Air Gap Backups

Now I understand that bit it makes more sense, as to me air gap would be things like tape
Tape is only gapped if it is manually removed from the tape device and a robot can't put it back in. Many small businesses use tape in a fully coupled way. So you have to be careful in both cases.
The problem linguistically is that when we talk cloud, we assume that the storage is mutable, but it might not be.
And when we talk tape, we assume that the tape is immediately removed and stored somewhere that cannot be accessed in an automated way, but it often isn't.
So there is a lot of assumption that goes into talking about it.

couldn't you just backup to something that can be shutdown by the backup app once the backup is complete?
then just add powering the device back up as one of the daily tasks to be undertaken by the sysadmins or whoever.
you used to be able to get those 'cassette' drives which were just disks in a casing that were used in a similar way to tapes. maybe there's something similar to that with a capacity of 1TB+ ?
if you work in a 24x7 centre maybe you can get one of the night sysadmins to just unplug the backup medium once the job is complete?
i did that years ago at a place that had mainframe admins 24x7, they just added it to their nightly tasks.

Sure, and tape is the easiest form of that. You can use removable drives or whatever. They are shut down and disconnected.

If you power it back up, it's not air gapped.

Sure but... why? Tape is cheaper, faster, and more reliable.

Right, but again, tapes are built specifically for this. Eject on finish, have the wetware come and pull the time sometime before the next shift and insert the new tape before the backup window starts.
Yes, you can use anything instead of tape here. But tape is purpose built to do every aspect of this as perfectly as possible.

Essentially every company of any size does this. It's a super rare large firm that doesn't have removable media that needs to be taken to storage daily.

But neither is the tape while it's inserted in the drive.

The only part I might disagree with is cheaper. tapes are super expensive, though in the long run I suppose they could be cheaper.
LTO drives start at $2K and most single drive bays are more like $5K+... but I know those "drives as tapes" solution from the 2010's weren't cheap either...

Yes, the drives are a large one-time up-front expense. The media is generally cheaper than HDD of the same size, which is just one reason why tape is often the preferred medium for air gapped and/or offsite backups.

Boy they must have come down...I recall when LTO 2 (yea a long time ago) where stupid expensive!

LTO 2? Bah, young people will never know the joys of DLT.

But neither is the tape while it's inserted in the drive.
But you eject tapes, no human needed. The system, by default, auto-air gaps.
The difference is culture. When people use "turn it off" technology, they mean "and then turn it on again". When people use tapes they mean "eject and take to storage".

Find me something cheaper. No backup is cheap, but there is a reason all cold storage uses tape... nothing comes close in price per GB.

No, they weren't. You just felt that way because you didn't have to price out a comparable alternative. Everyone imagines that they are expensive, but when you compare against other options, they are cheap.

Cheaper to buy, cheaper to transport, cheaper to store, last longer.

Since we are a SMB we used to use Tape (well RDX), but with people leaving the company, relaying on people to remember to take them home, put the right ones in
I hoping they will change their software soon so i don't need to worry about it

Tape dropped below $.01 / GB seven years ago and is cheaper now as new tech has come out.
Hard drives are still more like $.02 today. So hard drives are more than a decade behind in pricing as a starting point.
(That's about $8/TB vs $20/TB)
And that's enterprise, archival tape that is screaming fast vs. cheap, crappy, consumer SATA drives that are dog slow. So we aren't talking apples to oranges. We are talking tape Ferrari vs. a disk Yugo.

There are services for that. But if you use REAL take instead of disk, the eject function makes that so much easier because if they don't take it home, you get alerts that the tape wasn't changed.

I thought RDX did the same?
or could at least?
