Garder un historique à 3 ans de ses documents avec Backuppc

J’utilise Backuppc depuis maintenant plus de 5 ans. Et je dois dire que je l’apprécie énormément… Difficile à mettre en place certes.

Mais quelle liberté ;-) On peut lui faire faire ce que l’on veut. Le prix à payer est une prise en main parfois délicate, surtout pour ceux qui ne sont à l’aise avec le PERL.

Moving Backuppc Data Dir

Tech Recipe for Backuppc


I will explain briefly how to move the Backuppc __TOP_DIR__ to another disk. The main reason of this long data processing is the performance improvement. I’ve tried several Filesystems and different under layer block device ( RAID5, RAID10) alwaysover LVM.

For the moment the best seems to be RAID10 with 32K chunksize and a reiserfs filesystem mounted with (notail,noatime) options.

The backup speed is not that much faster than on ext3 filesystem, but the main advantage of Reiserfs is that compare to ext3 the disk usage is reduced from 34G in ext3 to 27G in Reiserfs.

The next step will be to test Btrfs performance but for that I first need to migrate from kernel 2.6.18 to 2.6.28 or higher ;-)
