@rmschne I think I understand your point, what you suggest will probably work and I will probably even try it live soon.
That said I still believe that easy sync with even slow WebDAVs would have been a way better solution (with the ones slow intentionally as in my case or just because some services/connections are slow today).
FYI, the sync server version of the databases are NOT a backup. Just not.
If it walks like a duck, quaсks like a duck, looks like a duck, but is actually a weird turkey - can you use it as a duck?
Sure, if your laptop disk died, you cannot just copy-paste stuff from WebDAV to local machine and “proper backups” could be more efficient here, yet creating a clean local DB and syncing it with WebDAV sync source would anyway give you all your content with the proper tags, metadata, etc, just as if you have added yet another Mac to sync, wouldn’t it?
When both devices detect each other (both running their respective versions of DEVONthink) via the local network … the sync will just happen.
Sounds like a good workaround, so I’ll probably try it yet certainly UX-wise it’s better if I wouldn’t need to have both devices working at the same time.
Also … on the iPhone … only sync the database that you actually need. No need to do everything and then wait ages for what you call a “slow” backup.
Again a good workaround yet in 99% if not 100% of cases I don’t care about the sync time unless I have to do something special during this time such as making sure both devices are in the same room and apps are running on both. If it takes hours for the first time, so be it if it happens in the background.
