Download Zmanda Cloud Backup User Guide

Unless your backup data is to be sent to some external party (which may want to verify the authenticity
of data), self-signed certificates can be safely used for encryption with ZCB. You can generate your own
self-signed certificate for free by downloading simple-to-use tools such as abylon selfcert. Openssl utility
also can be used for this purpose.
If you already have a personal certificate but it is not in PFX format
If you have an installed non-PFX certificate, you can export it to a PFX file. Please note that you need to
have access to its private key.
To do this, from the Windows Start menu, click Run and enter certmgr.msc. Now, find the certificate to
export, double-click it, and then click Details. Choose the Copy To File option, which will let you select a
location for the exported certificate. When exporting the certificate, make sure that:

The Yes, export the private key option is checked (This option will appear only if the private key
is marked as exportable and you have access to the private key.)

the Delete Private Key if export is successful option is left unchecked
After the file has been saved, close the certmgr.msc utility. The exported certificate should be in a folder
that is accessible by the amandabackup user.
Importing the PFX certificate
To use encryption with ZCB, you need to import your PFX certificate into Windows certificate store using
the procedure described in Importing the PFX certificate into certificate store for a user section below.
You need to complete this procedure for the following Windows users:



amandabackup
Administrator
The Windows user who has launched the ZCB user interface (if manual backups are going to be
performed), say “johndoe”.
Importing the PFX certificate into certificate store for a Windows user
1. Log on to the ZCB machine as the desired Windows user.
2. Double click on the PFX certificate file to start the Certificate Import Wizard. The password
used to protect the private key must be entered. For encryption with ZCB:
a. Do NOT select the option - Enable Strong private key protection. You will be prompted
every time the private key is used by an application if you enable this option.
b. Select the Mark this key as exportable option.
3. Choose all the default options and complete the import.
Performing Backups
Once you have saved the backup set, you can perform backups. You can either launch a manual backup
or add schedules to backup automatically at a specific time.
