One of the major benefits of Tally.Server 9 is Data Reliability. Tally.Server 9 ensures data consistency even in intense use environments and has zero impact from any abnormal client shutdown.
With Tally.Server 9, if you terminate the application, it will not affect any other instances and the data will always be safe and protected.
Similarly if there is any kind of abnormal activity at the client end, Tally.Server 9 will ensure that it is kept isolated to the client and neither the data on the server nor the activities of any other user gets impacted. This ensures that any loss of time due to system un-availability is minimized to close to zero.
