How do I use Wasabi File Acceleration (WFA)?


Wasabi enterprise customers* now have an option of transferring files to and from Wasabi’s hot cloud storage via the Wasabi File Acceleration solution. The use of file acceleration technology to speed up file transfers is common in several industries.  Wasabi jointly with a technology alliance partner FileCatalyst, are introducing a new offering with this ability.

*The use of the capability is generally best suited for customers that have 100 TB or more in Wasabi storage and have sufficient network connectivity to use the feature.  Please contact Wasabi Sales for additional information. 

The Wasabi File Acceleration (WFA) utilizes the following reference topology:


The function of the element’s solution are described below:

  • Wasabi HotFolder Application:  This is a software client that you install on your Mac or Windows platform.  This is the only product that you need to install in your local environment
  • Wasabi File Acceleration Server: This is server software that terminates the FileCatalyst protocol and is hosted on Wasabi-associated compute resources.  This server software is preconfigured and you do not need to make any changes to this configuration.
  • Wasabi Storage:  This is the Wasabi hot cloud storage service.  You can use your standard Wasabi account username & password when using this solution.

Once you have installed the appropriate Wasabi HotFolder for your host platform, please contact Wasabi so that we can set up an account for you in our WFA Server instance. As part of this setup, we will need the following information:

  • Email address associated with Wasabi
  • Access & Secret keys
  • Bucket name for HotFolder association

This is so that the WFA Server instance can send the uploaded files to your designed Wasabi storage bucket.  

Note: You do have the option of setting up a sub-user and associated bucket and bucket policies so that you do not need to provide the API keys for your root account.  The procedure for this configuration is provided below in the Appendix of this document. If you want to use the sub-user approach, please set this up before you contact Wasabi as we will need the API key info from this procedure.

If your needs require multiple WFA instances but would like to write the content to single Wasabi account in various buckets, Review the following link to help you configure the Wasabi account and create user separation between your WFA users.


In this above architecture, each HotFolder Client will have their own private bucket, creating IAM policy on Wasabi will allow you to create user separation and keep data between each sub-user private from other users.

To achieve the above structure, follow steps below in the same order:

  • Create sub-users
  • Associated S3 API keys for each sub-user
  • Associate a IAM policy for each sub-user which restricts buckets being exposed to other sub-users
  • Once above steps have been achieved – steps outlined from 1 thru 16 in this document will need to be performed for each HotFolder Client instance.
