Coexistence with third-party software
Acronis Backup & Recovery 11.5 cannot work with tapes on a machine where third-party software with proprietary tape management tools is installed. For Acronis Backup & Recovery 11.5 to use tapes on such machine, you need to uninstall or deactivate the third-party tape management software.
Interaction with RSM
Unlike Acronis Backup & Recovery 10, Acronis Backup & Recovery 11.5 does not use Windows Removable Storage Manager. During an upgrade from Acronis Backup & Recovery 10, Acronis Backup & Recovery 11.5 writes the necessary information from RSM to its own database in the new format.
When detecting a tape device, Acronis Backup & Recovery 11.5 disables the device from RSM (unless it is being used by other software). As long as you want Acronis Backup & Recovery 11.5 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.
