I think you have got to tell us a bit more about the issue you are trying 
to address.

Are you looking to get rid of tape altogether?   Or are you looking at 
alternatives as a primary backup, with a tape as secondary offsite copy?

Could you use the ability of FalconStor and NetApps to clone data 
cross-site, do you have the WAN bandwidth, or do you have just one site?

Are you just trying to fix slow clients?

What kind of DR do you have to provide? - e.g you may absolutely need 
tapes ready to send to a DR site, with picking lists per application to 
suit your recovery priorities.

Is EMC including Clariion or would using the EMC CDL mean supporting 
another disk array type?

Do your NetApps have SnapMirror/SnapVault/OSSV?

Do you have loads to spend? (you don't have to answer that...)

-----
People who do this (and we don't...yet) have very different ways even of 
using VTLs.  As Charles pointed out, NetApp and NBU 6 are designed to do 
some cool things.

Subject
[Veritas-bu] VTL vs. Disk based backups






We are looking at VTL technologies with EMC being the front leader. We are 
looking at upgrading to netbackup 6.0 Solaris 10 soon. My backup partner 
in crime disagree with the direction we should go. I think we should go 
with disk based backups and my partner want to go with VTL. Now since we 
do not have this in yet it is hard to look at both and "see" what is 
better. SO has anyone here also researching this subject and have their 
own opinion? We are a Netapp/EMC shop so the back disk is not the show 
stopper but the future of both technologies. Any care to share their 
views?
