Specify advanced replica settings

At the Job Settings step of the wizard, click Advanced to specify additional settings for the replication job.

1. When VM data is transferred between two offhost backup proxies,

Veeam Backup & Replication compresses VM data to reduce load on the network.

Veeam Backup & Replication offers 4 compression levels that provide different compression ratios to meet the needs of your environment.

However, in this exercise, one backup proxy is used as a source and target proxy. For this reason, no compression will be applied.

2. Click the Notifications tab. Select the Send email notifications to the following recipients check box and specify the email address. When the job completes, you will receive an email notification with details on job performance. Note that you will be able to receive an email notification only if you specify global email settings (to specify email settings, select Options from the main menu).

Note Make sure that you specify your email address once: either in the To field in general notification settings, or in job notification settings. If you specify both, you will receive two identical notifications when the job is completed.

3. Click the Hyper-V tab.

5. Make sure that the Take crash consistent backup instead of suspending VM check box is selected. Veeam Backup & Replication will use the crash-consistent method instead of offline backup and will not bring the VM offline (to learn more, see the Insight into Veeam Backup section).

6. Make sure that the Use changed block tracking data check box is selected. In this case, Veeam Backup & Replication employs its proprietary changed block tracking technology.

Instead of scanning the VM image to know which data blocks have changed since the previous job run, Veeam Backup & Replication queries the CBT driver to get the list of changed blocks. Use of CBT increases the speed and efficiency of block-level incremental replication. For example, if only 5% of a VM changed since the last replication cycle, incremental replication will be performed 20 times faster.

7. Click the Advanced tab. Make sure the Exclude swap file blocks from processing check box is selected. Swap files are dynamic and change intensively between runs of a

replication job. With this option selected, Veeam Backup & Replication will identify data blocks of the Windows pagefile in the guest OS and exclude them from processing, which will result in increased performance and a smaller size of increments.

Step 8. Specify additional guest OS processing options

This step should only be performed if you replicate Windows-based VMs with VSS-aware applications. For such VMs, you can enable application-aware image processing that will ensure proper restore of these applications.

To replicate VMs with VSS-aware applications such as Active Directory, Microsoft SQL, Microsoft Exchange and SharePoint without shutting them down, Veeam Backup & Replication uses application-aware image processing (based on Microsoft VSS). Jobs with application-aware image processing produce transactionally consistent replicas, that, unlike crash consistent replicas,

2. Specify guest OS credentials (username and password) with Local Administrator privileges on all VMs included in the job. OS credentials are required to install, start and remove a small runtime agent that coordinates VSS activities inside the VM.

3. By default, the specified guest OS credentials are used for all VMs processed by the replication job. If you replicate several VMs that use different guest OS credentials, click Advanced. Select a VM in the list and click Set User. Then enter guest OS credentials with Local Administrator privileges for this specific VM. Repeat the procedure for all VMs in the job.

4. To specify advanced options for VSS processing, select a VM in the list and click Edit.

5. Select the Ignore application processing failures option to continue the replication job

6. Make sure that the Truncate logs on successful backup only option is selected to correctly handle transaction logs after the replication job is complete. In this case, if the replication job finishes successfully, Veeam Backup & Replication will truncate transaction logs so that they do not overflow storage space. If you use a third-party backup tool that maintains the consistency of transaction logs, select the Do not truncate logs option to prevent possible conflicts.

Step 9. Specify job scheduling settings

A replication job can be scheduled or run manually. To schedule a replication job:

1. At the Schedule step of the wizard, select the Run this job automatically check box. If you do not select this check box, the job will be saved and you will have to run it manually.

2. Select the schedule type: daily, monthly, periodically or continuously. You can also chain the jobs so that they run one after another.

3. Select the Retry failed VM processing check box. During the retry cycle, only VMs that failed during the main replication cycle will be processed.

4. Select the Terminate job if it exceeds allowed backup window check box and click Window. Define the backup window for your environment. In case the created job overlaps the specified window, it will be automatically terminated not to produce additional

overhead on your virtual environment.

5. Click Create.
