Note: please note that Liferay has renamed its Liferay Experience Could offerings to Liferay SaaS (formerly LXC) and Liferay PaaS (formerly LXC-SM).

Issue

  • From one day to another our backup size is reduced with considerable amount.

Environment

  • Liferay PaaS

Resolution

  • When a backup is created, it saves the content of the data folder and creates a database dump.
  • Download and compare the content of the last Backup with the larger size to the content of the smaller Backup.
  • The documents and media library can contain some files which have been deleted during the period between the two backups. This could be for example a larger LAR file of a failed propagation, a heap dump, or an emptied Recycle bin, etc.
  • Comparison / checking the discrepancies of the two backups can extract more information.
  • See the documentation on how to download backups: https://learn.liferay.com/web/guest/w/liferay-cloud/platform-services/backup-service/downloading-and-uploading-backups
