BORG-EXTRACT(1) borg backup tool BORG-EXTRACT(1)

NAME

borg-extract - Extract archive contents

SYNOPSIS

borg [common options] extract [options] ARCHIVE [PATH...]

DESCRIPTION

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 PATHs as arguments. The file selection can further be restricted by using the --exclude option.

See the output of the "borg help patterns" command for more help on exclude patterns.

By using --dry-run, 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.

--progress can be slower than no progress display, since it makes one additional pass over the archive metadata.

NOTE:

Currently, extract always writes into the current working directory ("."), so make sure you cd to the right place before calling borg extract.

EXAMPLES

# Extract entire archive
$ borg extract /path/to/repo::my-files
# Extract entire archive and list files while processing
$ borg extract --list /path/to/repo::my-files
# Verify whether an archive could be successfully extracted, but do not write files to disk
$ borg extract --dry-run /path/to/repo::my-files
# Extract the "src" directory
$ borg extract /path/to/repo::my-files home/USERNAME/src
# Extract the "src" directory but exclude object files
$ borg extract /path/to/repo::my-files home/USERNAME/src --exclude '*.o'
