(forgive, I forgot to add the word "SUMMARY" in the subject.
Here goes again...)

My orignial query...

>I'm trying to find a way to have my Sun Unix server backup

>I currently run backups over the network from my
>unix backup server by executing "rsh $REMOTEHSOT ufsdump".
>With the use of Hummingbird's Maestro for NT I have RPC
>and NFS services on the NT... but no dump command... the

>server to backup an NFS mounted partition, and I don't

>Any suggestions?


Apparently there aren't any unix dump utilities that will work on the NT filesystem (apparently because the dump utility is heavily implemented around a unix file system). There are, however, alternatives...

There were several suggestions to use Legato/Networker. It appears you can get NT licenses.

Let me say simply that I have some philisophical (some say irrational...) difficulties with proprietary backup software and get a big warm fuzzy knowing that utilities like dump, tar, cpio, and dd will long outlive most proprietary solutions. I like to know that I can restore a dump or tar archive to any unix machine in the world, whether it's a Sun, an HP, a PC, ... you name it ... and I won't be told by the restore software that this product is not currently licensed for this machine! :-{} Grrrr! Okay, enough said.

There were a ton of suggestions to use Samba. Samba comes with a tar utility specifically designed for doing backups of your PC from your unix server. It's fast, efficient, and free! A very popular solution!

A number of people pointed out that while you can't "dump" an NFS partition, you can "tar" and "cpio" these remotely mounted partitions. While "cpio" has built-in provisions for incremental archiving it is a little cryptic and has somewhat fallen out of use these days. Sun's version of tar (pretty standard) provides no incremental archiving functionality. GNU's tar DOES provide incremental archiving!

My Solution... As I noted in the original query, I'm running Hummingbird's Maestro NFS server on the NT machines. I want to leverage that investment and besides, I just like NFS! That combined with GNU tar is the way to go.

I'll add some code to my perl backup script to gnu tar archive the NT PCs over automounted NT partitions, somthing roughly like...

"tar -cvf /dev/rmt/0n /net/NT#1/c" ... you get the idea.

Talk's cheap. I need to go implement it now!
