2. warning about restoring a 100G image to a 50G partition is not relevant
3. network device information is not relevant
4. information about the partition currently being zeroed is MISSING
5. backup (all):
6. warning about restoring a 100G image to a 50G partition is not relevant

9. backup (local use)
10. network device information is not relevant
11. restore (local use)
12. network device information is not relevant
13. restore (all)
14. information about the partition currently being restored up is MISSING
