Summary: In this article, you will learn how to back up your Mac with Time Machine without an external hard drive. You will be able to save your Mac backups to a shared folder or disk easily by following this step-by-step guide. Meanwhile, iBoysoft DiskGeeker brings you an even easier way to back up your Mac and your data - disk clone.
For most Mac users, Time Machine on Mac is definitely the most convenient and simplest backup solution for automatically backing up the macOS system and your personal data, including apps, photos, files, and more. You can use an external hard drive, Airport Time Capsule, or a network drive for Time Machine backups.
This article will help you look at how to create a Time Machine backup to NAS with a stepwise guide. By following the steps carefully, you will be able to save the Time Machine backups to an online shared folder for restoring your Mac and data at some point.
Can you back up Mac to NAS
Absolutely, you can. Apple states that you can use Time Machine with an Airport Time Capsule by Apple, with a network-attached storage (NAS), or with an external storage device connected directly to your Mac through a USB or Thunderbolt port.
But not all network-attacked storage can store Time Machine backups. It requires your network server or NAS device to support Server Message Block (SMB) or Apple Filing Protocol (AFP).
In addition, some network disks made by non-Apple vendors do not support Time Machine. It is advised to contact your disk maker to see if it can be used for Time Machine backups.
How to back up your Mac to a NAS with Time Machine
Currently, Synology NAS is the most favored NAS provider, so this article will primarily talk about how to back up to a Synology NAS with Time Machine. The process probably will be similar for other NAS devices by other manufacturers and can be broken up into two main steps:
1. Configure the NAS for Time Machine backups
2. Set up the Time Machine on Mac to use the NAS
Note: this tutorial assumes that you have finished the initial Synology NAS setup, including the installation of the DSM on your Mac and the establishment of a storage pool.
Step 1: Configure the NAS settings for Time Machine backup
1. Go to Control Panel after signing in to DSM with an administrator account.
2. Select Shared Folder and click Create at the toolbar.
3. In the Shared Folder Creation Wizard,
- Name: input a recognizable name like "Time Machine", "Time Machine Folder", or "Time Machine Backup".
- Description: write any description you would like to help you recognize the folder
- Location: Select a storage volume/pool
4. Click Next. It is NOT recommended to enable the Recycle Bin feature and use the encryption on the shared folder on the Synology NAS.
5. Continue to click Next or configure the settings in the following wizards including Advanced, Permissions, Advanced Permissions, and NFS Permissions until you arrive at the Confirm settings page.
6. Click Apply to complete creating a shared folder for Time Machine backup to NAS.
7. Stay in the Control Panel window and select File Services.
8. Go to the SMB tab and tick Enable SMB Service. For macOS Sierra (10.12) and later, Time Machine uses SMB as the default protocol.
9. Go to Advanced, and then Enable Bonjour Time Machine broadcast via SMB. In this way, if your network server or NAS device supports Time Machine Bonjour notifications, you can set up Time Machine backups even if you are not connected to the server.
10. Click on Set Time Machine Folders.
11. Check the folder where you want the Time Machine application to back up your Mac on your Synology NAS.
12. Click Save to save your settings and then you are done with setting the shared folder as Time Machine's backup target.
Step 2: Set up Time Machine backup to your NAS
1. Open System Preferences from the Apple Menu and click Time Machine.
2. For easier access, tick the box Show Time Machine in Menu Bar; Select Back Up Automatically to let Time Machine is constantly backing up your Mac.
3. Click Select Backup Disk.
4. Choose the shared folder you created on the Synology NAS. For example, Time Machine on sever name of your Synology NAS.local. If you would like to encrypt your Time Machine backup to NAS, check Encrypt backups. This will slow down your backup when you are first time backing up your Mac to NAS.
5. Click Use Disk.
6. Click Connect and then provide your username and password for the shared folder on DSM.
7. Click Connect and Time Machine will start backing up your system and your data shortly.
Step 3: Restore files with Time Machine backup to NAS (optional)
If you inadvertently deleted some files on your Mac and happened to empty the Trash can, you can use the Time Machine backup to NAS to restore your lost files easily.
Just like restoring files from backups on an external hard drive, you just need to connect to the NAS, open Time Machine software, and use the slider on the right side of your screen to navigate through your backed-up files. Then select the file or folder you want to get back and click Restore to restore it to the original location.
