Since upgrading to 9.5 update 3, we are getting this error when trying to access our data domain devices:
Failed to call RPC function DDBoostSetCreds
Support fixed this once by restarting Veeam services and running the VeeamPluginsHostX64 application from C:\Program Files (x86)\Veeam\Backup Transport\x64
It was fine for 2 days then all of our jobs failed last night with the same error. Any ideas?
