Keep in mind that the mirroring capability included in Backup for Workgroups is designed to mirror your backup data only. It should not be confused with a general purpose mirroring program. The mirroring function does not cover ALL the data that resides on the computer hosting the Backup for Workgroups Backup Server. It does mirror the backup data that is stored in your Backup Storage Location, but it does not capture anything else residing on this same computer.
Use the Add, Modify, Remove, Pause, Options and Priority Up and Down buttons when you need to manage your Mirror Group.
At any time, you can add more storage capacity to your Mirror Group. Please note that all storage devices within the Mirror Group must be online and accessible for the mirroring to occur; however, if any one of the Mirroring devices is offline, your backups will not be affected.
If you choose to use Interlocked Mirroring, you must have the same number of Mirroring devices as you do in the Backup Storage Group. In other words, if you have 2 devices in your Backup Storage Group, you must have 2 devices in your Mirror Group. And, with Interlocked Mirroring, the Mirroring drives need to have the same amount of storage capacity as their corresponding Backup storage devices.
If you choose to use Ad-Hoc Mirroring, the sum of your Mirroring capacity needs to be greater than or equal to the total capacity of the Backup Storage Group. You do not need to match the same number of devices as you do if you were using the Interlocked Mirror.
You will need to use the Modify button accessible in the Mirror Group panel when a mirror device IS NOT accessible. Two common situations that may make a mirror device inaccessible occur when: (a) a USB device changes drive letters; and (b) a network share point experiences a change in name. When you press the Modify button, a dialog appears that allows you to change the name of the highlighted mirror device.
Use the Remove function when you want to stop using a particular mirror device and eliminate it from the Mirror Group. If you Remove all mirror devices, the mirroring function is turned off.
Use the Pause function when you want to temporarily disable the mirroring function. This is handy when you need to perform maintenance on one of your mirroring devices.
Use the Options button to specify the Mirror Mode you want to use (Interlocked or Ad-hoc), change the throttle settings or specify a blackout period.
Priority Up /
When you are using Interlocked Mirroring, use the priority up and down buttons to match the order of your mirroring devices to correspond to the order of storage devices. Interlocked Mirroring replicates the first device in the Backup Storage Group to the first device listed in the Mirror Group, and so on through the list. In Ad-Hoc mode, the Backup Storage is copied to the Mirrors as a sum-total group, with priority given to the first mirroring device.
