NSX-T backup is failing with error code:99

Backing up your VMware NSX-T Data Center (NSX-T) is an absolute must for any business that relies on a network virtualization platform. Focusing on this will help you ensure availability, recoverability and integrity of your system. 

Establishing a backup strategy that fits your business' needs is critical. This includes the frequency of backups, how long they are retained for & amp; ensuring that all storage practices follow necessary security regulations. To assure the effectiveness of your NSX-T backups, it is highly recommended to regularly check the restoration procedures. This will guaranteed the trustworthiness and dependability of your backup files.

Disaster Recovery

NSX-T backup plays a vital role in disaster recovery scenarios. By regularly backing up NSX-T configurations, policies, and network state information, organizations can restore their network infrastructure swiftly in the event of a disaster or system failure. This ensures minimal downtime and enables business continuity.

Configuration Restore

NSX-T backup allows organizations to restore network configurations in case of accidental changes, misconfigurations, or human errors. It provides the ability to revert to a known working state, minimizing the impact on network operations and reducing troubleshooting time.

Compliance and Auditing

Backup of NSX-T configurations helps organizations maintain compliance with regulatory requirements. It provides a point-in-time snapshot of network policies, security configurations, and other settings, which can be used for auditing, compliance reporting, or forensic analysis purposes.

Upgrades and Migrations

NSX-T backup allows for smoother upgrades and migrations to new versions or hardware platforms. In case of any issues during the upgrade or migration process, having a backup ensures the ability to roll back to the previous working state, avoiding potential service disruptions.

Configuration Consistency

NSX-T backup facilitates maintaining consistency across different environments, such as development, staging, and production. By restoring a backup, organizations can replicate network configurations from one environment to another, ensuring consistency and reducing the risk of inconsistencies that may lead to operational issues.

Recovery Point Objective (RPO)

Regular NSX-T backups help define and achieve desired Recovery Point Objectives (RPOs). By scheduling backups at regular intervals, organizations can ensure that the data and configurations captured in the backup are up to date and aligned with their recovery objectives.

NSX-T backup is failing with error code: 99

Not long before I was working on a solution with one customer and we figured that their NSX-T backups were failing with error code 99.

They tried to check all public documentation and couldn't find a solution. It becomes really difficult to troubleshoot, if you do not have any public documentation available, as you do not know where to look.

But in this instance we knew exactly what to check and trust me solution was very simple. I asked customer to verify if they have enough space available in the backup directory, upon checking we found that there was no space left and that was causing backups to fail.

As NSX-T do not rotate old backups we need to perform this task manually or you can setup a scheduled task for it. Please refer VMware official documentation for rotating backups "Remove Old Backups". 

After space was created and a fresh back up was triggered. It was successful.

I hope I was able to add value, if your answer is yes, then don't forget to share and follow. 😊
