[Zope] Maintaining Zope/ preventing Data.fs corruption

[Scott Syms]

Hi, folks-

I've recently lost a wiki site because of what looked like corruption in the
data.fs file. So I'm wondering if there are any "grooming" tools out there
that can report on the integrity of the Zope db and/or fix problems in the
file before it bites the dust.

How stable are the alternative storage engines for Zope, ie/ storing data in
Oracle, etc?  And is there an upper limit on how much data I can store in
the Data.fs safely?

much appreciated

tks
