How to find the right backup for your business

Safeguard data the easy way

Sure, storage options vary in speed, price, security, and convenience, but nothing is more important than their ability to safeguard vital data.

Like real estate, storage has some key attributes that are easy to sum up: backup, backup and backup. The potential costs of media failure far exceed the financial outlay for a RAID configuration or for offline backup. Here are four strategies for achieving adequate storage capacity and the redundancy needed to keep your data safe.

Directly attached hard drives

Direct-attached drives — the most common type of add-on storage — come in a single- or multiple-drive enclosure that typically hooks up to your PC via a USB 2.0, FireWire, or eSATA connection (eSATA is the latest and fastest of these types, but you’re likely to need an adaptor to connect it to your computer).

If you just want the storage drive to back up the internal disk inside the PC it's attached to, a single drive works fine. Click here for reviews of directly attached hard drives.

If you’re expanding core storage, rather than just backing it up (on a server, for example), consider investing in a multidrive RAID system with built-in redundancy. This will protect you from drive meltdowns, though you should also have an off-site or internet backup plan to guard against disasters like fires and floods.

Look for RAID 1 or RAID 5 support; either arrangement will let you replace a failed drive without losing data.

Network-attached storage

For most small businesses, a NAS drive is the best option for central file storage and backup. NAS drives also provide web and FTP access to your files, and act as print servers. After initial setup, NAS drives require little administration (a boon for small businesses without IT staff), and they can be secured with encryption and passwords.

For top performance, choose models with gigabit ethernet connections, and make sure you have gigabit routers and switches in your office. Backups can be bandwidth intensive.

Two excellent NAS products designed for small businesses are the Iomega StorCenter Pro 150d and the Netgear ReadyNAS NV+.

Both of these devices are hot-swappable, and they offer RAID 1 and 5 support, gigabit ethernet, web-based administration, and software for backing up local drives.

Portable storage

Portable USB hard disks and flash drives are great for travel, for moving large files around the office, and for laptop backup. They can be a serious security risk if lost or stolen, however, so it’s imperative to use encryption software on any drive that might leave the office.

The Lexar JumpDrive Lightning and the SanDisk Cruzer series are popular flash drives with strong encryption software. Add-on software like Migo’s Digital Vault will secure any USB hard disk or flash drive.

Examples of portable drives that you can power through your USB port include Maxtor’s OneTouch III Mini, Toshiba’s Portable External Drive, and Western Digital’s Passport. Prices are typically £50 to £100 for 100GB to 250GB drives. Note, however, that the disks in these compact cases tend to be 5400rpm laptop drives, which are considerably slower than the 7200rpm drives used in desktop PCs.
