Matthias,

Sorry to hear about that. I would recommend the following:
- Consider all the backed up data corrupt (don't build any new backups on it)
- Start a fresh pool, saving the old one for the duration of your normal cycle
- Look for the reason for the crash/corruption and prevent it from happening
- After that, there's no need to disable nightly

If a full backup is not possible (remote rsync), it may be feasible to 
check the
integrity of the pool (VerifyProb=1 for a while) and manually correct any
problems. But beware, if there are many errors it could take ages.

Hth,
Johan Ehnberg
