Tape backup advice ?

Why Tape, it's slow, difficult to transport and requires human interaction.
Well, two out of three ain't bad.
Tape is fast as hell, plenty faster than anything you got for a pipe:
https://www-03.ibm.com/systems/storage/tape/oem/lto6/full-high/specifications.htmlDifficult to transport? I can throw an LTO cartridge across the room and it's ready to go. It fits in my pocket, and really don't need much effort to put it in a box and have someone pick them up.
Human interaction is a real concern, but that's what you pay smarthands for. I would have a guy come by the DC once a week, pull out an entire tray of tapes from the library, replace them with fresh tapes, and be out the door in minutes.

@PSX_Defector you have to account for the travel time.
Sure tape performance is fast, but the pyhsical transport is slow.
Hand carrying it poses risks as well, like risk from a natural disaster. The goal is to have a geographic separation beyond an hours drive.

we have issues with tape: no one wants the burder and responsibility of managing it. and company don't event provide insurrance for accidental damage of copies. tape managed by external company could be ok, but they ask -of course- lot of money for picking it . So offsite is going to be on a remote site for us (could or colo where we will place other stuff).

Tape advice: use 3M 996, 2 inch width at 30 IPS. No Dolby noise reduction. Align to 250 nWb/m^2, then drive the shit out of the levels for rock music.
....oh, you meant backup tape. advice = don't do it.
If I don't want to go for cloud option, and needs to take backup to offsite, so do you people recommend External hard drive as a replacement to Tape ?
Isn't offsite tape a form of cloud? Cloud in this context is just another word for offsite.
Repeat : Not sure, how secure the cloud one will be in case of viruses, while in case of moving Tape or External HDD to offsite will give us peace of mind (no connection, no virus).
Let's say if I have resolved the issue of Bandwidth by increasing, how about pricing for Cloud ? and not sure, how much space I should buy ? maybe I need to test it by Free Trial if they have ?
Which cloud option do you suggest ? I think, Amazon Glacier is not suitable, as its for Cold Archive.

Push your backups off site to an online storage provider like BackBlaze or Amazon or Azure or anything else.
Tape, while cheap, still requires an upfront investment in hardware, using online storage does not.
If that's the case, how it will be I replace Tape with External Hard Drive ?
About Cloud, I am afraid of Bandwidth, we have 40Mbps down and 10Mbps. By the way, how you prefer to push the data to Cloud ? directly from Server to Cloud with some Agent or from Onsite Backup (QNAP NAS- my case) to Cloud with addons ? if
10mb/s will definitely make cloud storage options hard. Have you looked into increasing that as an option?
Yeah, I may need to check about options and cost we have with our ISP.
How about pushing the data to Cloud ? directly from Server or Onsite backup storage (NAS) ?

Depends, they talked about that at VeeamOn. With something like Starwind VTL on Glacier, the access time to retrieve is so slow that there are ways to effectively intervene before ransomware would successfully get your data.

Slow in what sense? It's screaming fast in terms of Gb/s.

Then use robots, that's what big companies do. No human interaction needed. Stick a robot in your datacenter and voila.
IBM was showing off their insane scale robot at VeeamOn, it was nifty.

You are aware that Amazon Glacier is tape in the cloud, right?

No one does free trials of storage. Since you way so little for what you use, there is no reason to. And you don't buy space, you use what you need.

Is that not what this would be? Tapes are cold archives already. So if Glacier isn't suitable, is tape suitable? They share that designation.
BackBlaze B2 is cheaper than S3 and we really like it.

The physical transportation from offsite storage to onsite recovery. It is slow in comparison.
Highways speeds maybe.
You quoted me, but clearly didn't get what I was saying.

But that's normally far faster than cloud. How long does it take to pull down 6TB? How long does it take to drive a 6TB tape from 40 miles away? And tape scales, the time to retrieve 6TB is the same as retrieving 600TB.

That's what you pay Iron Mountain for. They have vaults that can withstand just about anything you throw at it. Short of a nuke going off in the city, then you have other problems to worry about than where your backups are.
Sneakernet throughput is insane compared to most affordable pipes. It takes about 2 hours to go through a tape straight stream. LTO7 holds 6TB/12TB. Even factoring in the transport time of ~4 hours after pickup and 1 hour to put it in a box, you are looking at ~550Mbps with full 2:1 compression. I can sustain that speed from two of my DCs, but hell if I want to send it across to London or Singapore.
Let's not forget about the fact that you are stuffing the pipe with all that traffic. I doubt most SMBs have even the ability to get a 10Gbps pipe I got. My 10Gbps pipe is not dedicated to our DR product, but all traffic. So even if I was replicating 6TB every 6 hours, I have plenty of room to allow others to do things. With most SMBs, they could hope for a 20Mbps up, but most are running on commodity turd pipes with shittastic peering which slows them down.
Of course, this all predicates on what exactly you are backing up. I have 4PB in one DC alone. Tape makes sense. Most SMBs, once their digital packrat tendencies has been culled, don't have even enough to fill up an LTO4 tape.
Cloud backup for small datasets, tape for large.

Yeah, like your data being on tapes that are too hot to safely handle

And that is one tape. Tape really explodes when you need more than one. Say your backup spans ten LTO7s. Then suddenly you are driving around 60TB / 150TB at the same speed that you were driving around 6TB before. Until your restore size is larger than what fits in a minivan, tape just scales up "for free."

I would trust Azure or Amazon cloud in the security aspect a huge amount more than any datacenter I would secure myself with a small team.
These places invest tens of thousands of man hours and the skillset of hundreds of experts in keeping the cloud secure and in working order.
There's no way any of us can say that about our own environments, no matter how skilled you are.
So these people who won't store data on cloud because they don't trust it more than their own environment because they didn't build it is a misconception.

Even if I worked for a Fortune 500 with a dedicated security department, I'd still trust them more!

It's the "illusion of control."

Same problem as when driving a car feels safer than riding on an airplane.
