MEDIUM priority (Important overall)

3. Seed torrents for as long as possible, rare data forever. Make sure to look up a guide for your router to PORT FORWARD your torrent client port, to substantially increase your upload (and your download) speed. In low population torrent swarms, if no one is port forwarded then you might not be able to connect to each other at all and exchange any data despite having it.
Requirements: As much or as little bandwitdh you want (you can set the limits if you need to)
https://github.com/qbittorrent/qBittorrent (Recommended client, especially to replace uTorrent)

4. Archive web pages you want to have a local copy of with a "Web Extension for saving a faithful copy of a complete web page in a single HTML file with a single click"
https://github.com/gildas-lormeau/SingleFile

5. Archive videos with "GUI front-end for youtube-dl, yt-dlp and other compatible video downloaders"
https://github.com/axcore/tartube

6. "Capture or record any area of your screen and share it with a single press of a key"
https://github.com/ShareX/ShareX

7. Archive entire websites you want to have a local copy of
https://www.httrack.com/ (not sure if there is anything better than this)

8. Publish the data that you have archived that isn't easily or at all available online. The easiest way is uploading it to https://archive.org. Once uploaded and edited to what you want, you can download the .torrent file archive.org will automatically always create for all items. This torrent can then be seeded and shared with a magnet link anywhere.
You can also just create torrents yourself in your torrent client and, as long as DHT (Distributed Hash Table, decentralized way to share torrents without the need for any specific tracker) is enabled in settings (on by default), your files will be searchable on DHT by DHT crawlers, local or online (for example https://btdig.com/, where you can actually also search for FILE NAMES within all DHT torrents)

OTHER useful things:

- In your torrent client settings add the best trackers to be automatically added for all of your newly added torrents (helps more easily connect to peers, especially in obscure torrents):

- Look into running a node for I2P (anonymous private network within the global internet):
Requirements: Mostly bandwidth, more info: https://geti2p.net/en/faq
https://geti2p.net/

- Look into running Tor/Hyphanet(Freenet)/IPFS nodes.

- Look into donating your PC resources to be used more intensively in projects:

What are you archiving or want to archive?
Do you have or know anyone who has some rare interesting data or media not available online?

I wish I was as cool as you guys are.

>>101208652
What do you mean?

>>101208661
I mean with that whole archiving and donating resources. Like you are doing something for the people, unlike me.

Most of the listed tools don't take much to run if anything, even storage space.

Anything you see online that you like a lot and think might not be there in 10 years can be archived locally easily.

Setting ArchiveTeam Warrior and qBittorrent to run in the background while you are using your computer is also basically free and does most of the work automatically.
