.TH "BORG-EXTRACT" 1 "2024-02-20" "" "borg backup tool"
.SH NAME
borg-extract \- Extract archive contents
.SH SYNOPSIS
.sp
borg [common options] extract [options] NAME [PATH...]
.SH DESCRIPTION
.sp
This command extracts the contents of an archive. By default the entire
archive is extracted but a subset of files and directories can be selected
by passing a list of \fBPATHs\fP as arguments. The file selection can further
be restricted by using the \fB\-\-exclude\fP option.
.sp
For more help on include/exclude patterns, see the \fIborg_patterns\fP command output.
.sp
By using \fB\-\-dry\-run\fP, you can do all extraction steps except actually writing the
output data: reading metadata and data chunks from the repo, checking the hash/hmac,
decrypting, decompressing.
.sp
\fB\-\-progress\fP can be slower than no progress display, since it makes one additional
pass over the archive metadata.
.sp
\fBNOTE:\fP
.INDENT 0.0
.INDENT 3.5
Currently, extract always writes into the current working directory (\(dq.\(dq),
so make sure you \fBcd\fP to the right place before calling \fBborg extract\fP\&.
.sp
When parent directories are not extracted (because of using file/directory selection
or any other reason), borg can not restore parent directories\(aq metadata, e.g. owner,
group, permission, etc.
