“It is often the case that an sftp transfer gets
interrupted for one reason or another, resulting to partially
transferred files. This can be annoying, especially in the case of
large file transfers. Even though the Linux version of the sftp
client doesn’t offer a direct way to resume an interrupted
transfer, doing so is quite simple by using common shell tools, as
long as you are able to login to the remote server through a
console. Assuming that you are transferring data.zip from
source_server to target_server and the transfer was interrupted,
you can do the following:“Connect to target_server using ssh, since you will be required
to perform some operations there. Navigate to the directory
containing the partially transferred file (also called
data.zip)”
