But if you don't have a lot of stuff to back up, or if the data is highly compressible, a standard tape drive should be fine. If redundancy is crucial, you may want to install a tape drive in each machine. This will reduce the need to backup across the network and in case one drive goes down, you can use another drive in the other machine to do a network backup. The downside to this method is the higher up-front cost. For our datacenter, we have a 22-slot DLT IV autoloader connected to a Windows 2000 machine (shh! I know, I know!!!) using Veritas Backup Exec. It works great for our Windows servers, but doesn't work with the BSD servers that run Samba. // Linh Pham // http://closedsrc.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
