SMB compression help

We migrated to Windows server 2022 and are deploying new infrastructure and management approved server 2025. Our total unstructured data goes beyond 3.5PB across all shares. We normally use Robocopy or goodsync but goodsync does not support SMB compression which we have enabled on the servers. Robocopy performs much better but management wants reports that data copied perfectly due to some compliance. Ideally, we need an email with the log, support long path, ability to run as a service, and easy way to manage all the jobs. The latter three options are supported by many data replication utilities but no one supports SMB compression and no plans to. Any recommendations?

    Hello,

    You can request that SMB compression is attempted for particular files using robocopy or xcopy.

    Open a CMD prompt or PowerShell command prompt.

    Copy with the /COMPRESS flag. For example:

    ROBOCOPY c:\hypervdisks \hypervcluster21.corp.contoso.com\disks$ *.vhdx /COMPRESS

    Note:If you want File Explorer, third party copy tools, or applications to use compression, map drives with compression, enable compression on shares, or set SMB clients to always compress.
