Not much from support yet. I get one email every couple of days, usually at night time. I usually reply straigh away but have to wait another day or 2 to have a reply!).
Anyway so far, I have been asked: "restart Vcenter management center", "do you have antivirus or/and firewall on the VM?", etc.
The issue is intermittent and not a huge issue. the job does not fail, it comes only with a warning. Once it happened when I manually ran the backup and I was in front the screen. It looked to me like the snapshot from Vmware to 3Par back to Vmware was the part that failed, and instead it only did a Vmware snapshot. However I could be wrong in what I observed.
Rurouni, do you had more chance with your case?
