hdup

The little, spiffy, backup tool
If its not backed up, its gone!

Unmaintained! I'm using rdup nowadays. But hdup is a mature/stable program, so be free to use it

hdup in rdup

I've tried to write up why I think rdup is a better tool; I can rewrite hdup in rdup, see: this blog post

what is it?

Hdup2 is a backup utilty, it's aim is to make backup really simple. The backup scheduling is done by means of a cronjob. Is supports a include/exclude mechanism, remote backups, encrypted backups and split backups (called chunks) to allow easy burning to CD/DVD.

features

simple to use,
small and versatile backup program,
support for incremental backups,
support for backups over the network (with ssh),
support for network restore (with ssh),
support for encrypted backups (using mcrypt, gnupg),
support for split up archives (called chunks),
support for .nobackup files (to exclude certain directories),
flexible regular expression based include/exclude mechanism,
designed to be run from cron.
You need a Gnu tar version > 1.3.25

Hdup should run and compile on all Unixes out there. It does depend on Gnu tar for the backups. It also needs glib-dev if you compile it yourself. Also for building it you need Gnu Make.

You'll also need a recent tar version. Anything after 1.3.25 should work. Newer is better.

Backups

The scheme implemented by hdup2 is sometimes called the Grandfather-Father-Son scheme, Hdup just calls it: monthly-weekly-daily. Using this scheme it is wise to keep your backups for a minimum of one month.

release 2.0.14

Version: 2.0.14 (released 10 December 2005)

This is a bug fix release.

Split up hdup in hdup-dump and hdup-restore?
i18n for hdup's output?
