VEEAM - Archiving Backups

[CHiLL]

We use VEEAM to backup our servers. At the moment, they are configured:

 

Backup Jobs perform reverse incremental backups each night to our high capacity SAN, with the first server starting at 9pm each week night and the rest of the servers starting in a chain event from when that one completes.

Backup Copy Jobs for each server runs each night to backup the backups to one of our NAS devices in another building. (NAS device limited on space)

Backup Copy Jobs for each server runs each night to backup the backups to another one of our NAS devices in a another different building. (NAS device limited on space)

 

The reason I had that configured all within VEEAM is that it keeps it all in one place, however I'm not sure how to configure what I'm after.

 

Ideally I'd like the Backup Jobs to create monthly, quarterly and yearly full archives to the high capacity SAN...however that feature only appears to be available on Backup Copy Jobs.

The reason that the Backup Copy Jobs are not configured in that way is because the target NAS devices are not large enough to store the backups and archived data too.

 

How can I configure VEEAM so that it will store the archived data to the large SAN?
