What do you check when a self-hosted ebook library has to stay in Canada?

When someone wants their ebook library self-hosted, and the files plus metadata have to stay in Canada, I don't stop at putting Calibre or a Calibre-web style server in a Canadian city.

I start by listing every copy of the library: the live library folder, automatic backups, export folders, and any staging copy used to test a new plugin or a mobile app. Ebook files are one thing; covers, metadata, annotations, reading progress, and user accounts are easy to miss.

Cloud sync is the next gap. Many library tools and reader apps offer a convenient sync or "send to device" path that stores copies in another country unless you turn that off. The same goes for cover downloads, metadata lookups, and conversion helpers that upload a book to a remote service.

I also check where OPDS or web access logs live, and whether a reverse proxy, object storage, or offsite backup plugin is copying the library somewhere else. A nightly sync to another region can undo the point of keeping the collection in-country, even when the main server stays put.

Last, I ask for the data-center city in writing rather than assuming a .ca domain means the disks are here. What else do you verify before you call a self-hosted library "in Canada"?
