Hi All,
I have question regarding lxd backups. I have a spare server and want a lxd backup server.
What would be the way to go. offcourse i use linux tooling to backup my files. However in a case where my server would die i want to be up and running in minimum of down time.
What are your recommendations? can it be done with a spare lxd server?
kind regards,
Chris
Hi Chris,
Please take a look at this page as it may answer your questions:
Hi Thomas,
I saw this page indeed. What would be your approach to do this? To be able to be online as fast as possible?
Hi!
Try this (https://www.cyberciti.biz/faq/how-to-backup-and-restore-lxd-containers/)
I use this too
lxc export && lxc import
or
lxc snapshot && lxc restore
Else you can take a look at this solution ( But I didn’t use it)

You can also use another LXD server and then use lxc copy <instance> <remote>: --refresh to sync the instance to another server.
Hi Tomp,
When i do it with an backup lxd server. lxc copy instance remote: --refresh
wil it do incremental or copy all data over the network every time?
Can i also do somthing like zfs replication? while the machines are running. with databases and stuff?
The idea of --refresh is that it does incremental copies.
Mostly it uses rsync over the LXD API to do the sync.
But depending on the source/target storage pool types it also supports using the underlying native optimized transfer mechanisms, and these rely on having snapshots (using lxc snapshot <instance>) to transfer the differences from.
See https://github.com/lxc/lxd/pull/11323#discussion_r1094333583 for more info.
ok thanks,
I was thinking. if i do the following will it work?
i want to install a second seperate host with lxd installed. I then want to replicate my zfs torage pools to the second lxd machine.
When my first machine goes offline i then yust start up the lxd machines in the second host.
will this work? or am i thinking the wrong way?
