Resolution: No Available Fix
The backup pages does not offer best practices for interval, storage, and retention policies for Puppet Backups.
Current text :
Customizing backup and restore scope section.
Add a paragraph with the suggested best practices with an example. This section says you should backup based on quantifiable examples like 10 code base and 1,000 nodes checking in hourly, we recommend the following: backups should be scheduled 1x daily for PuppetDB, while the code base should be backed up 2x daily. An example of this configuration etc. (I made those numbers up).
Please put some quantifiable examples for some better, best practices.
