Creating a Backup & Disaster Recovery Plan for Liferay Digital Experience Platforms

This article gives an overview of a backup & disaster recovery environment that is necessary when starting a Liferay Digital Experience Platform (DXP) project. This backup will often be referenced by Liferay Support Engineers as it is crucial to have a stable and working backup of the production environment to recover with if the production instance becomes unusable.

Resolution

Backing up a Liferay DXP installation is covered within the DXP 7.0 and the DXP 7.1 Deployment Guides.

To summarize, please remember to make a copy of the following:

  1. Liferay Database
  2. Document_Library and File System Data or the location of the Document_Library files
  3. Relevant app server settings
  4. Portal-ext.properties file(s)
  5. Any customization, such as themes, custom apps and modules
  6. Search Indexes (in some cases this might take days to create)

Each of these should be backed up on a regular basis.

Additional Information

Please remember that regardless of where the Document Library is stored, either in the database or file system, the backup of the Document Library needs to be in sync with the backup for the platform because failing to do so will cause conflicts and errors due to missing files.
