Maintaining the database

Deleting old backups
When running a compact or a backup on the NOAH database, a backup file of the database is automatically created for security reasons. We advise users to, once in a while, delete old backup files.

Restoring
If you experience problems with your database, and can no longer use it, you may wish to use a backed up copy of the database. This assumes that you have been backing up your database.

Replacing
If you wish to replace your database because of errors, but do not have a backup file, you can replace your current database with a new, EMPTY database.

Repairing
Use the repair utility when NOAH cannot start due to a database error. You can also attempt to repair a database if you have unpredictable results when running NOAH.

Compacting

As you change data in a database, the database file can become fragmented and use more disk space than is necessary. Compacting reduces the database size by defragmenting the data. The compacted database is usually smaller and often runs faster.

Backing up

The backup utility makes a copy of your database and stores it in a location of your choosing. If your database is already backed up as part of a regular backup routine that backs up your entire computer, it is not necessary to use the NOAH Database Tool’s backup utility.
