Where to host files - under /home or /srv

It's up to you really, if you're the only one on the server there's no difference.

If you have other users uploading files then /home tends to be easier since thats where they will have write access.

Internet served files should be stored under /srv.

See the Filesystem Hierarchy Standard:

However it's your server so feel free to break that standard if you like.

I host all my site files under /rock

But Shhhhhh don't tell any of the bad guys they're there.

YMMV

I have a personal preference of saving all storage data (mail, web, FTP, projects, etc - although not DNS zone files) under /space.

The previous guy who managed the Linux servers where I work had a preference of using /brukere (Norwegian for "users"), but when it came time to reinstall some servers and migrate data from an old server to its new home, I used my preferred base path for all new and migrated data (making sure all customer scripts using a full path were using the new path in the process, of course).
