zfs snapshotting and backups in lxc container?

[kyriazis]

Hello,

I am planning on using sanoid/syncoid or something similar to perform snapshots and backups of my zfs pool(s).

I understand that I can add packages and/or do whatever I need in the host debian environment, but I was wondering if I can do the same inside an lxc container with the host zfs pools mounted with mpX: in the conf files. My reasoning is that I don't want to pollute the host environment (I want to keep things compartmentalized)z, and also taking backups of containers is much easier than backing up specific setups on the host.

Any thoughts?

Thank you!

George

I don't think that will work. ZFS snapshots are deeply buildin into the filesystem itself working on block level and you can only create them running the zfs command on your host. If you bind-mount a mountpoint of a dataset into a LXC that is all done on the file level.

Yes, that's my understanding, too. I am just hoping that someone may have some piece of knowledge that I don't.
