Backup mal einfach

19:53

Friday, May 19. 2006

Automatisiertes inkrementelles Backup in mehreren Generationen war mir bis her zu aufwaendig, aber dank strcat habe ich rsnapshot entdeckt.

rsnapshot is a filesystem snapshot utility for making backups of local and remote systems.
Using rsync and hard links, it is possible to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals.
Depending on your configuration, it is quite possible to set up in just a few minutes. Files can be restored by the users who own them, without the root user getting involved.
There are no tapes to change, so once it's set up, you may never need to think about it again.
rsnapshot is written entirely in Perl. It should work on any reasonably modern UNIX compatible OS, including: Debian, Redhat, Fedora, SuSE, Gentoo, Slackware, FreeBSD, OpenBSD, NetBSD, Solaris, Mac OS X, and even IRIX.

Bisheriges Ergebniss: Laesst sich schnell installieren, die Konfigurationsdatei is uebersichtlich und selbsterklaerend und es haellt was es verspricht. So sieht das ganze bei mir aus:

  • USB-Festplatte anschliessen und mounten
  • "rsnapshot daily" ausfuehren
  • Kaffee trinken gehen (je nach Groesse des Dateisystems dauert es ein bisschen)
  • freuen, dass die Daten gesichert sind

Da ich nicht jeden Tag Backup anlege und die Platte ebenfalls nicht die ganze Zeit angeschlossen ist, lohnt es sich nicht das ganze zu automatisieren. Man kann das ganze natuerlich auch mit cron und eigenen Scripten steuern.
Alles in allem eine gute Loesung fuer Backups der eigenen PCs.
