Hi there - installed the product on the host (new computer), registered exactly the same cloud storage account. Selected the same AWS bucket, specified the same prefix via advanced settings. Sync process occured.. Went to Backup Storage and nothing is presented. I have not configured a backup plan.

I don't see the file structure as per the old computer.

I also downloaded and installed the MSP Explorer Pro to check cloud side drive folder setttings and I do not find a drive letter.

Thoughts?

Can I assume you're talking about the image backups? I assumed you had file backups as well. I'll check with the team, but I'm pretty sure there's no way to preserve the image backups on the new system since the drives are structured completely differently from their physical counterparts.

So, I confirmed, and as I suspected, you cannot continue image-backups once you perform a restore to a new system or VM. Backups are block-based and tied to hardware IDs of the disks and that means you'll need to start fresh on the new server VM. You can, however (and obviously), keep the original physical server image backups around as long as needed until you are ready to remove them permanently.

HI David - sounds perfectly reasonable. I'll circle back with my team and share your observations.
