I think it would be reasonable to add an Always-on exclude of ~/snap/*/*/.cache maybe. Doesn’t help for snaps that put their cache somewhere else... but that will get the majority of good actors.
I don’t know what canonical’s plan for a program like deja dup to programmatically determine which snap folders are worth backing up / which are not. But we could do this hack until they have something for us to use.

With the introduction of snaps, the cache of the snap apps is stored in ~/snaps /APP-NAME/VERSION/.cache. Unfortunately this means that Deja dup can't be configured to exclude these directories from backups. Since 2009, there have been several requests from the community to add support of advanced include/exclude support in Dejadup but there is no progress. Do you have any plans to provide minimum support for excluding specific snap folders such as .cache?
