For the last ten years, my small consulting company has used a readynas as the primary storage for files. I've heavily resisted using the cloud for primary storage... It is for encrypted backups only....
Unfortunately, tech moves on...everyone here uses Microsoft teams, Windows 10, and surface devices now...there is a push to integrate as much as possible into teams software.. One place for discussion, project management, CRM, calling, GitHub, Azure devops, etc....
Ideally teams would just be a bidirectional mirror of the readynas... But, teams isn't even friendly with onedrive... All major filestores have to be via sharepoint. I'm not seeing how to mirror sharepoint to readynas. I know a similar protocol is used, but realworld how would I get readynas mirroring sharepoint or integrating directly into teams...
One option is using another server to use readycloud to backup the sharepoint directories. Or, use readynas vault to backup directly to vault. However, I like knowing that there is a complete onsite backup of teams files in the nas...
Sharepoint is currently not supported on ReadyNAS only Onedrive and Onedrive for business. It will be a good additional feature, you may want to post it on the Ideas Exchange board.
