>about dedup, we used 200GB on the storeOnce for 1.1PB of backup data. Not bad ![:D]( "Very Happy")

Indeed, not bad at all![:)]( "Smile")
> If the backup is 8 weeks old, the immuability 14 days and GFS 12 weeks, you can't do anything.that's not what I expected, and as a teammate want to try it, sooo... one year after, I always have useless data.
Understood, this is expected with GFS as outlined here in the User Guide, the greater time period for immutability is taken.
If I get your need right, you want to have normal retention + a full backup weekly, but you don't want the full backup immutable for the entire time period?
Export Backup might be a solution for you here -- regrettably it's not a scheduled job, but you could automate it with a Powershell script for example; Export Backup is useful because it let's you set custom retention for the Exported Backup and it works entirely on the repository so no additional workload on production.
