Any changes made to the queue location will not take effect until the Storage

Select a location on a non-clustered volume that will have minimal impact on
the operating system and applications being protected. For best results and
reliability, this should be a dedicated, non-boot volume. The disk queue
should not be on the same physical or logical volume as the data being
replicated. Also, for best results, select a location that is on a different volume
as the location of the Windows pagefile.
Although the read/write ratio on queue files will be 1:1, optimizing the disk for
write activity will benefit performance because the writes will typically be
occurring when the server is under a high load, and more reads will be
occurring after the load is reduced. Accordingly, use a standalone disk,
mirrored (RAID 1) or non-parity striped (RAID 0) RAID set, and allocate more
I/O adapter cache memory to writes for best performance. A RAID 5 array will
