[Samba] Re: nt->samba backup suggestions

[Sykora, Dale]

Jacob,
	Thanks for the info! As you suggested, I will look into the inner working of smbtar.  I just joined the mailing list today.  I'll research the topics you mentioned.  I also need to brush up on multiple ethernet and tape devices as my experience is lacking.  My big concern right now is if my gameplan is reasonable or if I should consider another approach.  

Thanks,  
 
Dale
