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

NAME

borg-extract - Extract archive contents

SYNOPSIS

borg [common options] extract [options] NAME [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.

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