Please forgive the very basic question, but I have literally just starting using Linux (Centos) in the last week or so. I am using a standalone PC that is not networked, and as I will be downloading and generating a lot of data on this machine, I would like to regularly backup onto an external hard drive. Ideally I would like this to happen automatically as there will be other people using the machine. There seem to be many different ways of doing this, and I am getting a bit confused about the best method to use. Does anyone have an advice....?

Most basic method would be to use rsync.


rsync -aq /path/to/files /path/to/backup/dir

then you can set a cronjob to run it every night.

Here is a link to some info on cron if you need it:

I will give that a try. Thanks for the advice!
