1 Introduction
Backups in the Mendix Cloud have two parts: database and file documents. A backup is created every night or on-demand, as described in 3 Backups. For the database, a full backup is made. File documents are backed up incrementally.
Additionally, a replication/failover add-on can be purchased that will enable incremental backups with a 15 minute interval for the database and file documents.
2 Nightly Backups – Creation and Retention Schedules
The pruning schedule applies to nightly backups and backups initiated by users. If you want to keep a backup for longer than scheduled, you will have to download it.
The following backups are retained:
- Last two weeks: every day
- Last three months: every Sunday
- Last year: every first Sunday of the month
The start time of nightly backups is between 21:00 and 05:00 in the local time of the region.
3 Backups
The Backups page under the Operate category presents options for managing your backups. These are described below.
3.1 Creating a Backup
This will automatically generate a backup from your application data.
3.2 Uploading Data
You must stop the application before executing this process. This functionality is used to transfer data from your local or on-premises application to the cloud environment. This will not add a backup to the backup list but directly update the application with the newly uploaded data. Your environment will be cleared completely. The deployment package, uploaded files, and database will be removed. If you are uploading data to the production environment, any published app services will be unpublished.
You can upload two types of data:
- Database
- Uploaded files (zip or tar.gz)
3.3 Restoring a Backup
You can choose the destination to which you want the environment to restore the backup. This allows you to, for example, restore a production environment backup to an acceptance environment.
If you restore a backup that was originally deployed on an older Modeler version, you will get a warning. You can still restore the backup, but you have to deploy the older model later on.
3.4 Downloading a Backup
These are the options:
- Full Snapshot
- Database Only
- Files Only
As the download files are generated “on the fly” (meaning, while in progress), it is not possible to estimate the file size before downloading. Your browser will not show a progress bar.
