Locally backup your data with rsync              After 1 year later HDD data transfer speed was 70~100 kbps . How should you do with useless HDD ?    I try with following command: rsync -r -t -v -progress --ignore-existing -s [ source] [ destination ] rsync                        a fast, versatile, remote (and local) file-copying tool -r, --recursive This tells rsync to copy directories recursively. See also --dirs ( -d ). Beginning with rsync 3.0.0, the recursive algorithm used is now an incremental scan that uses much less memory than before and begins the transfer after the scanning of the first few directories have been completed. This incremental scan only affects our recursion algorithm, and does not change a non-recursive transfer. It is also only possible when both ends of the transfer are at least version 3.0.0. Some options require rsync to know the full file list, so these options disable the incremental recursion
