Once a friend told me that he wanted to backup drive C:\ to drive D:\ and he only wanted to just backup drive C:\ onto drive D:\. However, when he used the Windows Backup to do it, at the moment he could not see drive D: as an optional drive to back up to. Thus, he could not finish this job. Why cannot see the D:\ drive as an optional drive when backup C:\ drive to D:\ drive? Can backup C:\ drive onto D:\drive?


Take Windows 10 as an example, use the Windows Backup to backup system drive, you should click Start menu, select Settings, click Update & Security, then click Backup, finally, you can click Add a drive to choose an external hard drive or network location for your backups. As for backing up to other local partitions, you need use other ways. Because the Windows 10 can only support you backup to external hard drive or NAS, you cannot see the D: drive as an optional drive while you need to select the destination partition to store the system backup files.


How to backup C:\ drive onto D:\ drive? Here, with the help of AOMEI Backupper could be a good way to to it. But first, you need ensure that you have already partitioned your hard disk drive and there is a partition with drive letter D:.
