Can you browse and restore individual files from snapshots without rolling back the entire container? Through .zfs/snapshot or another way?
I’ve been using samba+vfs_shadow_copy2 (to integrate with VSC on Windows) without LXD. Now I’m trying to move this inside a container, but can’t find any way of getting the .zfs/snapshot directories.
I’m on LXC 3.14. Thanks for any help you can provide!
In theory you could try to expose the magic directory using a disk device, setting the source to the host path for it. But it’s worth remembering that this is a weird magic path, so you may have some pretty odd behavior accessing it.
Also, keep in mind that the uid/gid of files in snapshots may be completely wrong as containers can change maps at times. LXD handles that fine on restores or copies as it knows what the uid/gid map of a given snapshot is and can translate the uid/gid information, but that’s not something you can do on the fly by passing the magic directory through.
Done
I’ve only just discovered this shortcoming with LXD and ZFS snapshots.
Today I noticed a single (hidden) file was missing from one of my LXD containers
“No problem!” I thought “I’ll just mount the dataset then I’ll be able retrieve the file from the .zfs dir”
Nope! All of the .zfs/snapshots subdirs are empty 
Very disappointing. Is this yet another side effect / downside of LXD using snaps under Ubuntu? I wonder if this works OK with LXD under Debian or any other OS not blighted by snaps?
Please fix this if you can. Can you tell I DO NOT like snap packages?
