Backups for Mendix on Azure

Last modified: November 1, 2025

Introduction

Mendix on Azure integrates backup and restore functionality that allows you to create and restore database snapshots for your Mendix application environments hosted on the platform.

Backup snapshots include both the database and the file documents associated with the Mendix app environment.

Enabling Backups

To start using backups, select Try new Backup and Restore on the Backups page in the Mendix for Kubernetes portal.

You must have Manage Apps Backups permission for the namespace to use this feature.

Creating a Backup

On the Apps page, select your app.
Click Backups in the navigation pane.
Choose the environment to back up from the environment dropdown.

Backups cannot be created while the environment is in any of these states:

Creation in progress
Creation failed
Deployment package is being deployed
Environment is in transition state (runtime processing)

Click Create Backup.
Monitor progress in the Status column.

Tables are locked during backup creation, so if you attempt to start the environment while a backup is in progress, you may encounter a timeout error. Wait for backup completion before restarting.

Backup Snapshot Details

Click More Options ( ) > Details to view:

Backup Detail	Description
Status	Backup status: Processing, Failed, or Finished
Snapshot ID	Unique identifier
Created on	Date and time created
Deployment Package	Version at backup creation
Comment	User-added comment

Deleting a Backup Snapshot

To delete a backup snapshot, perform the following steps:

Click More Options ( ) next to the desired backup.
Click Delete.

Restoring a Backup Snapshot

Restore requires Manage Apps Backups and Stop Apps permissions on the namespace.

To restore a backup snapshot, perform the following steps:

Stop the app if running by clicking Stop Application.
Click More Options ( ) next to the backup to restore.

If restoring a backup from a different Mendix model version, you will be warned. You must deploy the matching model after restore.
Click Restore.
Select the destination environment (for example, restoring production backup to acceptance).

Avoid modifying the environment during restore.

The environment details page will show restore progress. Activity log shows FINISHED on success or FAILED on failure.

Uploading a Backup Snapshot

To upload a backup, perform the following steps:

Click Upload Backup.
Select the archive to upload (must contain a Full Snapshot).

Uploaded backups appear in the backup list and can be restored normally.

You can upload backups from Mendix Cloud to migrate app data to Mendix on Azure.

Downloading a Backup

To download a backup, perform the following steps:

Click More Options ( ) > Download on the desired backup.
Click Start to request the download.
After processing completes, use the Download button to retrieve the archive.
Optional: Click Show URL to copy the download link.

File size cannot be estimated before request completion.

Backup archives are compatible with Mendix Cloud backups allowing migration from Mendix on Azure to Mendix Cloud.

Automated Backups Schedule

Frequency	Timing	Type	Retention Period
Nightly	Every night	Automatic	14 days (from previous day)
Weekly	Every Sunday	Automatic	3 months (from previous day)
Monthly	First Sunday of each month	Automatic	1 year (on that Sunday)
On demand	When triggered	Manual	14 days (from previous day)

Backups older than retention are deleted automatically but can be manually removed earlier. To keep backups longer, download them locally.

Automatic backups only run when the app is deployed.

Retention Notes

If the first nightly backup occurs after the first Sunday, no monthly backup will be retained that month. Download a nightly or weekly backup to extend retention.

Known Limitations

Partial data restoration may occur if a restore process fails.
No API support exists currently for backup and restore.
Although the portal UI suggests cross-namespace restores, only restores within the same namespace are supported.
