estimatedFilesToTransfer

The number of files, objects, and directories that DataSync expects to transfer over the network. This value is calculated while DataSync prepares the transfer.

How this gets calculated depends primarily on your task’s transfer mode configuration:

• If TranserMode is set to CHANGED - The calculation is based on comparing the content of the source and destination locations and determining the difference that needs to be transferred. The difference can include:

• Anything that's added or modified at the source location.

• Anything that's in both locations and modified at the destination after an initial transfer (unless OverwriteMode is set to NEVER).

• (Basic task mode only) The number of items that DataSync expects to delete (if PreserveDeletedFiles is set to REMOVE).

• If TranserMode is set to ALL - The calculation is based only on the items that DataSync finds at the source location.
