Hmm,
 
That may be it, because the zgrep command turns up SHA1 digests in some of the 
files.  Honestly, I have only been using rdiff-backup for a year, I don’t think 
I had any of the 1.0.x versions but I obviously did.
 
So there IS some SHA1 info….do I have to blow away my whole backup and re-do it 
to get the rest of the files done?

Looks like I’m missing my digest
 
3.)    Yes, run on the mirror side.  I run it like
rdiff-backup –verify /path/to/mirror/ 
Is this correct?  Maybe that’s my problem?  I just couldn’t find any usage 
information.
 
Yes, that syntax is correct.



Do I have to enable the SHA1 digest storage somehow?
 
No, there is no configuration option.
 
 
Thinking about it some more, I think the answer could be simple. Did you 
originally use rdiff-backup 1.0.x ? And have recently upgraded to 1.2.x ? If 
so, then rdiff-backup woul d only be storing SHA1 sums for the new and updated 
files. ACCPACPL.PIF was last modified in the 1990's, so it wouldn't have a SHA1 
sum if it was first backed-up with 1.0.x.
 
If you look in the mirror_metadata file again, do you see any lines that start 
"  SHA1Digest" ... ? eg:
 
$ zgrep SHA1Digest 
/path/to/mirror/rdiff-backup-data/mirror_metadata.*.snapshot.gz
