Your NAS permissions are probably a mess, and a single flat share fixes it

NAS permission setups frequently become overly complex due to nested folder structures, overlapping user groups, and conflicting ACLs. The recommended approach is to use a small number of top-level shares (one per data type: backups, media, security footage, etc.) rather than deeply nested folders with granular per-folder permissions. Permissions should be managed at the share level, using groups instead of individual users, making it easy to grant or revoke access. Documenting the permissions structure is also emphasized as a key practice for long-term maintainability.
