When using Odoo Online, you can download a backup of your database at any time through the control center. You own your data! Odoo Online or Odoo Enterprise (On-premise or Odoo.sh) is the same software. Only the hosting and infrastructure are different: emails, backups, database redundancies, etc. Our cloud infrastructure runs on the latest version of Odoo with regular upgrades. On-premise users must use the latest stable version of Odoo. If you would like to switch from Odoo Online to Odoo On-premise, the best time to make this change is immediately following the release of the newest stable version.
