Can I restore from object storage if someone gets in and deletes backups past the immutability date?

[mvalpreda]

Say I have backups going to a SOBR and then copied to the capacity tier in immutable object storage with a 90 day immutability flag. This goes for a while and I have a couple of months/years of data up there. When doing forward forever incremental backups (with synthetic fulls), the 'initial' full backup would be long expired. If something horrible happened and anything in object storage that timed out of immutability was deleted, would I be hosed? Or is there always a way to fully restore the machine? If so, is there a way to see that in the B&R console somewhere?

Thanks and sorry for the terrible subject....

As long as your immutabilty period is greater or equal to your backup retention, all of the objects required to restore your workload(s) will be in the capacity tier and immutable.

Immutability period is 90 days. I have a backup job every 6 hours. Job is set to keep 60 days (not points) of backups and 12 weekly, 12 monthly, 2 yearly. Everything is immediately copied to object storage. Anything older than 180 days is moved from local to object storage.

Since I have a GFS policy keeping the 12 monthly, I will have 2 or 3 complete backup chains that will be immutable.

Do I have that understanding correct?
