Excellent info... thanks.  

It seems there should be some safeguard in place to prevent a change
like this from allowing rsnapshot to eat its previously created
backups.

After installing the new cp, rsnapshot ate one full hourly.* every 4
hours until only hourly.0 remains by rming hourly.5 and moving
hourly.* to hourly.5.  And of course it won't copy hourly.0 to
hourly.1 so hourly.0 isn't even renewed either.  Within a few hours
your relied upon backups have chewed themselves into oblivion.

I've scripted something that writes a .SUCCESS file to my rsnapshot
base each run so if it isn't found right before running rsnapshot,
then rsnapshot isn't run.

I'm surprised there wasn't some similar safeguard built into
rsnapshot.
