Hi,

 

We’re about to implement Veeam Backup for Microsoft365 (VBO on premises), we already have VBR. We want this M365 backups to go to tape drives (regulatory requirements) so we were thinking on having a repository that is shared accross VBO and VBR, where we deposit VBO backup files, that is readable from VBR to do file to tape jobs. Is it possible? do you have a better architecture?

No you cannot share repos between VB365 and VBR as the file formats are different and it is not a best practice.  You need separate repos and for VB365 I recommend Object Storage for sure and you can do the same with VBR too depending on your architecture.

This is a really bad idea. You’ll be limited to working with JET which is inferior to object storage for backup (worse compression ratio, doesn’t scale nicely for starters). And when you need to restore some data from tape, even an individual item, you’ll need to restore the entire backup or a giant JetDB file at a minimum to extract the item you need.

 

What is the specific regulatory requirement enforcing tape here? Would immutable object storage, even hosted locally, not better suffice?
