my first thought is that new datastores were created in vcenter and the server moved.

go to administration

find your proxies

right click edit

see if any datastores are NOT checked

check them ( or select all) and ok

do that to all the proxies

and try again.

That of course depends on how you use your proxies and backups

some people have specific proxies for specific datastores.

do what is proper for your policy.

JH - I've played with selecting all or specific datastores for the proxy clients. Within the edit dialog it indicates that the datastores are selected and accessible. Thx SC
