Host It on Nextcloud

The storage bill arrives every month, the terms change when somebody else decides they should, and the files your household or your business actually depends on sit in accounts nobody can audit. Nextcloud is the way out: a file sync and collaboration server you run yourself, on hardware you can touch, that syncs to laptops and phones the same way the service you are paying for does. This guide takes you from nothing to a working instance that other people can use without calling you. You will choose an install method knowing which ones are officially maintained and which describe themselves as being for experts, pick a database you will not regret, and get past the reverse proxy and certificate work where most self-hosted instances quietly fail. There is a full chapter on share links breaking when an instance answers to more than one hostname, because it is the most common failure nobody explains. You will get files syncing to every device, connect storage you already own, and learn which routine operation on a network share silently destroys a file's entire history. You will clear the warnings panel, switch the background jobs to the method that actually works beyond a single user, and set up a backup you have tested rather than one you assume. One short chapter may save you more time than the rest of the book: the documentation page most search results send you to describes the next unreleased version, not the one you are running, and a great deal of the advice online is written from it. Written for someone who can follow a command and read a log, but who does not want a second career in system administration. Every requirement, setting and application name here was checked against the project's own current documentation, and where that documentation and the marketing pages disagree, this book shows you both.
