Backup Copy
To enhance protection of your data against disasters, you can extend your backup jobs with backup copy capabilities. With backup copy, you can transfer backups created by backup jobs from a source backup repository to target backup repository for long-term storage.
Both source and target backup repositories for backup copy must be extended with object storage and located on the same backup proxy server and have the same retention type. For more information on how to extend a backup repository with object storage, see Specify Object Storage.
As well as backup, backup copy is a job-driven process. You can create a backup copy job right after configuring a backup job or at any time later. Keep in mind that an extended backup repository that you configure as a target for your backup job becomes a source backup repository for backup copies. A target backup repository to store backup copies must be specified when you configure a backup copy job. For more information, see Creating Backup Copy Job.
The following table lists cloud and on-premises services that Veeam Backup for Microsoft 365 supports as a source and target for backup copy jobs.

Storage format of backup copies differs from storage format of backups: maximum size of blob files increases from 5 MB for backups to 256 MB for backup copies. Repacking of backed-up data is performed by either Veeam Backup for Microsoft 365 backup proxy or an auxiliary archiver appliance that Veeam Backup for Microsoft 365 can create in Microsoft Azure or Amazon EC2. Processing larger blobs helps you reduce costs incurred by your cloud storage provider for retrieving backed-up data from backup copies.
Veeam Backup for Microsoft 365 allows you to protect data in backup copies from loss as a result of attacks, malware activity or other injurious actions that may be performed by 3rd party applications. For more information about protecting data in backup copies, see Immutability.
