Helix Core Server Administrator Guide: Multi-Site Deployment (2019.1)

Backing up services

How you back up a service in your multi-site deployment depends upon the service type:

   
Broker
  • stores no data locally
  • back up its configuration file manually
Proxy
  • requires no backups and automatically rebuilds its cache of data if files are missing
  • contains no logic to detect when diskspace is running low. Periodically monitor your proxy to ensure it has sufficient diskspace.
Server
  • Although a checkpoint (p4d -jc) is NOT supported on an edge or replica server, you CAN take a checkpoint dump on an edge or replica server (p4d -jd). See the Helix Core server (p4d) Reference.

  • Maintaining journals:
    • on edge servers is a best practice
    • on replica servers is optional, and you can disable such journals by using p4d -J off
  • You can have triggers fire when the journal is rotated on an edge or replica server. See "Triggering on journal rotation" in Helix Core Server Administrator Guide: Fundamentals.
  • Journal rotation on a replica or edge server begins AFTER the master has completed its journal rotation
