Hi.

Is there an backup option to vzmigrate. I ideally would like to use vzmigrate on a running container to back it up to another host node.

Vzmigrate looks to be a good tool to do this as I could do

vzmigrate -r no --keep-dst --online -t

But what i really need is a fine switch to say dont actually do the migration swap stage at the end.

Is there a way to do that - could it be enhanced to have that as a flag?

Thanks

Mark

Hi Mark,

I miss that feature as well! That combined with NOT having to use a
passwordless root ssh-certificate (whats wrong with providing ssh/rsync
the password via a prompt?) would be great! Currently I use vzdump and
vzrestore for that purpose of cloning to a different machine - beware
that the target machine should not have the VPSID of the source.

Greetings,
Joe

Just do a rsync of the private area, followed by vzctl chkpnt VEID
--suspend, followed by another rsync and then vzctl chkpnt VEID
--resume, thats what the vzmigrate is doing anyway. Don't forget to copy
over veid.conf, too.

wiki has a good page how it all woerks at
