[dba-Tech] Question about EaseUS ToDo Backup

[Arthur Fuller]

Does anyone use this free backup program? It employs several terms that I
don't quite understand, and there's no help available to help me
distinguish them. Three kinds of backup are available:

1. Disk/Partition backup
2. File backup
3. System backup

The second one is obvious, but what does the third option do that the first
doesn't, and vice-versa?
