This makes backup easy: I simply mount the root subvolume which contains everything under /mnt/btrfs-root and backup this. This automatically excludes the various runtime mounts like /proc or tmpfs, or net mounts. Plus, it preserves the static /dev delivered by the rootfs deployment of your distribution (and also the various .keep files for important mount points). Before backup, I also dump the subvolume list to a text file. You can get something different by bind-mounting your volumes into a directory especially for crafting the backup. Just make /mnt/system-backup and bind mount / and /home there (and other system parts you exported to separate partitions). That way, runtime and network mounts are not visible there and you get a perfect and clean backup without the hassle of creating a pile of unmaintainable and always incomplete (and maybe even error-prone) exclude lists. Then, maybe dump your mounttab or fstab to the backup root before starting the backup process. That way, you can more easily recreate your partitions before you restore, and get back a working fstab without too much thinking. -- Regards, Kai Replies to list-only preferred.
