So this is exactly the same than what I do incremental backups with brrfs send, but -p only works if the snapshot is read only, does it not? I do use that for my incremental syncs and don't mind read only snapshots there, but if I have read/write snapshots that are there for other reasons than btrfs send incrementals, can I still send them that way with -p? (I thought that wouldn't work) Thanks, Marc -- "A mouse is a device used to point at the xterm you want to type in" - A.S.R.
