[gpfsug-discuss] backup and hsm with gpfs

[Alex Chekholko]

Hi Stefan,

Since you're using TSM with GPFS, are you following their current 
integration instructions?  My understanding is that what you want is a 
regular use case of TSM/GPFS backups.

For file system scans, I believe that the policy engine scales linearly 
with the number of nodes you run it on.  Can you add more storage nodes? 
  Or run your policy scans across more existing nodes?

Regards,
Alex
