For Windows clients, a bare metal backup may be used to capture the boot volume (usually the C: drive) allowing for rapid recovery in the event of a system or drive failure. Note that in Unitrends release 7.4 and higher, regular file-level backups contain this system information, eliminating the need for bare metal backups for many clients. For requirements and details, see Windows Hot Bare Metal Protection. To protect the operating system for non-Windows clients, see Bare metal procedures by client operating system.
