btrfs-receive — receive subvolumes from stdin/file.
btrfs receive [options] <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:
- a receiving subvolume already exists.
- a previously received subvolume was changed after it was received.
- 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.
- 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.
- Confine the process to <mount> using chroot.
- 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.
- The root mount point of the destination fs.
By default the mountpoint is searched in /proc/self/mounts. If you do not have /proc, eg. in a chroot environment, use this option to tell us where this filesystem is mounted.
btrfs receive returns a zero exit status if it succeeds. Non zero is returned in case of failure.
