Hi Guys,
i have few question about the Veeam immutability feature with Storeonce:
.
1.in a backup chain the metadata of the backup is stored within backup, if we enable immutability, it prevents modification and deletion, so how this is handled assuming we are using forward incremental + synthetic backups?
2. Is immutability only configurable on backup repository (inside catalyst stores), is there a way we could enable it per backup job?
3.what happens to the retention policy setting we set on backup jobs when we enable immutability since immutability prevents from deletion?
regards,
LB.

Re: Veeam Immutability + Storeonce
Hi LB.
When you use a shorter retention than immutability, the backup server won't be able to remove the restore points.

Metadata is stored in our VBM file and in the backup files itself. The Metadata file is not set immutable. Only the backup files are. Therefore we can update metadata for the backup.1.in a backup chain the metadata of the backup is stored within backup, if we enable immutability, it prevents modification and deletion, so how this is handled assuming we are using forward incremental + synthetic backups?
Immutability is set per repository. If you need different immutable periods, you need to use different repositories. Please note that GFS backups are made immutable for their entire time period.2. Is immutability only configurable on backup repository (inside catalyst stores), is there a way we could enable it per backup job?
Nothing. It's a different setting. It's recommended to set the retention time higher than the immutably period setting on your repositories.3.what happens to the retention policy setting we set on backup jobs when we enable immutability since immutability prevents from deletion?
