This technical note is the second of two parts. Part 1 was entitled General Principles of Database Backup and Recovery.

The trend that we are seeing in ACI Technical Support is that thousands of customers are using 4D Server for mission-critical data storage. Daily, we are talking with customers who have 4D Server installations with as many as 100 users connected, and with data files as large as five gigabytes. The customers view these applications as “mission-critical,” meaning that the organization cannot function properly if the system is down. Often, these databases are running 24/7: twenty-four hours a day, seven days a week.

You can depend on 4D Server to give you mission-critical, 24/7 stability, if you apply some common sense to your Database Administration duties and if you follow a few simple rules of backup and recovery. Many customers have been able to maintain 4D Server installations that run for months—even years—with little or no downtime. The purpose of this two-part technical note is to provide you with the information that you need in order to set up a 4D Server installation that gives you that kind of stability and reliability.

In this part, Automatic Backup and Mirroring with 4D Backup. we will cover:
• The concept of 4D Backup
• Tricks and tips for using 4D Backup
• Tricks and tips for mirroring with 4D Backup
