BTRFS-SEND(8) Btrfs Manual BTRFS-SEND(8)NAMEbtrfs-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.
EXIT STATUS
btrfs send returns a zero exist status if it succeeds. Non zero is
returned in case of failure.
