I hav a question about retention of a job that sends backups to a immutabble repo (like object lock repo or linux hardened).

 

We need to use forward incremental in this case, but do i need  to make more than one full backup file during the locked period? 

 

Example: a backup job forward incremental with 14 days retention and one syntetical full weekly, sending to a object lock s3 repo with 7 days lock retention.  In this case, do can i use 7 days and one backup full in the first backup job task? 

You have to keep in mind that if you set retention in the S3 that will play in to the length of the backups being retained.  You are better off to use Veeam to control the entire retention.

See this link for explanation of retention - Short-Term Retention Policy - User Guide for VMware vSphere


Simple answer...maybe; depends on your needs/goals. You do have to make an occasional Full, thus how Fwd Incremental works. You have to make a Full at least weekly as there is no option (that I recall off-hand) to make a Full other than that (bi-wkly for ex.).

Also keep in mind, Object Immutability and Hardened Repo (block storage) immutability work a bit differently. Block-based (Hardened) immutablity retention works by the immutablity period starting after the last backup file in an active chain is created. If your immutability is config’d for 7 days, then after the last increment your immutability time period starts. Immutability happens after the 1st backup file (Full) is created, but the 7-day period doesn’t begin incrementing until after the last file in that chain is created. Make sense?

Object Lock is different as you have extra days (10 or 30 days, depending on the Object Storage type) that gets added. This is called Block Generation. You can read more below:

So, if I have 7 days retention on the Backup Copy job that copies backups to an object-locked repository, will I store the first 7 days of the active chain (one full backup and 6 incrementals) + 7 days of immutable retention (one full backup and 6 incrementals) + 30 days of block generation?


That sounds correct ​@jaudir cruz ..and 30 days additional, yes, if you’re using AWS or IBM-based Object.

The block generation will depend on your storage type that you are using and you will need to check the settings there, but essentially this is how it works.

Lol, this seems very impactful to me because I always used the 7 days of immutable retention thinking it was just 7 days! and when i try restore in console, only see 7 days available... Is there any exception? For example, I use S3 Standard. My disk consumption doesn't seem to support 30 days + 7 days + 7 days...

It can be impactful yes but again it depends on the vendor you are using and the S3 settings, etc.


If you go into the Home node > Backups > Backup Copy. Find a given Job in the working area which goes to Object and rt-click it > Properties. If you select a backup left, you should see an “Immutable Until” column in the bottom window. That should tell you the length of immutability period for a given backup file.

i see it some

Hmm...ok...I don’t see the ‘Immutable Until’ column in the bottom Window of your screenshot. I guess it’s not a feature for Backup Copy Job properties.

You have Veeam set to 7 days - now you need to check the settings on your S3 bucket in the console of whichever vendor you are using.  That will tell you and is something we cannot check.

My AWS S3 bucket is simple configured with object lock, it is an s3 standard. But, who creates the Block Generation is not Veeam?

Ok but I don’t know what vendor you are using so you need to log in to wherever the bucket is and check the settings there!

My Vendor is Amazon Web Service!!! And my bucket is a simple bucket with default configurations, in the Standard class. 

 

I found this article about this: KB4470: Increase in API Calls when Performing Direct Backups to Immutable Object Storage

 

Can i disable it?


You can try it and see.  This is one of those implement this and see what happens if problems revert it back.  Make a backup before proceeding.
