I am not aware of any way to detect client based encryption via a server-based query. However, you can see this from a client-side CLI query (DSMC Q BACKUP), so there must be information somewhere that reflects this.
For anyone considering SUR pricing (capacity-based), you might consider looking at TSM-based deduplication instead of VTL-based deduplication, as your TB license requirements will be lower. Or at least, that's what I was told by an IBMer describing the SUR pricing model to me. Granted, you would need a more powerful TSM server, but you could offset that cost by purchasing disk less expensively than a VTL vendor would charge. ..Paul At 04:13 PM 11/28/2012, Harris, Chad wrote: >Thank you all for your sage advice. > >I am able to find the servers that are using compression, unfortunately >though, some of my client Admins have let it slip that they are not always >using compression when they are setting up encryption, despite our best >efforts to guide them that way. > >Anyone else know a way to find nodes only performing client encryption? > >Thanks again, >Chad > >-----Original Message----- >From: ADSM: Dist Stor Manager [mailto:ADSM-L@vm.marist.edu] On Behalf Of Bill >Boyer >Sent: Wednesday, November 28, 2012 12:01 PM >To: ADSM-L@vm.marist.edu >Subject: Re: [ADSM-L] Who is performing Client Based Encryption and Compression > >You could start by getting a list of nodes that are set to either >COMPRESSION=CLIENT or YES and those with DEDUPLICATION=CLIENTORSERVER.
