Sorry for this noob question

I've read the documentation, but i can't figure if i'm right or not
I'm working on a new infrastructure, which is a classic veeam server, with an "automated HSM" storage.
I a have multiples backups job that backup my VMs : no problem. (

But, for archive purpose, i would like to have, every week : a copy of all my backup, put on a special repository (Which is then, manage by the HSM storage and archive to tapes), and with a 2 years retention
In my configuration : i (For the moment) cannot directly backup from Veeam to tape.
So my question : how do i manage to create a copy of my backups, every week, and that those copies remain accessible for the next 2 years.
For the moment, i've done a Backup Copy Job :
- which take backups that are 7 days olds
- Keep 96 points (4 weeks * 12 months * 2 years)
- Ask Veeam to delete file older than 750 days
Is this correct ?
