Easy and cheaper Database software

I am looking for a back up database that I can use to store my record. But I need a solution which is secure and lets me use my files easily

I have been given many suggestions from friends and relatives. I have weighed my options and have come down to the conclusion of getting the services of CloudBacko Pro.

But I want to get suggestions from the extended world as well before I take the final call. Please give you recommendations and give me benefits and limitations of your choice as well.

Thanks for your help in advance.

Do it need to be a cloud storage ?
Can’t you just use an external harddrive and for example the BackInTime Software that creates incremental backups of your important data.
The drive can be of course encrypted for best security. There are solutions for this on linux with LUKS and Encfs. I personally recommend LUKS here.
