I run an docker compose project inside an lxc container on btrfs storage.
The general workflow works well (lxd snapshot) but export/copy didn’t
docker creates lot of subvolumes which mostly identical content.
Inside the container:
btrfs filesys du / -s 2>/dev/null Total Exclusive Set shared Filename 41.28GiB 29.26MiB 12.74GiB /
But if I export the lxc container, the archive is hugh.
--instance-only --optimized-storage is ~30 GB.
Did anyone know a good solution/workaround?
