below ensures that multiple backups or streams can run concurrently whilst remaining within the concurrent file
limits for each D2D share.
Multiple servers, single stream backup
Multiple servers, multi-stream backup
Multiple servers, multiple single-stream backups
The table below shows the recommended maximum number of backup streams or jobs per share to ensure that
backups will not fail due to exceeding the maximum number of concurrently open files. Note however that
optimal performance may be achieved at a lower number of concurrent backup streams.
These values are based on standard ―file‖ backup using most major backup applications.
