That seems very misleading. Ubuntu 18.04 doesn't even support ecryptfs (as far as I know, certainly it isn't the default), and it was not recommended for years

That seems very misleading. Ubuntu 18.04 doesn't even support ecryptfs (as far as I know, certainly it isn't the default), and it was not recommended for years prior because it's not a very solid protection (for many reasons). If you use ext4 + luks encryption I believe Dropbox works fine. Standard disclaimer, I work at Dropbox, but I have absolutely nothing to do with product. Opinions are my own etc etc

With LUKS, you'd want to backup the locked partition, perhaps as an image. And that's just a binary file. What about ext3, xfs, etc? Encrypted files (7zip, GnuPG, VeraCrypt, etc) behave just like normal files, right?

I don't think the files get backed up encrypted, they get backed up decrypted, and are encrypted at the filesystem layer only. It isn't as if you can't put encrypted data into Dropbox, this is just about filesystems. > What about ext3, xfs, etc?

Sure, throw them into a Dropbox folder and they should upload just fine.

    Thanks for the clarification. The key issue, then, is for people running other filesystems in Linux. And especially for *BSD users. Re LUKS, I meant to use a tool that converts the encrypted LUKS volume (on this machine, /dev/md1) to an image file. Working in a USB drive, say. Then storing that 500GB (or whatever) file in Dropbox. If that's too big, then have a separate smaller LUKS volume. Or even, for VMs, a LUKS-encrypted VDI. Also, the unencrypted LUKS volume can just be ext4, for Dropbox compatibility.
