In the last days i lost some (non critical) data cause i had forgot to install rsnapshot in my laptop. I was without network for a couple of hours and there was nothing on TV. So … i’ve played with bash and made a bash script to backup some directories with a snapshot logic.
The bash script is really simple and straight-forward without any difficult parts. So you can easily configure it, to serve your needs.
