QNAP Incorporate Company is one of the storage device manufacture giants, designing and delivering high-quality Network Attached Storage (NAS) and professional Network Video Record (NVR) solutions to users from home to enterprise.

QNAP NAS consists of one or more hard drives that are constantly connected to the internet. It becomes a storage unit that stores all your important files and media such as photos, videos, music and so on. You can consider it as an external hard drive, but rather than being carried around, it’s usually placed at home and enables you to access these files via Internet anytime and anywhere.

Why incremental backup QNAP NAS to NAS?

QNAP NAS is an ideal storage device with large capacity, but the data stored on it is still at risk of loss or damage due to natural or man-made reasons. To give your important files on NAS a double security, it’s better to backup them to a different place, another NAS, for example. Thus you can simply restore these files when one QNAP NAS fails and the data gets lost.

And if you want to back up regularly to keep the data up to date, you can do incremental backup NAS to NAS. Compared with full backup, an incremental backup will only backup new or changed files since the last backup, thereby consumes less storage space and time. And when a full recovery is needed, the restoration process requires the last full backup plus all the incremental backups.

Besides, all the image files in an incremental backup series share a sequential relationship, so the data can be recovered to the state it used to be when any of the incremental backups was done.

How can you do QNAP NAS to NAS incremental backup?

In order to do QNAP NAS to NAS incremental backup successfully, you need a professional backup & restore software that supports QNAP NAS and better be simple in operation.

As far as I searched, you can use Remote Replication of QNAP to achieve this goal. But the setup process is relatively complicated and requires you to have some knowledge of QNAP's QTS operating system. If you are okay with it, here’s a tutorial for creating a NAS to NAS backup.

Hybrid Backup Sync is also an option for QNAP NAS backup, and the downside is the same for me - not simple enough.

If you are as afraid of trouble as I am, or have the needs to manipulate important data between different devices including but not limited to QNAP, I’d like to recommend you another comprehensive and reliable freeware - AOMEI Backupper Standard.

It has complete backup features allowing you to backup QNAP NAS files to external hard drive, USB drive, local disk, etc. in Windows 10/8.1/8.7/XP/Vista. You can easily create a NAS to NAS incremental backup, and schedule it if you want to do the backup at a regular basis.

What’s more, the interface of AOMEI Backupper Standard is so easy that you will know how to operate it once seeing the features’ name. But for your reference, I’ll list the steps anyway.

How to incremental backup QNAP NAS to NAS with AOMEI Backupper?

1. Install and launch AOMEI Backupper Standard.

2. Click Backup tab on the left side of the main interface, and then select File Backup.

3. Hit Add Folder and choose Share/NAS in the popping out window.

4. Click Add Network Location and enter the IP address, username and password of your NAS. With the Anonymous option toggled on, you only need to enter the IP address of your NAS. Then hit OK to add it.

Select Synology Or Qnap Nas User Password

5. Repeat the last step or click Select Network Location in the drop-down menu to choose another NAS as the destination location.

Select A Network Location

6. Click Schedule button on the bottom and go to Advanced tab to choose the way of backup (Incremental Backup by default).

Related tips about using AOMEI Backupper

1. Please note that if anyone of the incremental image files in the sequence is damaged or missing, the subsequent image files will be invalid.

2. Before starting backup, you can click Schedule to set a regular backup task at an exact time daily, weekly, monthly, or just once in General tab.

Schedule Settings

3. There are three ways to perform the scheduled backup, Incremental Backup is the default one, which you don’t have to choose specially. You can also choose Full Backup or Differential Backup in Advance tab of Schedule Settings if needed.

4. The Differential Backup option in Schedule settings is a paid feature of AOMEI Backupper Professional. Compared to incremental backup, differential backup is always directly related to the originating full backup and will back up all data added and changed since the full backup was done. Therefore, it requires more time and space in backup but is more robust in restoring when preceding differential backups are damaged or missing. If you just want to do differential backup once without the urge to make it regularly, you can click the backup task in Home page and choose Backup > Differential Backup manually for free.

5. A full backup must exist as the start point of a series of incremental backups or differential backups. So if you haven’t created any backup task and want to create an incremental backup or a differential backup, a new backup task is required. AOMEI Backupper will run it as a full backup by default at the first time.

6. You can find more auxiliary features in Options, such as data compression, backup image splitting and encryption (available in paid editions).


With its powerful features and intuitive interface, AOMEI Backupper Standard makes it quite easy and quick to do a QNAP NAS incremental backup. And not limited to QNAP, it supports all kinds of storage devices like NAS, HDD, SSD, SSHD, USB drives, Hardware RAID, etc. For instance, it can back up Synology NAS to External Hard Drive, back up Windows 10 to NAS, clone HDD to SSD and so on.
