[lxc-users] Howto save snapshots only to another drive? Bug?

[Jäkel, Guido]

Dear Oliver,

I just want to mention, that with this workaround it isn't a real snapshot anymore but may be called a "slow bullet" instead: It will take some real time to copy the whole image and in contrast to a snapshot, it will be not completely consistent if the Container is running at this time.

With greetings

Guido

If it's dir, you could probably work around that by using bind mounts.
something like

rm /path/to/pool/dir/containers-snapshots <= remove the symlink first mkdir /path/to/pool/dir/containers-snapshots <= recreate the directory mount --bind /path/to/new/disk/containers-snapshots
/path/to/pool/dir/containers-snapshots

then test it, see whether new directories/files appear on /path/to/new/disk/containers-snapshots

Not sure whether this is a supported method or not though.
