# NAME

bup - Backup program using rolling checksums and git file formats

# SYNOPSIS

bup [global options...] \<command> [options...]

# DESCRIPTION

`bup` is a program for making backups of your files using the git file format.

Unlike `git`(1) itself, bup is optimized for handling huge data sets including individual very large files (such a virtual machine images). However, once a backup set is created, it can still be accessed using git tools.

The individual bup subcommands appear in their own man pages.

# GLOBAL OPTIONS

--version
  print bup's version number. Equivalent to `bup-version`(1)
-d, --bup-dir=BUP_DIR
  use the given BUP_DIR parameter as the bup repository location, instead of reading it from the $BUP_DIR environment variable or using the default `~/.bup` location.
