Snapshot is a unique technology invented by NetApp that provides basic features for internal backup and recovery of data. This feature is built into the NetApp storage OS, unlike other storage systems that may require separate products or have less efficient snapshots.
NetApp snapshots are space-efficient and spontaneous. All of the data protection technologies offered by NetApp rely on this Snapshot.
Snapshot is basically the base of the backup and recovery. So, the products built around it are more attractive for the customer because, in the end, customers would like to take advantage of the backup and recovery offered by NetApp.
NetApp Snapshot's point-in-time copy functionality
By definition, a Snapshot is a point-in-time copy of data. This means that whenever you schedule or take a snapshot on NetApp, it is a copy of the data at that specific moment.
For example, you can take a backup of your data at 9 AM, and then have another snapshot at 1 PM. This is a standard model, and you will have your data's copy available on the cloud. Whenever you want to restore it, it will be restored based on the chosen snapshot.
The restore process is very fast, and the resources are easy to configure. Also, depending on the application, some require specific agents to take a snapshot. For instance, if you are taking a snapshot of an Oracle database, you need to use the agent from Oracle to take a snapshot. Similarly, if you are taking a snapshot of Microsoft SQL data, you need to use the Microsoft Shadow Copy Service along with Snapshot.
Most importantly, snapshots are space-efficient and consistent across all applications. This ensures that the data and backups will be available when needed.
Another technology used by NetApp is SnapLock, which integrates with Snapshot for autonomous ransomware protection and secure backups. SnapLock locks the backup data so that no one, including attackers, can change or interrupt the snapshot. This is another layer of protection provided by NetApp.
Compliance with data regulations:
NetApp also provides a product for regulatory compliance. This addresses requirements like global backups, remote site backups, and redundancy (e.g., n+1 or n+1+1), or a three-tier approach with backups on the storage system, another storage system, and tape or another medium.
This product is available to address compliance issues imposed by regulations and legal liabilities. I don't know the exact name, but I believe it's NetApp Compliance or something similar.
For example, if the customer is a bank, they may have compliance issues set by the Central Bank that require to save the data on three different tiers.
Keeping up with AI:
To my knowledge, there is no direct relation with AI, but indirectly, there is an interrelation.
Snapshot is entirely focused on backup and recovery. It's used indirectly to back up and restore data.
