Hopefully a simple "deleted item retention" question

[jcofin13]

IF you have the following:

immutable storage
sobr with immutable capacity tier

Backup job with 20 days + GFS of 4 weekly and 3 monthlys.

You you want to turn deleted item retention on.
Would setting it to 95 days be idea since 3 months could be 93 days provided we are talking about 31 days in a month at its longest?

What happens if you set the deleted item retention here to less than that or say 60 days?
Will the job throw an error or warning at all about not being able to delete the items as they would be immutable for the full duration of GFS or does GFS not apply to deleted item retention.

Hoping to find the best setting that 1. doesnt generate warnings or issues and 2. keeps the backups nice and tidy ensuring older vms that have been purged from vcenter eventually fall off our backup storage so we are not wasting money (or storage).

Deleted items retention is applicable only to regular backup chains. It does not delete data for removed machines from weekly, monthly, or yearly backups. Additionally, it’s not entirely clear how you intend to delete objects from immutable storage.

who knows. Thats the question i guess. If the GFS chains are immutable any objects in them wont be removed even if deleted item retention is turn on. Only if the deleted item retention is turned on for a number thats outside of our GFS. I guess thats my question. IF you have 1 year set on your GFS settings and set your deleted item retention on the job for 60 days.....deleted vms will never be removed.

Im not sure what you mean by regular backup chains. Would this be data that has not hit the gfs threshold of weekly, monthly, or yearly etc?
