Just a dad with a sysadmin hobby … leaving reddit
Like everyone has said there’s way better ways of doing it.
HOWEVER if you wanted to use dd you totally could. I’d recommend piping into something like gzip/zstd to save some space though.
dd if=/dev/sda | gzip >/mnt/backup_disk/sda.gz
You could also use restic backup the raw block device too.
That being said, clonezilla is exactly what you want
Everyday. I’ve got a lot of stuff that uses it. Granted most of it was mostly created a decade ago but with minimal maintenance it works great. The most helpful script is parsing megacli outputs so I can get a heads up on drive failures and rebuilds among other things.
I just came across this - https://fedoramagazine.org/d-bus-overview/ - and I think it explains it pretty well.
Yeah, I like to give some the opportunity to explain themselves so they can, hopefully, hear how wrong they are. Even if it doesn’t work that way it just advertises to everyone their views
So correct me if I’m wrong.
You’re saying, in the case of git, that people using largely text based content over protocols nearly as old as the internet itself, just like the rest of the entire world, should not be allowed to do so?
Also what’s the RFC for secondary shitting streets? I must have missed that one.
How so? I haven’t seen any evidence of that.
To add to this systemd can do everything they can. You can isolate network, do fire-walling, and sandboxing pretty easily. Any OCI container can be used too if you don’t want to install something too.
Why would you think that?
I could just do more with it.
I didn’t have a lot of money and went dumpster diving for parts. Changed out a bad capacitor and got a system booting. This was back in Pentium 3 and 4 days. I found a 512MB stick of memory that had some bad areas. Linux was able to map around it with some kernel options at boot. Since I had limited storage I used knoppix and had a print out of the needed kernel options and memory addresses.
Once it was up and running I was able to do anything and everything I wanted. I did built a better system and got gentoo going a year or so later.
Eventually I got gaming mostly working with the project that eventually became crossover. First software I ever purchased too. I started dual booting less.
I bounced back and forth between windows and Linux and when I built a system around 2010 I didn’t even bother configuring it for dual booting.
I haven’t really touched anything windows since around the release of Windows 10 and only used windows 7 for work reasons prior. These days I’m pretty useless with anything on that end.
So I’m an evangelical fan of Linux. I use it everywhere I can and the FOSS philosophy resonates with me. I advocate for it where it makes sense and works. I’ll go out of my way and spend time & money helping people move into it too.
From what I understand Greg Kroah-Hartman would take over
I was curious about this too. Definitely making me question some of my own thoughts and assumptions about btrfs.
I guess it largely depends on the instance and user. Federation allows things to talk but users and their home instances still have ownership of the data. So if a user removes it it’s gone. If the instance goes away it’s gone.
At least that’s my basic understanding. I haven’t had the time to really explore how everything works and do a deep dive. So if I’m wrong someone please correct me!
For sure!
What I’m talking about is perception of quality. If you know what you’re looking for then you’ll notice some of the artifacts. Especially in the darkest areas and when going from HDR to SDR.
It still looks better than steaming the same thing off of Netflix, Hulu, etc. So that’s all I need/want.
I fully realize there’s compromise there and if I want to view it in all its original glory I can bust out the bluray.
Yes, you’re completely correct. There’s something to consider though.
CPU encoding gives the best results possible, in terms of quality and size. Decoding, unless you have a very weak CPU, isn’t necessarily the bottleneck it most transcoding applications eg plex, jellyfin, etc.
So you can do things to make the media as streamable as possible for instance encoding your media in AV1 using the mp4 container rather than mkv. If you make it web optimized aka ATOM upfront it makes playing the file much easier and less resource intensive. Now when a client that can’t use AV1 requests it your transcode can do SW decode and HW encode. Not as efficient as pure HW but IMHO it’s a worthwhile trade off for the storage space you get in return.
You can make things more efficient by disabling subtitles and/or burnin on the media server side. If you have people like myself who need subs in everything then you can burn them in while you’re encoding the media to AV1 or only using formats like UTF8 so you can pass through them as m4v/mp4 doesn’t support subs like mkv does.
That’s essentially what the optimized versions do on Plex. Only it sticks with x264 rather than AV1.
If your media is only 720p then none of this would really make a difference for you. If you’re using 1080p+ rips then this will make a SIGNIFICANT difference. It’s made such a difference that I’ve started redoing my rips in 4K.
Unless that is you got a SAN in your closet and free electricity that is…
Yes it’s good, but with AV1 hanging about then you’re WAAAY better off using that over x265.
I re-encode all my stuff with AV1. It will take a 40GB x264 rip to 3-4GB. Where as with x265 It will be around 10-15GB.
It’s a significant difference in storage size and (as far as I can tell) no obvious difference in quality.
Good to hear! I’ve been looking at that distro too for a gaming PC. Glad to hear you’re having good results!
So yes those are things that can do similar functions and in the case of os-tree based things btrfs is used heavily.
But you’re still missing the point.
It sounds like you’re saying people are needlessly trying to be complicated for no reasons. That we have btrfs & zfs so anything else is pointless.
That’s a lot like saying we have roofs so a roof in Florida should be the same as a roof in Siberia. Anything else is needlessly complicated.
There’s a lot of nuance missing there. Sure we have different technologies that can do similar things. There’s also reasons why someone would use one over the other.
I have to disagree with you on that. You’re missing the point entirely.
It’s not about making something easy into something complicated. It’s about making something that is reliable and reproducible.
Saying it’s just bs to justify jobs, sales, etc is like saying we already have widget X therefore it’s stupid to use widget Y. You’re missing the reasons why someone might need a widget that does something different than widget x.
No one is (should) be saying one is superior to the other. It’s different technology and methods to get to the same goal. That is a working system that consistently and reliably produces results that are required.
So yes, there’s different ways of managing those systems but that’s not a bad thing or is it needlessly complicated for no reason or benefit.
There’s a lot of reasons why someone would choose or need something like nixos or sliverblue. There’s also lots of reasons someone would choose not to use them
