You mean the rdiff-backup version? It's 1.2.8 on both servers. But does
it to an in-place comparison? If I understand the man page correctly, it
first copies the data from the dest to the source and then compares it

I definitely care about more than just the most recent backup. I need to
be able to restore from prevous days, weeks, and months, which was the
whole point of using rdiff-backup in the first place. But I can
understand using the most recent backup as a benchmark for testing the
backup quality.

That could work, too. Thanks for the suggestion.

I'd still rather just use something built into rdiff-backup if possible.
