Additional Tips: Export or Back Up Data in Storage Device First

To avoid unnecessary data loss issues in your storage devices such as SD card or USB drive due to file system converting, we highly recommended all users extract or back up important to a secure device or partition in advance.

You may choose to copy files one by one to a new disk or drive. Or if you have quite a big number of data to be transferred, professional backup software shall be your best choice. Here we recommend you try EaseUS Todo Backup which allows you to directly back up target data into compressed image formats within only four steps.

Step 1. For the first time you use EaseUS Todo Backup to back up files, click Create backup on the home screen and then mouse click the big question mark to select backup contents.

Step 5. EaseUS Todo Backup allows users to save the backup files to every device that is handy for you, like a local hard drive, external USB drive, SD card, network drive, or a NAS drive, plus a cloud drive of the EaseUS brand. We personally recommend users to choose the cloud drive prior to a physical drive to save important backups due to the greater accessibility, flexibility and safety.

To be able to access to EaseUS cloud, all you need is an email registration and login.

Step 6. If you're interested in an automatic and intelligent backup schedule for the next file backup task, go on with the "Options" setting. There you can encrypt a confidential file backup, compress the backup image size, or customize a backup scheme to tell the software in what time to start the next backup.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
