I had to move a LOT of data from an old linux server to a new one. As both systems had four disks configured as a software RAID-5, I couldn’t connect all drives to one computer. I was simply out of ports to plug the drives into. \ud83d\ude42<\/p>\n
I wanted to use Simply copying everything with rsync wasn’t a success, the underlying SSH worked well, but the speed was by far too slow (~20MB\/s). The „old“ machine wasn’t simply powerful enough to handle RAID-5, SSH and rsync with maximum performance at the same time.<\/p>\n Using a differenct cyper ( In the config file and the commands below you must change „hostname“ to the name of the „server“ and the „sharename“ accordingly.
