Hi, 

I notice that Automatic Synthetic Fulls for Qumulo (created automatically by a plan) by default run only every 90 days. What's the rationale behind this? Our Retention Time is only 90 days!

Thank you.

It seems the 90 days was a test from one of my colleagues 🤔.

Hi ​@iConsultant ,


If extended retention rules are not configured, then the system ensures that a synthetic full backup job is run at least once every 90 days. Please refer the below article, which explains the rules for Automatic Synth full backups (Refer Point 6 on the below doc)
