Notes: Any non-removable disk that appears as a local drive to a server protected by CA ARCserve D2D will also be protected. This includes any Fibre Channel (FC) attached Storage Area Network (SAN) disks, or iSCSI disks. For iSCSI disks, CA ARCserve D2D can protect system and data disks; however, iSCSI system disks are not supported for BMR. Therefore, you should only use iSCSI for data disks. Supported file copy destinations include Amazon S3, Windows Azure, Eucalyptus-Walrus, and NTFS local or network volumes (could be on iSCSI).

*1	FAT/FAT32 cannot hold a single file larger than 4 GB. If after compression the CA ARCserve D2D file is larger than 4 GB (because the source is very large), the backup will fail.
*2	CA ARCserve D2D only supports BIOS systems. UEFI systems are not supported. UEFI systems are supported by CA ARCserve D2D r16 Update 5 and later.
*3	A spanned volume cannot be used as a boot volume.
*4	The VHD mounted volume used as the backup destination should not reside on a volume which is selected as the backup source.
*5	When your system has multiple dynamic disks, BMR can fail. But, as long as the system volume is on a basic disk, the system should be able to boot. You can perform a restore of dynamic disks after the system has booted, by using the How to Restore Files/Folders procedure.
