Hi,
Exchange GRT 2013 backup was configured recently.
GRT backups are taking a long time to get completed. It takes almost 12 hours for a successful completion.
Backups are written on VNX disk.
200GB DB:
waited for full buffer 344334 times, delayed 2600184 times
There are times that jobs running in this media server get completed at 200MB/S
Detailed status for a 6GB exchange DB:

Full DB GRT backup is taking too much time compared to incremental brick level backup. Is there anyway to increase the speed of this GRT backup?
