Here the descritpion of the problem:
The daily updatedb-job crashes, when the filesystem becomes too large. If this depends on the number of files or size of all files i don't know. The BackuPC-Pool becomes very soon very huge (in my case about 250GB with al huge number of files).

As there is no real advantage in taking the BackupPC-Pool-Files in the updatedb i think a solution would be to add '/var/lib/backuppc' to PRUNEPATHS in /etc/updatedb.mlocate.

It' quite likely, that updatedb would crash with other Filessystems which become huge as well but i don't know.

This is all what i can add to this case, if it is not enough i appologize.

Correct path is:
mlocate: /etc/updatedb.conf

Marking backuppc task Invalid and raising an mlocate bug task.

Thanks.
