Hello everyone!
I have a maintenance plan on sql server instance-1 and Workflow manager running on the 2nd instance with sharepoint 2013. The maintenance plan includes only one full backup task of 1st instance.
Everything is ok until I try to run my maintenance plan: then I can't start any workflows in my site collections. There are no errors/warnings in eventlogs. Nothing can help except restore from full server backup.
Any ideas?
