Feature: Picking individual files out of Backups

[ErrinDev]

Hi there. A common issue i see people having with pterodactyl's backup system is having to download a whole backup to get one file. I'd like to implement a system in pelican that lets you pick a file out of a backup, and just download that.

I'm not 100% sure on the implementation yet, but I'd use a second file to act as an index for the tar, so that a file browser like interface can be presented as soon as someone wants a file, without needing to decompress and scan the tar sequentially to find all the files. I am open to also using a database for the index, if that would be preferred.

Let me know if this is something you'd be open to me contributing! I'm already working on a system like this for pterodactyl as an addon, but would be cool to get it included in base pelican.

My justification for this is that it's tricky to do full incremental backups for servers, but this would provide most of the function that people are after when they suggest that. This would allow you to go back a day and pull out just a config, or just a data file that you need!

This feature would help a lot. Mostly I do not need all files to be restored and therefore I have to kinda reset to an earlier state... Picking a specific file/ folder would be a good addition to the current backup system.

Yep, I keep having, and seeing other having this issue! If i can't get it included into base Pelican I'll be making it a plugin anyway, so you could still use this.

A plugin would be nice too, if they won't add it

It would be really helpful. Like when server runs out of memory, and files cannot properly land on disk. A few days ago, I ran into similar situation. Server is about 50gb, downloading and extracting such big .tar would be a pain for server owners.

Thanks for your work on plugin! Waiting for release, though.

Would be good to know the scope of features in the base panel vs what should be plugins. Could any maintainers comment on this? I could see this feature as either, as it goes beyond the base function of backups, but significantly improves the system. (In my opinion)
