Veeam Backup & Replication backed up my Exchange 2010 server on Saturday night/Sunday morning. The backup reached 100% and began removing the snapshot. It's apparently been stuck at 95% since Sunday morning. The server is up and running and the delta files are slowly growing, not shrinking as I'd expect when committing the snapshot. I'm connected directly to the esx 3.5 host (no vCenter) and monitoring the file sizes via the datastore browser. I don't see any errors in the HP Insight Manager logs to indicate a hardware issue. Kernel latency looks nominal so I don't think it's an I/O issue. My fear is that I only have 300GB free on the 2TB datastore and my log volume on the Exchange server is not overly large. (I can turn on circular logging before that's an issue though) The problem is, this backup has never taken more than 15-20 minutes to remove a snapshot from this server. I've read that restarting the host can clear this up, but I'm scared to death I'm going to kill Exchange if I shut it down and reboot the host. Anyone have any ideas on what to try first? Everything is grayed out in Snapshot Manager so I can't delete all or create a new one.
