When data from Silo Storage is restored, the Silos are retrieved to the primary media. By default, the Silos are retrieved to the original mount path from which the data was migrated to silo storage. However, during a restore, if the original mount path does not have enough space, the Silos are automatically copied to any other mount path with sufficient space available in the library.
To ensure that a mount path with sufficient space is available in the library at all times, you can have a dedicated mount path that is reserved for Silo restore operations only. When reserved for Silo restores, the number of data writers to the mount path is set to zero and this prevents the mount path from being used for regular backup operations.
When a reserved mount path is available, then all Silo restore operations on the library are run to the mount path by default. It is recommended that the storage capacity on this mount path is equivalent to the size of an average Silo.
