To follow the 3-2-1 backup best practice, you can configure a backup copy job and target it at the cloud repository. Backup copy jobs allow you to create several instances of the same backup file in different locations, onsite or offsite. For example, you can configure a backup job to create a VM backup on the local backup repository, and use the backup copy job to copy the created VM backup from the local backup repository to the cloud repository. Copied backup files have the same format as those created by backup jobs, and you can use any data recovery option for them.
During the backup copying process, Veeam Backup & Replication does not simply copy a backup file from one backup repository to another. Instead, Veeam Backup & Replication retrieves data blocks necessary to create a restore point as of the latest point in time and copies this data to the cloud repository. The backup chain produced on the target backup repository is forever-incremental: the first file in the chain is a full backup while all subsequent restore points are incremental.
The backup copy process is job-driven. When you create a backup copy job, you define what backup file you want to copy, the target repository for storing the copy, retention policy and other settings for the copying process. The backup copy job supports the GFS retention scheme, allowing you to design a long-term archiving plan.
The backup copy job runs continuously, in cycles. By default, a new backup copy cycle begins every day; however, you can specify any time interval needed. At the beginning of every backup copy interval, Veeam Backup & Replication checks the source backup repository: if a new restore point has been added to the primary backup chain, Veeam Backup & Replication automatically copies it to the target backup repository. After that, the backup copy job is put on hold until a new backup copy interval begins and a new point appears on the source backup repository.
To create a backup copy job:
- On the Home tab, click Backup Copy and select VMware or Hyper-V.
- At the Job step of the wizard, specify a name and description for the backup copy job.
- In the Copy every field, specify the time interval according to which the synchronization process must start. Veeam Backup & Replication will check if new restore points are available in the source backup repository. If a new restore point is found, it will be copied to the target backup repository within the synchronization interval.
- At the Virtual Machines step of the wizard, click Add and select Jobs whose restore points you want to copy from the local backup repository to the cloud repository. To quickly find the necessary object, use the search field at the bottom of the Add Objects window.
- If you want to exclude VMs from the VM container from the job, click Exclusions and specify what objects you want to exclude.
- At the Target step of the wizard, from the Backup repository list, select the cloud repository to which you want to copy the VM backup.
- To use the GFS (Grandfather-Father-Son) retention scheme, select the Keep the following restore points as full backups for archival purposes check box. In the fields below, define the number of daily, weekly, monthly, quarterly and yearly full intervals for which backups must be retained.
- At the Data Transfer step of the wizard, specify a data transfer path for the backup copy job.
- If you have not chosen to use WAN accelerators, select Direct.
- If you have chosen to use WAN accelerators, select Through built-in WAN accelerators. In the Source WAN accelerator field, select the WAN accelerator that you have configured on your side.
- At the Schedule step of the wizard, define the time span in which the backup copy job must not transport data over the network. You can use this option, for example, to disable the backup copy job during production hours not to produce workload on the production environment.
- At the Summary step of the wizard, select the Run the job when I click Finish check box if you want to start the created job right after you complete working with the wizard.
- Click Finish.
