As we prepare to launch our new line of high capacity network storage systems, we’re giving a lot of thought to data backup. The very idea of a 7TB storage system filled with data is enough to make a cautious person break out in a sweat.
The truth is, most computer users neglect to backup their data, and eventually they will lose some or all of it. It’s inevitable…highly complex electro mechanical devices storing trillions of bits of data that can be rendered unreadable by a microscopic failure.
The TeraSpool systems can be configured using RAID 1 and RAID 5, each of which gives some measure of protection against the failure of one drive in the system. However, they can do nothing in the case of the destruction or theft of the entire machine. Further, if two drives fail, all the data is lost. The only real solution is a separate, comprehensive backup of the data.
Options For Complete Backup
How you choose to back up you data depends in part on how often the data changes, and of course on how much data there is. Here are some of the common approaches to data backup:
- Removable hard drives (typically connected via FireWire) are connected occasionally to make a backup copy of the data.
- A separate server (preferably in a different location) with capacity equal to all the data to be protected is synchronized with the ‘main’ data using an automated tool like Rsync.
- Key data is written to DVD-R discs from time to time. This is only practical for relatively small amounts of data, and files no larger than 4.7GB.
- Backup software, such as Retrospect, is set up on a server and writes its backup files to either local hard disks or another network storage system.
The bottom line is that if you don’t backup your data, eventually you’ll lose it. And backing it up means you need to have twice as much disk capacity available (at least) as you have data.
When you purchase a TeraSpool storage system, we can help you decide on an appropriate backup strategy and recommend hardware and software to implement it.
