Hi guys,
I have some problem with the new backup feature on proxmox.
I scheduled backups with snapshot mode every morning at 5:00 am and it's the second time that the server is totally frozen. I can't do anything, i can just switch off the server with the button.
I haven't got anything on the logs. So... if anyone have the same problem or solution, tell me what ;)

  1. how many gig´s do you backup?
  2. KVM or OpenVZ containers or both?
  3. where is you backup location? local or remote?
 
- how many gig´s do you backup? : 2 of 32Gb and 1 of 64Gb

- KVM or OpenVZ containers or both? : KVM

- where is you backup location? local or remote? : Local


Since the backup feature is enabled, it failed 2 times and 3 times it works...

Thanks for the quick reply :)

try to run vzdump manually to see what happens

(see /etc/cron.d/vzdump what command gets executed)

how big is your root partition, by default it is maximum 100 GB which is to small in your case.

My root partition is 33Gb but the backup files are 14Gb so i have enough space.

and again, where is the backup location? local, but which path?
 
i have made a directory called "backup" on /root

But i think it's not the problem because the backup works fine in most of time...

Maybe en temp file problem, even if you tar'ed the backup file maybe you got not enough space at some moments...

Try to install monitoring tool like Cacti/Munin/Mrtg to take an history of your disk space...
 
I already have a Nagios server that monitors my disk space and on the graphs, on the backup period, the root partition is not full.

Edit: I have to go so I will tell you tomorrow how the next backup happened

Thanks again :)
