Casper? Never heard of it!
I've been using "Ghost" in one form or another since 1997 about the time it was first released. But never heard of "Casper".
I wonder if they are any relation? (just joking).
Since that 25 yr old program does indeed have an option to "Verify" it's backup Image file, I would think that most other Backup programs do as well. Or, at least they should!
I think it's hilarious, that Ghost still works as well today as it did 25 years ago. It doesn't care what OS it's backing up, whether it's DOS, or Win-11, or even a data disk, with no operating system on it at all. It just backs up what it sees, bit by bit. I still use it every few days, to back up my current OS....Windows 11/Pro/64.
On the old spinners, I used to do a Ghost Backup followed immediately by a Ghost Restore, for the perfect 'Defrag'. It never failed!
Years ago, I ran Ghost 11.5 from a bootable floppy disk. Today I run it from a bootable flash drive. It still runs the same.
Cheers Mates!
