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.

Subcommands are described in separate man pages. For example bup-init(1) covers bup init.

GLOBAL OPTIONS

--version

print bup’s version number. Equivalent to bup version.

-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.
