[Zope] Looking to increase confidence in my Backups

Ho there,

I've got a backup strategy that seems to be working fine for me, but  
I'm ever looking for ways to increase confidence that the backups I'm  
making of Data.fs are actually functional and can be restored from  

To that end, I was reading some info on this page:


and playing with the fstest and fsrefs scripts referenced there.   
I've discovered a problem (I think).  Here's the scenario:

$ python fstest.py -v Data.fs
Traceback (most recent call last):
   File "fstest.py", line 228, in <module>    main()
   File "fstest.py", line 215, in main
UnboundLocalError: local variable 'VERBOSE' referenced before assignment

The same error arises in using fsrefs, although there the line where  
the error is raised reads
     VERBOSE += 1

By changing the declaration of VERBOSE from

   VERBOSE = 0


   VERBOSE = 1

the error goes away, but of course you always get verbose output,  
which we don't really need or want for automated integrity checks, do  

Am I using the right tool for this job?  Is there a better way out  
there to create automated integrity checks of Data.fs files restored  
from repozo-generated backups?
