For more information, see WAN Accelerator Sizing. The report allows you to assess historical growth of backup files and in case backup files grow too fast to decide whether to change job configuration to point it to another repository with larger capacity.

If you plan to use one target WAN accelerator with several source WAN accelerators, the specified amount of space will be allocated to every source WAN accelerator and the size of the global cache will increase proportionally. This report is useful for capacity planning purposes. The global cache size is specified per source WAN accelerator. In the Cache size field, specify the size for the global cache.When selecting a folder on the target WAN accelerator, make sure that there is enough space for storing global cache data. In the Folder field, specify a path to the folder in which service files (for source and target WAN accelerators) and global cache data (for target WAN accelerator) must be stored.To provide correct operation of WAN accelerators, we recommend that you allocate enough disk space for the global cache folder when adding a new WAN accelerator, no matter if the High bandwidth mode is enabled for it or not. Determine the dimensions of the structure that will fulfill your needs, along with the types of doors, windows and ventilation. But note that you can disable the High bandwidth mode and switch back to the Low bandwidth mode at any time, which will require to use the global cache. If both WAN accelerators (the source one and the target one) work in the High bandwidth mode, WAN acceleration does not use the global cache.
