Dear komal,
There's an excellent article about
"Backing up Linux Machines" by
Gentoo C.E.O Daniel Robbins
on the IBM developerworks site.
It's very comprehensive and uses a utility called "star" as ref. which according to daniel is better than tar and also works on various filesystems unlike dump.
There's also detail abt rewind and norewind tapes.
If you want the pdf you can mail me offline.
bye rgds
