RE: [rdiff-backup-users] Crash in 1.3.3

[Craig Findlay]

Hi Josh,

Yes, it could be flaky hardware, in particular it could be the
destination drive, which is a very well known brand of USB external
drive that seem in my experience to fail quite often. But I can do a
successful backup of the same data to the same destination drive using
rsync, with no problem. Any thoughts on this? The rest of the hardware I
trust because it is a server we use all the time for other critical
tasks.

Cheers,
Craig

CRC check failures typically indicate faulty or dying hardware.
