Back in the day, I would keep a group on my DTOP called “On the Go” and put important folders or docs in there I knew I needed to carry with me on my iPad. I’d sync it locally when I needed to. Of course it got slow, and buggy sometimes, and frustrated me so I eventually dumped the whole system and let the app vaporize. Now I’ve finally installed the new DTTG and am trying to get it set up properly. I set it up over dropbox, which worked fine with the inbox and a smaller database, but once I started my main database my dropbox filled up. I don’t have a paid subscription because I only use it for triple backup or move very few docs.
Is it necessary to sync an entire database to access a few documents or folders? Would the smartest thing to be setting up a new “To Go” database instead of a folder on my Mac? I usually try to limit how many databases I have or I worry I’ll get nuttier than I already am with my data. But syncing is otherwise so full featured and smooth compared to before. Way to go!!

Thanks! Our new Sync engine is one of our proudest accomplishments.
Regarding your intial question: You cannot Sync part of a database in DEVONthink To Go 2. You have two options for Syncing an entire database: Contents and metadata or Metadata only.
Metadata only (which we call a “shallow Sync”) is only available with an in-app purchase of the Pro Pack (see DEVONthink To Go 2’s Settings > Manage). You set can Download Files to Always (a full Sync) or On demand (a shallow Sync) for a Sync location, an entire database, or individual groups in a database.
Alternately, yes some people have chosen to create smaller databases, just for Syncing.
Perfect, thanks! I did get the pro pack (and it took me an embarrassingly long time last night to find the meta data option, btw) but it works great now (found the answer in the forums!) I will go ahead and make a smaller database of duplicates for my most important docs. I trust the iOS app enough right now that I foresee such a system working for me indefinitely.
Thanks again!
Glad to hear it! Have a great week!
