Hi! Wanted to ask if this is supported to backup my system drive image to extarnal HDD connected via USB. The information I would like to know is if the backup can be bootabkle (same way as backing up to DVDRW drives). Something called bootable capsule but on extarnal drive, will the USB drive be self-bootable? If so, will be all data on my extarnal drive deleted always I perform system backup?
