Crash during backup

Hi Folks,

My server is crashing during the backup, not every day but 3 to 4 times a week.

The server does not respond on any command. After a reboot through APC the server comes online.

When I look at the backup log I see that the server crashes at zipping an account, every time another account.

I did this:
- More RAM: 512 --> 1024
- Another processor: Celeron --> P4
- Another FTP server

Nothing seems to work, i'm running CentOS 3.4. Can anybody help me solving this problem?

Greetings,

Edwin
 
Zipping as in when backups are run?
If so you can temporarily disable backups until you have found a better solution.
Which compression program in particular? Tar?
Is there any particular minimum size of the backup needed to be done that is seems the process get's out of control? or any particular set of users which seem to keep triggering the problem?

What level are you running these backups from? (admin, reseller...)

I assume the process ends up eating so many resources that it brings the server down?
 
Are you out of space in the directory that the zip is being created to? That would be the most likely reason.

I'm working on this problem for the customer right now. There is no lack of space in the place where the TAR is stored. On the other hand, I haven't been able to reproduce the issue. I've done the following:

Ran a Admin-level backup using the "Run Backup Now"-button. This went great!
Ran a Admin-level backup using the "Run Backup Now"-button, and had it transferred to an offsite FTP-server. This went great too!

Installed the backup-cron, called up root's crontab (crontab -l) and ran that command, but it didn't do much at all. Seems that the cron isn't working. When ran the command I started "top" to monitor the processes, and i saw a flash of tar and gzip coming by, but they vanished in a couple of secondes, and then nothing happened anymore.

Is it impossible to run the command found in cron by hand, or am i forgetting to pass some variables to sysbk? Any advise would be greatly appreciated!

What does the sysbk log file tell you?

It can be found at:

/usr/local/sysbk/status.log

Whoops, my bad... Forgot I allready made a backup that day, and couldn't make an other one in the same folder. I just tried sysbk, and it was working fine. So up until now I haven't been able to reproduce the issue. When I do, I'll make sure to inform you.
