Any GPL/free backup or imaging software for distribution?

I work for a tech company that sells computer equipment to the trade, we'd like to provide complimentary data security tools to our end users, not the bloatware that come with a lot of computers [which manufacturers get paid to put in, as it leads to a purchase of full featured version].

We'd like to provide added value, by allowing users to download the software and install quickly and more precisely for free.

It will be a sort of data security bundle, but what we don't want to do is provide links to pre-existing software bundles on the internet and claim it as our own, because that would be really tacky.

I'm looking for

1. quality tools
2. something that we can have distribution license to place on our web server.
3. Possibly put onto CD with other security bundles, e.g. backup software, antivirus software, anti malware software.

Any recommendations?

 

Maybe Areca Backup?

 

Or Backula......?
