Can anyone suggest a good open source/free backup software that works on CentOS?  I was reading through the manuals on how to back things up and it said do 1 of 2 things. Buy a 3^rd party software packages or make one from source. Well I have no clue how to do the 2^nd option and I don’t want to spend any money so I figured I would as you gurus. BTW I am newb so easier the software the better. Thanks.
