Data Written Size
The Data Written size shown in the several dialog boxes, (for example, Job Details, Data on Media, etc) and summaries (for example, Data Management Job History) is the size of the data written by Commvault software to the StoreOnce client and must not be confused with the size of data transferred over the network.
Data Immutability Support
Data Immutability is not supported for HPE StoreOnce Catalyst libraries.
