Quick Start

The Quick Start guide includes instructions on how to install and configure your first backup with ZCB. Please click Help > Getting Started within ZCB, or locate the Quick Start guide at 


ZCB installation involves two steps: install the software and import the cloud certificate. Product downloads and the cloud certificate are available on the Zmanda Network Downloads screen.

If the product downloads and/or the cloud certificate are not available for download, please see Purchase & Payment Verification Errors.


ZCB uses the InstallShield installer and self-extracting .exe files for installation. After the installer is downloaded, double-click the file to begin installation. 

The amandabackup user

A new user named amandabackup is created during installation. ZCB uses amandabackup for all backup-related tasks.

For more information about amandabackup, please see What is the amandabackup user?

Import the cloud certificate

ZCB uses a cloud certificate to verify subscription status. A valid subscription is required in order to perform backups.

The cloud certificate must be downloaded from the Zmanda Network Downloads screen. Once downloaded, import the certificate into ZCB using the Cloud > Import Cloud Certificate menu option.

Command-line installation

ZCB can be installed via command line. Please see Command-line installation and configuration of ZCB.


The following terms are used throughout this document.

Backup Types

Zmanda Cloud Backup supports the backup of many types of data, such as File System, System State, Microsoft SQL Server, and more. These are referred to as backup types

Please refer to the Supported Backup Types section for details.

Backup Sets

What to back up, when to back it up, how long to keep it, and other such configuration parameters are collectively referred to as a backup set. Each backup set has its own unique name, chosen by the user, and may only contain one backup type. 

For example, you cannot back up an Exchange database and Windows System state in the same backup set. Instead, you must create a new backup set for each type of backup.

Working with Backup Sets

Backup sets are listed along the left edge of the ZCB display. While on the Backup tab, you can create, edit, activate, deactivate, validate, delete, or clone backup sets. You can also trigger a backup to take place immediately with the Backup Now option.

All of these options are shown in a toolbar at the top of each backup set. The same operations are also available in the File menu or by right-clicking the backup set icon on the left side of the program. 

Backup Now: Use this option to begin a backup immediately, in addition to any regularly scheduled backups. 

Enable/Disable a backup set: An Enabled backup set will perform scheduled backups and be eligible for a restore operation. A Disabled backup set will not perform scheduled backups, but will be eligible for a restore. Disabled backup sets cannot use Backup Now. A Disabled backup set that is Enabled will begin backing up according to its schedules. By default a backup set is in the Enabled state.

A backup set must be saved after it is Enabled or Disabled in order for the change to take effect. 

Validate a backup set: This is a simple way to check whether the essential configuration for the backup set is correct or not. A failed validation indicates that a backup cannot be performed, and an error is returned to the user. Backup set configurations are automatically validated when the backup set is saved and before any backup run is performed. 

Delete a backup set: When the Delete Backup Set operation is chosen, ZCB will present the user with the following two options. 

Delete this backup set configuration and all associated backup data from cloud and disk.

    • Selecting this operation will remove the backup set from ZCB. All data associated with the backup set, on both the local disk and on the cloud, will be deleted. 
    • Deletion of data, especially from the cloud, can take a long time. Please be patient. 
    • A popup will appear to confirm the choice.

Just delete the configuration for this backup set from this computer, but retain the associated backup data.

    • Selecting this operation will remove the backup set from ZCB, but all data will be left intact on both local disk and the cloud.
    • A popup will appear to confirm the choice.
    • The backup set can be recovered by running a Restore Catalog operation.

Backup data that is deleted cannot be recovered.

Copy a backup set: This option will create an exact copy of the current backup set. Schedules can be carried over to the cloned backup set, or not, at the user's discretion.

The copied backup set can then be modified as necessary. Users who wish to create multiple, similar backup sets can use the clone feature to reduce setup time.

Backup Levels

Full backups, Differential backups, and Incremental backups are the three backup levels. Not all backup types will support all three backup levels. 

Full backup: This type of backup will back up all of the data associated with the backup set.

Differential backup: This type of backup will back up only the data which changed since the last successful full backup.

Incremental backup: This type of backup will back up only the data which changed since the last successful full, differential, or incremental backup.

For more information, please see What are Incremental and Differential backups?

Backup Runs

Each time a backup is performed, whether by schedule or manually, it creates a unique entry on the Report page. Each such entry is a backup run. A backup run will list details such as start time, end time, and backup size, and if successful will have an associated archive of backup data.

In most cases, backup runs can be restored, managed, and deleted independently of other backup runs. 

Other operations can also have runs. Restore runs, upload runs, and download runs are also possible.
