I have fancy California Internet and the downloads are surprisingly slow and kept slowing down and turning off. It was such a pain to get my data out of takeout.

Honestly I thought you were going to bitch about them separating your metadata from the photos and you then having to remerge them with a special tool to get them to work with any other program.

I think this is a bit unfair. Most Google Takeout requests are fulfilled in seconds or minutes. Obviously collating 100GB of photos into a zip takes time.

And it's not googles fault you have internet issues: even a fairly modest 20Mbps internet connection can do 50GB in 6h. If you have outages that's on your ISP not Google. As others have said, have it download to a VPS or Dropbox etc then sync it from there. Or call your ISP and tell them to sort your line out, I've had 100℅ uptime on my VDSL copper line for over 2 years.

I was able to use Google Takeout and my relatively modest 50Mbps connection to successfully Takeout 200GB of data in a couple of days.

Find a way to borrow more bandwidth.

It's bad because they don't want you to use it, but they made it exist so that they don't get sued by the European Union.

Just gone through this whole process myself. My god does it suck. Another thing you'll want to be aware of around Takeout with Google Photos is that the photo metadata isn't attached as EXIF like with a normal service, but rather it's given as an accompanying JSON file for each image file. I'm using Memories for Nextcloud, and it has a tool that can restore the EXIF metadata using those files, but it's not exact and now I have about 1.5k images tagged as being from this year when they're really from 2018 or before. I'm looking at writing my own tool to restore some of this metadata but it's going to be a right pain in the ass.

It's not an ideal solution but you can save your Google takeouts to Dropbox. It might be worth signing up for Dropbox for one month and use Dropbox's sync features. I haven't used Dropbox in years but they used to have quite solid syncing.

You need a solid wired connection. Maybe phone a friend for help.

Alternatively you could use curl. I think it as a resume option.

Google takeout is there so they are technically compliant with rules that say you must be able to download your personal data, but they make it so inconvenient to use that practically it's almost impossible to download it. Google photos isn't a backup service so much as a way for Google to hold your photos hostage until you start paying for higher amounts of storage. And by the time you need that storage, Google takeout download has become impractical.

Can you do one album at a time? Select the albums you want to download, then do that file. Then do the next few albums. That way you have direct control over the data you're getting in each batch, and so you'll have a week to get that batch instead of having to start again if the whole thing didn't finish in a week.

I know it’s not ideal, but if you can afford it, you could rent a VPS in a cloud provider for a week or two, and do the download from Google Takeout on that, and then use sync or similar to copy the files to your own server.

Have you tried mounting the google drive on your computer and copying the files with your file manager?

It doesn't have an option to split it?

When I did my Google takeout to delete all my pics from Google photos there was an option to split in like "one zip every 2gb"

There's no financial incentive for them to make is easy to leave Google. Takeout only exists to comply with regulations (e.g. digital markets act), and as usual, they're doing the bare minimum to not get sued.
