Real Time Backup


Manage Data Threats

applications powered by Pervasive PSQL databases are mission critical. The data in these applications are high-value, time-sensitive corporate assets. Unfortunately, there are numerous threats to your data, including:

  • Hardware failures. The most common are computer or disk crashes. Causes range from random failures to accidents like spilling water onto a server.
  • Site disasters. These range from high-profile disasters like fire or earthquake to more mundane occurrences like power surges, water pipe breaks or virus attacks.
  • User and application errors. These encompass everything from accidents like incorrectly upgrading the operating system to malicious acts like deleting files or introducing viruses.

The Pervasive DataExchange Real-Time Backup Edition addresses each of these threats.

Given the mission critical nature of your data, the business cost of data loss or data interruption is high. When planning a disaster recovery strategy, the two key questions to ask are:

  • How much data can I lose? This is a data freshness question. Rapidly moving data from your mission-critical system to a backup minimizes data loss.
  • How long can I be down? This is a data recovery question. Having a functional database server on standby minimizes downtime. Many companies use tape backup and/or server clustering as their backup strategy. Tape backup is a low cost and reliable, but data on tape is only as fresh as the last backup, since it is impractical to backup a large in-service database. Server clustering usually provides adequate protection against localized hardware failures, but leaves data exposed to site disasters since the only safe copy of data is the tape.

The DataExchange Real-Time Backup engines are restricted to one-way replication, and the replication network is restricted to two databases.
