Small Business Server Backup - How to Backup a Small Business Server - Small Business Server Backup Types, The Complete Backup, The Incremental Backup

Backing up a small business server is one of the most important IT tasks involved in running any business that requires a server to operate. The server is responsible for routing all data to the appropriate databases, files, and hard drives, most of which are a part of the server. It is also responsible for hosting email and other applications necessary for the business. The loss of any information stored on the server could be a disaster just as big as any fire, earthquake, or other force of nature.

Because a small business server backup is so essential, it is necessary to take a look at all the options available. Different types and methods of backups suit different types of businesses and management styles, so knowing all the options is the first step in making the right decision.

Small Business Server Backup Types

Backing up a server consists of making a second copy of the data and files stored on the server in case a hardware failure causes the loss of the original. Three basic types of backing up data exist. Some small businesses will use only one of the three, but many find it appropriate to use different methods in different situations.

The Complete Backup

A full, or complete, backup is the most thorough and time consuming of the three basic types of backups. A complete backup copies every file on the server to a second location. This type of backup is usually the first type done when implementing a new backup system because it is necessary to copy all files, whether they have changed in the past day, week, year, or not at all. Some companies with appropriate downtime, such as 8 hours overnight, use daily complete backups because even though they take the longest, they are the simplest to implement. Other companies use complete backups only on a monthly, annual, or situational basis. Complete backups can be accomplished by using third-party software, manually copying the files, or by using automated scripts within the operating system.

The Incremental Backup

An incremental backup of a small business server consists of updating a complete backup by appending it with all the files that have changed since the last complete backup. The incremental backup is much less time consuming, but it does require a small business to perform a complete backup on a regular basis. Otherwise, each changed file gets backed up every time the incremental backup is performed, meaning each backup performed after the complete backup gets longer each time. Because each incremental backup contains the data of the previous incremental backup, it is usually done on the exact same space. This makes incremental backups useful when there is limited space to store the backup. Since the advent of the third type of backup, the differential backup, incremental backups are becoming less common.

The Differential Backup

A differential small business server backup consists of backing up only the files that have changed since the last backup of any type. This is the most popular type of server backup because it is usually the type that takes the least amount of time and the least amount of resources. With a differential backup, the changed data is appended to previously written data, so snapshots of the server state are created that can go back since the last complete backup. This means that a server state can be restored to any point in time in which a backup was made, not only to the last backup. This allows files to be pulled out of the server history that have been accidentally deleted or erroneously modified. Although it is not a good habit to get into, many small businesses use differential backups to correct everyday mistakes. The drawback of differential backups is that they require the most space.

Small Business Server Backup Methods

The methods used to backup small business servers are limited, so making a choice usually boils down to choosing a specific type of software that handles the backup.

Some businesses use in-house developers to write a piece of code into the operating system to perform backups as needed. Some operating systems already have built-in backup systems that can be easily setup and controlled by a wizard interface. Some companies just have a person copy and paste all the files from one hard drive to another.

The most common method of backing up a server is to use third-party software. Third-party software offers a great deal of choice in how and when backups are completed.

Another, newer, type of backup is based on the concept of cloud computing. Backups are not done by in-house IT personnel running third-party software, instead they are done by a company that backups the data using their own proprietary software on their own servers, backing up the data to hard drives through the internet. Storage space is leased by gigabytes, and fees are determined by the frequency of backup and space needed.
