What's wrong with zfs?

>>58966724
Nothing really, but he's running a petabyte of disks split across two hosts and he's probably going to fuck it up

tl:dr it's absolutely fine, and possibly even optimal, provided you never need to expand. The moment you do ZFS becomes a pain in the ass.

he said to based Wendell that he is probably going to get a pro in to set everything up, either way, I want to see another 'its all gone' video for the funnies

As a sysadmin, I have a hard time even being aware of these videos, nothing he does is best practice.

If he really really wants to avoid tape, he should get something like amazon glacier.

Why doesn't he just offsite all of his videos to tape once a year and send that shit to iron mountain? I don't understand that.

>>58966908
Damn is tape cool again?

>>58966980
Tape has never been not cool. It's basically the best possible long term off-site storage that exists.

>>58966980
tape has always been cool - it's the goto for long-term backups

Gluben is excellent and has been around for years for exactly this purpose. It's not some unsafe, untested variable.

Then why was there a very steep sales drop in tape? I also was reading how facebook refuses to use tape for cold storage, and that was a just a few years ago.

>>58966980
Tape historically has always been used for archival and still is today with LTO Ultrium.

Right now you can get LTO-7 tape cartridges that hold up to 6TB of data.

Tape has always been cool. It has an insanely good price to storage ratio so long as you can both store it properly and don't need to be reading the data constantly.

facebook does a lot of things that are retarded

>>58967040
Yep for sure.

My offsite schedule:

Once a week - file level backups of the fileserver's most important documents, like finance, legal, etc, as well as our source code.
Once a month - files on the physical hosts, like the itanium box or the aix box stuff like that
Once a quarter - our entire virtual infrastructure
Once a year - Snapshot of state of the companies documents

The once a week schedule was on a 8 week rotation, the once a month schedule was on a 4 month rotation, the once a quarter was on a 2 quarter rotation.

This is completely separate from the nightly backups to the backup server.

I could basically recover my company from a complete DC failure to a reasonably recent state.

Not even to mention the fact that the fileserver was replicated to 3 other file servers across the globe. (this was also all tested on a regular basis)

>>58967086
How slow is data transfer to tape?

>>58967084
Because tapes have a huge capacity now and it only takes one fucking tape to backup every single document a company generates as long as they don't do something stupid like embed video files.

>>58967122
~1TB/hour per tape drive

What's not to like, it's not like you'll be needing to access tapes every day.

That's actually really good. I didn't even realize that its still in use today.

Linus doesn't know what he's doing, at all. He is literally an advertising shill.

>>58967149
obviously that's under ideal conditions but yeah

the other big benefit is tape does not degrade over time (or if it does we're talking centuries). disks do.

>>58967099
For historical data that is very reasonable. When I need to restore shit from a tape that is at iron mountain, depending on the urgency, it will take from next day to next week with the next drop off.

No reason to put 10TB of shit you will likely restore at some point. It mostly should be used as a disaster recovery, with onsite backups that you will restore from.

>>58967149
>>58967158
disk to disk to tape, I've noticed gives the best performance.

What does it mean when it says
>Capacity 1.5TB Native/3.0TB Compressed
for tapes
Because $20 for 3TB of storage would be sweet

>>58967189
It means what it says
but the tape recorder is where the real cost it

>>58967199
So if I wanted a backup of my movies in case my raid array fails, I would be able to fit 3TB on the tape? I'm not sure what it means by 1.5/3.0TB

>>58967189
Current gen tape drives are about $2k

>>58967171
Yup. Offsite tape should generally be thought of as "the building just burned down" scenario. It's a backup for a full DR. For minor fires onsites are best (like always be able to recover for the last 30 days or something).

>>58967180
Makes sense, that way the disk you're reading from when writing to tape isn't also busy with writes like the live production disk would be.

>>58967189
Highly dependent on your data. In practice it's very rare that you can actually compress EVERYTHING by 50%. Think of making zip files - for some things you can shrink the data quite a bit, for some you can't shrink it at all.

>it's a linus has his server in the bathroom episode
>electronics and power cables in the sink
>didn't even shut the mains water off to that room


it's kind of bizarre that companies give him so much free shit to advertise because he inevitably breaks it and that doesn't make the product look good at all.

Yeah and there is a lot you can do with deduping and shit like that, but it all depends on how many CPU cycles you want to put into that.

Someone please enlighten me on tape and their drives. I looked for some info a few years ago, but decided to drop it due to prices. What should be my goto? Buy a used tape drive and go from there? I have about 10TB of storage I'd like to backup.

>>58967253
>https://www.tapeandmedia.com/hp_lto_5_tape_ultrium_5_tapes.asp

LTO 5 is pretty old, I think it is up to 7 now.


>>58967244
I had a library that held 40 tapes, our larger office had a library that held 80 tapes.

>>58967253
LTO 7 is current gen, LTO 5 is very outdated.

>>58967244
Cheap senpai, if you know someone with a tape drive, or you can get an older gen cheap (just check you can use it, some have weird ports) then it might be worth it.

The older gens have lower capacity tapes.


>>58967253
>implying the drive is the tape itself

>>58967283
>>58967286
you're both right, but LTO 7 is only about $120/tape

Also I was wrong about transfer speeds - apparently it's up to 2.7TB/hour

>>58967291
Stars wearing gfuel hat, razor keyboard and mouse,

>>58967253
He is talking about the drives, not the tapes you fool.
With tape, you need a drive to put the tape in.

>>58967084

Tape capacity scales faster than its price. A company can get a 2TB tape for cheaper than 2 1TB tapes. This makes the overall market look like it's decreasing, but it's really just the per unit value. The use of tape in general is still there.

>>58967320
yup, cheapest LTO 7 drive (SAS connection) is ~$2k. cheapest tape drive in general is ~$500-$600 but is going to want a SCSI connection, and good luck with that on consumer hardware.

>>58966980
It's widely used still in corporations. New tapes drives are being developed all the time. It's the best way to archive data for large amounts.

>>58967271
I don't know if you can buy tape drives outside of bulk sales. They aren't meant for consumers at all. They mostly sell to enterprise but you could email a company and get a quote.

Isn't consistency more important than 3 fileserver across the globe, when you already have tape+nightly backups.

>>58967271
Unless you have a ridiculous amount of never ending critical data that needs to be backed up constantly, you should avoid LTO Ultrium because it's really fucking expensive.

Doing this is basically burning money because you aren't an enterprise with enough data to justify the purchase or make it worth while having in the first place.

Facebook uses DVDs because it's cheaper when they work at the scale that they are working at. For 99% of companies, DVDs doesn't make sense.

>>58967574
That's actually pretty cool. transfer speeds must be pretty bad though, reading one 100gb disc at a time. if you ever actually had a shtf scenario and needed to restore a back from severl racks it would take forever.

>>58967519
So the kids aren't his?

>>58967574
Storage engineer at a Facebook-scale company here. (Not Facebook.)

The limiting factor is almost always throughput. We use tape for offsite backup (shitloads of tape), and the biggest problem we had was the goddamned tape robots burning out because nobody expected us to run them at max capacity 24/7.

We may start using shingled disk at some point, but stranding the spindles just doesn't make sense right now.

Fucking robots, man, I glad they are not consumer tier, imagine how many problems people would have with them, they are nastier than printers. Little faggots constantly jamming, can't read cassette, get stuck physically and by their own stupid algorithms, also sticking tapes on wrong drive(that's rarely for sure) or just not properly sticking them in. One stupid faggots somehow managed to break tape by sticking it wrongly
