supported storage

RDX drives are supported by Acronis Cyber Backup 12.5 as a backup destination. They are treated as a regular local backup location.

If you are backing up to a shared RDX drive with swapped disks, set up automatic cleanup via a command or script, so that the disk content is erased before backup starts. See Acronis Cyber Backup 12.5 and Acronis Cyber Backup Cloud: Backing Up to Removable Devices with Regular Drive Swaps This way each disk will contain one full backup.
