User Case: How Do I Sync External Hard Drive to Cloud?

“I have a problem while trying to sync my external hard drive to cloud drive. To put it simply, my old computer has a folder, which is used to sync my files to cloud storage. But now, my old computer is broken and I want to sync all my data to cloud using a new computer.

The problem is that Backup and Sync tool on my new computer does not recognize my old hard drive and I could not remember the exact path of synced files. How do I sync files and folders from external hard drive to Google Backup and Sync? Any kindly advices will be appreciated.”

For Google Backup and Sync, it supports two-way synchronization (My Drive and My Computer). My Drive can sync folders between computers while My Computer is created for each PC. If you want to sync external  drive to cloud with different PCs, you can disconnect the external disk or logout the sync tool, go to the web of Google Drive, move the synced folder of old computer to your new computer, then connect the external drive again and click Merge when Backup and Sync ask if you want to merge.

Why Sync External Drive to Cloud?

External hard drives are increasingly used in computers for storage, such as, documents, photos, videos, images, projects, and so on. For example, auto backup files to external hard drive from computer and save backups there. Why do you need to synchronize external drive to Cloud? 

I’m sure the answer is quite clear. There are 3 main reasons that can account for external hard drive file sync:

  • Most cloud device offers users free storage space. For instance, Google Drive offers 15GB free storage, and OneDrive offers 5GB but you can get more by signing up for their 365 account. Among various clouds, MEGA provides 50GB free storage that in the forefront.

  • Save local internal disk space. When you have files stored on Cloud, there is no need to copy them to computer internal disk.

  • keep copies of important files for disaster recovery. As mentioned before, external drive stores crucial data. If you backed up PC to external drive or backup external hard drive to external hard drive, you have important backups here. Since external drive is more vulnerable to peripheral attacks, keeping these backups to one more place adds extra layer of protection.
