Moving old backups to Bluray mdisc or dvd for archiving

Hi guys, I hope you are ok and with good health.

I was wondering if you have any advice on how could I move Archived information from urbackup to a Bluray Mdisc or a DVD for that matter.

Can I simply copy the urbackup structures for each workstation? I want to release some space from the harddrive.

Or do I need to some procedure first so the information is readable on the Bluray or DVD?

I hope you could advice me. I’m using windows server 2012 with NTFS partition on the urbackup directory and want to move some old workstation information to a M-Disc Bluray 100GB discs.

Does anybody had done something like this?
Thanks for your suggestions.

Why not just reduce number of backups or do full backups less often?
Urbackup will take care of freeing up the space that way.
