Synology Hyper Backup: What It Does & How to Use It

Synology Hyper Backup is a built-in backup tool for Synology NAS devices that lets you back up your data to multiple destinations, including external drives, another NAS, or cloud services. You choose what to back up, where to send it, and how often, and Hyper Backup handles versioning, deduplication, and integrity checks automatically. This article explains how it works, how to set it up, common issues, and how it compares to other backup options.

What Is Hyper Backup?

Hyper Backup is a free application included in Synology’s DiskStation Manager (DSM) operating system. It was introduced to replace the older “Data Backup” and “Cloud Backup” packages, consolidating them into one tool. It supports backing up shared folders, system configuration, and even specific applications like MailPlus or Docker (via the Hyper Backup Vault on the destination). The key feature is its versioning system: every backup run creates a new version of your data, but Hyper Backup uses block-level deduplication so only changed blocks are stored, saving significant space.

Hyper Backup is different from Synology Snapshot Replication, which is a separate package for near-instant snapshots of shared folders. Snapshots are not a backup—they live on the same NAS and protect against accidental deletion or ransomware, but not against hardware failure or theft. Hyper Backup copies data off-site or to another device, so it is a true backup.

How Hyper Backup Works

Hyper Backup works by creating a backup task that runs on a schedule. When a task runs, it scans the selected source folders and compares them to the last backup. Only new or changed blocks are transferred, and a new version is created. You can set retention policies to keep a certain number of versions or keep versions for a certain period (e.g., keep 30 daily versions, 12 weekly, 3 monthly).

The backup destination can be one of several types:

• Local shared folder — on the same NAS or an external USB drive attached to it.
• Remote NAS (rsync) — another Synology NAS or any rsync-compatible server.
• Cloud services — including S3-compatible storage, Azure Blob, Google Drive, Dropbox, and others.
• Hyper Backup Vault — a package you install on another Synology NAS to receive backups.

Hyper Backup also supports client-side encryption: you can set a password to encrypt your backup data before it leaves your NAS, so the destination (even a cloud provider) cannot read your files. This is highly recommended for cloud backups.

Setting Up a Backup Task

To create your first backup task, open Hyper Backup from the DSM main menu and click “Create” in the top-left corner. The wizard will guide you through the following steps:

1. Choose the backup destination type (local, remote, or cloud).
2. Enter the connection details (e.g., for a remote NAS, the IP address, username, and password; for cloud, the API key or OAuth).
3. Select the data to back up — you can pick shared folders and system configuration. You can also exclude specific subfolders or file types.
4. Set the backup schedule (e.g., daily at 2 AM) and choose whether to enable integrity checks and email notifications.
5. Choose the retention policy — how many versions to keep and for how long.
6. If you want encryption, set a password and optionally a recovery key (a file you must keep safe).

After the task is created, you can run it manually by clicking “Back up now.” The first backup will be a full backup, so it may take a long time depending on your data size and network speed. Subsequent backups will be incremental.

Common Problems and How to Fix Them

Users often encounter a few recurring issues with Hyper Backup. Here are the most common ones and their typical fixes:

• Backup fails with “connection timeout” — This usually happens with cloud destinations when the network is slow or the NAS is behind a firewall. Check your firewall settings, try increasing the timeout in the task’s settings, or use a different network.
• Backup is very slow — If you are backing up to a cloud service, your upload speed is the bottleneck. For local or remote backups, check if the destination disk is healthy and if the network link is gigabit or faster. Also, ensure you have enabled deduplication (it is on by default).
• Cannot restore a file — If you need to restore a file, go to Hyper Backup, select the task, and click “Restore.” You can choose a specific version and browse its contents. If the file is missing, check if it was excluded from the backup.
• Hyper Backup Vault says “not enough space” — The destination NAS must have free space equal to at least the size of the source data (plus room for versions). Delete old versions or expand the storage.
• Encryption password lost — There is no way to recover the password. If you lose it, the backup is unusable. Always store the recovery key file in a safe place.

Hyper Backup vs. Other Backup Options

To decide if Hyper Backup is right for you, compare it to other common backup methods:

• USB Copy — A simple tool for copying files to an external drive, but it does not do versioning or deduplication. Hyper Backup is more robust.
• Cloud Sync — This syncs files to a cloud folder, but it is not a versioned backup. If you delete a file, it is deleted in the cloud too. Hyper Backup keeps versions.
• Snapshot Replication — As mentioned, snapshots are not a backup. Use Hyper Backup for off-site protection.
• Third-party tools (like Duplicati or Rclone) — These can also back up to cloud, but they require more setup and may not have the same integration with DSM. Hyper Backup is built-in and has a user-friendly interface.

For most home and small business users, Hyper Backup is the best choice because it is free, supports multiple destinations, and has a straightforward restore process.

Costs and Storage Considerations

Hyper Backup itself is free. The costs come from the storage you use. If you back up to an external drive, you only pay for the drive. If you use a cloud service, you pay for the storage space and possibly egress fees when restoring. Popular options include Amazon S3 (pricing per GB), Backblaze B2 (cheaper, with no egress fees for the first 3x the storage), and Google Drive (flat subscription).

To estimate how much space you need, remember that Hyper Backup stores multiple versions. With deduplication, the space used is roughly the size of the current data plus the sum of all changes between versions. For example, if you have 1 TB of data and you change 1% per day, after 30 days you might have about 1.3 TB of backup space used. You can set a retention policy to limit this.

Also note that Hyper Backup supports “smart recycle” for versions: it can keep all versions for a short period, then weekly or monthly versions for longer periods, which helps control space usage.

Safety and Best Practices

Backups are only useful if they work when you need them. Follow these best practices:

• Test restores regularly — At least once a quarter, do a test restore of a few files to a different location to verify the backup is not corrupted.
• Use encryption for cloud backups — This protects your data if the cloud provider is compromised.
• Enable integrity checks — Hyper Backup can periodically verify the backup data against the source. This catches bit rot and other errors.
• Keep a copy off-site — If your NAS is stolen or destroyed, a local backup on an external drive won’t help. Use at least one cloud or remote NAS destination.
• Monitor backup logs — Enable email notifications so you know when a backup fails. A failed backup for weeks is a silent disaster.

Frequently Asked Questions

Can Hyper Backup back up to an external USB drive?

Yes. When creating a task, choose “Local shared folder” and then select the external drive’s shared folder (e.g., /volumeUSB1/usbshare). Note that the drive must be formatted with a filesystem supported by DSM (ext4, Btrfs, NTFS, etc.).

Can I restore a single file from an old version?

Yes. Go to Hyper Backup, select the task, click “Restore,” choose the version you want, and browse to the file. You can restore it to its original location or a different one.

Does Hyper Backup back up Docker containers?

Hyper Backup can back up Docker volumes if they are stored in shared folders. It does not back up the container configuration directly, but you can use the “Container Manager” export feature for that. Alternatively, use the Hyper Backup Vault package on the destination to get more application-specific backup support.

What is the difference between Hyper Backup and Snapshot Replication?

Snapshot Replication creates point-in-time snapshots of shared folders on the same NAS. It is instant and uses little space, but does not protect against hardware failure. Hyper Backup copies data to another location, which is a true backup. Use both for comprehensive protection.

Can I back up to a non-Synology rsync server?

Yes. Hyper Backup supports rsync protocol, so you can back up to any rsync-compatible server (e.g., a Linux machine with rsyncd). Choose “Remote rsync” as the destination type and enter the server details.

How do I change the retention policy after creating a task?

Go to Hyper Backup, select the task, click “Settings,” and then the “Versioning” tab. There you can adjust how many versions to keep and for how long. Changes apply to future backups, not to existing versions.
