Questions on backint.

Hello,

I have a few question on the SAP Hana Database backint development. Can you please me some advices on below questions?

1. In the backup, is it always one PIPE per backint? Will Hana use FILE instead of PIPE in the backup?
   Will one backint include multiple pipe/FILE?
2. In the backup, is the pipe name unique in the multi-mode environment?
3. In the backup, Is there sequence when launching backint? Eg, one by one or multiple
   backint together.
4. In the multi-node backup, are the parameters of backint specific to the node? eg: the
   number of objects are the number of object on the specific node, but not the
   number of objects on the multi-node environment
5. How to know the status/end of backup? By polling on the HANA DB? or by tracking the number of objects in the backing?

Thanks,

Bill.
