I have an external USB HDD and I like to keep it synchronised with my desktop for backup reasons. I find the easiest way to do this, is to use rsync:
> sudo apt-get install rsync > rsync -avu /source/ /dest/
> rysnc -avu /media/externaldisk/ /home/chris/diskbackup/
Will increment copy everything (ignoring older files) from /media/externaldisk to my /home/chris/diskbackup folder.
The options are:
- a – Archive mode – Will retain the folder/file properties, such as owner, permissions, etc.
- v – Verbose – Output the progress to the screen (so I know its still working)
- u – Update – Only update files that have a more recent file modified date.
