paramater of amanda.conf:
>dumpcycle 1 weeks
>runspercycle 7 days
>tapecycle 1 tapes
this is the disklist:
leto /home/toto comp-test-recover
cable /var/lib/amanda comp-user-tar-recover
cable /root comp-user-tar-recover
cable /lib comp-user-tar-recover
But none files was modified between two runs, so
incrementation level 1 is stupid or i understand
nothing with incremental method.

I understand that amanda needs more tape to realize
incremental backup with this configuration, but isn't
it possible to make a tape with a full backup and
incremental of a same disk in the same tape???
Actually i suppose when amanda reuse a tape, it
simply erase it, amanda does this if tape contains
other disks for an another configuration (ex:
DailySet2)???
Beside, i reaffirm a little bug with amrecover:
>EOF, check amidxtaped.debug file on localhost.
>amrecover: short block 0 bytes
>UNKNOWN file
>amrecover: Can't read file header
>extract_list - child returned non-zero status: 1
and little : 'mt rewind' is adviced before OR retry a
2nd extract with amrecover -> that's works well.
I didn't found into amanda commands for deleting a
disk into a tapes(not into the database definitely),
is it possible with amanda or other command???
Last point, i didn't found in the archive the user of
hardware compression in the DI-30, anybody can manage
this compression???(i just find an untested command:
"mt compression)
thank's by advance for yours responses.
PS: sorry for my english level
