I’m responsible for our SANs at work and there’s something else that wasn’t touched on in this video - make sure you configure email reporting from your storage nodes! The sooner you’re notified about issues, the sooner corrective action can be taken. Additionally, if possible, keep hardware spares at each site where the hardware is, so if a drive has failed (or even if it’s in a predictive failure statue), you can swap a new drive in ASAP. Same goes for other hardware, such as controller cache batteries; these too can fail, and can do so silently, allowing the node to continue working, but with degraded performance. TL;DR - Keep an eye on your infrastructure and monitor it!

That being said technical failures are ultimately unavoidable, hopefully some of that loss was transferred via insurance? Best of luck going forward y'all

As a full time Sysadmin i always wondered how you guys sustained your data without a real backup plan. As it turns out now, you didn't. Really sorry to hear that guys! That's exactly why people like me get hired. Companies think they can do it on their own until they lose critical data to misconfigs and missing maintenance. Hurts to learn it the hard way. I really recommend you guys to create offline backups to tape storage for all your archived content. And respect for admitting having it done wrong so others can learn! Keep on making such great content!

Yep. I'm doing this for 25 years now. I worked for a couple of companies with big raid systems but no backup. It's a struggle to get the responsible persons to buy sufficient backup systems. In one case only one week after installing the backup solution and having the first full backup, the main raid system failed and died. Without backup this company would have gone out of business completely. I have seen this happen to companies before.

You would need one hell of a tape array to backup that kind of data not to mention it would take forever! I don't see tapes a practical offline backup solution for this quantity of data for a company LTT's size. It is better to off have a duplicate server in a DC with clean power and resilient backups and replicate the data, that would act as backup and be a suitable DR solution. Without backups I do wonder if they have a BCDR plan in place also?

@@jacquesb5248 Nope if you have to "check" that your backups are running then you are doing it wrong. This should be integrated into your monitoring system so you get told that your backup *DIDN'T* run. Checking manually is prone to someone forgetting or been on holiday or insert a thousand other reasons. Also getting told daily that you backup ran also becomes an issue where it is seen as background noise and you get bored checking the same report day in day out. Basically being notified something is as expected is the wrong way to do anything. You need to be notified that something is *NOT* as expected, in this case the backup didn't run to completion without errors.

I worked for an MSP where they had fired the previous person in charge of backups. I was on the infrastructure team. We found that 65% of our customer backups were no good and something like 85-90% of offsite replication was failing. It was 8 months before we could return all the backups to normal and reduce the back checks workflow to less than a few hours per week. During the 8 months, it spend the first 4 working to get the backups all straightened out with almost every hour of my workday. Suffice to say, having an ops team with competent people who are organized and themselves redundant and able to check each other’s work without judgement is absolutely paramount for a team in charge of critical systems. I personally love working on backups because it’s a silent way to ensure continuity while working with amazing technologies.

Not foolproof but a good start. For bit rot, more frequent scrubbing?

I think they've covered this in the past, and the problem is that they just have so much at this point that the upload will take forever. But that doesn't mean you're not right. If anything, they should do it _now_ because every day they wait is going to just be more they have to upload. I'm sure there's something out there that will just start uploading everything in the background until it catches up. Also, IDK if it would only be "a few bucks" for the amount they need. IDK what that kind of enterprise level storage costs, but it's probably not cheap and I'll bet that even on "unlimited" cloud storage plans there's probably a catch written in the fine print with some way of restricting the storage in practice, like restricting the upload bandwidth past a certain amount of data uploaded to such a slow rate that they would never be able to upload faster than they create new data...

I'm just wondering why LTT didn't go for tape storage for their servers, since, as Linus said himself, it was for archival purposes and more of a fun project to test out the tech they got. They even got a tape drive some time ago afaik. It doesn't make sense to keep the drives spinning for years if they are not actively used or maintained.

Tape storage is cost competitive on the level of multiple petabytes, not single petabytes. So it's nothing that any significant minority of viewers will ever see in person, let alone be part of decision making process to buy, install or configure.

Because he'd rather have "dope hardware" instead of using tape. If they need access to it that's fine, every week or month or time frame you do a fresh backup to tape and keep your servers running for access and have tapes as backup. He failed to implement backup in depth which is basically industry standard. Archive is not backup. Redundant and separated storage of data is backup.

Love your show! Just wanted to chime in here coming from an IT background supporting large companies in datacenters as well as being a content creator. Trying to maintain an accessible RAID of ever growing content only gets more difficult and expensive over time. You will eventually need a full time employee to manage your content if you go this route and at some point you will need to migrate your entire content to a new RAID when 1 petabyte isn't enough anymore and that's not going to be fun. The alternative cheaper and simpler solution is to archive your content to tape which will have a much higher chance of surviving the years to come as it's not on spinning platters that run 24/7. Yes, getting access to a piece of content you want to grab on short notice will be more annoying but you can always keep a smaller RAID with your completed videos and archive your raw content via tape as it's the RAW video content that really eats up the TB which is why you might want to consider archiving your raw video.

At that density and the infrequency of the older data being updated you really should consider acquiring a tape library. A couple iSCSI targets and a 250 slot LTO library would keep you until you more than double your current use. But considering the increasing file sizes of the raw files you're ingesting I would recommend going for a 3-3.5X scaling.

Tape is slow. I think the whole point of their setup is for fast access to footage new or old for editing purposes. If they were just hanging on to it for keep sake then Tape is an option but I think they keep it so they can retrieve previous footage on-demand to splice into the current video being edited.

​@@grrkaa8450 Tape is slow, but much cheaper per TB. Typically you would have a hybrid system where users interacting with the data would hit high speed disk storage of some sort, and that disk storage would be running software that would migrate copies of files, or just less accessed files to tape. It's effectively the best of both worlds, users have the speed and accessibility of high speed storage, but the high speed pool is much smaller, and most of the archival data is on less expensive tape drives. The only time you hit a slow down is when a user has to access the stuff on tape which would be normally pulled when the user accessed a stub file representing the file on the disk pool.

Lets set this straigt: There are more backup options than local spinning disks and cloud storage. The cheapest way would be a LTO Tape-Library. An LTO8 Tape (12TB of uncompressed storage) is about 50-100€, thich is only a fraction of the cost of spinning disks. Also they are archival grade and can be labelled and stored on a Shelf somewhere. As their backup files dont really change you could just put a few projects on one tape and chuck it in the warehouse.

While I agree with the archive not being on spinning disks, long term storage of tapes is an issue in itself. It requires regular maintenance, climate controlled warehousing and copying every few years. I work in broadcasting and I have only seen deep archives done correctly maybe once in my career. I have quoted archival systems several times and the face customers make when they see the numbers and are then informed it does not include any recurring and on-going operational cost is always funny (not really).

I've noticed bit rot on my 50 TB system after only a few years and with the raid hardware being older I'm not even sure if there is a recover scrub type function. I would love for the raid to check and fix things in the background, but sadly it's a money and available hardware issue and the sad fact of being self taught due to need. This video though just showed me that I need to dig into it a lot more and actually start to look for a better solution. Thankfully we rarely see powerloss here in the area, at worst maybe a few a year due to lighting hitting a box covering a lot of houses or construction crew accidentally dig and break an important buried wire. I'm now at a point where I need more space and the plan was to add another 100 TB to the system, it's already got the connections to handle it so there's no worry there, but the bot rot issue is a worry and if there's a fix, maybe I should be thinking about going another way entirely. Only question is what other option is there that can be gotten in my country? The sad truth here is that a lot of tech is hidden behind the only professions need this limit. It's like you can only buy certain things if you work using said thing in your work. Its completely daft, but also a tiny built understandable when it comes to 240 V systems and a few other things. Then there's the local prices where a type rack disk storage cost at least 4 times more than me jury rigging my own solution that does the job, maybe not perfectly, but it gets the job done and I can barely afford doing it my self. Right now I'm stuck waiting for the local online supplier to get in enough harddrives of the type I need. Issue there is that due to covid it's been on a year long estimated delivery date... ARGH
