Re: Generate backupset with more than one node on one volume?

I think we are using something similar.
We have external USB hard drive, and we are generating backupsets daily, but 
for one node and all filespaces. We have a service level contract with this 
customer (4 hours response time in case of disaster). Backup is over the 
internet.
So, instead going to data center (where we have our TSM server), and export 
data to laptop (I have tsm server on laptop) and drive to customer site, we 
just go there, unplug usb hard drive and still drive to customer site, but we 
save about 2 hours.
On site we restore from client, local backupset.

Before we go there I print:
Q backupset  and
Q volh t=backupset

Hi Mark

Why would the use of for example a USB connected drives be unusable?  Only 
thing you would have to know to restore a file device backupset(for 
example e:\backupset\00444333.vol) is the name of the sequential file. 

What I ment was, generate a separate backupset for each node on a 
removable media(on a USB disk for example, you could have multiple 
backupset volumes, which would eliminate the issue with having 1 400GB 
LTO-2 volume for each node). This would mean every node has it's own 
sequential file volume stored on your USB disk, which would make it 
possible to restore the node using a local backupset as long as you know 
which sequential volume associates with which node(stored in volhist.out, 
could also be written to the USB disk).

Am I missing something out, or was I wage in my description?

Best Regards

You could (theoretically) stack up backupsets by using the method by
using the method described by Daniel (use of DVD blanks, etc.), but
there would be no way to actually *use* such backupsets.

Also, collocation and storage pool parameters have nothing to do with
backupsets.
