## ccollect - (pseudo) incremental backup with different exclude lists using hardlinks and rsync

<P ALIGN="center">

</a>
<P>ccollect backups data from local and remote hosts to your local harddisk.
Although ccollect creates full backups, it requires very less space on the
backup medium, because ccollect uses hardlinks to create an initial copy of
the last backup. Only the inodes used by the hardlinks and the changed files
need additional space.

ccollect uses [rsync](http://www.samba.org/rsync/) for synchronisation.
Since ccollect-0.2 there is [asciidoc](http://www.methods.co.nz/asciidoc/)
based documentation included in the distribution (see below).
You should also be able to configure ccollect with the help of the example
configuration in conf/.

### Portability
As ccollect is a simple shell script, it should run on
any POSIX compatible OS. It is known or reported to run on:

 * FreeBSD:   amd64/i386
 * Linux:     alpha/hppa/ppc/i386
 * NetBSD:    alpha/sparc64/i386/amd64
 * OpenBSD:   amd64

Feel free to send an e-mail if you are running ccollect on
another OS or architecture.

For more information regarding portability have a look at the [[u2u|net/u2u]] idea.

### Sample configurations
 * <a href="config/ccollect-buche-2006-06-16.tar.bz2">Configuration
   for ccollect 0.4 or later from buche.intern.schottelius.org</a>
 * <a href="config/ccollect-eiche-2006-02-05.tar.bz2">Configuration
   for ccollect 0.3.3 or earlier from eiche.intern.schottelius.org</a>

    Hallo,

    auf der Suche nach einer Lösung für meine Backups (Debian/amd64) bin ich auf ccollect gestoßen.
    Ist wirklich ein tolles Skript / System und mein Favorit. [...]

    thx for an uncomplicated, easy and straightforward backup solution.

    Hi Nico,
    first of all: congratulation for ccollect, a really lovely script!

    i've tried a lot of backup solution (veritas netbackup, rsnapshot, bacula)
    but no other software is so simple and effective.
    ccollect resolves 93% of backup problems in few minutes with standard tools.

Benedikt Köppel

    Hi Nico,
    
    thank you very much for your great software ccollect. I just started
    using it to backup my notebook, my server and all computers of my family.

Norbert Titko

    works like charm (just upgraded to 0.7.1)

John Lawless

    Dear Nico Schottelius,

    I have started using ccollect and I very much like its design:
    it is elegant and effective.

Patrick Drolet

    Hello,

    Thank you for making ccollect public; it is a very nice and well written
    utility. I am using it to backup two NAS (DNS323 and QNAP TS-209) across
    the Internet, where bandwidth and upload/download quota is limited.

三宅 兼人 (Kanehito Miyake)

    P.S. Thanks you for offering a nice & pretty backup tools.
         It is very fit in me.

Derek Moore

    Hey, Nico,

    I've used rsnapshot in the past, but recently decided to switch to using
    your ccollect.  I like that it's implemented in sh.

    ccollect is AWESOME & very handy!
