Best Way to Do Real-Time Backup to External Hard Drive
The best real-time backup software provided in this post to perform real-time backup to external hard drive in Windows 11/10/8/7 to get continuous data protection.
What is real-time backup
Real-time backup is also known as continuous data protection (CDP), or real-time sync. It refers to a type of backup that automatically saving a copy of every change made to the data.
Real-time backup is different from conventional backup. In conventional ways, you can create backup images of the source data at any time point (or based on a schedule), and the accumulated backup files allow you to restore your data to a specified point in time if needed. Any data changes after this point will be erased.
By real-time backup, however, the changes you made to the source directory are reflected in the target directory immediately. This means you can always keep an exact copy of the source files/folders. But at the same time, you won't have multiple restore points to use as archives.
It can be seen that there is no superiority or inferiority between the two. Whether to choose real-time backup depends on your data type and frequency of changes.
Real-time backup to external drive may be necessary in some cases
Data security is the most important thing for most computer users, because data loss may bring great trouble. Therefore, you may take measures like backing up files or folders to protect data.
If you've used Windows Backup and Restore, you probably know that external hard drive is recommended as the backup device. This is due to the fact that it is independent of the Windows operating system as a removable device. This makes the data stored on it immune to system errors.
And if the following conditions are met, a real-time backup to external hard drive may even be better than a regular scheduled backup:
The data you want to back up is very time-sensitive. For example, if you edit a document at work and need to take it home for further use, then you definitely want to keep the latest copy in the external drive.
You need to modify the data fairly frequently. If you modify a file once a day, then a daily scheduled backup may be enough. But if you make changes to it more frequently, without much regularity, then a real-time backup should be more efficient.
Your external drive has limited capacity. High frequency scheduled backups can accumulate a large number of backup files, especially if the data you are backing up is relatively large, your disk will fill up quickly. In this case, real-time backup is a more space-saving choice.
Besides, you can also consider a combination of real-time sync and scheduled backup. This will give you more flexibility in terms of data protection and recovery.
In the following part, I will show you how to create real-time backup to external hard drive.
