All files deleted in a shared folder will be automatically moved into the Recycle Bin.
Effective backup solution
Synology DS216+II can serve as a centralized backup target. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station Backup. Whenever you modify a file, the changes are backed up to DS216+II automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS216+II to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. Synology Hyper Backup allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions.
Increase business productivity with cloud solutions
With comprehensive cloud solutions, DS216+II lets you create your own private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology’s 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key.
Secure your data
DS216+II offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorized system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, DS216+II provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.
