Hi Mike,
I suspect you are using CA ARCserve Central Host-Based VM Backup R16.0
to backup the virtual machines. If that’s the case I would advise you
to perform the following to resolve the issue:-
1) Verify you have completed all the prerequisite tasks that are
required before performing the install of Host-Based VM Backup, refer
the following URL for more information:
https://support.ca.com/cadocs/0/CA%20ARCserve%20Central%20Applications%20Enterprise%20Support%2016%200-ENU/Bookshelf_Files/HTML/hbug/ua_hb_prereq_tasks.htm
2) Verify if VMware VIX API 1.10.1 or later is installed in the
ARCserve D2D server which is configured as the backup proxy server.
3) Verify if R16.0 Update 3 is installed in the ARCserve D2D server
which is configured as the proxy server.
Let me know if the above steps doesnot help resolve the issue.
Regards,
Ajay Kumar
