### --server-side-across-configs ###
|
||||
|
||||
Allow server-side operations (e.g. copy or move) to work across
|
||||
different configurations.
|
||||
|
||||
This can be useful if you wish to do a server-side copy or move
|
||||
between two remotes which use the same backend but are configured
|
||||
differently.
|
||||
|
||||
Note that this isn't enabled by default because it isn't easy for
|
||||
rclone to tell if it will work between any two configurations.
|
||||
|
||||
### --size-only ###
|
||||
|
||||
Normally rclone will look at modification time and size of files to
