 My question is we had an Idpa server in the data center and when we started the gsan service it take alot of time and still doesn't start. Alot of data has been backed up  and ican't find check point, what do you recommend? As a solution, is it possible to restore the backed-up data if we reinstall the avamar Server?    Thanks
IDPA Avama Server Service is down
