Re: [rdiff-backup-users] rdiff-backup Input/output error

[Thomas S. Dixon]

Thank you very much for the reply. You were absolutely right, the 
problem was a lower-level filesystem problem. I had a corrupted 
partition somehow. Once i recreated and reformatted the partition, 
restored the rdiffs from tape again, it worked like a charm.
