A brief introduction to Google Drive
Google Drive is an immensely popular cloud storage service that lets you save various files to the cloud. It offers multiple apps to help you across your files on various devices including smartphones, tablets, or computers. What’s more, Google Drive's popularity is built on useful collaborative tools and built-in integrations with Google's suite of products and services.

Why sync folders to Google Drive?
First of all, backing up files to a cloud can prevent your data from losing in hardware failure, system crash, natural disaster, and so on. As one of the biggest cloud storage, Google Drive's free tier of Google Drive comes with 15 GB of storage. This means that if you have a Google account, you already have 15 GB of free storage on Google Drive. So, it is a good idea to backup files to Google Drive.
Generally, there must be some folders on your PC that contain many vital files and you want to sync to Google Drive directly and constantly. Storing these folders in Google Drive can protect your folders and help you access these folders on other devices like smartphone or tablet easily. Or, when you don’t have enough disk space as backup storage on the local hard drive, it is a good idea to sync the local folder to the cloud to save the disk storage.
How do I sync multiple folders to Google Drive?
Many users may wonder how to sync multiple folders to Google Drive with ease. Actually, it is not hard. Here, we will introduce an effective way to achieve that, you can read on to learn the detailed steps.
Part 1. Sync multiple folders to Google Drive on one computer
The web app of Google Drive allows you to upload files or folders manually only. So, to sync desktop folders to Google Drive, you should rely on the official desktop app of Google Drive. With it, you can easily sync single or multiple folders from local to the cloud automatically and constantly.
Please follow the step-by-step guide below to sync PC folders to Google Drive with Drive for desktop (the original Backup and Sync):
1. Download the Drive for desktop software and start the installation. Then, log in to your Google account according to the prompts.

2. Next, click Add folder on the My computer screen, and you could specify which folder(s) you would like to sync to Google Drive.

✎Note: You can also click the Change link to back up only photos and videos or add file extensions that you do not want to sync.
3. In the next step, click Back up to Google Photos and tap Done.

4. You can set the file upload size in the program's Settings: Storage Saver or Original quality. Finally, click Save to add the folder to Google Photos.

✎Note: As we all know, Google Drive for desktop (the original Backup & Sync) is the desktop app for Google Drive and Google Photos. You can also use it to upload folders to Google Photos.
Part 2. Sync multiple folders to Google Drive from different computers
If the folders you want to sync to Google Drive are on different computers, you can also turn to Drive for desktop for help. Generally, one way to sync multiple folders to Google Drive from different computers is to use a single Google account across different computers. That approach will put all your PC folders in one Google Drive account and keep them synced across your different computers with Google Drive for desktop.
What but is worth reminding, if you sync multiple folders to Google Drive simultaneously, you need much storage space that is large enough to hold that much data. The free 15 GB of Google account is usually far too small to hold data from multiple desktops.
If you need more backup space, you can upgrade your Google Drive account. However, the advanced plans of Google Drive are not very reasonable because 100 GB or 200 GB may be insufficient, but 2TB is too much. Therefore, if you only use Google Drive for PC backup, you can turn to another PC cloud backup service with more professional backup technology and a more reasonable price.
Part 3. Sync multiple folders to Google Drive frequently
With the Google Drive desktop app, you can sync files between local hard drive and cloud easily. If you want to sync files from local to the cloud frequently, you can rely on a third-party tool like AOMEI Backupper Standard, a professional backup and sync software for Windows PC.
