NAME

       btrfs-send - send data of subvolume(s) to stdout/file.

SYNOPSIS

       btrfs send [-ve] [-p <parent>] [-c <clone-src>] [-f <outfile>] <subvol> [<subvol>...]

DESCRIPTION

       Sends the subvolume(s) specified by <subvol> to stdout.

       By default, this will send the whole subvolume. To do an incremental send, use -p
       <parent>.

       If you want to allow btrfs to clone from any additional local snapshots, use -c
       <clone-src> (multiple times where applicable).

       You must not specify clone sources unless you guarantee that these snapshots are exactly
       in the same state on both sides, the sender and the receiver.

       It is allowed to omit the -p <parent> option when -c <clone-src> options are given, in
       which case btrfs send will determine a suitable parent among the clone sources itself.

       Options

       -v
           Enable verbose debug output. Each occurrence of this option increases the verbose
           level more.

       -e
           If sending multiple subvols at once, use the new format and omit the <end cmd> between
           the subvols.

       -p <parent>
           Send an incremental stream from <parent> to <subvol>.

       -c <clone-src>
           Use this snapshot as a clone source for an incremental send (multiple allowed).

       -f <outfile>
           Output is normally written to stdout. To write to a file, use this option. An
           alternative would be to use pipes.

       --no-data
           Send in NO_FILE_DATA mode. The output stream does not contain any file data and thus
           cannot be used to transfer changes. This mode is faster and useful to show the
           differences in metadata.

EXIT STATUS

       btrfs send returns a zero exit status if it succeeds. Non zero is returned in case of
       failure.
