Business technology s demands today are, and will always be,ever-increasing. This is even more apparent in the storage arena.Larger file formats, increased data usage, and the number ofcompanies relying on computers to keep their business going allfactor in on the need to rely on bigger, faster, and better ways tostore data. IT vendors help keep up with the demand by releasinglarger disk drives designed for speed, capacity, and reliability.But even when one disk drive can t handle all the demand, we findways to creatively design disk systems that can hold largercapacities with the extra security of redundant modes of operation.In business computing, of course, you can t talk about storagewithout having adequate backup. Traditionally, tape has always been the way to store archived datafor short and long term periods. As a longer-term backup solution,tape works great, as its small footprint doesn t take up too muchspace, capacities have significantly increased over the years, andmany manufacturers still support it.
As a short-term backupsolution, though, tape is just not that convenient of a media.Loading a tape cartridge for a restore and having to finding therequested data takes time that, in the computing world, can feellike hours. Managing these small, delicate backup cartridges canalso be overwhelming to the system admin, as they have to rotateand index numerous tape cartridges to keep up with the dailybackups, while at the same time keeping the strips of magnetizedfilm safe from the elements. Ideally, there should be a better wayto be less reliant on tape when it comes to short-term filestorage. This concept that I m leading to is disk-to-disk backup.
As I mentioned, disk drives are constantly improving in performanceand capacity. Along with each new model that gets released,previous models drop in price to much more affordable levels.Advantageous in not just cost per gigabyte, disk drives are easilyaccessible, faster than tape, and can store plenty of hot data thatwould take more effort to retrieve off of a tape cartridge. To topit all off, disk drives are much more "storable" than tape, as thedata is kept on metallic platters sitting in sealed, hard casings. About two years ago, I wrote a review about a hard drive-basedbackup system that uses several independent disk drives connectedto a computer via an eSATA connection. Highly Reliable Systems, theReno, Nevada-based company that brought us the seven-bay High-Relybackup system, now has something that could be considered a step upwhen backing up data to disk.
The High-Rely RAIDFrame Backup System is an eSATA-based JBODsolution that gives you five separate RAID storage devices in onechassis. Designed for techies that don t mind being a littlehands-on, the RAIDFrame can provide backup functionality over a 3Gb/s eSATA connection from a single or, if configured, multiplehosts. Not only do you get fault tolerance in a small package, butyou can also get up to well over 4TB of disk space if you use largeenough drives.
