Hi!
don't know if I sent this twice! in that case, pardon me for the inconvenience.
I backup a windows big volume with about 30000 files using, among other,
smbclient.
so in my disklist there lies
amanda.my_domain.com //principal.my_domain.com/DADES
nocomp-user-gnutar
the dumptype definition used is:
define dumptype nocomp-user-gnutar {
comment "Principal samba backups"
program "GNUTAR"
holdingdisk yes
index yes
options compress, index
priority high
}
as you can see I DO use compression.the tape type used is:
define tapetype principalHDD {
comment "30Gb disk"
length 37500 mbytes
}
I have some firewire external HDDs with five 37500 mbytes 'tapes'
when trying to restore the backup I have two problems:
amrecover> add io3data
Added dir /io3data at date 2004-11-05
Added dir /io3data at date 2004-11-01
amrecover> extract
amrecover: warning: using /dev/null as the tape device will not work

amanda keeps processing the 27Gb file for about three or four hours and then I
got this error:
tar: Unexpected EOF in archive

in the amidxtaped debug file I have:

I was wondering if someone already had this problem and how would you solve it.
moreover, I'd like to be able to restore some files a bit faster. any ideas? I
think the whole 27Gb file is parsed by tar in the restoring process , so
splitting it in smaller independent chunks will help.
BUT I cannot make, let's say 30 wilcarded entries in my disklist of the style:
hostname /path/to/large-volume/[A-B]* user-tar
hostname /path/to/large-volume/[C-D]* user-tar
...
(found in the amanda faq'o'matic
(http://amanda.sourceforge.net/cgi-bin/fom?_recurse=1&file=5)) because I'm
using smbclient to backup and these directories are highly dynamic.
any ideas?
TIA
sam
