Hi there Anshal
Thanks for using QandA platform
I would say the Best practice is to copy the data into Azure Blob Storage first, validate it, and then move it to the bronze layer.
Implement steps lik checksum verification, file count and size matching, sample data validation, and metadata consistency checks.
The typical duration for the entire Databox Heavy process is 10-20 days, including 2-5 days for preparation, 3-7 days for shipping, and 2-5 days for data upload. my guess.
If this helps kindly accept the response thanks much.
