Hi Fabian,
Thank you for clarification.
Yes, we use LHR as performance tier and our goal is to:
- Archive 5 weekly backups, 12 monthly backups and 3 yearly backups
- Move backups from Performance Tier to Capacity Tier after 10 days and make them immutable for 31 days
- Archive(move to Archive Tier) anything older than 31 days (monthly and yearly backups)
We have Backup Copy job configured as follow:
SOBR - Capacity Tier

Can we increase "move backups older..." to 14 days? Offload job is finishing with following warning "Object Storage cleanup failed: Timed out waiting for the backup files to be released". Is it because they are still immutable?
SOBR - Archive Tier
Capacity Tier backup repository
Archive Tier backup repository
I believe we need to increase weekly backups to 6 (1st, 8th, 15th, 22nd, 29th, 36th day) to have weekly backups kept for over 30 days?
Is everything else correct?
Thanks,
AZ
