About the local storage cache
The local storage cache is an option that you can configure for a backup set to define a disk location for the temporary storage of backup data if the connection to DS-System is lost while a backup is in progress and all configured retries fail. Once DS-Client reestablishes the connection, it sends the data in the local storage cache to the DS-System.
When sending data to the local storage cache, DS-Client processes the data from the source and saves the data as a full backup in a compressed and encrypted format on the local storage cache. If the connection from DS-Client to the DS-System is maintained throughout the entire backup activity, the local storage cache is not used.
IMPORTANT: By default, the local storage cache location is the same as the local storage path. Whatever path you select, ensure it has sufficient capacity to store the backup data. When used, the local storage cache supports the total amount of data that needs to be master processed and backed up in a compressed and encrypted format for a backup set.
