As previously discussed, this issue is twofold:

 - upstream chromium stores parts of its cache in the profile folder
(that's https://bugs.chromium.org/p/chromium/issues/detail?id=1106754)

 - the snap format enforces that apps' cache folder is under
$HOME/snap/$SNAP_NAME/common/.cache

The first point equally affects all packaging formats (including deb).
The second one is a design decision for improved security that has its
downsides, particularly (as pointed out in the last few comments) with
regards to backup solutions that want to exclude one single cache folder
in the user's home directory. As a mitigation, can your backup tool
exclude folders including wildcards, e.g. -$HOME/snap/*/common/.cache ?

Title:
  chromium-browser does not follow XDG base directory specification

Status in Chromium Browser:
  Invalid
Status in chromium-browser package in Ubuntu:
  Opinion

Bug description:
  Currently Chromium does not follow the XDG base directory
  specification which means that the cache and configuration folder
  aren't properly used.

  This causes the issue that it's nearly impossible to properly migrate
  or back up Chromium configuration (between computers) and it makes for
  example mounting cache as tmpfs or wiping it very very difficult.

  I felt those both immensely when trying to migrate my home folder,
  gigabytes of cache in ~/snap/chromium/[id]/.config/chromium/[folder]
  (and ~/snap itself is also not XDG base directory specification
  compliant, shame!).

  There's also the issue that the previous configuration that is located
  properly, isn't migrated by the migrational package.

  In order to fix this bug, it would require making the snap package
  follow the XDG base directory specification.
