Comment RAID good if used properly (Score 1) 611

Yes, "RAID is not backup", in that you shouldn't simply RAID your primary drive and consider the backup problem solved, but backing up to a RAID array can be advantageous -- you do disk-to-disk backup (via any of a variety of methods), and monitor the health of the RAID array closely -- if any disk in the array goes south, replace it promptly and your backup stays consistent. And, if you keep a spare drive or two around, you can swap a drive out occasionally to take off-site (and let the array rebuild onto one of your spares).

Personally, I like the ReadyNAS Duo a lot more than the Drobo (hard to explain, I just trust their tech better, and the ReadyNAS is natively networked, rather than needing an afterthought add-on). Last I checked, Amazon will sell you an empty ReadyNAS Duo and a couple WD Green 1TB drives for ballpark $500. That said I haven't got a ReadyNAS yet (because money has so many uses these days); I'm using my second most favorite backup setup, a 500GB laptop drive in an external bus-powered FireWire enclosure. I'm using a MacAlly PHR-S250CC enclosure (which I'm very happy with), using a drive I already had, but for a complete setup, I'd probably go with one of Other World Computing's packages for about $150. This loses RAID (which I ultimately want very much to have, for reliability), and isn't networked (which would be good for backing up multiple machines, and ease of use), but the bus-powered drive is so damned easy to use that I actually do it every day (set the drive next to my laptop and plug one cable between them, Time Machine notices the drive and starts a backup, 5-10 minutes later it's done, and I unmount the drive, unplug the cable, and put it back on the shelf).

My primary machine is a Mac; I use Time Machine for daily backups, and use SuperDuper to clone my MBP's drive onto the same backup disk every few weeks (minus a number of large directories that I know Time Machine is getting anyway); this gives me a backup drive I can boot from (via SuperDuper), and a lot of incremental history stored in a very usable manner (via Time Machine). And a backup system that I actually use because it's painless.

Add a ReadyNAS, and I could have my laptop automatically backing (hourly) up any time it's on the home network.

As far as on-line backup goes, I haven't been convinced yet. It eats a lot of bandwidth, and it means that someone else (that I don't know personally) has a copy of all my data, with only their promise of encryption keeping them honest. Sure, there isn't much there for anyone else to get worked up about (a variety of legally purchased music and software, a bunch of old email and vacation photos), but if it's not out of my hands, then that's one less thing I have to worry about. I do love DropBox for moving non-confidential files around, but I wouldn't use it for backup.

Submission + - Choosing a Content Management System

Tokimasa writes: "I was recently asked to assist in the programming aspect of a website (PHP, Perl, SQL, and the like) while someone else works on the design of the site. However, I'm not sure if a full-blown CMS is required or if writing simple scripts would be of more use. How can I determine if a CMS is necessary, and if it is, how should I go about choosing a CMS to use?"

Submission + - First 'habitable' alternative to Earth found

ceros writes: European astronomers yesterday reported the discovery of a habitable planet located nearby in the constellation Libra. The so-called "super-Earth" is the smallest of the 229 planets found beyond our solar system. Moreover, it orbits within the "Goldilocks Zone" where temperatures are "just right" for water — and thus life — to exist.
