    • When a backup view is open, that backup will not be deleted to make room for new backups until it is closed or unless the storage system runs critically low on resources. If you view the oldest backup, and the maximum number of backups is reached, new backups cannot occur until the view of the oldest backup is closed (as described in the next step).

    Appendix A: Disk Configurations Your storage system supports the following types of disk configurations: • Linear: A linear configuration is similar to using multiple hard disks in a regular computer. Each disk is an independent entity, and the data on it is self-contained. You can add or remove the disks without affecting the other disks.

  • Page 96: Adding Hard Disks

    You can use RAID 5 only if your storage system has at least three disks. If the disks are not the same size, the smallest of the disks determines how much disk space is available for data. For example, if one disk is 300 GB, one is 400 GB, and one is 500 GB, only 300 GB from each disk can be used.

Any disk that you install will not be used unless you subsequently reconfigure the storage system. Warning: Reconfiguring your storage system disks deletes all the data on your storage system.

If you swap the disks when the storage system is not running, you can swap all four disks, and the system will function as it previously did when you restart it. Notes: For RAID 5 + spare, if you swap the disks when the storage system is running, one of the swapped disks must be the spare.

    B.1 Disconnecting from Shared Folders If you need to reconfigure the disks in your storage system or shut it down for any reason, all users should disconnect from the shared folders to ensure that the process proceeds smoothly. You might also want to have users disconnect from the shared folders if you want to change their access rights, since otherwise the change will not take effect until the user shuts down the computer.

To ensure that you don’t use up disk space unnecessarily, be sure to delete any extraneous backups on the storage system. Compare the Backup disk ID on the Status page in DiskSafe Express with the Backup Disk ID on the Backups page in the Manager to determine which backup is actually being used.
