Automatic Mirroring
Disaster recovery sites check for newly available checkpoints based on the
mirroring_interval configuration option, set when the data grid is created.
Mirroring interval has no effect on a primary data grid. Setting a mirroring interval is only necessary at the mirror grid.
By default, the system checks for new checkpoints after every 30 seconds. This option can be changed after creating a data grid by using the tibdg grid modify command.
Note: Mirroring can be disabled entirely by setting
mirroring_interval to 0. This can later be set to a value greater than 0 to restart mirroring.
