GFS and Immutability

[ThomasDEIF]

We have created a scale-out repository where we have a performance tier on-prem and a capacity tier S3

We have also activated the archive functionality to the scale-out repository pointing to a S3 glacier, where we want i activate immutability on the GFS data

We have checked marked the option "Make backups immutable for the entire duration of their retention policy"

Is it correctly assumed that if i set a GFS monthly to keep for 24 months this will then also be the immutability length of 24 months for the archive tier?

Hi Thomas

Welcome to the forum.
That's correct. With that setting, the GFS restore points will be immutable in the Archive Tier for their entire retention time.

Hi Fabian

Thank you for your reply

This was also as we assumed, but it is simply because it is not entirely clear in the description

In the immutability setup of the Glacier it states "Make backups immutable for the entire duration of their retention policy", but no mention of GFS.
In the GFS setting it does not say retention, it only says "Keep certain full backups longer for Archival purposes". So this is retention per say in regards of the Immutability?

Therefore we needed to be sure that this still means that when we set to keep monthly fulls for 24 months in GFS, these will be Immutable for thise entire 24 months

Hi Poul

Welcome to the forums.

On the Archive Tier, for backup or backup copy jobs we only offload backup files with a GFS Flags. Daily "incremental" restore points will not be moved to the archive tier. If you have enabled this option and you offload a monthly gfs backup with a retention end date of July 1st 2025, it will be immutable until July 1st 2025.

In the GFS setting it does not say retention, it only says "Keep certain full backups longer for Archival purposes". So this is retention per say in regards of the Immutability?

Correct. This "Keep certain full backups longer for Archival purposes" is our long term retention (GFS).

Therefore we needed to be sure that this still means that when we set to keep monthly fulls for 24 months in GFS, these will be Immutable for thise entire 24 months

Yes, each monthly full will be immutable for the 24 months.
