Question 12 of 144

A server administrator is restoring a file server from a full backup taken 7 days ago and incremental backups taken daily. The restoration fails with an error about missing catalog files. What is the most likely cause?
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
✓
The incremental backup chain is broken
Restoring from incremental backups requires a complete chain from the last full backup. If any incremental backup in the chain is missing or corrupted, the restore will fail. Corrupted full backup media would cause a different error. OS compatibility issues would likely appear earlier. Hard drive failure would be a hardware error.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The hard drive on the file server has failed
Why it's wrong here
Hard drive failure would cause hardware errors or I/O errors, not a missing catalog files error.
- ✗
The backup software is not compatible with the current OS version
Why it's wrong here
Incompatibility would typically cause an initial backup or restore failure, not a missing catalog error.
- ✗
The full backup media is corrupted
Why it's wrong here
Corrupted full backup media would likely produce a read error, not a missing catalog files error.
- ✓
The incremental backup chain is broken
Why this is correct
A broken chain (e.g., a missing incremental) prevents the restore from completing, often resulting in a catalog error.
