MODX Cloud Automatically Backs Up Your Sites
A Cloud Backup is a copy of all the files in the public web directory of your Cloud, plus a copy of its database.
Backups count toward the total amount of storage that you are using.
Each Cloud is automatically backed up daily. You can configure how many days' worth of backups are kept, from 1 to 30 days, on the Backups tab of the Cloud Edit page:
You can also have Backups created at any time, from a number of convenient places in your Cloud Dashboard. These backups are not automatically deleted.
