LPIC-1 Devices, Filesystems and FHS Practice Question
An administrator plans to back up the /home filesystem using dump. Which option to dump is required to perform a full backup?
⚠ Common exam trap
Test-takers frequently confuse the -0 option with a generic flag or think -1 is the full backup because it is the lowest non-zero number, but dump levels start at 0 for full backups.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
-0
The dump utility uses dump levels (0-9) to control backup depth. A level 0 dump performs a full backup of the specified filesystem, copying all files regardless of modification time. This is the required option for a complete backup of /home.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
-f /dev/st0
Why it's wrong here
-f specifies the backup device, not the backup level.
- ✗
-u
Why it's wrong here
-u updates /etc/dumpdates, but does not set backup level.
- ✓
-0
Why this is correct
Level 0 is a full backup.
- ✗
-1
Why it's wrong here
Level 1 is an incremental backup, not full.
