[Duplicity-talk] backup failures : CRC error

[Bonvicini, Alessandro]

Hi all,
just this morning I discovered this error on my backup logs.
What does it means?
What kind of operation  need to be done? Perhaps delete the last day inc
set?

Please help to understand the error ,   I would be sure that my backup
set is functional.
Thank a lot in advance
Alex
