    Step 1 — Back up your devices
    Start by securing your personal documents, photos, and videos. Synology NAS is easy to set up and maintain, and a great place to back up all of your devices.

    Windows & Linux

    Automatic protection for your entire PC

    Protect your Windows and Linux (Beta) PCs with full-device backups of all your files, programs, and settings, on any drive. Flexible restoration lets you recover only files and folders, or replicate the entire device onto a new one.

    Select and protect individual folders

    Don’t need to protect the entire computer? Synchronise folders, and add backup and restoration points to your most important files so you can easily roll back any accidental or malicious modifications.

    masOS

    Automatic folder-level backup 

    Protect important files and folders with automatic real-time or scheduled backups. Versioning enables you to jump back in time to undo a change or to recover from malicious file modifications. 

    External Drives/Memory Cards

    Seamless backups that integrate with your workflow

    Define automatic backup tasks for USB drives or memory cards when connected, and even clear up space when the operation is complete. Flexible retention and two-way file operations are supported to fit even advanced backup workflows.

    Mobile Phones

    Back up photos and videos

    Automatically protect files, then free up space on your phone. Manage your photos and videos in Synology Photos and enable secure sharing with family and friends.
    Step 2 - Back up your NAS to another destination
    Now that you have centralised your data backups, it is important that you add one more layer of protection. While Synology NAS is designed to maintain data integrity and security, natural disasters or theft can still impact you.

    To another Synology NAS

    Comprehensive full-device backups

    Want to keep things simple and efficient? Set up automatic protection of your data, applications, and system settings. Compression and deduplication greatly reduce the amount of storage required.

    For higher-frequency file protection

    For files that are constantly worked on and modified, snapshots and replication tasks can be performed as frequently as every 5 minutes.

    To external devices

    For files and system configurations

    Hyper Backup supports a wide range of backup options and destinations, with versioning, compression, and deduplication for space efficiency.

    For files only

    USB Copy enables fast data export tasks that can be triggered automatically when an external drive is plugged in

    The most comprehensive option

    Hyper Backup supports storing backups on mainstream cloud service providers and Synology C2 Storage. Client-side AES-256 encryption lets you ensure data privacy.
