What works fine? The restore? Are you not seeing the file corruption
anymore?
Yes the restore worked fine, but maybe it's not due to the fact that I
run fsck, but only because since those last 3 days, nobody was
manipulating the files while they were dumped !?
Someone else on this list (Paul Bijnens) told me that it is most
certainly due to that fact that I use dump to backup that partition ,
and if you read that :
http://dump.sourceforge.net/isdumpdeprecated.html
it could be a good explanation . so do you confirm that I should move to :
define dumptype root-tar {
global
program "GNUTAR"
comment "root partitions dumped with tar"
Anyway, if you have other suggestion , I'll appreciate, because today my
only solution is to move that backup from dump to tar . But will this
solve definitly my problem, will tar create other ones ? which (tar/dump
or soething else) is best finally ?
Thanks.

Hello
I've been saving partitions with amanda (dumps) for weeks now ...
unfortunaltly while needing to restore a file I got garbage :-(
For exemple, here's what I expected from the file I needed:
[EMAIL PROTECTED]
/var/www/html/server/settings/siteaccess/site_unite_server_en]
$ cat site.ini.append.php
[EMAIL PROTECTED]
/data1/restore-server/21-11-2005/www/html/server/settings/siteaccess/site_unite_server_en]
$ cat site.ini.append.php
$var3, 'templateValue' ) )
$var3 = $var3->templateValue();
$var2 = ( ( $var3 ) == ( 'enabled' ) );
unset( $var3 );
while ( is_object( $var2 ) and method_exists( $var2, 'templateValue' ) )
$var2 = $var2->templateValue();
unset( $var3 );
etc
You can see that it's completly different ! source codes have
replaces the initial php configuration code . It's as if one file was
replaced with an other one, perhaps inodes were mismatched or
something ...?
Is this problem already occured to someone on this list ?
Is amanda in cause , dump part, restore part ? , or it comes from
outsite amanda tools , from the system (here redhat 4 running
amanda-2.4.4p3-1) ?
I'am really confused about that problem, and cannot be confident on
my backups as long as I am not sure of what was the problem.
Since then, I fsck.ext3 -f the /var partition which caused me the
problems, it works fine now (last 3 days) , but I'am afraid of
beeing once again confronted to that problem.
Thanks of any help / sugestions .

You really think there is a "universal best"? Tar has its own problems
including increased time of backup and inability to handle some extended
types of file attributes.
Do your client OS/filesystem combos support ext3 snapshots?
Some recent ones do? If so, you could set things up to make a
snapshot just before the amdump, use dump on that non-changing
snapshot, then delete the snapshot after the dump.

No, I never tried ext3 snapshots ! I never heard of it :-( , any links
of where I can get information on that ?
I suppose it depends on kernel versions ? on my redhat4 it's
2.6.9-22.0.1.ELsmp.
indeed that might be a good solution .

Well, I have chg-zd-mtx working. In the process, I remembered why I had chosen chg-scsi originally. The main reason is that it detectes when a drive is requesting to be cleaned and will initiate a clean cycle when needed rather than by access count. It is too bad that neither ch-zd-mtx nore chg-scsi support RAIT as that is the way I would like to eventially go. My desire is to set up automated backups that back up everything that was changed on a daily basis and does a complete backup of the production file systems at least once a week. I also want to be able to do system file systems (/etc, /, /usr, etc.) on demand. Again, any configuration suggestions will be greatly appreciated. --Richard
Using ftape? Let me know.
Hello all, Is anyone actually using the ftape driver at the moment? I will be making changes to the amanda code, and want to make sure I don't accidentaly step on ftape VTBL support. So, if someone can volunteer to test out some patches over the next several months, it would be very useful. Even if you are not able to test the upcoming patches, please let me know if you are using ftape, and taking advantage of VTBL support. This will help me to understand the importance of this support going forward. If you are using the ftape driver, please post your comments on the Amanda forums here: http://forums.zmanda.com/showthread.php?p=20 Sincerely, --Ian Turner (Amanda developer) -- Forums for Amanda discussion: http://forums.zmanda.com/

I've not looked at the code, but if chg-scsi detects it via the status request it might show up in the "mtx status" output. If so, then it would be 'easy' :) to add that capability to chg-zd-mtx. > > It is too bad that neither ch-zd-mtx nore chg-scsi support RAIT > as that is the way I would like to eventially go. > Amanda does support a form of it own RAIT.

You can also force, with amadmin, a level 0 of any DLEs for the next amdump run. A separate config could be setup sharing many of the control files (disklist, indexes, curinfo, tapelist, changer.conf, ...) but with record set to no and a dumpcycle of 0 (always level 0). Then you could run amdump for that config and leave the standard one alone. Be careful they don't try to run at the same time. -- Jon H.

Someone reported here, a month or so back, that Jorg Schillings 'Star'
also worked with amanda, and I know its supposed to properly handle
that stuff, just never got a round tuit to try it with.
