How to backup VMs when low on storage space?

[BigTimer]

Hello,

I'm practically out of disk space on a Proxmox 2.x installation and I'm trying to backup the VMs on it onto a remote server. I attached a partition on the remote server to the Proxmox server with sshfs.

But everytime I run vzdump I get the message:

vbed2:~# vzdump 102 -dumpdir remote-drive/INFO: starting new backup job: vzdump 102 --dumpdir remote-drive/
INFO: Starting Backup of VM 102 (qemu)
INFO: status = stopped
INFO: backup mode: stop
INFO: ionice priority: 7
INFO: creating archive 'remote-drive/vzdump-qemu-102-2015_02_01-19_15_29.vma'
INFO: starting kvm to execute backup task

INFO: aborting backup job

INFO: Backup job finished with errors

This applies to all VMs on the server. I've checked online and saw a similar situation mentioned in the mailing list (http://pve.proxmox.com/pipermail/pve-user/2013-September/006129.html), but no solution was actually offered.

Could I have some suggestions on how to get these VMs backed-up or migrated to another server please? Thank you.

Find there vzdump copies files (makes archive) and mount that point with sshfs. Try to look to /tmp

Thanks for the reply Nemesiz, but I really don't understand what you mean?

Store temporary files to specified directory.

Maybe it will help you
