Because that many TB cloud storage is crazy expensive for an SMB.
Um. . . crazy expensive to compared to having your 1 and only working backup system die when you need it and then the business is done for?
At B2 the price is pretty flipping cheap per month.
How expensive would it be for the down time required to download that much damn data? Or wait to have it shipped if they do that?
Who says you need to download the entire thing? And in the worst case B2 will ship you a drive with all of your data that you'd just plug in and pull off of directly into your file share.
You said that when you said the production filer server(s) take a dive. That implies the whole lot.
Fair enough, but at the same time a production server taking a dive (depending on how the environment is setup) could be hosting iscsi shares into a hypervisor with a small-medium share of rarely-occasionally used data.

Which would hardly be "critical to need constant and immediate access to backups" in most cases.

The tapes alone to here outweigh his budget assuming he bought only 14 tapes!

Yeah, there's a ton of "coulds" when nothing was really specified.

that's the DRIVE, not the tape, lol. He only needs one.

LTO-7 are $74 each. They are 6TB raw, 15TB assumed compressed. So to get 200TB it would cost...
$74 * 14 = $1,036
If they wanted to do off site, you could get 200TB of on site capacity, and 200TB of off site capacity for just $2,100 in tapes and $3,650 in drive. And that's an expensive drive, you can get a nice Quantum for a little less.
If backup storage was the only need, you could do it all for under $4,000 USD, maybe around $3,500 USD!
You could do something pretty awesome for the kind of budget that they are talking. Hence why I'm flabbergasted by the combination of "not doing it enterprise" with "tight budget". The "normal" approach to this that is more reliable and flexible is so cheap.

The backups are already compressed via the backup software, such as Veeam. Veeam does great compression, so you just get the raw capacity on the tapes. So 6TB of backup data per tape. However, that 6TB may contain like 10TB of non-backed up data for example.

You assume!
-
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.
-
@Jimmy9008 said in Raid10, must use or another Raid limits?:
How does this handle modified data?
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.
