Hello Shymaa,
SAP does not have an interface for BW unless BW is on HANA. One cannot compare Informatica NLS storage to SAP archiving Tools.
Informatica NLS is an interface, SAP has ADK just as mentioned by Gagan it is infrastructure to perform the archiving.
Informatica NLS uses the SAP ADK for archiving the data. The simple reason why does not have interface is that BW data needs to archiving in columnar databases.
But after accusation of Sybase IQ it is being used for BW archiving. If you have a plan for
BW on HANA it is better option.
Otherwise, you can try Informatica NLS or PBS NLS.
Please do reply for any queries.
Thanks,
Kolusu
