How to set up the password
The Encryption Settings window is shown in the Compression page of the Backup Properties window or in the New Backup Wizard. The button is available only for full, incremental, differential and mirror with zip backup types (not available for mirror without zip).
By default the No encryption option is selected. If you want to protect your backup, you can choose the type of the encryption to be used. The Zip(2) compatible encryption offers moderate security but is compatible with all third party zip applications.
The best choice is the AES encryption which is the new standard in ZIP protection, (recognized by several third party zip applications like WinZip, 7zip or PKWare). Backup4all supports AES encryption in 3 different key strengths: 128-bit, 192-bit and 256-bit. These numbers reflect the size of the encryption keys used to protect the data - the higher the number the stronger the encryption. All three types provide higher security than the password protection method.
When choosing a password, it is recommended that you use a combination of letters and numbers and at least a 6 character long password.
You should manually enter the password in the New password field and re-enter it in the Confirm new password field to avoid typing errors.
The Old password field is enabled only when the backup job already has a password. You can change the password only if you enter the old one in this field.
This way only the owner of the backup will be allowed to change the password.
The system makes it possible to set different passwords for the same backup job, so the backup may contain zip files with different passwords. Make sure that you remember all passwords that have been used for a backup job, or you will not be able to restore your files.
How to Remove the Password
In the Backup Properties -> Compression page, go to "Encrypt the zip file" section, select the No Encryption option and enter the password that you used in the Old password field. You cannot remove the password if you don't provide the old one.
If you have the Zip(2) compatible encryption or AES encryption option selected, you can also remove the password by entering the Old password and leave the New password and Confirm new password fields empty.
Using Passwords when Restoring
During the restore process of backups with password protection on another computer, the Enter Password dialog will appear. Enter the password and press OK.
If you restore the backup on the same computer where the backup was executed, under the same user account, no password will be required as the password is stored in Windows user account.
If you do not know the password for this backup number you can:
- press Skip backup to go to the next archive - the restore may be incomplete in this case.
- press Stop restore to stop the whole process - the restore will be incomplete, because only a part of the files were restored.
