What is backup archive and how does it work?

Backup archive feature can be used to move your backup data from the backup storage to a more cost-effective storage for long term preservation. 

Your data which is no longer been used or is inactive but still has business values can be archived, this can make sure the data is still accessible when needed.

Vinchin Backup & Recovery supports archiving your backup data to onsite storages and cloud object storages. While cloud object storage is used for archiving, it is also an option of cloud DR (Disaster Recovery).

Although backup archive and backup copy can be used for disaster recovery, but they work in different ways. Backup copy will make an exactly the same copy of your backup data to another storage, while  a full restore point will be saved in the archive storage after each backup archive job session.

When the archive job session runs upon a full backup, all data blocks of the full backup will be directly transferred to the archive storage. When it runs upon an incremental/differential backup, required data blocks from all dependent restore points will be transferred to the archive storage and saved as a new full restore point.

So backup archive job should not be scheduled too frequently, otherwise there will be too much duplicated data written into the archive storage.
