If the hard disk is 80G in total, it cannot be placed in a partition. If one partition of the hard disk is full, it can be placed in another partition for backup. Backup can also be said to be a compressed file, but your hard disk is 80G in total and full, it cannot be backed up again!
You have run out of 80G. How can I put your backup. The ghost backup of 80G files is definitely not 80G, which is related to the specific compression ratio.
It can compress files, but the amount of compression is not certain. It depends on the files in your hard disk. Generally, if there are many files, the compression ratio will be large. Your original hard disk has already been installed, and of course it cannot be placed in it
