For the cache capacity, you can set a value from "10 % of the datastore capacity (20 GB minimum)" to the "size of a virtual disk connected to the virtual machine in which this product is running - 1 MB".
It is recommended that you set the cache capacity to 50 % of the datastore capacity. If a short restore time is required, set the value with the same capacity as the datastore capacity.
Point
The cache area is secured in a virtual disk that is connected to the virtual machine in which this product is running. Therefore, you must prepare a virtual disk that is greater than or equal to the "cache capacity to be set + 1 MB".
You can also assign multiple virtual disks to the cache area.
