I dont know, if this could be the problem.



We had, some 4-5 years ago when we first started to use Firebird, a customer where it became corrupted all the time.



At last we found out, that a tape backup rutine was running sometimes and doing a copy of the Firebird DB.

This is not good J



We then excluded the Firebird DB and only took backup of the Firebird GBAK file.

Emne: Re: [firebird-support] Repeated database corruption








Today the database EMPRESAP got corrupted for the 5th time.

I will update the version of FireBird as Gabros suggested.

Any other ideas of what may be causing this repeated database corruption?

I post what firebird.log says.

Hi,

I don't know the answer for the whole question but...

I found this things for you:
http://tracker.firebirdsql.org/browse/CORE-973
http://tracker.firebirdsql.org/browse/CORE-1961

If you use 2.0.x why not the latest 2.0.5?
