=============

|
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.
