 Within a single copy activity run, ADF has built-in retry mechanism so it can handle a certain level of transient failures in the data stores or in the underlying network. 
 
-When doing binary copying from S3 to Blob and from S3 to ADLS Gen2, ADF automatically performs checkpointing.  If a copy activity run has failed or timed out, on a subsequent retry (make sure to retry count > 1), the copy resumes from the last failure point instead of starting from the beginning.

-Data partition is recommended especially when migrating more than 10 TB of data.  To partition the data, leverage the ‘prefix’ setting to filter the folders and files in Amazon S3 by name, and then each ADF copy job can copy one partition at a time.

 If any of the copy jobs fail due to network or data store transient issue, you can rerun the failed copy job to reload that specific partition again from AWS S3.  All other copy jobs loading other partitions will not be impacted.
