Makes sense; OTOH we also use Seafile as webdav storage for synching with DTTG.
For smaller amounts - like a database with 50k mails in it - the direct sync DT ↔ DTTG that I just did for a new DTTG customer is very good and fast. Another database where I’ve several hundred thousand mails in is still synchronizing after a month or so.
Maybe I should go home and rethink my life (as in Star Wars).
