Hi guys, 

I have a question regarding the immutability in the data domain, I have a Job ( 7 days (short retention policy) and weekly for 7 weeks) I configured the retention lock with 6 days min and 14 day max and on Veeam side I set the immutability to 7 days 

What is going to happen in that case for both short retention backup and GFS backup ?

Hi Aym. In case of using Retention Lock compliance mode on your DD, you should set the max retention according to your max GFS setting, in your case 49days+ (more then your max GFS retention in VBR).

take also a look at https://www.dell.com/support/kbdoc/en-si/000079803/data-domain-retention-lock-frequently-asked-questions-faq


Paolo has also written an article on how to configure this https://www.starwindsoftware.com/blog/configure-veeam-data-domain-retention-lock/

 

Hope that’s helps.

 Best, Markus
