Hi Johan, First thank you so much for your efford, although is hasn't solved the problem yet.
Unfortunally I don't that much extra space to accommodate an extra copy of the backups. (around 6TB). I have been thinking it looks like none of the BackupPC utility programs (BackupPC_xxxx) are working, so there must be a common denominator. I wonder how do these programs find the backups - for tarCreate for instance you nowhere give a path to the backups - so how does this work? I'm looking forward to hear from anybody with a clue to fix this problem!
