6.8.2. Backup modes

Backup modes 1/1

Offine backup

An offline (cold backup) is done when all system components are stopped. Files, metadata, and configuration data are then considered stable and can be backed up without concern for changes being made by users or external applications at that time. The optimal conditions for an offline backup when the following situations occur:

  • All users are disconnected from the system.
  • All Web-tier processes are stopped
  • All back-end processes are stopped
  • All database processes are stopped

Warm online backup

A warm online backup is done when users still have access to the system, but some level of system functionality is restricted to make the backup less complicated and to ensure consistency between the files and metadata being backed up.

Hot online backup

A hot online backup is done when the system is backed up and no user activities are restricted. Core content, process, full-text indexing, and publishing activities all continue during this type of backup.
