About the Local Storage Tool
The Local Storage Tool must be enabled by your service provider from the DS-System. Your service provider provides this tool from DS-System and should form a part of your service agreement.
Local storage behaves differently for backup sets assigned to a retention rule:
Without Retention: Local storage keeps a copy of the latest generation of the backup set files (as well as online, offsite at the DS-System).
With Retention: The same number of generations are backed up to local storage as are on DS-System. Make sure there is enough space in the local storage buffer, and perform the “Enforce Retention” process regularly.
NOTE:  In both cases, when a new backup session occurs and an existing generation of a file is replaced by a new one, the deletion of the old generation will take place after the new one is successfully saved on the local storage. This means there must be enough free space on the Local Storage to accommodate both generations.
The Set Properties Options tab offers the following options:
Save on Local Storage: Enables local storage for the backup set.
Transmission cache on Local Storage: See “About the local storage cache”.
IMPORTANT:  The local storage path is shared by both the local storage tool and the local storage cache. Make sure that the location that you select as the local storage path offers sufficient capacity to accommodate the requirements for both functions. FAT and FAT32 volumes are not supported as local storage locations.
