What is Encrypt Backup?

In cryptography, encryption refers to encoding messages or information so that it can not be accessed by hackers and unauthorized party. When it comes to disk/partition/file backup, encrypting an image file with passoword can also help to ensure the safety of the backed up data, so as to protect the privacy of an individual or a group.

For example, if you've encrypted the backups of your company data, then only those who know the password could restore the image file. You don't need to worry about the confidential information being leaked out easily.

However, the built-in backup and restore utility in Windows 10/8/7 doesn't support you to encrypt backups. If you want to add a password to an image file, you may need the help of a powerful backup program, AOMEI Backupper.

How to Encrypt Backup with Password in Windows 10/8/7?

AOMEI Backupper is a complete Windows backup and restore solution providing rich functionality to protect your important data. It enables you to do File Backup, Partition Backup, Disk Backup and System Backup along with many practical options.

In the advanced version AOMEI Backupper Professional, you can find the backup encryption feature in Options and add a password to protect the image file.

Next I'll explain how to create an encrypted backup using Partition Backup as an example.

Step 1. Launch AOMEI Backupper, select Partition Backup under Backup.

System Backup

Step 2. Click Add Partition or Volume to select the source data, then add a destination as you like. You can choose internal/external hard drive, USB, NAS, cloud drive and so on.

Select Destination

Step 3. Manage backup settings before Start Backup. To encrypt the backup with password, just click Options at the bottom, then Enable encryption for backups under General tab. When it's toggled on, you can type the password > confirm the password > click OK.

Encryption

In addition to backup encryption, you can configure many other settings in Options. For example:

Backup mode - The default intelligent backup will only backs up used sectors to save storage space, while sector-by-sector backup will make an exact backup of all sectors.
Compression - The higher the compression level, the smaller the image file, and the longer backup time it will take.
Splitting - Split a large image file into multiple smaller image files in the process of backup.
Comment backup - Write a comment for backup to make it easy to distinguish.

To restore an encrypted image file, you'll be required to enter the password correctly. Note the password is used as a key by the industry-standard AES (Advanced Encryption Standard) cryptographic algorithm, which will totally encrypt all data in the image. So please keep the password in mind or note it down, otherwise the encrypted backup is impossible to recover.

Other features to optimize the backup:

Schedule: If you'd like to modify the source files frequently, and keep the backed up image file up-to-date, you can set up a schedule to execute automatic backup. Schedule includes Daily/Weekly/Monthly/Event triggers/USB plug in. Full backup, incremental and differential backup are optional in Advanced tab.

Scheme: Set up a rule to auto delete old backups in case your storage space is filled up with accumulated image files.

Filter: When you perform File Backup, you could click the funnel icon beside source select box to include or exclude files with specific formats.
