You're absolutely right. 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 ;)
