Disaster recovery for small business--sunbelt.Large businesses aren't the only organisations that need disaster recovery plans; small businesses must also prepare for any number of catastrophes. For small companies, large-scale disaster recovery tools may not be fiscally feasible, but they may also not be very necessary. While small business do indeed need DR systems in place, they generally don't need to protect systems at the same level as large organisations. This isn't because the data isn't as important--there probably just isn't as much data as you would find in large companies. Real-tme replication In database management, the ability to keep distributed databases synchronized by routinely copying the entire database or subsets of the database to other servers in the network. There are various replication methods. and other higher-end technology is definitely an option, but it's usually not mandatory. Tape is always a good starting place for small firms. You can purchase many tape systems for a reasonable price, and they can back up your entire infrastructure at once in many cases. While some small organisations may need to find a slightly larger tape system, the basic systems will workjust fine in the majority of cases. This typically entails a daily copy of all changed data and a weekly full copy of all data. After making the tapes, be sure to remove the copies from the office, leaving only the most recent tapes in the facility, If there's a flood, fire, or some other physical mishap (language) MISHAP - An early system on the IBM 1130. [Listed in CACM 2(5):16, May 1959]. that destroys the on-site tapes, you'll still have backup copies A disk, tape or other machine readable copy of a data or program file. Making backup copies is a discipline most computer users learn the hard way-- after months of work is lost. See backup and LAN free backup. . Small organisations that have more than one office can find many host-based replication systems that don't require higher-end disk arrays to transmit data. These tools use the operating system operating system (OS) Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. on the individual servers to send copies of data between locations. While this solution requires a server at both sites, it typically doesn't require much else. Of course, you don't want to eliminate tape from your environment, so use this solution in addition to using a tape backup Using magnetic tape for storing duplicate copies of hard disk files. Users can add an internal or external tape drive to their desktop computers for backup purposes, and files are typically copied to the tapes using a backup utility that updates on a periodic schedule. system. Host-based replication systems cost more than tape backup alone. However, if you have data that you must protect in real-time 1. real-time - Describes an application which requires a program to respond to stimuli within some small upper limit of response time (typically milli- or microseconds). Process control at a chemical plant is the classic example. or near-real-time, this is a cost-effective cost-effective, n the minimal expenditure of dollars, time, and other elements necessary to achieve the health care result deemed necessary and appropriate. method of gaining the protection your Organisation needs. |
