Open Source Backup Software What Is A Good, Backup Software For Linux?

What is a good, backup software for linux? - open source backup software

We have 3 Linux (RedHat ES3)

We believe we want commercial software, but open-source software is not excluded.

In any case, want a central management interface, so you / can backup / restore, from a single computer / tape drive.

I want something DR bare-metal recovery capabilities.

Easy installation and administration, is much better - there are (special benefits and very good documentation to support the open source community as a good option), would be willing to offer some simple "up - but most of those who have something that is often much time to configure and maintain want.

It is not necessary, but .. It might actually decide to DVD DL for our backups. If we did, it would be nice if the software has a Windows interface for management, so that the disc will be engraved on the Windows machine with the DL DVD.

Whatever - interested to hear what people from different options that there are too!
