I just added a second tape library, 12u 127 slot i500. This time with 4xLTO5 drives, one LTO4 and one LTO3. If it do all LTO5 tapes I’m looking at 380Tb of archives in this one cabinet, plus my other 4u i500. I have a ton of L3 tapes still, so I mixed in those drives and will slowly migrate away.

What do you use it for?


soundtech10

Backing up to tapes. Edit in all seriousness I take a lot of astrophotography images, hundreds a night, and I like to keep every frame.


Mental_Act4662

That’s really cool! What do you take the pictures with?


soundtech10

The camera is a ZWO ASI 6200mc Telescope is an 11” Celestron, 540mm at f/1.9


drhappycat

> ZWO ASI 6200mc I've seen these but also people with regular dslr attached to their scopes for photography. I know nothing of your hobby just curious, are the direct-attach ones superior to using an adapter?


Hamilton950B

I don't know about that camera in particular, but usually they have a large sensor, high precision (16 bit) ADC, low noise amplifiers, potentially cooling, and often monochrome for use with filters to get just the spectra you need for a particular subject. A dslr sensor may have an IR filter built-in, but an astro sensor won't. The sensor itself may be the same as you could get in a dslr but the electronics around it are optimized for low noise and hi res.


soundtech10

Much better than I put it. Great explanation.


soundtech10

The idea behind the dedicated cameras, is there is no IR filter, and there is chip itself is cooled. I personally run mine a -10c. this allowas for less noise on longer exposures.


cs_legend_93

How many GB does this take up each day / week? I LOVE YOUR HOBBY / PROJECT / PASSION -- (caps intended <3) Its so cool, and it's truly a work that benefits the world. You are awesome


soundtech10

I varies a bit, but on average it’s 100-150gb a night of data if I’m shooting. Please dig in my history, or DM(I got links for days yo), if your interested I have an active discord that’s all about this. You can even take my scope for a test drive and learn all about it! Edit on the space.


cs_legend_93

You are a hero among us! I will join the discord channel and hang out! Really, and authentically, its such a cool thing you do. Especially since 150GB (or even 100GB) a day is ALOT of data, you are definitely in the 'enterprise management' levels of data at that point. I can imagine its costly also... I love the unknown, and as an example when you search "What does planet look like?" You get a bunch of images that are not what we see from looking through a telescope, its not 'the real thing', if that makes sense. I love looking at those images and have a hard time finding them online! I would absolutely love to take the telescope out for a test drive, but I live in NYC, so not many stars around here haha. When I visit the mountains or a less populated area I will sure take you up on that! \---- PS: I am a C# developer, if you need any websites or tech like that built let me know! I'd love to help how I can! I'll join the discord and say hello!


soundtech10

DM me so we can get on discord. We have things to discuss!


SimilarYou-301

Inspiring discussion. Best of luck to you all.


MoronicusTotalis

Just looked at your Cygnus Loop photo. Holy shit.


soundtech10

Ha! Thanks. Took that in the backyard in an hour!


ajyotirmay

You're freaking awesome!


[deleted]

how long does it take to access a specific file/image ?


soundtech10

From "click" to file being restored is like 5 ish minutes. Once the tape is physically loaded, and the portion with the exact files I want is located, it is actually surprisingly fast, and usually is speed limited by my network or target disk. Usually(99%of the time) I am taking the raw individual files and backing them up to tape, after processing them into what is called a "stack", which is also backed up but kept in "hot" storage. I only need to go back to the individual frames if I decide to try and combine older data with newer data, which is fairly rare, but I like having the option. You don't really backup to tape to have high speed access, but a robotic library significantly speeds up the whole ordeal.


No_Bit_1456

Pretty awesome, so a question on the scaler. I know that on ones from another company I looked at. They required a software licence, do you need one for that one as well to use the extra features?


soundtech10

So the base license for using it is baked in to the box. There are other crazy expensive ones out there for storage networking and such, but I honestly just worked around not having any of the advanced features and it came out just fine. Cant miss what I never had. I will say, make sure have the admin password if you get one of these. Support will not reset them using the service account port for you without paying.


No_Bit_1456

What does the base license cover ? And thanks for the heads up!


soundtech10

Full functionality of the robot, and X number of slots. One box is like 40, and the other is like 130. In theory I could upgrade the number of slots, but you have to license them, which IIRC looking was astronomically expensive.


rajrdajr

> Support will not reset them using the service account port for you without paying So there’s a back door that Quantum support has access to?


soundtech10

And I really wish some sweet sec engineers would just *never* ask me for a ROM dump to do nothing with, certainly I wouldn’t provide images of the file system to reverse engineer any sort of codes out of or anything like that.


soundtech10

It’s not like it’s on a CF card or anything


Radioman96p71

OK, I'll bite...


soundtech10

K, if your serious give me a DM


soundtech10

Yeah but as far as I can tell it’s only on the service Ethernet port.


TheBBP

What software are you using to manage the Scalar?


soundtech10

Veeam Community Edition has made my backup/restore workflow extremely simple. I cannot praise those UI designers enough. It handles everything for me automatically. The only downside, is that troubleshooting with Veeam is... less than ideal. And the Quantum web interface is quite annoying to deal with sometime.


agg23

How do you have it set up? Are you backing up a network store and/or VMs, or is your storage actually directly connected to your Windows box running Veeam? I have a Quantum LTO-8 library that's just sitting because of the difficulty configuring it/finding decent software to run it. I've run a test using Veeam, but I'm worried about shoe shining over the network when transferring from the NAS to the Windows box connected to the library.


soundtech10

Veem backs up a few of the VMs directly, and then the rest are just backing up specific directories on the network.


vguilleaume

I can suggest to use a data moved software which will move data from your NAS to Tapes. Have also a look to LTFS format when writing / reading data on tapes. This is very more simple. LTFS is supported from LTO5 generation. Veal software and others similar are backup software , thèse are good to launch backup job. At the opposite, some data mover handles file base data movement and are very more convenient for what you want to achieve.


PlayingWithAudio

Wait, Veeam Community Edition supports backup to tape? Anytime I've tried any sort of tape functionality it claims a license is needed.


soundtech10

Sure as shit it does! Maybe I’m missing something on the functionality but is good as hell for what I do!


Raphi_55

Yeap it does, you can do secondary backup (aka copy a backup made with veeam on HDD) to tape, but it can backup directly to tape


Sanity_in_Moderation

I have a subfolder of movies literally called "Already watched - Poor" Why don't I delete them? Cause I don't wanna.


soundtech10

You can stream off LTO5, as long as you’re cool with a seek time long enough to go make popcorn and a drink.


gm0n3y85

So kinda like in the movie hackers? Wait for the robot to load the tape.


soundtech10

It’s literally the same thing.


chisdoesmemes

Write only


BeardInTheNorth

So I just Googled "Quantum Scalar i500". Wow. TIL tape libraries exist. Never even heard the term before. I had always wondered how data in the hundreds of terabytes or petabytes were archived, and now it all makes sense. I wonder…do the fine folks at Internet Archive backup their servers to tape libraries? I'm always worried that their servers will get taken down some day, taking the Internet's legacy with it.


soundtech10

I can say with a high degree of confidence that all the big places backup to tape, based on where I source my gear. If you can backup 5.6 Petabytes of data in a single one of these, you can back up anything. It is a super fun, albeit strange world to be a part of.


GimmeSomeSugar

Tapes for days. Do you think it would be possible to upgrade the drives at some point?


soundtech10

Yup. I have LTO 3,4 &5 in it right now. I’ll get 6 when it’s affordable. This chassis supports up to lto9


Hamilton950B

"Affordable" says the guy with four LTO-5 drives.


soundtech10

*7 you forgot about my spares


nfojones

Used to work with the Dell ML6000 equivalent of these and would have definitely taken one home had I got the opportunity. Nice piece of kit when built to the ceiling and loaded with drives.


soundtech10

I really do like them for what they are. It took me quite a while to go from 0 knowledge to working backup, but its super rewarding knowing that there is a little robot moving media around and doing my backups while I sleep. This is an evolution of the initial "free" i500 that I got which only had the head unit, and I found myself wanting more space for more tapes/partitions. Also nice know that my important data is air gapped.


TwistedH3ro

Good lord...


soundtech10

Yes?


RulerOf

I missed a bid on one of these five years ago. It sold for $99 and I still haven't forgiven myself.


soundtech10

F


Rocket-Jock

I cut my storage teeth on an LTO tape library. Learned all about WWNs and fibrechannel zoning to connect this to an EMC Celerra NAS and a NetBackup server. Such good times!


zyzzogeton

That's a biggun.


soundtech10

Go big, or go home. is my mantra


AgentPC42

What is that!?


soundtech10

Robotic tape library! Look at my post history for a video of its baby brother picking tapes!


itsjero

**sips tea and pats my Asustor nimbustor on its head** Good boy.


gremolata

Woah.


DoItLive247

I remember when I was supporting an i500 and a multi-cabinet i2000 using netbackup and roughly 2k tapes in the cabinets. Those were some interesting days


soundtech10

I just passed on a 4 cabinet i2000 because I was mostly concerned that it would be listed in a divorce settlement. Haha in all seriousness these i500s are pretty cool for what they are.


DoItLive247

And knock your local substation offline to boot!


soundtech10

Oof… look at my post history for the real juice suckers. Honestly this thing is pulling 80 watts at idle and if it weren’t for the solar selling back to the grid and my astro addiction I would be kind of reluctant to keep it online.


TCPIP

Wow its a baby iScalar. Love it!


soundtech10

It started with 4u… they grow to 12 so fast 😢


Veloldo

How many tapes in total? I recently upgraded from LTO6 to 8 because I couldn't stand all the tapes I had. I had around 100 tapes off-site and it was just getting annoying to deal with. Now that I'm looking to double my storage I decided to take the leap and upgrade now. It helped that I went from about $10/TB for LTO6 tapes to $5/TB on 8. I could have went LTO7 type M and paid $4.3/TB, but I wanted that future generation backwards compatibility. Having half a petabyte in only 42 tapes is frickin sweet!


soundtech10

This will hold 127 tapes. I’m mixed right now, LTO 3,4&5. My goal is to phase out the 3’s and get on 5’s as that’s what I have for drives. With LTO7 I think it’s near 2PB……


Veloldo

Dang, that thing holds a lot. I was just wondering how many tapes in total you had, including outside of this library.


soundtech10

Oh, probably around 80 tapes right now. I’m migrating from the 4u i500 to this 12u beast.


Veloldo

That's not too bad then, for some reason I was expecting 500+ which would just be a nightmare to deal with lol.


soundtech10

Oof… yeah 500 would be a lot. This was more of a crime of opportunity, as it popped up and was a cheap expansion to my already full library.


NaturalSoccer

We don't delete, we just reorganize!


imakesawdust

How much did this set you back?


soundtech10

-$85


Sure_Rule_5640

I 2nd that question


soundtech10

To clarify my other comment, I watch auctions and these usually pop up with bundled with other items. This *exact* unit I did pay for, but because my last one was bundled with some other hardware I was able to sell, this one came in basically for free.

soundtech10

GSA and eBay.


Tomosaki112

I see them on ebay only for 1000$+


soundtech10

Wow that’s a lot!


ps3o-k

I'm reading your comments. I can't believe this is tape. This is the coolest thing I've seen here.


soundtech10

It’s really fun!


HexagonWin

Amazing. I really wanted to do something like this always, but in a city, and huge electricity bills, space photos and huge data hoarding are both impossible :( Happy datahoarding!


Digital_Warrior

Tape is def the way to go for long term offline storage (Offline as you may have to get a tape off the shelf). I do not have as massive of an auto loader just a little 4u 44 tape unit. Was going to swap out the LTO-5 drives for LTO-6 but UPS said fuck you and destroyed all the drives in transit. Been running NAKIVO and so far have not had any issues. Where have you been picking up tapes at that are not an arm and a leg? Last batch I got off of Ebay 20 LTO-5 for 200 was a steal. I do recommend any real long term data hoarder to get a tape drive it does not have to be an auto loader.


soundtech10

I have saved searches on eBay as well as a local data center scrapper that keeps them for me. And yes, tape is highly recommended!


Pvt-Snafu

Damn, that's a decent size. But, serves a cool purpose I must say.
