2.5.1 Automatic backups

Automatic backups for Cloud DBaaS (regardless of the type of resource, whether shared or dedicated) are incremental and performed if the service status is "Active" or "Limited".

Below is an example of an automatic daily backup for a database that is edited every day.
  • Let's assume that you start on a Monday: so you will have a full copy of the database after the first backup.
  • For the next six days, only the changes to the database will be saved.
  • On the eighth day (Monday of the following week), the system will merge the first (full) copy with the subsequent version.
  • On the ninth day (the following Tuesday), the same process will begin again, updating the last backup with the changes made to the database the following day.

There will always be 7 copies of the backup available for 7 days, unless a backup is restored.
