I would clone the second disk to the new disk (with gparted for instance) an then resize the partion to fit the disk. This way it would be a simple disk swap without needing to do anything else.
PS: I think simply copying the files will go wrong with the hard links.
They had that plan over here. But they killed it just before the war against ad block started (it was around half of the price of premium)
I get that. Thats why i included that it is a bit different for smaller creators. So yes, we cant assume there are a lot of backups for if youtube decide to go more evil. But I think of you make your money with youtube, you should invest in storing your own backups. If only for if your channel get hacked and they delete al your videos and youtube cant/wont help to restore them. And that is why i get a bit sad if a big channel says something like this, because in my eyes its very bad practice to relay on yt for your backups. ( Assuming they dont do a seperate backup amd only just rip from yt because of ease of access).
That is stupid. I get that smaller creators it maybe lesss feasible to backup. Because they don’t make enough money. But a video file, certainly if you put same compression as yt, isn’t that big. Say one gb per vid, that is 30 gb a month (say times 3 for redundency) you have less than 1tb a month, of lees than 60 bucks of storage drives a month. Small price pay for someone that has a million dollar studio to not be trusting on yt for your videos. But thay also disn’t talk about the risk of putting your 2fa in the cloud, so i am not that surprised
Sorry I wanted bit to fast. Clonezilla will clone disk including huid (which can mess things up is you keep both in the pc). But then you can boot clonezilla, clone disk (has a flag -k1 for resizing partitions), remove the old disk, and should work without changing anything else. If you want to change the settings anyway, there are more options like DD.
