Making an incremental backup

An incremental backup is a backup of the transaction log file only. Typically, you should make several incremental backups between each full backup.

For more information about the difference between a full backup and an incremental backup, see Types of backup.

To make an incremental backup (overview)

1. Ensure that you have DBA authority on the database.

2. Make a backup of your transaction log only, not your database file.

For more information about how to carry out the backup operation, see the following:

• Making a backup, continuing to use the original transaction log.

• Making a backup, deleting the original transaction log.

• Making a backup, renaming the original transaction log.

Notes 

The backup copies of the database file and transaction log file have the same names as the online versions of these files. For example, if you make a backup of the sample database, the backup copies are called asademo.db and asademo.log. When you repeat the backup statement, choose a new backup directory to avoid overwriting the backup copies.

For more information about how to make a repeatable incremental backup command by renaming the backup copy of the transaction log, see Renaming the backup copy of the transaction log during backup.
