I want to recover data from our web and app server (420-R , running solaris 8 ) onto a different server of same architecture (similar disks) located at a different place to do a disaster recovery test. The web server has been mirrored using solstice disk suite (meta disk) and app server has veritas volume manager and filesystem installed. Is it possible to recover data without having veritas license on a different machine? Will disk mirroring with solstice disk suite create problem during recovery? can anyone give some suggestion/precaution to be taken on that ?

You'll be fine with ODS, vxvm and vxfs do need a license, but veritas will probably give you a temporary one if you ask politely.

How are you backing up the data?

I need few tips on recovery. I plan to backup data on tape. I am planning to backup data of different mount points like / , /var/, /apps which are in veritas volume group onto different tapes and recover it on different machine. I already got temporary keys from veritas . Can anyone tell how I should go about doing it ?

It's just like any other backup/restore.  Choose the backup programme you prefer and stick with it.  Try to avoid restoring the OS filesystems, /, /var, etc., and static executables which I guess you keep in /apps.

Set your DR boxes up as imitations of the production machines, including volumes, mount points, and application configs,.  Then all you need do is restore the applications data areas.  That is, regard your DR boxes as "disconnected" nodes in a cluster, think about what you would need to transfer between machines in for example, a VCS cluster, and just restore that.  If you set up a VPN between your DR site and main site, one could even move the machines/applications IP too.

This is how the df -k output looks like. The root partition is in rootvol group  and my applications /app is in apps volume group. How do i restore rootvol group on the other mnachine. Restoring apps alone would be easy since I can have install basic os on the machine and recover the apps volume group but here even the root is in rootvol. Should I try to install basic OS on the other machine and try to recover all /, /usr/, /var and /apps ? Will it go smooth?

There are lot of ifs and buts. Could anyone clarify me on this ?
