[gpfsug-discuss] IBM Spectrum Scale transparent cloud tiering

[Marc A Kaplan]

>From the press release: 
   "And Spectrum Scale extends its policy-driven targeting, migration, 
encryption and unified access to the data in the cloud-scale object 
storage."

Take care with the "encryption" claim.  Spectrum Scale can encrypt your 
data as it is stored onto Spectrum Scale controlled disks (NSDs)...

I could be wrong, but last I looked, there was no way to export or backup 
the encrypted data blocks.  Naturally when you cp, dd, tar, a file to 
another system you
are getting the file data "in the clear". 

OTOH, of course if you FlashCopy a volume that is holding an encrypted 
Spectrum Scale file system, then those data blocks are encrypted.
