Snapshhot does not seem to be working all the time

Can I bother one of you to login to my site and check my snapshot setup --

I have a system cron running to execute the wp-cron -- every 15 minutes --

I am uploading things to S3 -

Since I am having some issues figuring out how snapshot works -- I want to make sure I have it setup right --

MY main site theactionsociety.com -- is backing up all files and DB
each site is backing up just their DB and I do not see how to backup that sites uploads file -

Some of them look like they are running on a regular basis -- but some will not run at all --

I appreciate it
