Hi everyone,

sorry for bugging again, but as this forum serves great support, I need to ask you once more.
I´m working on a simple backup-system for an OpenVZ HardwareNode. In fact I would like to clone running VEs onto another HardwareNode.
My first choice was vzdump. Unfortunately restoring of rather big VEs takes a lot of time. Thus I would like to use vzmigrate, which supports online-migration with acceptable downtime.
However as I only want the destination VE to be a backup, I need to set it offline, while the source remains online. Is this possible somehow? Just couldn´t find a solution or cheatcode.

Regards

Norman

Have you tried, vzdump with the --suspend option, for backuping the
the container ?

yeah I did, but actually this creates a backup-dump which needs desperate much time to be restored afterwards. Thus I´m looking for a faster way. Backups need up to 10gb...

Hi

You could try suspending, rsyncing, and then resuming:

vzctl chkpnt 103 --suspend
rsync -avH --delete /vz/root/103/ /home/vzbackups/103/
vzctl chkpnt 103 --resume
