Do I need to back up my certificates?

✍: Guest


Most certificates don't need to be backed up. However, if you encrypt files with Encrypting File System (EFS), you should back up your EFS certificates so you don't lose your data. For more information about how to back up your EFS certificates, see Back up Encrypting File System (EFS) certificate.

Back up Encrypting File System (EFS) certificate

Applies to all editions of Windows Vista.
Which edition of Windows Vista am I using?
If you encrypt data on your computer, you need a way to recover that data in case something happens to the encryption key. If your encryption key is lost or damaged and you don't have a way to recover your data, the data is lost. You will also lose data if you store your encryption key on a smart card and the smart card is damaged or lost. To make sure you can always access your encrypted data, you should back up your encryption certificate and key. If more than one person uses your computer, or if you use a smart card to encrypt files, you should create a file recovery certificate. For more information, see Create a recovery certificate for encrypted files.
