RDX is a solution based on changeable Hard Disks as well as Solid State Drives for storing big amounts of backup data. It uses SATA for connecting the changeable media in the drive and the USB port with external drive or SATA with internal drive for the connection to the computer. WORM media (write once read multiple) are also available.

Creating a new Drive Group
It's recommended to create new Drive-Group to which RDX Drive will be added. To do this go to "Components -> Drives" and create a new drive group called "RDX" with the "New Group" Button:
Before you can configure the RDX Drive on Linux, you have to check
which device Name is used for the RDX Drive. If you attach the RDX Drive
to the Linux-System, most distributions will automatically mount it
If this is not the case, please check via the "dmesg" command
which device is used for the RDX Drive (usually
It is absolutely necessary that each time you change the RDX drive it is detected with the same Device Name - this can be done with a so-called UDEV rule.
It is also recommended to format the inserted "RDX Tapes" with a common Linux File System (ext3/reiserfs/xfs).
Adding a new drive on Linux Systems
The drive on Linux systems is added with the following options:
Drive: As shown in this screenshot:
Path for removable media: device name of your RDX Drive (See device configuration) Device Path: mount point where the media will be mounted Auto Unload: yes Mount command: mount Unmount command: umount Eject command: eject
After adding the drive, continue with the general steps.
Adding a New Drive on Windows Systems
After the drive group has been created, continue by adding a new drive to the group. To do this, select the drive group and click the "New Drive" button. The drive should have the following settings:
Drive Number: will be automatically assigned Drive Name: will be automatically assigned Loader: No Loader Drive Type: DISK_CHNG Device Server: your backup server or the system to which the drive is attached Drive Group: RDX (respectively the one you created above)
Path for Removable Media: Volume Name of the Disk-Change media with Directory, the Directory has to exist on the media before adding it to the mediapool!
The options in the second window are left empty

If not, please create it with the following options:

After these steps are done it is now time to add your first RDX media to the media pool. In "Components -> Media pools" select the created media pool "RDX-Pool" and click the "New Media" button.
Add the RDX Drive currently inserted with the following options:
Repeat this step for all your RDX changeable media.
