Hyper Backup - Backing Up the NAS Itself

Why the NAS Itself Needs a Backup

Many people think that once files are on the NAS, they are safe forever. The NAS is a great, reliable home for your data. But it is still one box, in one spot, and a lot of things can go wrong with one box.

Your NAS uses RAID, which means it can survive a single drive failing. That is wonderful, and it is why the NAS feels so dependable. But RAID only protects against hardware trouble inside the box. It does nothing about the other ways data disappears.

• Accidental delete. You or a family member erases a folder. RAID faithfully erases it on every drive at once.
• Theft. Someone takes the whole NAS. The redundant drives go with it.
• Fire or flood. A disaster in your home destroys every drive together.
• Ransomware. A nasty program scrambles your files. RAID happily keeps the scrambled version safe.
• The NAS itself failing. The unit, not just a drive, can die - a power surge, a bad board.

The 3-2-1 Rule, in Plain Words

Backup professionals live by a simple little rule called 3-2-1. It sounds technical, but it is just common sense once you say it out loud. It is the target we are aiming for in this guide.

Your NAS is copy number one. A USB drive attached to it, or another Synology, can be copy number two. A cloud backup, or a drive you keep at a relative's house, is your offsite copy number three.

• 3 copies of anything you care about. The original, plus two backups.
• 2 different kinds of storage. For example, your NAS drives and a USB drive - not two copies on the same disk.
• 1 copy kept offsite. Somewhere away from your home, so a fire or theft cannot take everything.

What Hyper Backup Does

Hyper Backup is Synology's free tool for backing up the NAS itself. Think of it as a careful helper that copies your chosen folders to another place, on a schedule, keeping older versions so you can go back in time.

It is different from syncing. A sync makes an exact mirror - if you delete a file, the mirror deletes it too. A backup keeps history, so a mistake on the NAS does not instantly wipe out your safety copy. For protecting the NAS, backup is what you want.

• Copies the shared folders you pick to a separate destination.
• Runs on a schedule, so you do not have to remember.
• Keeps multiple versions, so yesterday's file is still there if today's got messed up.
• Can encrypt the backup, so a stolen drive is useless to a thief.
• Can back up some of your installed apps and settings too.

Where You Can Back Up To

Hyper Backup can send your copy to several kinds of destinations. You do not need all of them. Pick one to start, and you can add another later.

For most homes, I suggest starting with a USB drive for your first backup - it is the easiest and there is no monthly fee. Then add Synology C2 or a second location as your offsite copy to complete the 3-2-1 picture.

Installing Hyper Backup

Hyper Backup is free from Synology, but it may not be installed yet. You add it through Package Center, which is like an app store built into your NAS.

DSM is the name of the Synology system you see in your browser - it stands for DiskStation Manager. This guide is written for DSM version 7. If your screens look a little different, the ideas are the same; just look for the same words.

• Sign in to your NAS in a web browser (DSM, the Synology desktop).
• Open Package Center from the main menu.
• Search for Hyper Backup.
• Click Install and wait for it to finish.
• Open Hyper Backup once it appears in your main menu.

Creating Your First Backup Task

A backup task is just a saved plan: what to copy, where to copy it, and when. Hyper Backup walks you through making one with a friendly wizard. Set aside twenty unhurried minutes.

The very first backup copies everything you chose, so it can take a while - hours, sometimes, depending on how much data you have. That is normal and only happens once. After that, it only copies what changed.

• Open Hyper Backup and start a new backup task (look for the plus sign or Create).
• Choose your destination type - for example, Local folder & USB, or a cloud service.
• If it is a USB drive, plug it in first so it shows up in the list.
• Pick the shared folders you want to include.
• Choose backup settings - schedule, versions, and encryption (covered on the next pages).
• Review the summary and finish. The first backup then begins.

Choosing What to Include

You do not have to back up every last thing. Focus on what would truly hurt to lose. That is usually your personal files, not things you could download again.

Skipping the stuff you could replace keeps your backup smaller, faster, and cheaper - especially if you are paying for cloud space. But if you are unsure, it is fine to back it all up. Better safe than sorry.

• Family photos and videos - these are usually irreplaceable.
• Important documents - taxes, records, scans, letters.
• Anything for a small business - invoices, files, records.
• Your NAS settings and key app data, if offered.

Setting a Schedule

A backup only helps if it runs regularly. The whole point of a schedule is that you never have to remember. Set it once and let the NAS do its job quietly in the background.

Ask yourself: if the NAS died right now, how much recent work could I stand to lose? If the answer is "not much," back up more often. If the files barely change, weekly is plenty.

• Nightly is a great default for a home - say, 2:00 AM when nobody is using things.
• Weekly can be enough if your files rarely change.
• A small business often wants nightly, so at most one day's work is at risk.

Versioning and Rotation

Versioning is one of the most valuable features and worth understanding. It means keeping several older copies, not just the newest one - so you can go back in time to before a mistake.

Imagine you accidentally save over an important document, and the backup runs that night. Without versions, your backup now holds only the ruined file. With versioning, last week's good copy is still there, waiting for you.

• Hyper Backup can keep many versions while using far less space than you would expect, because it only stores what changed between them.
• Rotation means old versions are automatically thinned out over time, so the backup does not grow forever.
• Synology offers a smart rotation setting that keeps more recent versions and fewer old ones - a good, hands-off choice.

Encrypting the Backup

Encryption scrambles your backup so that only someone with the key can read it. If the backup drive is ever lost or stolen, your files stay private. Hyper Backup can turn this on when you create the task.

When you encrypt, Hyper Backup gives you an encryption key or password. This is the single most important thing to keep safe. If you lose it, nobody - not Synology, not me, not anyone - can unlock that backup. It is gone.

• Choose to encrypt the backup when the task is created.
• Save the encryption key file, or write down the password, the moment you get it.
• Store it somewhere separate from the NAS and the backup drive - a safe, a password manager, a locked drawer.
• Keep a second copy of the key in another safe place, just in case.

Checking a Backup Is Good

A backup that quietly went wrong is worse than no backup, because you think you are safe when you are not. Hyper Backup can check its own work, and you should let it.

Checking the status takes a few seconds. Make it a small habit - glance at Hyper Backup every so often, or set up notifications (covered later) so it tells you if something goes wrong.

• In Hyper Backup, each task shows when it last ran and whether it succeeded.
• Hyper Backup has a backup integrity check that confirms the stored data can be read back.
• You can turn on a schedule for that integrity check, so it verifies itself regularly.
• Watch for any task marked with a warning or error, and look into it.

Restoring a Few Files

This is the everyday reason backups earn their keep: you deleted or ruined a file, and you want it back. Hyper Backup lets you reach into a past version and pull out just what you need.

Because of versioning, you can often pick from several dates. If today's file is bad, step back to a day when it was still good. This is the time machine that a plain mirror or RAID simply cannot give you.

• Open Hyper Backup and choose the task that holds your backup.
• Look for the Restore option, then choose to restore data (files and folders).
• Pick which point in time you want - today's version, or an older one.
• Browse to the file or folder you want back.
• Choose where to restore it, and let it copy back.

Restoring the Whole Thing

The big one: your NAS is gone or wiped, and you need to bring everything back. This is the exact disaster a backup exists for, and Hyper Backup is built to handle it.

Synology also offers Hyper Backup Vault, a companion package that sits on the destination NAS to help manage and restore backups between two Synology units. If your backup lives on a second Synology, that is the piece that receives it.

• Same NAS, data lost. You reinstall Hyper Backup, point it at your existing backup, and restore your folders.
• A brand new NAS. You set up the new unit, install Hyper Backup, connect it to your backup destination, and restore.

Synology C2 Cloud, in Brief

Synology C2 is Synology's own cloud service, made to work hand in hand with Hyper Backup. It is one of the easiest ways to get that all-important offsite copy without setting up a second NAS somewhere.

For a home or small business that wants offsite protection without buying and hauling drives around, C2 is a tidy answer. You set it as the destination in Hyper Backup, and it just works.

• It is built by Synology, so it connects to Hyper Backup smoothly.
• Your offsite copy lives in a secure data center, safe from your home's fires and floods.
• You pay a modest fee based on how much space you use.
• Your data can be encrypted, so it stays private in the cloud.

Tips for a USB Backup Drive

A USB drive plugged into the NAS is the simplest, cheapest backup you can make. A few small habits make it far more reliable and useful.

One powerful trick: use two USB drives and swap them. Keep one plugged in and one at a relative's house or in a safe. Every week or two, swap them. Now your USB backup is also an offsite backup - the best of both worlds.

• Buy a drive bigger than your data. Room for versions and future growth saves headaches.
• Label the drive with what it is and the date you started using it.
• Use a good-quality drive from a known brand - this is your safety net, not the place to cut corners.
• Encrypt it (from the earlier chapter) so a lost drive does not become a privacy problem.

Getting a Copy Offsite

The offsite copy is the part people skip, and it is the part that saves you in a real disaster. If a fire or theft takes your home, only the copy that lives elsewhere survives. Here are the friendly ways to get one.

Any of these completes your 3-2-1 plan. You do not need all three. Pick the one that fits your life and budget, and you have covered the disaster that scares people most.

• Cloud backup like Synology C2 - the copy lives in a data center automatically.
• A second Synology at a relative's or your office, backed up over the internet.
• The swap-drive trick - two USB drives, one always kept away from home.

Notifications So You Know It Ran

A backup that fails silently is a trap - you feel safe while you are not. The fix is simple: have the NAS tell you when a backup succeeds, and especially when it fails.

Some people like a note every time it works, for peace of mind. Others only want to hear when something breaks. Either way, the goal is that a failed backup never sits unnoticed for weeks. DSM can also send alerts to the Synology mobile app if you use it.

• In DSM, open Control Panel and find Notification.
• Turn on email notifications and enter an email address you actually check.
• Choose to be notified about backup tasks - success, failure, or both.
• Send yourself a test notification to confirm it arrives.

A Simple Home Backup Plan

Let us tie it all together into a plan you could actually follow. Nothing fancy - just the steps that give a home or small business real protection with little fuss.

Do that, and you have a real 3-2-1 backup. Your data survives a dead drive, a mistake, a theft, and a fire. That is a level of safety most people never reach - and you got there with free software.

• Install Hyper Backup and pick your important shared folders.
• Back up nightly to a USB drive attached to the NAS.
• Turn on versioning so you keep a history of older copies.
• Encrypt the backup and store the key somewhere safe and separate.
• Add an offsite copy - Synology C2, a second NAS, or a swapped USB drive.
• Turn on notifications so a failure never goes unnoticed.
