We're getting a new File Server and we're looking at Windows 2000 Server but also considering Linux (RedHat 7.2) as a cheaper alternative. We have a few concerns about how to handle file permissions for NT4.0/Windows2000 users (so they can work with the files). We're getting the Linux from DELL (preinstalled)...but need help with permissions and also allowing Veritas Backup Exec to backup the files. Anybody want to offer some tips on this and/or direct us to resources?
