IMHO, all tools work and are a reasonable piece of a solution, and none are complete.
Use any tools you feel comfortable with, but my suggestion is to use the old 3-2-1-0 approach. 3 copies of data 2 different media 1 copy offsite 0 test restores regularly Yes those are vague, but I have been caught by all of them at some point in my career And the numbers are MINIMUMS, not recommended levels. Testing regularly in a perfect world would be a complete operational system restores, but at least choose a few random files and restore them to check the capability to get your data back. Testing doesn't have to be done on each backup, but do it often and regularly enough so that you KNOW you can get your data back even if some of your media has problems or is lost. Professionally I have long liked IBMs TSM Storage Manager product with the Disaster Recovery option, but that is out of the price range for most. Doing good CPIO backups works well too. Even using the 'old fashion' dump level backups isn't a bad way to do backups. The first and most important rule in doing backups, is to do backups. Then do the regularly.
