If your computer runs VSS-aware applications, you can enable application-aware processing to create a transactionally consistent backup. The transactionally consistent backup guarantees proper recovery of applications without data loss.
To enable application-aware processing:
- At the Guest Processing step of the wizard, make sure that the Enable application-aware processing check box is selected.
- Click Applications.
- In the Processing Settings window, on the General tab, specify if Veeam Agent for Microsoft Windows must process transaction logs [For Microsoft Exchange, Microsoft SQL and Oracle] or copy-only backups must be created.
- Select Process transaction logs with this job if you want Veeam Agent for Microsoft Windows to process transaction logs.
[For Microsoft Exchange] With this option selected, Veeam Agent for Microsoft Windows will wait for backup to complete successfully and then trigger truncation of transaction logs. If the backup job fails, the logs will remain untouched until the next backup job session.
[For Microsoft SQL Server and Oracle] You will have to specify settings for transaction log handling on the SQL and Oracle tabs of the Processing Settings window. For more information, see Transaction Log Settings: Microsoft SQL and Transaction Log Settings: Oracle.
- Select Perform copy only if you use another tool to maintain consistency of the database state. Veeam Agent for Microsoft Windows will create a copy-only backup. The copy only backup preserves the chain of full/differential backup files and transaction logs. For more information, see http://msdn.microsoft.com/en-us/library/ms191495.aspx.
