If you want to create a transactionally consistent backup or replication ensuring successful recovery of VM applications without any data loss, take the following steps:
- Select the Enable application-aware image processing check box.
- Click the Applications button.
- To define custom settings for a VM in the list, select it and click Edit. Consider the following:
- To customize settings of a VM added to the job as part of a container, the VM should be included in the list as a standalone instance. For that, click Add VM and select a VM whose settings you want to customize. Next, select the VM in the list and click Edit to define the necessary custom settings.
- To discard custom settings of a VM, select the VM in the list and click Remove.
- Configure the necessary settings for the selected application server, as described in the paragraphs that follow.
In This Section
In this section, select the option that corresponds to a transactionally-consistent backup creation scenario of your choice:
- Select Require successful application processing (default option) if you want Veeam Backup & Replication to stop backup of the VM if any error occurs.
- Select Ignore application processing failures if you want to continue backing up the VM even if errors occur. This option is recommended to guarantee completion of the job. The created backup image will not be transactionally consistent, but rather crash-consistent.
- Select Disable application processing if you do not want to enable quiescencing for the VM at all. In this case, log processing settings (the section below) will become unavailable.
Transaction Logs Processing Section
In this section, specify whether this job should process transaction logs upon a successful backup:
- Select Process transaction logs with this job (recommended) if you want Veeam Backup & Replication to handle transaction logs. With this option enabled (default setting), Veeam will support log pruning for Microsoft Exchange and Microsoft SQL servers, as well as for Oracle databases archived logs:
- Truncation of transaction logs for Microsoft Exchange server will be performed after the job completes successfully: the Veeam runtime process will wait for VM backup to complete and then trigger truncation of transaction logs. If truncation of transaction logs is not possible for some reason, the logs will remain untouched in the VM guest OS until the next start of the Veeam runtime process.
- Settings for SQL server transaction log handling can be configured separately on the SQL tab - it becomes available to you with this option selected.
- Similarly, you can configure settings for Oracle database archived logs processing on the Oracle tab.
- Select Perform copy-only (lets another application use logs) if you want to use native application means or a third-party tool to process transaction logs. Veeam Backup & Replication will create a copy-only backup for the selected VM. The copy-only backup preserves a chain of full/differential backup files and transaction logs, so Veeam Backup & Replication will not trigger transaction log truncation. This option is recommended if you are using another backup tool to perform VM guest-level backup, and this tool maintains consistency of the database state. To learn more, see Veeam Backup & Replication User Guide.
With this option selected, the SQL and Oracle tabs will not be available.
To configure settings on the SQL tab, follow the instructions provided in the Backup and Restore of Microsoft SQL Server Databases.
To configure settings on the Oracle tab, follow the instructions provided in the Backup and Restore of Oracle Databases.
On the File Exclusions tab, specify whether to exclude or include specific files in the backup. Exclusions can help to decrease backup file size. However, remember that selective processing takes additional time that depends on the number of excluded files; also, it requires obtaining per-file metadata (stored in backups). Thus, it is recommended to use this option for excluding large files. By default, exclusions are disabled.
- Exclude the following files and folders – with this option selected, you can specify what files and folders must be excluded from the backup.
- Include only the following files and folders – with this option selected, you can specify exactly what files and folders should be only included in the backup.
Click Add and specify what files and folders you want to include or exclude.
To form the list of exclusions or inclusions, you can use full paths to files and folders, environmental variables and file masks with the asterisk (*) and question mark (?) characters. For more information, refer to the corresponding section of the Veeam Backup & Replication User Guide.
