Continuous Backup is a feature providing backup for selective data whenever change is made. Depending on the option selected, every version of a file is backed up close to real time.
Continuous Backup feature is only supported on Windows platform.
After the Continuous Backup feature is enabled, you are required to perform a FULL BACKUP of the backup set. This is to ensure all files from the backup source are uploaded to the backup destination(s), as Continuous backup will only backup updated files after a full backup is performed.
Retention policy defines the policies of persistent data management for meeting business data archival requirements.
When a backup job is performed, for data that are modified or deleted on the client computer, their existing version on the backup destination (backed up previously) would be moved into retention area, while newly backed up file would be placed in the current data area.
Specifically, retention policy setting defines how long are these data kept within the retention area before they are deleted permanently from the backup destination.
For backed up data that have not been updated or deleted from the client computer, they are kept in the data area on the backup destination and remain untouched.
The retention policy can be defined where retained file (in the retention area) are removed automatically after a user specific number of days or backup jobs.
The temporary directory is used for various purposes, such as storage of temporary spooled file (for database specific backup type in Cloudbacko Pro), remote file list, local file list, temporary delta file and other files of temporary nature.
In %edition_name% for Windows system image and Lotus Notes, it is highly recommended that the temporary directory or volume used for these modules is not a system volume (e.g. not the same partition which the operating system is installed on). And sufficient disk space must be allocated for the temporary directory, and the formula of calculation of disk space is as following:
(Total File Size * Delta Ratio) * number of backup destinations = Maximum Free Space Required
Administrators need to pay attention to the maximum file size limitation of different file system format, so that database file can be spooled to the temporary directory.
It is strongly suggested to use local drive instead of network drive to ensure optimal backup/restore performance.
Enable Volume Shadow Copy defines whether to enable Microsoft Volume Shadow Copy Service (VSS) for the backup set.
Volume Shadow Copy | Action |
Enabled | Create a snapshot of the data to be backed up for exclusively opened file. |
Disabled | Do not create a snapshot of the data to be backed up for exclusively opened file. Error message will be shown for files that are opened during the backup process. |
Enabling the Volume Shadow Copy option will allow backup of local files that are exclusively opened during the backup process (e.g. Outlook PST file).

OpenDirect restore makes use of the granular restore technology to make file-level restore possible, even from an image file or zipped file. It is particularly useful if you only need to restore individual file(s) from a large-sized image or file which would normally take much longer time to perform a complete restore before you can access any of the data. OpenDirect restore gives you a fast and pin-point file-level restore solution.
OpenDirect feature can only be enabled during backup set creation process. Once OpenDirect Restore feature is enabled and the backup set is saved, it is NOT possible to disable it afterwards, and vice versa. A new backup set will have to be created again if you wish to make changes the OpenDirect setting.
OpenDirect feature can only be supported by CloudBacko Pro and CloudBacko Lite.
The encryption section shows you the current encryption settings.
Encryption settings are set at a backup set's creation time, even if the password is changed afterwards, the encryption key remains the same and cannot be modified afterwards.
Encryption settings are set at a backup set's creation time and cannot be modified afterwards.
For CloudBacko Pro and Lite users, it is very important to export current configuration settings using our tools in Utilities > Export/Import Settings, the file settings.sys will be exported. Please keep the settings.sys in a safe places.
If your current backup computer is crashed and the settings.sys file is lost, you will not be able to restore the current settings including the encryption key, and the data that you backup is irretrievable.
For CloudBacko Home users, your hashed encryption key will be kept on our server. You don't have to worry on export your configuration.
Encryption Key | The hashed key will not be shown. Click on the "Unmask encrypting key" to show the hashed encryption key. |
Algorithm | One of the following 3 backup algorithms will be shown.
|
Method | One of the following backup method will be shown.
|
Key length | One of the following key length will be shown.

Once an encryption key has been defined for a backup set and the settings are saved, it cannot be changed. If you need to change the encryption key, then a new backup set will need to be created and the data backed up from scratch.
