Of course, there are always man pages; and, for Solaris, docs.sun.com. Sun's online documentation is extensive, and it typically gives both detailed explanations and step by step for particular tasks. You want the System Administrator's collection for your version of Solaris. For example,
47.Using UFS Snapshots (Tasks) (System Administration Guide: Basic Administration) - Sun Microsystems.
I finally got my tapewriter script posted. You can find it, along with a sample conf file, an INSTALL.txt file, and a couple of man pages, at
Minimalist SysAdmin Tape backup script for Solaris 9 or 10. It is strictly for Solaris, using fssnap and ufsdump, and it is strictly for a single machine, using either a local or remote tape drive. It's a pretty good working example, but I wouldn't try to make more than that of it.
Let me know how it goes.
