And this is the reason why I have the LVM snapshots. I can go back 5 weeks with the snapshots. That's enough to prevent any serious issues. When the file system gets unreadable I usually notice it immediately- and roll back to previous snapshot.
BTW: The same would happen with the often so proposed "take off a disk of your RAID1". In some way you have to trust the filesystem. Of course rsync'ing it from host A with ext3 to host B with XFS would be a better solution security wise. But as you know rsync is not the best solution here. I trust my file system at least for 5 weeks ;) Greetings Christian ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
