Uhm.. this is interesting..

What is my opinion?

I think TSM DB won't be a problem.. I think your main problem will be to do an 
incremental backup or in case of backup image is the individual file restore.

With your information ..

I will think in a GPFS Cluster.. and copy the files through several cluster 
nodes in parallel. You can even use TSM for Space Management..

More, FlashCopy will provide you a copy of data. You will need more space but 
it 
will be quickly and you will get the data online in short time. The problem is 
if you want to restore one file you need to mount the flashcopy in other 
machine 
and restoring the file. But the main advantage in case of  machine fails and 
you 
need to restore the whole scenario you can restore the files more or less 
quickly. 


More.. I will try to launched several sessions in parallel against TSM Server 
6.2 ( of course) you will can divide by unit or filesystem. and testing if it 
will be a solution valid for you

Finally NAS solution could solve some previous issues.

Asunto: TSM Archiving 50tb data with millions of files

Need to archive 50tb of data with millions of files, here is the caveat, tsm db 
at 220gb, planning on upgrading from 5.5 to 6.2 in the near future, but 
currently waiting for newer hardware, how would one accomplish this without 
causing too much db bloat? Any ideas would be greatly appreciated.

Thanks
