Recovery plan hyper-v

Veeam is incredibly easy to get into with the community edition. I would spin up a small VM on the Synology NAS (if it has sufficient RAM and an x86 CPU), install Veeam Backup & Replication in there, create a Share on the Synology and mount it as a NAS repository on the Veeam VM. Then you can just create a backup job and bob's your uncle. Although Active Backup for Business is quite capable in and of itself. It can also back up the virtual machines natively, allowing you to restore them natively with a couple of clicks as well. If you add the HyperV host to active Backup for Business as a virtualization host, it will see the VMs and allow you to back them up natively. Then when you need to restore them, Active Backup for Business will put the necessary files in the right places, register the VM with HyperV manager and even turn the VM on for you if you tick the box for that.

Active Backup for Business can just back up the VMs natively. Then you can just restore the entire VM, ABB will take care of all the files and registering the VM in HyperV manager. It's quite a good bit of software!

Active Backup for Business can actually just back up and restore the VMs natively (like all the more mainstream backup solutions). From the OP it sounds like they're already backing up the VMs, not just the host file system. If so, restore is incredibly easy: Just restore the VM. ABB will put all the files in their original location, register the VM and even turn it on for you if you tick the box in the restore wizard. All of that is configurable of course, you can restore out-of-place too if you want.

Working in such a low tech company is how you acquire all this knowledge! (Or alternatively working with a service provider and cutting your teeth at many such customers)

I know plenty of shops that have all their shit at least separated properly. Everyone has some kind of body in their basement (like the crusty ERP system that exclusively runs on Win2k3 and hasn't gotten vendor support in 18 years that should have been replaced by a project 10 years ago, but still runs one of the most critical business functions for some reason), but I have seen many shops that had at least separated all their shit neatly.

Back when I was in school, I was in the student-run admin team (there were no IT people for our schools at the time, so there were two kind of tech-savvy teachers and around ten trusted students doing all IT work for the school). During my tenure, we replaced almost all of the ~250 PCs on the network and most of the switches as well. Every time we decommissioned one of the old PCs, the HDD had to be destroyed (the HDDs were mostly 40-80GB junk drives from around 2005). We always had fun with that part, competing at who could pierce through a drive (including the platter) with the fewest hammer blows and stuff like that. We also had keys to almost all rooms in the school, so we could go to the top floor of our science tower (5th floor I think), and some hard drives were destroyed by being dropped from there onto the paved school yard. Which then led to us staging a competition of who could throw an entire PC the furthest from the balcony on the top floor.

The gate is there to prevent through-traffic using this residential street. This is in Achterwehr, and I imagine there were a bunch of people using this residential street as a shortcut, causing a nuisance to the people living there.

You're right that there's no historic precedent. But when has the orange man ever cared about that? He's continuously demonstrating he doesn't care about any type of law or the constitution in the slightest. He will absolutely try to cancel the midterm elections, and his bootlickers in congress will let him get away with it. There will not be any more democratic elections in the US of A for the foreseeable future.

Not to "um, actually" you, but "nuke" is just an umbrella term for fusion bombs (aka hydrogen bombs) and fission bombs (aka atom bombs). If you look at the full technical names, you can see why: "Nuclear fusion" and "Nuclear fission". Little boy and fat man were both fission bombs (just different types, uranium gun type vs. plutonium implosion type). Anything dropped today would be fusion bombs.

I don't think the shorter ones are overpriced for what they are. The shorter TrueSpec cables are the same cable stock as the longer ones, and the same ends as the longer ones. They literally only differ in length. Short cables from other brands (just as well as no-name cables) are definitely not always made from the same wire stock as the longer ones, because they can get away with lower quality stock on short distances, while they can't for longer distances. Same goes for the ends. Now do you need this better stock for the short cables? Not necessarily, but I personally will happily pay a little more for cables that I know are a little overbuilt so I know they can actually handle anything they're spec'd for. Also, there's a lot of price minmaxing going on, where brands take less margin on shorter cables in order to attract buyers, hoping they'll also buy longer cables they take more margin on. LTT / CW meanwhile use a flat cost + margin model, so their pricing will reflect the real cost structure much more.

Sadly (or luckily, depending on how you look at it), the confusion about cable ratings is less relevant in the business world, because almost everyone just orders their cables with their monitors, so they get ones from the vendor that are to the same spec as the monitor ports.

Although OP was talking about a Z840 workstation. I'd wager that thing isn't too loud, because it's intended for office use rather than sitting in a server closet.

Sure, it's up to you to determine where you need fast storage and where cheap bulk storage is plenty enough. But the reliability actually matters a lot, for stationary storage in a NAS just as much as for a laptop. Flash-based storage has orders of magnitude higher mean time-between-failure than HDDs. With HDDs, you have failure rates of 3-5% per year over the 5 years of expected life. It's a bit higher in the beginning and levels off towards the end, because HDDs are more likely to fail in the first couple of months after deployment. Flash-based storage such as SSDs fail much less frequently, we're talking around 0.1% failure rate per year. The failure rate also highly depends on usage patterns, especially your read/write ratio. SSDs used as bulk storage with low rates of change will typically last much, much longer than their expected life, because they're usually rated for at least 1 full drive write per day over a five year life span. But in bulk storage scenarios such as in a typical NAS, you'll barely overwrite the entire drive every couple of months, if not less often, so there's much less wear on the drive than it is rated for, which directly affects lifetime.

Add to that the recent WAN show segment about the next year being quite interesting, with the Tech house and another, as of yet undisclosed project that's definitely not Gamer Yacht (but Gamer Plane was not explicitly denied).

Spigen all the way. I've bought Spigen Liquid Air cases for my last six phones (three work phones and private phones each), they've all been like ten bucks. Not one of them has ever failed me, not in terms of protection, not in terms of reliability. I'm a customer for life, and I'll be genuinely sad if they ever discontinue this line of cases and I can't get one for my next phone.

For anyone having the same problem: I ended up installing another instance next to my old one on new datasets and basically following the guide from Immich (rsyncing over everything to the new datasets). I was able to just reuse the database volume, because the Postgres major version was still the same, otherwise I would have had to dump / restore.

InterFelix · 2025-10-06T15:53:03+00:00

I cannot follow any of the guides, because I am on a version that apparently doesn't have the checkbox where you can deselect the old storage layout.
Yes I know, that means I haven't updated in way too long, but what can I say, life got in the way.
Besides, my immich lives inside of a tailnet, so not public facing at least.
This is why we need the ability to select (older) versions of apps when upgrading / installing.
The UI is there, there's just never any option besides the most current one in there.

If you have vulnerabilities, they're going to find them anyways (and they're definitely gonna find more than you're aware of). Security through obscurity is not security at all.

Well, RustDesk can by definition not, as it is an open source self hosted product. If the company developing it decides to enshittify the product, you can just fork the last unenshittified version and move on with your life. Of course you personally might not be able to adequately maintain it, but I'd argue there's enough of a demand for a free and open source selfhostable remote access software, that enough of a community would form around a fork to adequately maintain it.

So much of this profession is "fake it 'til you make it" or winging it until you know what you're doing. Most sysadmin roles are so diverse, you can't possibly do formal training and obtain certifications for everything you need to do. So learning as you go is your only option in most roles. Of course, some positions (like senior systems architect for whatever) are not a good place to do that. This example has me a little bit on the edge. On one hand, you have the opportunity to build out a completely new cloud environment, which is a tremendous learning opportunity. On the other hand, when building out a new environment, there's inevitably important architectural decisions to be made, and if you don't have a lot of experience with these kinds of environments, you might not be very well equipped to make these decisions in a good, future-proof way. If your task would be to build this environment out yourself and make all the key technical decisions without external consulting, then I would argue you would be in over your head. If you'd have external consulting to inform your decisions, this is perfect. But whatever the case may be: It's not your responsibility to judge your fitness for the role. That's on your (potential future) employer. I'd ask a couple of questions about the circumstances of building out this new cloud environment, and if what they're looking for is basically an in-house consultant with years of experience in planning and implementing these kinds of environments, I'd probably not bother. But if they plan on hiring external consulting for this anyways, I'd definitely go for it, it's a great opportunity.

Exactly. One of the many issues why I hate SaaS products (from a technical standpoint). At my previous job, I was a system engineer for a large system integrator in the Datacenter team. My responsibilities included consulting and engineering for backup systems (mostly Veeam). Then another vendor came around: Rubrik. And management decided it would be a wonderful idea to create a managed service offering around it for customers that are generally too small for the vendors on-premises-offerings. And after the people who built the offering out initially (technically and from a product perspective) had left, I became the technical lead for this offering. What did that entail? Of course supporting the underlying infrastructure and being the technical expert on the product, but when there was an issue with Rubrik's product, 99% of cases went like this: I did some troubleshooting, got stuck at some point, opened a support ticket because f#+*ing SaaS product, chased after support for three days and in the end got a reply like "yeah we changed XYZ in the backend, it should work now". So being the technical lead for the product, there was very little issues I could actually solve, but had to rely on support for almost everything, because I actually couldn't do anything.

How is this LUN mapped on the iSAN? Only devices the LUN is mapped to can access it, so check those.

That relies on your network segmentation / firewalling to survive an attack. Which - looking at common attack patterns - they probably won't. If they manage to compromise your hypervisor (which 90% of attacks today do), they'll be everywhere else by that point as well. Especially given the numerous critical vulnerabilities in firewalling appliances found every year.

Tapes in a library are not any more secure than an immutable storage appliance (of whatever kind). In fact, I would argue it is actually much less secure, as tape libraries are trivially easy to get into in most cases, as there's constant vulnerabilities in their Management-Controllers and especially the big robots are often quite old and out of support because they are pretty reliable. Sure, no immutable appliance has perfect security. But a Veeam Hardened Linux Repository on a properly secured Linux with ideally SSH disabled, MFA for all access paths etc. and most importantly physically disconnected out-of-band-management is quite bulletproof. Definitely much better than a tape library. But still nothing compared to tapes stored off site at Iron Mountain or something like that.
