Creating and Restoring Database Backups

In the same example, the Interplay Engine does not check the number of backups again until it
performs a Complete backup on Sunday the 15th. On that day, it deletes the 7 oldest backups,
leaving 8. The following illustration shows the 7 oldest backups deleted.

If you check the _Backup folder before the Interplay Engine finishes a Complete backup, it is
possible for the _Backup folder to contain more than the specified number of backups to keep.
Scheduling Automatic Database Backups
The Schedule Backups view in the Interplay Administrator lets you schedule the type and
frequency of your automatic backups. You can schedule two kinds of backups: Complete and
Fast. You can schedule one of two different Fast backups: Incremental or Differential. For a
description of the different types of backups, see
“Types of Interplay Administrator Backups” on
page 30
.
The Interplay Engine performs an automatic backup without locking or shutting down the server,
and users can continue to work with the database. During a backup operation, all actions on the
engine are cached to ensure a fully consistent backup. As a result, the performance of the
Interplay Engine is slower. You should not schedule large-scale deletions during a backup
operation.
When a backup is in progress, status messages are displayed at the top of the view.
