(!) Standalone versions of Acronis Cyber Protect and Acronis Cyber Backup (Acronis Backup & Recovery) do not support tapes.
Supported tape devices
Acronis Cyber Backup supports external SCSI devices, in particular, devices that are connected to Fibre Channel or using the SCSI, iSCSI, Serial Attached SCSI (SAS) interfaces. Recognition of IDE, SATA, or FireWire connected devices is not guaranteed.
Coexistence with third-party software
Acronis Cyber Backup Advanced may fail to work with tapes on a machine where third-party software with proprietary tape management tools is installed. To make sure Acronis Cyber Backup Advanced can properly access tapes in such an environment, you need to uninstall or deactivate the third-party tape management software.
Interaction with Windows RSM
Unlike Acronis Backup & Recovery 10, later versions do not use Windows Removable Storage Manager. During an upgrade from Acronis Backup & Recovery 10, Acronis Backup & Recovery 11 and Acronis Cyber Backup Advanced transfer the necessary information from Windows RSM to its own database in the new format.
When detecting a tape device, Acronis Cyber Backup Advanced takes control over this device (unless it is being used by other software) and disables the tape device in Windows RSM.
(!) As long as you want Acronis Cyber Backup Advanced to work with the tape device, make sure that neither a user nor third-party software enables the device in RSM. If the tape device was enabled in RSM, repeat the tape device detection.
