The Backup Copy functionality allows you to create several instances of the same backup in different locations, whether onsite or offsite. Backup copies have the same format as those created by backup jobs and you can recover your data from them when you need it.
Backup copy is a job-driven process. Veeam Backup & Replication fully automates the backup copy process and lets you specify retention settings to maintain the desired number of restore points, as well as full backups for archival purposes.
When enabled, the backup copy job for Veeam Plug-in backups runs continuously.
For details on how it works, see the Backup Copy section of the Veeam Backup & Replication User Guide.
