System Requirements

You can install WCN on a computer that meets these minimum system requirements:

  • PC with a 64-bit (x64) processor
    Note:  The WCN client makes API calls to interact with the Wasabi Cloud. Depending on the number of sources mapped through the WCN client, the configuration of global settings, and the policies attached to the sources, the volume of API calls may increase. Poor CPU performance can adversely impact API performance.
  • 64-bit Microsoft Windows® 7/Server 2008 R2/Windows® 8/Server 2012/Server 2012 R2/Windows® 10/Server 2016/Server 2019/Windows® 11/Server 2022
    Important: Microsoft Windows® 7/Server 2008 R2 computers must run at least Service Pack 1 and have the KB976932 and the KB3033929 security updates installed.
  • 4 GB of physical RAM (at the minimum)
  • 60 MB of available hard disk space for installation (at a minimum)
    Note: WCN maintains a database in the product installation folder to track the files it manages. The database size is directly proportional to the number of managed files. For example, if WCN manages 1 million files, the database size will be approximately 100 MB. Insufficient free space for the database will hinder WCN functionality.
  • Microsoft .NET Framework 4.8 installed
  • The firewall on the computer responsible for managing inbound and outbound network traffic must not impede the transmission of data via the following TCP ports:
    • 80 - outbound rule only (for communication with object storage target over HTTP connection)
    • 443 - outbound rule only (for SaaS activation and/or communication with object storage target over HTTPS)
      Note: The Wasabisys domain must be accessible through the network firewall, and the application should have the capability to connect to the license server and object storage endpoints. Ensure the cloudnas.wasabisys.com domain is whitelisted, which is required to use a licensed version of Wasabi Cloud NAS software.
    • 445 - outbound rule only (for communication with SMB network share target)

Source Storage Requirements

WCN supports the following sources:

  • NTFS or ReFS volume, mounted on the computer running WCN as a local volume with Read & Write permissions and on which the System account is granted Full Control
    You can use the whole volume or just a folder as a source. You cannot use a folder as a source if its parent folder is already paired with a bucket (i.e., is set as a source itself).
  • SMB or NFS share accessible on the same network as the computer, running WCN and a dedicated account (Active Directory domain or local account on the NAS appliance), which has Full Control (on Windows) or Read & Write permissions (on Linux) over each share, which will be used as a source
    To use network storage as a source, for each network share, create a control folder located on a locally mounted volume on the WCN computer. The control folder To use network storage as a source, create a control folder on a locally mounted volume of the WCN computer for each network share. The control folder functions like a shadow copy folder, used solely for storing stub file copies of the actual files on the network share, and it facilitates data retrieval from the share when Space Reclaiming is enabled. For details about configuring a NAS source, refer to NAS Source Prerequisites and Setup.is similar to a shadow copy folder, which is used only for storing stub file copies of the actual files on the network share and facilitates the retrieval of data from the network share if you enable Space Reclaiming. For details about configuring a NAS source, refer to NAS Source Prerequisites and Setup.

All sources can contain data prior to pairing them with their respective bucket.
