Overview

Every time when you re-installing or upgrading Windows 10, the operating system will create a Windows.old folder which holds a copy of your previous Windows installation, including user profiles, installed program & settings and personal files. If something goes wrong during or after the installation, you can restore windows.old to easily and quickly go back to previous Windows version without reinstalling system & installed programs and losing data. So, it is important for you to protect windows.old folder from unexpected data loss disaster. The best way to do this job is to move or copy windows.old to an external hard drive. Here we will show you how to do it in simple steps.  

Why You Need to Backup or Move windows.Old to External Drive

Even windows.old folder is important, but it is not existing on your computer all the time. In some special situations, it might be deleted. First, Microsoft only keeps windows.old folder on your computer for 30 days since your last Windows installation. Now it is minimized to 10 days since you installed the Windows 10 Anniversary update. After the time, windows.old folder will be deleted automatically. And second, as a complete backup of your whole system partition, Windows.old will take much of your disk space and cause low disk space. In this case, you might delete it when you are trying Windows 10 disk cleanup or other tools to free up disk space by deleting system files. 

When you lose windows.old folder in these special cases, you won't be able to go back to the previous system without losing data. So we recommended you move or copy windows.old to another drive (here external drive is a better choice). It is the best way to keep and backup windows.old folder for a long time.

What is the difference between Clone and Backup? In what cases should I use Clone?

Clone will copy one disk to another or one partition to another (unallocated space is also supported). Usually, this option is used to upgrade the current disk by creating an identical copy. Backup will generate a .PBD image file containing the selected files or system that can be restored from the .PBD image if needed.

What is the difference between System Backup and Disk Backup?

System Backup will auto-select the system boot related partition(s) as the backup source to make sure the system image can be restored properly. Disk/Partition Backup will allow you to manually select a whole disk or speficy a certain partition as the backup source. You will get the same backup result as System Backup if you manually select the system and boot partitions with the Disk/Partition Backup option.

As a computer newbie, what features should I use to protect my computer?

You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.

What kind of storage service should I use to save my backup images?

EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD. It is suggested to save the images to the internal/external/network drives to save time as those kinds of disks have a better read-write speed. It is suggested NOT to save the image on the source disk, because once the disk is damaged, all the files on the disk will become unavailable and you will be unable to restore the image.

As a company network administrator, what features should I use to protect our internal computers?

It is recommended that you use the SQL Backup feature to back up your company's SQL server and Exchange Backup feature to back up the Exchange server. In addition, you can execute System Backup to back up the system and boot partitions on every computer and set a plan to execute the backup once a day or twice a week to ensure that the computer can be restored timely when it has boot issues. File Backup feature can be used to back up important user data. If there are a large quantity of computers, you can purchase EaseUS Backup Center to manage the backups on the client computers centrally.
