Successful Backup Considerations

Backups can protect your investment in time and in data, but only if you are successful in backing up and keeping the information; therefore, part of a successful backup procedure is a test strategy to spot-check backups. The easiest way to spot-check your backups is to perform a restore with them, which you should attempt before it is actually needed.

If you automate the backup process, such as through the use of crontab scripts, make sure to perform extensive test runs in parallel with sure techniques before relying on automation.

The Difference Between Backup and Archive

You need to understand the difference between a backup and an archive. A good backup strategy involves both forms of data protection. Backups are file operations that save your data at regular intervals, either wholly or incrementally (see "Backup Strategies and Operations," later in this chapter). Archives are file operations that save your data for long periods of time. For example, the CD-ROM included with this book is an archive of the free portions of the latest Red Hat Linux distribution.
