To back up is to create a copy or image of a database, Transaction Log, Database Differential, a list of changes that have been made since a previous backup, or a collection of files or FileGroups on another device (typically a media drive). Use Arcserve Backup and the Agent for Microsoft SQL Server to perform backups using the SQL Server Backup statement.
Backing up a database creates a copy of its tables, data, system objects, and user-defined objects. In the event of media failure, if you have been making regular backups of your databases and their Transaction Logs, you can recover your databases.
Important! Transaction Logs are not backed up or truncated during full or differential database backups. To back up and truncate Transaction Logs, perform a separate Transaction Log backup. When you perform the Transaction Log backup, select the Remove inactive entries from Transaction Log option to truncate the log files. For more information about Transaction Log backups see Transaction Log Backups.
When a Microsoft SQL Server database backup is started in Arcserve Backup, the Agent for Microsoft SQL Server initiates an online backup of the database. This backup takes place while the database is active. The backup captures the state of the data at the moment the statement is executed. No partial transactions are captured. Any data changes made after the backup begins are not captured in the backed up copy of the database.
