Due to the unexpected service suspension of the Dropbox Linux Client, users of QNAP Systems, Inc. NAS are now unable to activate Dropbox synchronization through the Dropbox Sync app. Users who have the Dropbox Sync app currently installed and are connected to their Dropbox account are unaffected, but if they log out of the app then their service will be suspended.
To continue providing users with convenient cloud sync services, QNAP will soon be releasing a new Cloud Drive Sync - Beta app to support file synchronization between QNAP NAS and Google Drive, Dropbox and more. The new Cloud Drive Sync - Beta app will be available from the QTS App Center for QNAP NAS with QTS 4.1 (or a newer version) installed.
In Q3 2015, QNAP will release a whole new backup solution - Hybrid Backup Restore - that will provide enhanced data protection and restoration by integrating local/remote NAS and cloud backup services as well as by supporting more cloud storage service providers.
QNAP sincerely apologizes for any inconvenience caused by the unexpected service suspension of the Dropbox Sync app. Users with further questions can contact QNAP Technical Support at: http://helpdesk.qnap.com.
