Re: [Bacula-users] Problem with restore
Try starting the Storage daemon with a -p option. It will then ignore certain errors -- however, when you are getting checksum errors, something has gone wrong and the SD will most likely either give up or crash. I try so, but the same error again. Unfortunately, I can't restore any file, because that checksum error. If I set -p to SD, it crashed anyway. :-( Is there any way to recover file or prevent this situation. It is first time, I need backup and I cannot get it. Thanks in advance for advice. --ogee --- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

[Bacula-users] Bad story
Hello, I would like to say, that I am very disappointed with bacula. The design is very nice, configuration si simple and clear, management is also good... BUT I would like to get backup from backup file for second time and for the second time I get (from different backup file) checksum error, it means that I can't use bacula, because it is not suitable for production nor normal use, maybe experimental. I am sorry about that, but it is not possible to use it, if it cannot give me backup files anyway. Hope, you are more lucky with using bacula! --ogee PS: I use bacula 1.36.(2|3) with PostgreSQL and store files to disk. --- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?

Re: [Bacula-users] Bad story
What on earth are you rambling about? Bacula is great, and covers all the typical (and more!) needs in a production enviroment! Bacula is, in my opinion, at this date the premiere solution for doing backups. I had thought so, but not know, because of problems, I have! One question to you Ogee: What does "BUT I would like to get backup from backup file for second time and for the second time I get (from different backup file) checksum error" mean? I have difficulties understanding what you are trying to convey. It means that I used to backup my filesystem with bacula for sometime and one day somebody need to restore some file, I would do that, but I can't because checksum error on backup file, next time (last Saturday) I wanted to restore somefile again (it was differnet backup file) and the same problem, so what can I do with perfect program like Bacula if I can't restore any file... --ogee --- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?

Andrew Paterson wrote: Hi Ogee, you say you are getting checksum errors. Anyway, you should still have a file restored - but it will possibly be corrupt just as it would be if you were using another backup system. Sorry, you're not right, because I CAN'T RESTORE file and it means, that I can't get/restore file from backup volume (file on disk in my case). I agree, that if file is being changed when backuping, that it would cause problems, the file I wanted to restore could not be changed, because it was file created by skript before backup (database dump), so nobody and nothing could write to it (possible yes, but no). This is YOUR problem not a problem with bacula (or any other backup system come to that). No, my problem is that I CANT'T RESTORE file from backup volume. If as I suspect this all means nothing to you, then I also suggest you pay someone to set up a working backup system for you. Maybe I should, but it's my job. ;-) Regards, --ogee --- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?

Re: [Bacula-users] Bad story
Still, the version information is not really precise... When I had had the first trouble I'd been using 1.36.2, so I upgrade to 1.36.3, it means my 2nd problem was with version 1.36.3. Ok, so we have to assume then that there is no possibility of problems with the file system or disk drives... still, I'd recommend a close look to the system's log and do a file system check. Just to be sure. Nothing bad happened. Ok, now I understand :-) Have you tried bls and bextract on the volume file? No. Have you tried other volume files, or other files to restore? Yes. Same problem. After all, this was only one file you tried to restore and it is some time ago. Yes, it is, but it was the first time trouble and 2nd has been the same, but with different backup file (volume I mean). Has this volume file ever been "moved around", e.g. put on DVD, deleted from disk, later been copied back? This is, from my experience, one of the best ways to break your backups - with DVDs you *always* should expect data errors. No, this volume was not copied, move or anything else. Where's that traceback from? bacula-sd I rather thought about starting the sd with debug outbut, something like bacula-dir -d 100 -c /etc/bacula/bacula-sd >> /var/log/bacula-sd-debug.txt so you can verify the process of the restore. Answer above. Now, I assume that you did some test restores when you set up bacula (or is this still the test?) and those worked. Have you changed anything in Yes, you right. between? Bacula versions, sd configuration, operating system, file systems, hard disks - anything? Because, apart from the problem of Yes, I've changed bacula version from 1.36.2 to 1.36.3 after first trouble. But nothing else. bacula aborting a restore when it encounters a checksum error, you really need to find out where that comes from. I would like to. From personal knowledge as well as considering the missing error reports I assume that this is not a problem created by bacula screwing up the data, but rather the result of data errors at a level "below" bacula. Hmm, as of one email above, where Andrew Paterson thinks I am absolutely stupid :-( talked about problem with file changed during backuping. I thought about that in different manner... It is possible if some file changed during backuping, that it would cause checksum error on whole backup file (volume?) if so, there is no way to backup when system is used and it is my suggestion from backup soft. I can't reboot to single user modes and do backup every day. ;-) Thanks to talking about that. I would like to find solution, if some exists. --ogee --- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
