Thanks!

There is nothing turnkey. One thing that might be of interest is the
ability to do incremental backups via lastmod: queries. This would
require seperately tracking the output of "notmuch count --lastmod
'*'. It's not clear the extra complexity is worth for daily backups.

Personally I backup tags indirectly as part of a tag synchronization
script called "gitmuch" that I write many years ago. Others report doing
the same thing with nmbug, which is shipped with notmuch source.
