He could very well be using UrBackup which provides the option to compress (at the cost of extended backup windows).

Back from shopping. Read the posts. Ok, so... the tape idea sounds like this could meet my needs.
I've not used tape, how does this present its self to the servers as storage? Do you have to swap tapes manually, or are they all added in to an enclosure and available? Are they available over a network, or as USB device? What sort of throughput do you get for writing data? How does this handle modified data?

Most things compress. LTO does some crazy compression on top of that.

That would be a tape library. That's a lot more expensive, but might still be within your budget.

Yes, although SAS is the most common.

Insane. It's so fast that you normally don't do it over a network because it saturates most networks. Tape is crazy fast.

It doesn't, but you don't change data in backups, so that's not normally a big deal.

Tape itself is a "presentation" media. So your backup software would know it is backing up to tape. It's the standard by which all tape systems work, and some disk or cloud systems use tape interfaces to provide a standard so that any backup software can talk t them (Starwind VTL for example.)

We are initially going to have to use Veeam Free edition. At the end of the retention period, it injects the oldest increment in to the original full backup... is that not possible with tape?

Definitely not possible with tape. But that's just one of the many assumptions that need to be changed. Someone did your backup planning based on false assumptions. You need to back up and decide on goals and make all decisions based on those goals.
However, what you describe isn't exactly how Veeam works. Also, Veeam is a company, not a product, there are multiple free products from them. And they all work a bit differently.

So let's start with some info...
- What is the size of a single full backup?
- What is being backed up?
- What is the retention period?
- What are the goals?

Good thing that I asked, this is a case where me being pedantic really did result in the answer no one would expect. "The free version of Veeam" means this one to almost all people: https://www.veeam.com/virtual-machine-backup-solution-free.html

Veeam Agent is intended to be used as an agent backing up to a Veeam server. The Veeam server handles the tape. Here you are stuck with something much more complex because you are using only part of the Veeam system, they added some extra bits to make a free option, but the free option might cost you a fortune in hardware.

Does the version you put here allow scheduling with the free version, and unlimited VMs?

No, they are unrelated products. You get two VMs only. But it is the product that people refer to as "Veeam", and the key features that people claim to be why they choose Veeam are only in that version.
I like the product that you are choosing just fine, just pointing out that when you say "Veeam", to 99% of people it means a very different product than the one you are using. Veeam has become an industry standard meaning "agentless", even though they make agent based products like the Agent for Windows.

Does the version you posted support tape, and does that allow unlimited VMs and scheduling?

Yup, supports tape and it would be the standard way to do it. It's also the back end that makes the Agent powerful and able to do "anything." It's expected that you buy the two together.
