This is exactly what I was thinking about. Hm. In normal state , XFS
is the best filesystem I know (speed, reliability). In the case of
hardware/power failures , this is another story; however, these are
very very rare events, perhaps one or two max per year, and they do
not cause so much damage. So, XFS is still the best choice for us, I
hope.
By the way, backups are always goods...This saved a lot of my users
work.

Actually, this is our UPS which failed...
Thanks for your reply.
