Thanks for all of the great information.  This is kind of what I figured but I thought I better confirm.  Thanks!

Multiplexing is great for backup speeds but not so great for restore speeds as we found out at our first DR test years ago.

 

A proper backup strategy needs to include backup AND recovery time.   It doesn't do you any good to backup everything in 10 minutes if it takes you 10 months to restore.   And of course the restore time is only one part of the full recovery time.  

 

As mentioned by someone else on this list sometime back the DR SLA should include the complete recovery time which includes things such as getting tapes to the DR location, getting personnel to the DR location, getting equipment on line at the DR location, spinning tape, and post restore steps to actually make things usable (e.g. applying archive logs made after your last full DB backup).

My experience is that they run in the order which you start them unless multiple restores are multiplexed on a tape.

 

ie, you start jobs in order, 1, 2, 3, 4, 5.

 

if your multplex restore delay is set high enough, and images 2 and 4 are on the same tape, your restore order would be:

1

2 & 4 at once

3

5

Hello Netbackup Gurus,

 

     So I thought I would toss this out and get some feedback. 

 

     As we all know, Netbackup automatically sets restore jobs to have the highest priority when placed into the queue, barring any changes to the configuration, acts of the unknown and just plain weird stuff....  That being said, we had a issue during a disaster recovery scenario where we had multiple restores running and fighting for resources.  On top of that, we had to try and organize the restores in such a way that this restore runs first, followed by this one, than this one and so on (i.e. set a priority/order within the restore jobs).  My question is that in my digging on google and symantec's site, I can't seem to find anything that would let me change the priority/order of multiple restore jobs; has anyone run into this and/or devised a method and/or has some tips on how they handle restores during a disaster recovery scenario in order to set priorities on what gets what resources and thus done first?
