I am trying to backup a nagios installation on my proxmox 1.9 Think the clue is in the lines

101: Nov 14 04:04:30 INFO: rsync warning: some files vanished before they could be transferred (code 24) at main.c(1058) [sender=3.0.3]

Can anyone provide any pointers

Thanks

This is not the problem and is quite normal - you can ignore that info.

This is the real problem. Maybe you have an open console ('vzctl enter') while trying to backup?

Hmm not sure what you mean by this - novice. No one is using the server while the backup takes place. The server has a number of openVPN connections to other nagios boxes as it is a distributed monitoring system so the central server is continuously communicating with the other servers.

So is something holding something open like the vpn's that means the backup is failing. Can i suspend the vm while the backup starts and then enable it once it finishes.

Thanks Dietmar

pls post the output of 'pveversion -v'

Well, 'suspend' is the thing that does not work. But you can use 'stop' or 'snapshot' mode instead.

OK Will try Stop mode as suspend or snapshot is not working. Stop mode might cause a few more alerts mind!! Maybe I can scheduled downtime for the main server? Will let u know.

Thanks

go for the latest stable, you use an old kernel.

Hi forum - still got errors even though I have the latest kernel, etc. Please refer to logs can anyone provide any pointers. Can I exclude vz machine directory from the backup? It seems the stuff in spool is causing an issue.

The problem seems to be the ntpd - I would disable that inside the container(runs on the hots anyways).
