Simple script to backup LXC containers

lxc-backup.sh

#!/usr/bin/env bash
set -ex

BACKUP_DIR=/path/to/where/backups/should/live
HOSTS=($(lxc list -c n --format csv))

for HOST in "${HOSTS[@]}"
do
    BACKUP_NAME=${HOST}-$(date +"%Y-%m-%d")

    lxc snapshot ${HOST} auto-backup
    lxc publish ${HOST}/auto-backup --alias ${BACKUP_NAME}
    lxc image export ${BACKUP_NAME} ${BACKUP_DIR}/${BACKUP_NAME}
    lxc image delete ${BACKUP_NAME}
    lxc delete ${HOST}/auto-backup
done

Awesome :)

One question though.. Will this also re add devices back to the container's config that you've added with:
lxc config device add c1 sharedwww disk source=/wwwdata/ path=/var/www/html/
