Hi,

I've got an boxbackup server which crashed a few days ago; now I'm  
trying to resume backups. As the link is quite slow I'd rather reuse  
the data that's already on the server. However, I'm unable to fix one  
of the accounts with bbstoreaccounts. It's the second time I run into  
this error, so I thought it would be worth asking...
Permissions seem correct to mee (everything owned by bbstored:bbstored).

Do you have any hints? I've tried to compile a debug version and find  
the error using it, but I've got an "assertation failed" error there.

Thanx a lot,
Baltasar

You should now use bbackupquery on the client machine to examine the  
store.
