Step 1. To clone an HDD to a USB flash drive, make sure that both drives are correctly connected and recognized by Windows. Launch EaseUS Todo Backup and choose "Clone" to begin.

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.
