The number of configurable snapshots that are supported for SSR in a file server is 200. SSR (Snapshot-based Replication) is a feature that allows administrators to replicate snapshots of shares or exports from one file server to another file server on a different cluster or site for disaster recovery purposes. SSR can be configured with various parameters, such as replication frequency, replication status, replication mode, etc. SSR supports up to 200 configurable snapshots per share or export in a file server. References: Nutanix Files Administration Guide, page 81; Nutanix Files Solution Guide, page 9

Nutanix Files provides a built-in ransomware prevention feature that allows administrators to block malicious file signatures from being written to the file system. However, this feature has a limit of 300 signatures per share or export. If the list of malicious file signatures to block is greater than 300, a third-party solution is recommended2

Neither File Analytics nor Data Lens supports signature-based ransomware prevention with a large list of malicious file signatures (300+). Signature-based blocking requires a dedicated security solution with a robust signature database, which third-party tools are designed to handle. Nutanix Files supports integration with such tools, making a third-party solution the best choice for this requirement.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“For advanced ransomware prevention requiring signature-based blocking, such as when the list of malicious file signatures exceeds 300, Nutanix Files supports integration with third-party security solutions. These solutions can handle large signature databases and perform file scanning/blocking at scale, complementing the behavioral detection capabilities of File Analytics and Data Lens.”

The Files feature that the administrator should enable to ensure the sessions will auto-reconnect in such events is Durable File Handles. Durable File Handles is a feature that allows SMB clients to reconnect to a file server after a temporary network disruption or a client sleep state without losing the handle to the open file. Durable File Handles can improve the user experience and reduce the risk of data loss or corruption. Durable File Handles can be enabled for each share in the Files Console. References: Nutanix Files Administration Guide, page 76; Nutanix Files Solution Guide, page 10

Self-Service Restore (SSR) is a feature that allows individual users to restore files and folders hosted in Files without requiring administrator intervention. SSR can be enabled on a per-share or per-export basis, and users can access the snapshots of their data through a web portal or a Windows client application1.
