I backed up a Windows 10 system to an external USB disk drive using the backup utility that comes with the operating system that can be run by right-clicking on the Windows Start button then choosing Control Panel then Backup and Restore (Windows 7), which is found beneath System and Security, and then choosing Create a system image. If you create a system in that manner and then later wish to know the date and time you backed up the system without reattaching the drive you used, you can do so from a command prompt window with administrator privileges by using the
wbadmin get versions command as shown
below:C:\WINDOWS\system32>wbadmin get versions
wbadmin 1.0 - Backup command-line tool
