Hi all ,  
In order to take snapshot of index whose size is around 2 TB , how should i set {

1. Chunk size
2. `max_restore_bytes_per_sec`
3. `max_snapshot_bytes_per_sec`  
}  
these parameters to get optimal and maximum performance ?  
Keeping in mind my repository is connected to azure blob to save my snapshots
4. Any estimate of how much time it will take while taking the snapshot with max settings ?

Thanks ,  
Hope to get a response !!
