Backing Up Cache Data Using NCache


Cache data is a temporary form of storage on a device or system to speed up the performance of an application. Cache data is a high-speed data storage mechanism storing frequently accessed data for quick retrieval, reducing access and processing time.

Cache data is usually stored on a device's RAM (Random Access Memory) or SSD (Solid State Drive) to be cleared periodically for new data.

While cache data is essential for optimizing application performance, it's not a reliable storage mechanism. Over time, you can lose cache data due to system failures, crashes, or power outages, adversely affecting application performance.

Consequently, backing up cache data ensures data safety during system failures or crashes. Backing up cache data is handy for recovering lost or corrupted data and ensuring that your application continues to function smoothly without data loss.

Why Backup Cache Data?

Backing up cache data is essential for data loss prevention, protection against hardware failure, and disaster recovery planning. Data loss is a real and constant threat that can result in irreversible damage. This is why it's important to back up cache data to prevent data loss and protect data against hardware failure.

Preventing Data Loss

Data loss prevention is the most important reason to back up cache data. Cache data is usually stored in volatile memory, meaning it's lost during power outages or system crashes. If you don't back up cache data, you could lose it forever, resulting in potentially catastrophic consequences.

Hardware Failure Protection

Backing up cache data also protects against hardware failure. Computers, servers, and other hardware can fail due to various reasons, including wear and tear, power surges, and malware. Inconsistent cache data backup could result in significant downtimes and reduced productivity.

Disaster Recovery Planning

Another important reason to back up cache data is disaster recovery planning. Natural disasters like floods, hurricanes, and earthquakes can destroy hardware and data. A backup of cache data ensures that critical data is protected and quickly restored in the event of a disaster.

How to do Backup Cache Data in NCache?

Ncache provides multiple options for backing up cache data easily and flexibly. You can back up cache data by persistence or use NCache's backup and restore mechanism.

Persistence Backup With NCache

Persistence with NCache is a powerful feature that allows storing and maintaining data even during system failures and outages. Persistence involves writing data to durable storage such as hard drives, Solid state drives for later retrieval.


NCache provides persistence features to automatically write cache data to disk, ensuring high availability and data durability during mishaps.

There are several advantages to using NCache's persistence features. One significant benefit is the overall reliability and data availability since your data is saved to disk in real time.

Additionally, persistence with NCache can improve performance by reducing load times when you restart your system after failures.

Using persistence with NCache effectively ensures that your data remains reliable, available, and performant during unexpected failure events.

Data Backup and Restore With NCache

NCache provides data backup and restorations functionality using the import/export cmdlets. Backup and restore using Import/Export cmdlets in NCache is a helpful feature that allows you to take snapshots of your cached data for storage.

Import/Export Cmdlets can be particularly helpful in cases where you need to migrate your data to different machines or recover data after a system failure. Creating backups involves exporting your cache data to a file you can import and restore later.

One key advantage of using the Import/Export cmdlets functionality in NCache is that they are easy to use and provide a flexible way to manage your cached data. With these cmdlets, you can easily create backups of your cached data and restore your cache data from backup files. Additionally, Import/Export cmdlets allow you to specify the data you want to back up or restore, giving you fine-grained control over the backup and restore process.

Backup and restore using Import/Export cmdlets is essential for managing your cached data in NCache. By creating regular backups, you can ensure your data is always safe and accessible. You can easily manage your cached data using the flexible Import/Export cmdlets to suit your application's needs.

Best Practices for Backing Up Cache Data

The integrity and availability of cache data result from good practices during the backup process. The best practices for backing up cache data range from establishing regular backup intervals to storing backup copies in secure locations and testing backup copies to ensure validity.

By implementing these best practices, you can reduce the risk of data loss and improve your data management processes.

Regular Backup Intervals

Establishing a regular backup schedule is a fundamental procedure for ensuring data validity. The frequency of backups should depend on the amount of data stored in the cache, how frequently the data changes, and the degree of importance of the data.

For frequently changing data of critical value, consistent backups are necessary. Ideally, you should back up cache data daily, weekly, or monthly, depending on the modification frequency and importance.

Automate the backup process to ensure consistency and avoid human errors. Your backup system should also provide notifications of successes and failures on backup in case there's a need for corrective actions. Also, the backup process should be on off-peak hours to minimize the impact on system performance.

Storing Backup Copies In Secure Locations

Another best practice for storing cache data is storing backup copies in secure locations. You must choose a location not prone to fires, floods, and earthquakes. Store backup copies off-site or on the cloud to ensure high availability in disaster events.

It's also vital that you protect backup copies from unauthorized personnel access. Implement access control measures from passwords and MFAs(Multi-Factor Authentication) to ensure only authorized personnel can access backups. You can also encrypt backups to prevent data theft or tampering.

Additionally, periodically audit backup copies to ensure access controls and encryption mechanisms are functional.

Testing Backup Copies for Integrity

Testing backup copies regularly can help ensure the validity of the backup. Backup copies may be corrupted or incomplete, leading to data loss during data recovery. Therefore, you must perform periodic testing of backup copies to ensure that they are complete for successful restoration.

Perform backup copy testing in controlled environments to avoid harm to the production environment. The backup system should provide tools for testing backup copies. Ensure that the testing process is documented to ensure consistency and repeatability.

Regularly perform backup restoration before performing software or hardware upgrades or changes.


You've learned about cache data, the importance and benefits of backing up cache data, your options for backing up cache data in NCache, and best practices for backing up cache data.

The importance of backing up cache data cannot be overstated. NCache provides tools and comprehensive backup mechanisms for you to implement the best practices for backing up cache data.
