How I can make a regular backup ?

make a copy of data.fs _before_ it gets corrupted.

How I can restore it ?

copy your backed up data.fs over your corrupted data.fs

it's 100% corrupted.

I doubt that very much.

...

Do you have any tools for analyse a data.fs ? (not tranalyser)

Why not tranalyser? What about lib/python/ZODB/fsrecover.py which Jim Fulton recommended?

If I don't fint out why my data.fs is corrupted, I'll lost one week of work for my company.

No skin off our noses... a lot of people have tried to help on this _for free_ but you don't seem prepared to do much work for yourself. Your data.fs is corrupted. That sux. Sorry. It doesn't happen often so it'll probably be a bitch to fix, maybe you should just re-import your 900 files into a new data.fs on a fresh install of Zope? Maybe take Jim Fulton up on his offer to look at the data.fs? You might also like to read the Zope manuals: http://www.zope.org/Documentation It may be old and a bit out fo date but it'll give you a good idea of a lto of Zope stuff. Also search on Zope.org. There's good How-To's on recovering corrupted data.fs's... There's also mailing list archives at: http://zope.nipltd.com/public/lists.html Search there and you'll find answers to most questions you've asked: -LoadSite -How to make a backup and restore it -more on Tranilyser and the like Please try these first, the mailing list should be a last resort (and yes, I know I sometimes don't use it as such ;-) cheers, Chris PS: Apologies to the list for the flame, maybe I shouldn't write email at midnight ;-)
