Backup Health Check (NAS)

The goal is to ensure that the data backups are reliable, up-to-date, and readily accessible in case of data loss, system failures, or other unforeseen events. Here are the key aspects of a backup health check for NAS

(File Sharing & Data backup and redundancy)

Backup Schedule

The health check should confirm that the backup schedule is configured appropriately to perform regular backups at the desired intervals. This includes checking the frequency of backups (e.g., daily, weekly), the time of backup execution, and any specific backup retention policies in place

Backup Storage

The health check should ensure that the backup storage media (such as external hard drives, tapes, or cloud storage) is in good condition and has enough capacity to accommodate the backup data.

Backup Logs and Alerts

The backup system keeps logs that record backup success, failures, and any warning or error messages. The health check should review these logs to identify any issues that need attention.

Case Study Drive 2 have a power outage

NAS Drive 2 experienced an unexpected power outage without any prior warning or indication.

Troubleshoot

  • Data Integrity Check:

    • We verified the other NAS drives' integrity and data redundancy in RAID 5 configuration to ensure the data was still accessible and protected.​

  • Swapping Drives:​

    • As a precaution, we moved the drive from NAS Drive 2 to another slot to see if the problem followed the drive or remained isolated to Drive 2.​
