Backup and restore Qlik Sense
To ensure that your Qlik Sense site can be recovered in the event of a system failure or when a node in your deployment needs to be moved or replaced, we recommend that you create regular backups. These backups are used to restore your Qlik Sense site when needed.
If you creating a backup to upgrade from a synchronized persistence deployment to a shared persistence deployment, see Upgrading and migrating from synchronized to shared persistence.
To back up a deployment running Qlik Sense 3.2.x or earlier, refer to the documentation for the release that you are running.
To backup a Qlik Sense site, you must back up the following:
- Qlik Sense certificates
- Qlik Sense Repository Database
- Shared persistence file share
Qlik Sense certificates
Qlik Sense uses certificates to secure communication between components that are installed on different computers. It is recommended that you back up the certificates on the central node in a Qlik Sense site immediately after installation, so that they can be restored if needed.
Backed up certificates can be used to restore certificates on the same node as they were exported from. A backed up server certificate can also be moved from one node of a Qlik Sense site to another node in the same site. For more information, see Restoring certificates.
For more information about how to back up the Qlik Sense certificates, see Backing up a Qlik Sense site.
Qlik Sense Repository Database
The Qlik Sense Repository Database is a PostgreSQL database that contains system data and meta data about apps. The Qlik Sense Repository Database can reside on the central node or on another computer. If the Qlik Sense Repository Database was installed during setup it will be located on the central node. If the Qlik Sense Repository Database was installed manually, it may be located on another computer.
The Qlik Sense Repository Database should be backed up on a regular basis to avoid data loss.
For more information about how to back up the Qlik Sense Repository Database, see Backing up a Qlik Sense site.
For more information about how to restore the Qlik Sense Repository Database, see Restoring a Qlik Sense site.
Shared persistence file share
The shared persistence file share is used to store Qlik Sense app data, such as visualizations, and dimensions and measures. It also stores static content, such as images and extensions, as well as system logs. It is accessible to all nodes in your Qlik Sense site. The file share can reside either on the same server as the central node or on another server.
The file share should be backed up on a regular basis to avoid data loss.
For more information about how to back up the file share, see Backing up a Qlik Sense site.
For more information about how to restore the file share, see Restoring a Qlik Sense site.
