I keep running into issues where newly set up backup jobs fail after a couple hours with the message "Storage Account for the backup plan is not specified".
Opening the job details and re-saving seems to resolve the issue. Is this a known bug?
Can you tell me what agent version you're running? The only reference that error I see in the system is back in version 7.2.2, and it was fixed in 7.2.2.1 . I'd probably recommend that you open a support case, but if you are running an older version of the agent, then upgrading an agent, at least on one endpoint with the issue, as a test might be worthwhile.
