Error during Datasync Transfer

Question

What should I do if my Datasync task stops due to some error without completing the transfer,i..e., without transferring all the objects from an S3 bucket in Account A to an S3 bucket in Account B?
Will it continue to transfer the remaining objects if I start the task again or will it transfer all the objects from the start?

Accepted Answer

Hi,  from Datasync FAQ:

https://aws.amazon.com/datasync/faqs/

```
Q: What happens if an AWS DataSync task is interrupted?

A: If a task is interrupted, for instance, if the network connection 
goes down or the AWS DataSync agent is restarted, the next run 
of the task will transfer missing files, and the data will be complete 
and consistent at the end of this run. Each time a task is started it performs 
an incremental copy, transferring only the changes from the source to 
the destination.
```
So, as expected only missing or updates files will be transferred when you restart datasync

Hope it helps!
