Schedule backups

You recovery strategy should include a schedule of backups. Tailor your backup plan to the requirements of your system. The more often the data changes and the more important it is, the more frequently you need to back it up.

Your backup plan should also specify the backup level.

The following table shows a sample backup plan for a small or medium-sized system.
Table 1. Sample backup plan
