We are running synchronized Web Crossing servers (distributed servers/master-slave/source-mirror). Are the databases identical on the machines? In other words, is it sufficient to back one of them up, or do we need to back them both up?
Answer:
Yes, the database is identical on all machines.
You may perform a manual backup on any node in the cluster via the backup control panel at any time.
However automatic (scheduled) backups occur only on the master for performance reasons.
