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.

For more help on include/exclude patterns, see the borg help 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 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.

When parent directories are not extracted (because of using file/directory selection or any other reason), borg can not restore parent directories’ metadata, e.g. owner, group, permission, 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'

# 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
