Health check - if scheduled, backup file integrity is verified beforeĭata transfer (synchronization) phase - during this phase, the backup copy job checks for a new restore point in the source, creates a file for a new restore point at the target and starts copying the state of the latest restore point of each processed VM to the target repository. Pre-job activity - if enabled, the pre-job scripts are executed at the The backup copy job has the following phases: Think of it almost like about setting an SLA. The reason for this design is that you may run local backups more often (for example, hourly), but you may only want to copy data offsite only daily or weekly, thus you can set the backup copy "interval" independently of the schedule of the backup jobs it is monitoring. Since the copy job can contain multiple source backup jobs, and most source backup jobs neither start nor complete at the same time, the synchronization interval is helpful in defining a SLA for when it should look for restore points across the included source jobs. The synchronization interval is implemented to provide a policy driven approach to offsite copies. However, once a single point is copied, another point for that VM will not be copied until the next interval starts. When the restore point is found, the copy job will copy it.

If you set an interval of 1 day, that equals to instruct the backup copy job that once a day, starting at the selected time, it should begin looking for new restore points. The concept of the "interval" is used to define two parameters: how often it should be looking for new points, and for daily intervals at what time it should start looking for points. This is especially helpful, when transferring multiple times per day (e.g.

On the Schedule tab, it is possible to schedule the when data transfers are allowed. This process includes several stages.Ī copy job restarts at the defined Copy every interval setting (default is 12:00 AM daily) and looks for new restore points of the selected VMs in the specified sources. Backup Copy Job Schedulingīy design, a backup copy job is a process that runs continuously. Important Note: only Cloud Connect jobs or Backup Copy Jobs with WAN acceleration enabled are serial, in all other scenarios backup copy job has parallel processing. Limitations of backup copy jobs are described in Veeam Backup & Replication User Guide at. The backup copy process will be paused and resume during the next synchronization interval. This might be caused by precedence of the backup task over the backup copy task. If a backup copy job cannot process all requested VMs during an incremental execution interval, the job will still create a backup file on the target backup repository, but some VMs will be left inconsistent or unprotected. If you plan to use Grandfather-Father-Son (GFS) retention, refer to the “ GFS Retention Policy” section for details.īackup copy jobs file chains layout will depend on the repository option: "Per VM backup files" will generate one file chain per each VM, otherwise a chain will be generated per each job.

Once created, a backup copy job will immediately start processing the latest existing restore point for all VMs included in the job, as long as it has been created less than one synchronization interval before the start of the backup copy job.īy default, Veeam Backup & Replication keeps 7 restore points on the target backup repository in case of simple retention policy (see the “ Simple Retention Policy” section of the User Guide for details). The folder has the same name as the backup copy job. You can store VMs from multiple backup jobs in the same backup copy job, or you can select a subset of VMs from a bigger backup job as source if you do not want to backup all VMs to the backup copy job destination.Įvery backup copy job creates its own folder on the target backup repository and stores its data in this location. The second chain is independent from the first chain and adds therefore an additional level of protection. Backup copy jobs read specific VM restore points from backup files and store them as a new backup file chain on the destination. Instead of just copying backup files to a second destination, Veeam uses a more intelligent and secure way of bringing restore points to a second backup target.
