Frequently asked questions
What is the difference between
copy command is a simple transferring operation, it scans the source and attempts to transfer every single file/blob. The supported source/destination pairs are listed in the help message of the tool. On the other hand,

copy is definitely the right command, since it offers much better performance.
sync, last modified times are used to determine whether to transfer the same file present at both the source and the destination. If the use case is to incrementally transfer data
sync is the better choice, since only the modified/missing files are transferred.
