Looks like I’m missing my digest
 
3.)    Yes, run on the mirror side.  I run it like

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
