Note: Druva also supports the backup of files and folders on the non-VSS partitions such as FAT, FAT32, and exFAT. 

Note: For File servers running on Windows operating system, Hybrid Workloads agent interacts with Volume Shadow Copy Service to back up your data. Druva recommends that you use the Microsoft Native VSS provider to successfully back up your data. If you are using any third-party VSS provider, you must configure Hybrid Workloads agents to recognize this third-party VSS provider. For more information, see Configure Hybrid Workloads agent to recognize a VSS provider.

  • For File server running on Linux operating system, Hybrid Workloads agent performs the live files and folder scan.
  • For Windows UNC shares of File server, Hybrid Workloads agent uses CIFS and SMB.
  • For Linux mounted shares of File server, Hybrid Workloads agent uses NFS.

Hardware requirements

  • CPU: 3 CPUs (Minimum)

Network requirements

Druva communicates with your File servers to backup and restores the data from your File servers. This communication happens through ports and protocols that are secure for communication and transition of data.

Druva uses Transport Layer Security (TLS) protocol for establishing a connection and initiating communication between Druva components and your File servers.

The following diagram depicts the ports and communication protocols that are used by Druva for secure connection and communication during the backup and restore operations.
