Hi,

I'm testing out using DP's Dedupe stores for the first time on a standalone VM. I've given the VM an E drive pointing to a specific VMware datastore, on a standalone backup only storage array. I then used DP 23.4 panels to create a new Dedupe store, and it worked just fine, test backups ran, and some scheduled. But then I noticed the media delete jobs which kick in to delete old backups was not working due to immutability settings on the Dedupe Store:

Immutability period of the medium abc is not completed

Reading up on immutability the default is 10 days for a new Dedupe Store. But going through the panels again in the DP GUI I could not see anywhere where I could have set this timeframe. Checking the DPDUtils commands on the VM itself, there are no commands to change an existing Dedupe Store immutability settings. Is my only option to delete the test store, and then use the DPDUtils command to create the store with the -i setting for immutability, and then the panels to point to the store and use it? 

Thanks,

Andy
