I never had a tape drive so even though I know how to use linux, I still don’t know how to use a tape drive. I found this tutorial and it seem very easy after reading it. I am saving this for future reference.

The Software-RAID HOWTO
Jakob Østergaard jakob@unthought.net and Emilio Bueso bueso@vives.org
v1.1, 2004-06-03

——————————————————————————–
This HOWTO describes how to use Software RAID under Linux. It addresses a specific version of the Software RAID layer, namely the 0.90 RAID layer made by Ingo Molnar and others. This is the RAID layer that is the standard in Linux-2.4, and it is the version that is also used by Linux-2.2 kernels shipped from some vendors. The 0.90 RAID support is available as patches to Linux-2.0 and Linux-2.2, and is by many considered far more stable that the older RAID support already in those kernels.

Executive Summary
Postfix, written by Wietse Venema, is one of the most serious alternatives to Sendmail, along with Qmail and Exim. Because it is much more recent, it was built from the ground up to be as secure as possible. Postfix supports features such as ESMTP, ETRN (eg. two-way SMTP connections), LMTP (uses the LHLO command and expects to receive an ACK to check that the message is correctly delivered to each recipient), UUCP (to deliver mail between two servers with no access to the Net), AUTH to authenticate MATs at both ends (Cyrus-SASL supports AUTH), etc.
