Disaster Recovery Planning Options with a NAS


Disaster recovery planning is crucial to ensure the continuous availability of data in the event of a disaster. Network-attached storage (NAS) devices offer several options for disaster recovery, allowing organizations to protect their data and minimize downtime. In this article, we will explore some of the options available for disaster recovery planning with a NAS.

1. Backup to an offsite location

One of the most common disaster recovery strategies is to regularly backup data from the NAS to an offsite location. This can be achieved by utilizing cloud storage solutions or physically moving backup tapes or external hard drives to a separate location. It is recommended to perform backups on a regular schedule (e.g., daily, weekly) to ensure minimal data loss in the event of a disaster.

2. Replication to a secondary NAS

Another option is to implement replication between the primary NAS and a secondary NAS located in a different geographic location. This can be achieved through synchronous or asynchronous replication, depending on the organization's requirements. Synchronous replication ensures that data is simultaneously written to both NAS devices, providing real-time data protection. On the other hand, asynchronous replication introduces a slight delay between the primary and secondary NAS, which may result in minimal data loss.

3. High availability (HA) clustering

For organizations requiring the highest level of availability, implementing a high availability (HA) cluster with multiple NAS devices can be an option. HA clustering provides redundancy and ensures that data remains accessible even if one or more NAS devices fail. In a clustered environment, if a primary NAS fails, another NAS within the cluster takes over seamlessly, minimizing downtime and ensuring continuous operations.

4. Integrate with a disaster recovery service provider

Some NAS vendors offer integration with disaster recovery service providers, enabling organizations to leverage their expertise and infrastructure. These service providers often offer additional features such as data deduplication, compression, and encryption to further enhance disaster recovery capabilities. By partnering with a reliable service provider, organizations can achieve a comprehensive disaster recovery plan with minimal effort.


When it comes to disaster recovery planning with a NAS, organizations have multiple options to choose from. Whether it is backing up data to an offsite location, implementing replication to a secondary NAS, utilizing high availability clustering, or integrating with a disaster recovery service provider, each option offers different levels of protection and recovery time objectives. Therefore, it is essential to assess the organization's requirements and select the most suitable strategy to ensure business continuity in the face of a disaster.
