  • Hmm, this kind of stuff is usually a result of water acting as a solvent pulling salts and similar substances from a substrate and later evaporating, leaving the powder behind.

    It is probably something that was used to treat the plywood or a combination of that with the zinc coating of the metal (zinc-sulfate?).

    Edit: probably sodium-borate, as that seems to be prone to leaching from wood treated with it.







  • It is possible that people get access to your server while it is running via known or unkown software vulnerabilities, but that isn’t really the point… all I am saying is that if you host your server at home, it is unlikely that at-rest disk-encryption does you any good and it certainly doesn’t help to protect against illicit remote access.

    What it does “help” is preventing you from remotely accessing your own server if it rebooted for some reason… and many other such footguns that you will experience sooner or later.


  • No the Nextcloud DB is not excrypted, but neither is your LUKS file system while the computer is running. Anyone getting access to the server while it is running, can access all the data unencrypted. For a server this is the much more likely scenario than for a laptop, which might get stolen while turned off.

    At-rest disk encryption is useful for servers in co-location hosting, where a 3rd party might be able to pull a disk from the system, or if you are a large data-center that regularly discards old drives with customer data, and you want to ensure that no 3rd party can access that data from the discarded drives.
