Question

Difficulty: EasyBusiness Continuity and Disaster Recovery

A network administrator needs to restore a critical network monitoring server after a hard drive failure on Thursday morning. The backup strategy consists of a full backup performed every Sunday at midnight and incremental backups performed each night from Monday through Wednesday at midnight. Place the backup recovery steps in the correct sequential order required to fully restore the system.

  1. 1Restore the Sunday full backup
  2. 2Restore the Monday incremental backup
  3. 3Restore the Tuesday incremental backup
  4. 4Restore the Wednesday incremental backup

Answer

To restore a system managed with incremental backups, first restore the latest full backup (Sunday), followed by each incremental backup in chronological order (Monday, then Tuesday, then Wednesday).
An incremental backup sets up a chain where each backup relies on the previous one. To recover the system completely, the baseline full backup from Sunday must be restored first, followed by every individual incremental backup taken since then (Monday, Tuesday, Wednesday) in chronological order.

Step-by-Step Solution

1
Select and restore the base system image
The Sunday full backup is restored
All incremental restoration operations require the baseline full backup to establish the file structure and initial state.
2
Apply subsequent incremental backups chronologically
Apply Monday, Tuesday, and Wednesday incremental backups in exact sequential order
Each incremental backup contains only the delta since the immediately preceding backup. Skipping or misordering any day results in missing or corrupted files.
