Hi list, Is there an advised way to completely “clone” a complete BTRFS filesystem, I mean to get an exact copy of a BTRFS filesystem including subvolumes (even readonly snapshots) and complete file attributes including extended attributes, ACLs and so, to another storage pool, possibly defined with a different RAID geometry or compression ?
The question boils down to getting an exact backup replica of a given BTRFS filesystem that could be restored to something logically absolutely identical. The usual backup tools have no clue about share extents, snapshots and the like, and using btrfs send/receive for individual subvols is a real pain in a BTRFS filesystem that may contain hundreds of snapshots of different BTRFS subvols plus deduplication etc. So on a practical standpoint, how can one backup and restore a full BTRFS structure ? (I know of tools like partclone that may or may not do the job as they usually lack behind recent BTRFS features, and may not be able to clone BTRFS RAID setups for example...)
