Shutdown the container # lxc-stop -n $NAME Archive container rootfs & config # cd /var/lib/lxc/$NAME/ # tar --numeric-owner -czvf container_fs.tar.gz ./* Is there a higher analog of "category with all same side inverses is a groupoid"? First cd into your lxc container root directory: cd /var/ lib /lxc/ debian8 /rootfs/ (If you used an lvm volume as your containers storage, you need to mount it and cd into your mount point, which can be done by mount /dev/mapper/<lvgroup-lvdisk> /var/lib/lxc/debian8/rootfs/, and than cd into the mount point) Create an archive: Find centralized, trusted content and collaborate around the technologies you use most. Stop the container & create a tar.xz archive of it. Connect and share knowledge within a single location that is structured and easy to search. File and image backups are made while the system is running without interrupting current processes. Please support me on Patreon: https://www.patreon.com/roelvandepaarWi. btrfs su create /mnt/largepool/lxd/containers/c1 To sign Duply backups see GnuPG in Automated Environments ( password-less signing key instead of storing the password in plaintext ). Replace the content of the lxd container's rootfs with the content of the lxc container's rootfs. Then install and configure all components that you need, save it as a snapshot, and create an image from the said snapshot. @LawrenceCherone Well actually my intentions are to move the container to another host with higher cpu/ram resources when the load is heavy on it and once the load decreases to move it back to the old server where it can run on a proper load. To just backup containers edit ~/.duply/mybackup/conf & change SOURCE='/' to SOURCE='/var/lib/lxc' & remove the non lxc lines from ~/.duply/mybackup/exclude.

Tested with running Alpine Linux LXC containers - will also work on Debian. The big problem with LXD is that (currently) it only seems to support just one storage pool. To learn more, see our tips on writing great answers. A better, somehow built-in way, of transfering data from host to lxc-container is line #4 in below code: 1 $ mkdir /tmp/transferDir 2 $ cp <some files> /tmp/transferDir/<some files> 3 $ cd /tmp 4 $ tar -C transferDir -c .
