backup in the desktop-pc-times with HDDs i used Boot-CDs of backup-software to backup systemdrives.
Now on Ultrabook 1TB SDD i used AOMEI Backupper. beside that i use glary backup on a different SSD. But i cant identify. Forgot to name the drive!
maybe its Windows 10 backup. one folder is called: WindowsImageBackup. directory showing 193TB used. no further data visible showing size.

1. is the latter Windows 10-systemdrive-backup?

2. if drive cannot boot how to recover since i didnt make a bootable stick yet?
Must the backup then on a bootable stick or better getting an external optical drive or making a bootable external SSD-drive?
Many thanks.
