Linux as a file/backup server?

[nucleus]

Hi,

I have a Windows computer which serves as a file server.

I access it through a network share, all my data is on HDD1, and I have a simple batch file running as a shcheduled task every night which copies any differences from HDD1 to HDD2

Now I want to install Linux on that computer. Setting up sharing is easy nowadays on Linux, no problem there.

But how do I automate the copying process between the 2 hard disks? Only the changes must be copied, and it must be done automatically.

Can anyone help me?

Thanks

Well rsync and its front-ends (GUIs) are a standard choice for Linux backups (incremental)

--just do a search on the backup programs via Mint package manager, and see what is available, there is a link to the software web site as well as a screenshot or description of the program..

I second rsync. It is an excellent shell command. It will copy only differences.
For example,
sudo rsync -vax /hdd1_path/ /hdd2_path/

And you can make this command execute periodically using cron. You just put an entry in crontab as the user who will run the command. So you probably want root to do the copying (?) and so you would become root then edit contab. See http://www.linuxhelp.net/guides/cron/.
