Acronis Backup & Recovery 11.5 supports external SCSI devices. These are devices connected to Fibre Channel or using the SCSI, iSCSI, Serial Attached SCSI (SAS) interfaces. Also, Acronis Backup & Recovery 11.5 supports USB-connected tape devices.
In Windows, Acronis Backup & Recovery 11.5 can back up to a tape device even if the drivers for the device's changer are not installed. Such a tape device is shown in Device Manager as Unknown Medium Changer. However, drivers for the device's drives must be installed. In Linux and under bootable media, backing up to a tape device without drivers is not possible.
Recognition of IDE or SATA connected devices is not guaranteed. It depends on whether proper drivers have been installed in the operating system.
