zpaqfranz VS fswatch

Now, onto files backup - if you value your data, don't make just one backup copy, make two or three. Also, I'd recommend using software that will make snapshots and you could restore whichever version you need. I am using zpaqfranz for few years now, it is command line software but you can make batch file and update the archive when needed - it will add only new and changed files, so only first backup will last long.

ZPAQ1 is great, it supports incremental backups and compression algorithm is really good even on already compressed data like images. zpaqfranz2 is a fork that adds more advanced checksumming algorithms. It's also worth looking into.

For best results I recommend the compatible fork with the latest advancements: https://github.com/fcorbelli/zpaqfranz

Or even better, fswatch (https://github.com/emcrisostomo/fswatch) which works on Linux, BSDs, macOS, Windows, and even Solaris

If you don’t mind shell shell scripting you can use something like fswatch and some shell logic to do something similar.

Well, I am not too lazy to search but I was interested in your experience, especially with reliability.

What about using https://github.com/emcrisostomo/fswatch ?

The required kernel hooks exist in pretty much any common OS these days, it is a user-space tool that is sometimes missing.

It may not be installed by default, but inotifywait is available in common Linux distributions, usually in a package called something like ionotify-tools, and has been for over a decade-ana-half IIRC. It'll work under WSL on Windows too, though only for ext4 devices not bits of the Windows filesystem made available to Linux.

I can't speak to what other OSs include by default, but as every major OS has a different API for defining how to register a lister and how it gets messages no built-in tool is going to be cross platform. There are third party tools which present more cross-platform consistency, most notably https://github.com/emcrisostomo/fswatch#readme (also available in common Linux distros, just an apt install away in Debian for instance).

fswatch is a cross-platform file change monitor. It will watch any files you specify, then run a script on change.

You can do this without polling using a util like fswatch: https://github.com/emcrisostomo/fswatch

> It watches source files, and regenerates the OpenSCAD files automatically

inotify() is awesome. Here's a library in python that does it.

There's also inotifywatch on linux and fswatch on mac. I'm sure there's alternatives for BSD Unix and Windows, but I care the least about those OS's.

For development it's easy to just ParseFiles before every Execute to be sure you have the latest version. But for production something else is needed, fx watch for changes in files and have this trigger a reload (fx using https://github.com/emcrisostomo/fswatch).
