Questions and Answers
Why can't I sync via USB?
For a long time the USB port in iOS devices wasn’t available to third-party apps. We believe that synchronizing via the local network provides a fast and reliable method even for larger data sets.
Can we put databases on a file server for our team?
No, this is not possible, we’re afraid. DEVONthink does not allow more than one person to access a database at a time.
DEVONthink follows a decentralized data model where each machine has a local copy of the database but syncs to a commonly accessible location. Collaboration via syncing may require special attention, like a shared account on a cloud service, ie. using the same credentials on each machine. Feel free to contact our support team for further information.
With DEVONthink Server, there is also a built-in web server that allows you to broadcast a database on your network. Users can access shared databases through a web browser, even on Windows machines. While it’s not as functional as DEVONthink itself, it can prove useful in an office setting. For more specific information, please refer to the built-in help or manual.
Can I use multiple Dropbox accounts?
No, we’re afraid. The official Dropbox API only pairs with one account at a time.
Can I use OneDrive, Google Drive, …?
Not yet. If you would like to use DEVONthink or DEVONthink To Go with a service that is not yet supported, feel free to let us know. We might add support for it in the future.
Do I have to sync whole databases?
DEVONthink for Mac always uploads complete databases. You can exclude indexed items, though.
DEVONthink To Go always syncs the metadata for whole databases but you can select for the location, the database, or individual groups if you want to sync their content files too. If you sync only the metadata you can download the actual content later on demand.
How safe is my data during a sync?
If you set an encryption key for a sync store all data is AES 256 bit encrypted before leaving the device and is stored in encrypted form on the server. It can only be retrieved using the correct key. The same is true for direct connections where all data is encrypted using the key set in the Bonjour options.
In addition, the username and password you set for newly created databases is used as soon as you sync the database to another device. The database cannot be retrieved from a sync store or via direct connection without entering the right credentials.
I have lost my encryption key. Can you recover it?
Unfortunately no. The encryption key is never shared with us. If we could recover your encryption key anyone else could do this too. We’re using strong encryption to ensure that your privacy (at the time of this writing) can’t be cracked without substantial computing power, if at all. Are you sure that you don’t have noted it down on some piece of paper somewhere?
What is CloudKit and should I switch to it?
iCloud comprises several components. One of them is the file service with iCloud Drive being its user-facing part. Another component is CloudKit, a database service that works behind the curtain and can only be used by applications directly.
DEVONthink’s old iCloud sync was based on the file service which did not let it live up to the maximum possible performance. Contrary to that, the CloudKit sync uses the backend database’s capabilities for a fast, single-pass sync.
