Backup overleaf server

Start from the simple installation configuration shown in the issue and inspect the mounted sharelatex_data, mongo_data, and redis_data volumes. Determine which data must be backed up and how recovery on another server should be verified, then document a tested backup and restore procedure for this setup.

Hello everyone!!
I'm looking which is the best way to backup the whole instalation of my overleaf instance and recovery on another server. I have the toolkit "simple" installation.

Below you will find the doctor's scrpit output.
