The problem is they are almost never good, as everyone can read the same info 4x faster than someone can present it (best case), and 10x faster isn’t unusual.

Source: Former technical trainer - I’ve read a lot about instructional methodologies. Video is the lowest common denominator that’s all. It can be useful for things that have a visual component, and self hosting has very little of that.

Seems there are 2 kinds - video links with almost no text, just farming visits, and video links with a wall of text.

Both suck. Videos, in general, suck.

So much of what goes on here needs text, lots of it. Video is slow and cumbersome.

Define share?

Keep all files in sync between two points?

Enable ad-hoc access to all files, or a subset?

As others have said, sync isn’t backup.

It may be part of a backup plan, however.

I use Syncthing on my mobile devices to keep data created on the devices synchronized to my server at home. Things like photos sync to home over any connection, while I sync other stuff only over wifi. Syncthing-Fork allows you to set these conditions on a per-folder-pair basis.

That server becomes my authoritative box for any data. All that data is then mirrored on a schedule to 2 other systems at home (a NAS and a large drive on another box).

The main server also has a cloud backup which runs continuously.

So I have 3 local copies of data to recover from if I have a hardware failure, and a cloud backup.

I find tools like Syncthing and Resilio are good for synchronization, especially mobile devices. But between full-pc-OS devices, I just use native tools (scripts and schedules) because I don’t want synchronization, but specific patterns of copying/mirroring, etc.

I do use Resilio for ad-hoc access to almost any file on my server, since it’s Conditional Sync feature permits me to connect with a mobile device from anywhere and sync only the selected files. So I can grab a movie or TV show, Resilio will sync it and I can watch it once the sync is complete.
