One of the most important tasks an administrator has is to set up and maintain storage resources and let users share files across the network. FreeNAS, a NAS server based on FreeBSD, makes implementing NAS simple. With FreeNAS, you can share files among the Windows, Mac OS, Linux, and Unix machines on your network. What’s more, FreeNAS provides incremental backups and supports LDAP user authentication, among its many features.
