You really want more RAM! It is pretty cheap nowadays. I've got a quad-core Xeon 1.6 GHz which backs up 24 servers. The pool is about 440 GB, total backup volume is about 4.1 TB (271 full, 200 incr backups), all bacukps are using rsync. The server used to have only 2 GB of RAM and although it did not swap, it was pretty slow and hardly managed to back up half of the servers each night. Since I added another 4 GB, it manages to backup almost all of the servers each night. Largest backup is 120 GB consisting of over 2.2 million files. > I use backuppc backupservers for different small networks and I am > pretty happy with it, but I have the impression that it is a lot > slower then for example bacula.

Bacula doesn't have a pool with lots of files and directories and AFAIK does not use rsync, which requires more RAM and CPU than plain copying. With Linux, additional RAM will be used as disk cache which is very valuable with the filesystem usage pattern of BackupPC. Hope that helps, Tino. -- "What we nourish flourishes." - "Was wir nähren erblüht." www.lichtkreis-chemnitz.de www.craniosacralzentrum.de ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ BackupPC-users mailing list [email protected] List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
