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 PATH arguments. The default interpretation for the paths to extract is pp: which is a literal path-prefix match. If you want to use e.g. a wildcard, you must select a different pattern style such as sh: or fm:. See borg_patterns for more information.

The file selection can be further restricted by using the --exclude option. For more help on include/exclude patterns, see the borg_patterns command output.

By using --dry-run, you can do all extraction steps except actually writing the output data: reading metadata and data chunks from the repository, checking the hash/HMAC, decrypting, and 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.

When parent directories are not extracted (because of using file/directory selection or any other reason), Borg cannot restore parent directories' metadata, e.g., owner, group, permissions, etc.

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'
    # Extract only the C files
    $ borg extract /path/to/repo::my-files 'sh:home/USERNAME/src/*.c'
    # Restore a raw device (must not be active/in use/mounted at that time)
    $ borg extract --stdout /path/to/repo::my-sdx | dd of=/dev/sdx bs=10M
