Online backups happen frequently, and without stopping the server. For online backups,
you need to back up only the database.
About this task
Because the database data is more important for deployments to run than the file system
data, online backups typically include only the database and not the server file system and
application data directory. Use the backup options for your database system.
Note: To make the online
backups easier to restore, configure your database to create full regular restore points and to
enable transaction logging. For example, the database might make full backups once a month and log
transactions all the time. That way, you can restore the database at any time.
