BTRFS−RECEIVE

NAME

btrfs-receive − receive subvolumes from stdin/file.

btrfs receive [−ve] [−f <infile>] [−−max−errors <N>] <mount>

Receives one or more subvolumes that were previously sent with btrfs send. The received subvolumes are stored into <mount>.

btrfs receive will fail with the following case:

1. a receiving subvolume already exists.

2. a previously received subvolume was changed after it was received.

3. default subvolume is changed or you don’t mount btrfs filesystem with fs tree.

After receiving a subvolume, it is immediately set to read only.

Options

−v

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

−f <infile>

By default, btrfs receive uses stdin to receive the subvolumes. Use this option to specify a file to use instead.

−e

Terminate after receiving an <end cmd> in the data stream. Without this option, the receiver terminates only if an error is recognized or on EOF.

−−max−errors <N>

Terminate as soon as N errors happened while processing commands from the send stream. Default value is 1. A value of 0 means no limit.

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