Welcome to the list.

That action is used for the same thing on the master as on the other
peer nodes - to collect the data that's later staged and stored.  This
is why you would normally list the master as one of the local peers in the
staging section.

Yeah, it's sometimes a struggle to get useful information into the log.
In this case, I'm trying to capture output from the command to be parsed
later, but to do that, I need to discard stderr.  That makes it
difficult to get useful diagnostic information from the command when it
returns a non-zero status.  You could try running Cedar Backup with the
--debug flag and see if that gives you any other useful information (it
might).   At the least, you'll see exactly what command was run.

Thanks.  If you do reproduce it manually, let me know what caused it and
I'll try to fix it.  There's just not much that should go wrong with
svnlook, unfortunately. :(

I get back "You are not allowed to view this page", even after creating
a user and logging in.

Certainly. 

I keep 7-10 days of staging directories around, but switch media mostly
every week.  That way, I can periodically take a disc off-site in case
the machine gets stolen or damaged.  If you're not worried about these
risks, then there's no need to write to disc.
