During the DR setup, you will be asked whether to retain storage devices on the new system or restore storage devices from the original system. Differences are described here.
Storage configuration of the new system is retained after system metadata restore completes. Schedules from the original system are updated to use the default device on the new system.
Example:
Original system: 2 backup devices, D2DBackups and NewBackups. Backups for Client1 go to NewBackups.
New system: 2 backup devices, D2DBackups and MoreBackups.
After the restore, the new system still contains devices D2DBackups and MoreBackups. Since the original NewBackups device does not exist, the schedule for Client1 is updated so that its backups go to the default device, D2DBackups.
Storage configuration of the original system is restored. Schedules from the original system use the original configuration.
In the example above, backups for Client1 continue to go to the NewBackups device.
