On the security panel, you can protect your backup with password:
By default, backups are not protected.
If you want you can select the type of protection and enter the password.
Simple password protection (the second option in the list) is good as it is the zip file standard and the file can be opened with all zip compatible archiving programs if you know the password. For strangers, the files inside the backup are still not accessible without the right password. They can see the file list, but accessing any file inside the file is impossible without knowing the password.
In the professional version, you can use additional "real" file encryption in top of the standard password protection. Please note, that this backup file can only be opened with TK8 Backup Restoring Wizard and the password is required for this.
About the security
If you should lose the password, then standard password protected files can be cracked. For this there are programs available and though it can take months to crack a file, you still have the possibility to access the files if you should forget the password. It has a downside, but the good thing is also that should you really forget your password, your data is not lost forever...
If the backup file is encrypted, there is no possibility to open it without the correct password. TK8 Backup uses one of the strongest Rijandael 256-bit encryption algorithm which is practically impossible to crack within hundreds of years. This is secure, of course, but also dangerous protection method should you lose the password.
The only way to restore Rijandael (AES 256) encrypted backup is to decrypt it at first with included decryption tool.
Login information to access target path
In the Professional version, you can enter here the user name and the password for the destination folder if it is using any authorization. If the network drive is disconnected by Windows, the program can re-connect it automatically using this information.
