By installing the myQNAPcloud Connect, you will be able to connect to the Turbo NAS and easily manage files by drag-and-drop within the Windows Explorer.
Synchronize files anytime, anywhere
Qsync is a useful tool to synchronize files in multiple computers. It creates a specific “Qsync folder” in your devices that you can simply drop files in, and synchronizes the files to all your devices linked to the Turbo NAS.
Sync in multiple ways
Whenever you add, edit, delete or rename a file on one computer, the change applies to all others linked with the Turbo NAS, so you have exactly identical contents on all your devices.
It allows you to remove files on one computer without affecting the copies stored on others that are linked with the Turbo NAS. However, when someone updates the files you deleted from another computer, you can still retrieve them in the Qsync folder.
Advanced Selective Sync
With both Full Sync or Smart Sync options, you can choose to only sync specific sub-folders within the Qsync folder, useful if your computers have limited storage.
Share files and folders easily
Quickly share files with download links
You can create download links to share files with people, even if they don’t have an account on the Turbo NAS. This greatly reduces the time in creating user account and password for users.
Share folders for collaboration
Your life is connected with different groups of people. You can create sub-folders within the Qsync folder, and share each with different groups of Turbo NAS users as a file exchange center. Everyone in the same sub-folder is always kept up-to-date with the latest version of the files.
QNAP NetBak Replicator
Backup data on PC
The QNAP NetBak Replicator, provided with any Turbo NAS unit free of charge, helps you easily back up files from Windows PC - entire disk drives, documents, pictures, music, videos, fonts, emails, and more - to the Turbo NAS. The operation is very simple. You can do the backup task in just a few clicks using NetBak Replicator by the setting of real-time synchronization, scheduled backup and auto-backup from multiple PCs to the Turbo NAS.
NetBak Replicator also supports backing up to a remote server via FTP and WebDAV through the Internet. Imagine that you can backup new photos whenever on vacation. Even you are away from home, the convenient backup supports your memories.
vsphere Client plug-in
Manage QNAP NAS within vSphere Client
The Turbo NAS supports vSphere Client Plug-in that allows managing VMware datastores on the Turbo NAS directly from the vSphere client console. In a large-scale server virtualization environment, management is centralized and straightforward. Administrators can easily control the status of the Turbo NAS and datastores and create additional datastores to multiple ESXi hosts in just a few clicks.
Note: The TS-x51 series doesn’t support vSphere Client plug-in.
