EMC NetWorker Exchange 2016 backup issue


Running the Exchange Server 2016 backup with the EMC NetWorker, I got the following log:

After some research I realize that the EMC NetWorker doesn’t support yet filesystem in ReFS format, only NTFS. Therefore, the filesystem format was the root cause.


In order to fix it, I performed the removal of all databases that had already been created and the DAG. I formatted the volumes in NTFS, and finally I created a new DAG and re-created the databases.

Note: If you don’t want to re-create DAG, be sure to change the “FileSystem” parameter that must be manually changed to NTFS.
