# 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.
# COMMONLY USED SUBCOMMANDS
`bup-fsck`(1)
: Check backup sets for damage and add redundancy information
`bup-ftp`(1)
: Browse backup sets using an ftp-like client
`bup-fuse`(1)
: Mount your backup sets as a filesystem
`bup-help`(1)
: Print detailed help for the given command
`bup-index`(1)
: Create or display the index of files to back up
`bup-on`(1)
: Backup a remote machine to the local one
`bup-restore`(1)
: Extract files from a backup set
`bup-save`(1)
: Save files into a backup set (note: run "bup index" first)
`bup-web`(1)
: Launch a web server to examine backup sets
# RARELY USED SUBCOMMANDS
`bup-damage`(1)
: Deliberately destroy data
`bup-drecurse`(1)
: Recursively list files in your filesystem
`bup-init`(1)
: Initialize a bup repository
`bup-join`(1)
: Retrieve a file backed up using `bup-split`(1)
`bup-ls`(1)
: Browse the files in your backup sets
`bup-margin`(1)
: Determine how close your bup repository is to armageddon
`bup-memtest`(1)
: Test bup memory usage statistics
`bup-midx`(1)
: Index objects to speed up future backups
`bup-newliner`(1)
: Make sure progress messages don't overlap with output
`bup-random`(1)
: Generate a stream of random output
`bup-server`(1)
: The server side of the bup client-server relationship
`bup-split`(1)
: Split a single file into its own backup set
`bup-tick`(1)
: Wait for up to one second.
`bup-version`(1)
: Report the version number of your copy of bup.
# ENVIRONMENT
`BUP_ASSUME_GIT_VERSION_IS_FINE`
: If set to `true`, `yes`, or `1`, assume the version of `git`
in the path is acceptable.
# SEE ALSO
`git`(1) and the *README* file from the bup distribution.
The home of bup is at <http://github.com/bup/bup/>.
