Hi,
I'll be running 1 VPS on each server normally.
I'd like to be able to replicate each VPS to its backup server(s). For
example:
• SERVER1 = VPS1 (VPS2's backup server)
• SERVER2 = VPS2 (VPS1's backup server)
I thought to user a modified vzmigrate script for mantain a copy of
VPS2 (in the case of SERVER 1). If SERVER 2 fails, i can get up the
VPS 2 quickly.
What modifications should i do in the vzmigrate?
If I understand you correctly, you'd basically like to backup a container's
filesystem and config to a separate host node periodically so in case of a
hardware failure, you could start up the container on the other host.
My question to you is how often do you want the backup to be done or another way of putting it is... how close does the backup have to be to the original in case of a failure?
I sync every hour.
If you are trying to make a sort of High Availability setup where the original
and the backup are in sync as much as possible, I'd recommend you check out
some of the HA related wiki pages.
HA it's more complex for me.
If a once-a-day backup is all you are looking for, I'd recommend creating a
simple script that does an rsync of the container's filesystem and config while
it runs and then does a shutdown and a second rsync and starts it back up.
I can't stop the containers of my clients.
vzdump is also something you'd probably want to look at as it'll give you some
more options.
The backups are aprox of 100GB and is more slow manage the backups and
restores with vzdump.
¿Maybe with vzctl chkpnt?
As you can imagine there is a broad range of backup scenarios, and what you'd
want to do would vary.
TYL,
