Tips On Building A Backup System at Home
Develop a low-cost, terabyte-sized backup equipment utilizing Linux and back up everything including all the digital audio files, digital images and digital movie recordings.
A file system backup is now an very affordable choice for Linux system end users. Options with regard to constructing and setting up an reasonably priced, expandable, Linux-based backup device is not possible.
Server Architecture
High-capacity hard disk drives are finally largely readily available at prices that are incredibly low-priced when compared to those of only a very few years ago. In addition, with so many Linux users now recording CDs to disk, almost certainly saving images from their digital cameras and producing video using digital video cameras and DVRs, the need for back up and archiving large amounts of data is becoming critical. The loss of images and videos of your children or your audio tunes library—because of a disk freeze would be a devastation. Thankfully, a high-capacity, Linux-based backup server can be developed very easily and low-priced using inexpensive disk drives and free software.
Essentially any home PC will meet the fundamental requirements for a backup server. If you have extended back-up windows or fairly small amounts of data, a slower computer system is usually not an barrier. Try to make certain the computer network is fast enough to move data inside of your backup window. With regard to older equipment, the bottleneck for backups can be the disk data transfer bandwidth (30-150Mbps depending on disk technology).
Lots of consumer-level pcs do not currently have cooling capacity for more than two internal hard disks. Most motherboards support a maximum of four onboard hard disk drives (often four ATA/IDE devices, but the two ATA/IDE and two SATA combination is becoming common). External USB high-capacity devices are also on the market. If your pc is outdated and has USB1, buy an inexpensive USB2 PCI expansion card, which is 10 times faster.
SCSI has less limits, but it is highly-priced and has tended to lock buyers in to "flavor-of-the-month" SCSI technologies. One particular solution for disk expansion and upgrade is the Host Bus Adaptor (HBA), such as those made by Promise Technology. An HBA is a disk controller on a PCI expansion card. HBAs generally require no additional software, have their own BIOS and are not constrained by PC BIOS limits on disk size. HBAs enable you to put sizeable disks (more than 120GB) into systems with legacy BIOSes, upgrade from ATA-33 to ATA-150 or mix ATA and SATA disks.
You actually may want to look at getting a dedicated fileserver. A bare-bones server capable of holding 6 disks (fully preassembled, no disks or OS) can cost much less than $1,500 . Along with this initial investment, you can improve disk space as needed for less than $0.80 per GB or expand by plugging in USB disks. When you have made the decision how many hard disk drives you will need, consider their space, cooling and noise demands.
Even in the event that you choose to build a server from scratch and populate it with high-capacity hard drives, you can assume expenses for your terabyte-plus backup server still to be small in terms of its per-gigabyte cost. This is for the reason that storage expenditures have dropped so drastically. Costs for a brand new machine equipped with more than two terabytes of storage can be developed for a cost of less than $1.50 per gigabyte. That will back up a lot of home movies, digital pictures and music files!
