Time Machine stopped working with Drobo FS
Have used Drobo FS as a Time Machine backup for several years. Currently running Drobo Dashboard 2.8.1, firmware 1.2.7tdz, and Mac OS X 10.11.5. Looks like update to 10.11.5 caused Time Machine to self destruct. Cannot detect Drobo. Connected to Drobo with Mac Book Pro running 10.11.4. Looks like Time Machine files have been flagged .purgeable. Drobo support basically blew me off. Any suggestions?
