The received subvolumes are stored to +\fIpath\fP, unless \fI\-\-dump\fP option is given. +.sp +If \fI\-\-dump\fP option is specified, \fBbtrfs receive\fP will only do the validation of +the stream, and print the stream metadata, one operation per line. +.sp +\fBbtrfs receive\fP will fail in the following cases: +.INDENT 0.0 +.IP 1. 3 +receiving subvolume already exists +.IP 2. 3 +previously received subvolume has been changed after it was received +.IP 3. 3 +default subvolume has changed or you didn\(aqt mount the filesystem at the toplevel subvolume +.UNINDENT +.sp +A subvolume is made read\-only after the receiving process finishes successfully (see BUGS below). +.sp +\fBOptions\fP +.INDENT 0.0 +.TP +.BI \-f \ <FILE> +read the stream from \fIFILE\fP instead of stdin, +.UNINDENT +.INDENT 0.0 +.TP +.B \-C|\-\-chroot +confine the process to \fIpath\fP using \fBchroot(1)\fP +.UNINDENT +.INDENT 0.0 +.TP +.B \-e +terminate after receiving an \fIend cmd\fP marker in the stream. +.sp +Without this option the receiver side terminates only in case +of an error on end of file. +.UNINDENT +.INDENT 0.0 +.TP +.B \-E|\-\-max\-errors <NERR> +terminate as soon as NERR errors occur while stream processing commands from +the stream +.sp +Default value is 1.

However, while the receive is in progress, users who have +write access to files or directories in the receiving \fIpath\fP can add, +remove, or modify files, in which case the resulting read\-only subvolume +will not be an exact copy of the sent subvolume. +.sp +If the intention is to create an exact copy, the receiving \fIpath\fP +should be protected from access by users until the receive operation +has completed and the subvolume is set to read\-only. +.sp +Additionally, receive does not currently do a very good job of validating +that an incremental send stream actually makes sense, and it is thus +possible for a specially crafted send stream to create a subvolume with +reflinks to arbitrary files in the same filesystem. Because of this, +users are advised to not use \fIbtrfs receive\fP on send streams from +untrusted sources, and to protect trusted streams when sending them +across untrusted networks. +.SH EXIT STATUS +.sp +\fBbtrfs receive\fP returns a zero exit status if it succeeds. Non zero is +returned in case of failure. +.SH AVAILABILITY +.sp +\fBbtrfs\fP is part of btrfs\-progs. Please refer to the documentation at +\fI\%https://btrfs.readthedocs.io\fP or wiki \fI\%http://btrfs.wiki.kernel.org\fP for further +information. +.SH SEE ALSO +.sp +\fI\%btrfs\-send(8)\fP, +\fI\%mkfs.btrfs(8)\fP +.\" Generated by docutils manpage writer. +. |
