Although I've been using backup/restore software for decades (Macrium and Hasleo) I'm puzzled about how Delta Restore works.
I only use Full Backup and therefore Full Restore options since my current C: is only a 512GB SSD.
Backup takes < 5 minutes writing to an external SSD.
So Delta Restore only restores the changes in the file system.
After a backup, and before the restore, a file system will have had many changes including sector positional changes.
How does it know which sectors haven't changed.
Can anyone enlighten this "relative" newbie?
Thanks.
