"Still" use tape for backup? Interesting reading about tape usage in 2020 and in future.

Some people miss this factor, more tape generation evolved more they are sensitive to humidity. It’s more than a typical disk.

Don’t miss this because some Datacenter don’t measure this. It’s crucial to don’t have a big surprise

Yes, you should schedule tape-to-tape copy after some years.

IBM and Fujifilm have set yet another new world record in tape storage – the sixth since 2006. Pushing the limits, they achieved 317 GB/in2 (gigabits per square inch) in areal density on a prototype strontium ferrite (SrFe).

So there will be a lot of development and increase in capacity in the future...

Yes, density increases very well! I hope throughput will increase even faster. Years ago I can remember we had some challenges to keep tapes streaming, now we have problems to put data fast enough to tape at maximum speed.

@Chris.Childerhose and @JMeixner That sounds interesting. What product are you reviewing and where would you position that?

I am looking at the PoiNT Archival Gateway.

Just Playing around at the moment. I will give some notes of my experiences to the community after I got some results.

And tape cloning coming in v11!  - excellent..

Could be interesting as well: What is the physical speed of tape:

  • LTO-6 @ 6.83 m/sec when reading or writing
  • LTO-7 @ 5.01 m/sec 
  • LTO-8 @ 4.731 m/sec

Interestingly, speed is decreasing from gen to gen.

The roadmap for LTO looks promising 

 

Yes it is! But you can see no doubled values from Gen8 to Gen9. Read here why:

With v11 pushing immutability this will provide a better fault domain for customers not wishing to go to the cloud route.

i love it !!!!

ultimate solution against crypto ransomware


I hope people won’t be too greedy with immutability. It’s really concrete when the linux host who host XFS is enough hardened or you will always exposed to side attack (voluntary degradation)

immutability adds another security step to complete the 3-2-1 rule.
Obviously it is always necessary to secure (hardening server) your infrastructure as per best practice.

Petabyte tape cartridges are coming down the line!

According to Fujifilm, we could see 1PB cartridges from 2035!

Awesome!!!! :alien:

14 years are a long time in IT and everything will sure evolve a bit till then, but how fast will suche a tape drive need to read/write and more important which backup storage will provide enough bandwidth? If you look at the capacity/storage ratio of the different LTO generations it looks like capacity is increasing faster then performance. So let’s say you’ll need 24h to fill the 1PB drive, then it would take about 12GB/s; make it 10h and performance increases to 29GB/s :rocket:

You are absolutely right! without enough bandwidth such a tape would not make that much sense. But it could be used as a (very) long time retention media. When you write your yearly backups to it, it would probably be OK to run for a few days. And it is at least interesting for large hoster.

Yes, but the data density increases from generation to generation and “compensates” this… :grin:

And… the tape gets thinner and thinner in each generation, so it makes sense to decrease the strain for the  tape.

When the speed decreases and the density increases from gen to gen, we will have - at a far away future - a tape backup at a point. This will be the backup-data-black-whole :joy:

A tape singularity…  :grin: 

Perfect, this is the solution for all ransomware problems, you can go back in time through the tape singularity and fix it...

I wonder if we’ll reach a point where we have deliberately blank borders on the tape to increase the material strength. Like how we saw iPhones getting thinner each generation, then we had the “Bend-Gate” drama and now iPhones appear to have stopped becoming thinner and in some cases slightly thicker again.
