However, if any error occurs, such as an install server or device not being available, or if the backup data read
from the installation media cannot be installed onto the detected hardware without user intervention, an error
message will occur and the

answer any questions normally asked during the install process which are required for a no-prompt installation.
If configured for no-prompt installation, the installation process will proceed automatically as follows:
1. The defined install server and device will be checked to ensure they are available and readable
2. The selected backup will be read and the installation information will be extracted
3. The configuration information from the backup will be compared against the current system configuration to
ensure the storage configuration may be created according to the backup data. If there are non-fatal
problems which can be corrected, they will be corrected automatically.
4. If there are any fatal problems, such as no disks on the new system that match the original system, or if the
disks on the new system are not large enough to contain the original data, the system will enter prompted
mode and the installation menus will appear in order for the user to make changes to correct the problems
before continuing.
Installing from an Encrypted Backup
If the backup to be restored from was encrypted during the backup process, it will be necessary to decrypt the
data during the restore. Unlike restoring data on a live system, where the encryption keys are available on the
backup system, the encryption key must be entered manually during the system installation. The encryption
keys are not stored in the boot media or the backup information as this might be penetrable to hackers.
As warned during the backup process, an encrypted backup cannot be restored
without the proper encryption key. This key may not be retrieved from the backup,
nor can SBAdmin assist in providing the correct key. If you do not have the proper
encryption key needed to decrypt this backup, you will not restore this data!
The encryption key is a value that the user defined prior to performing the backup. If the encryption key is not
known, you will not be able to restore the system from this backup. However, to make encryption keys easier to
remember and/or enter, it may be entered either as a hexadecimal number or an ASCII text equivalent (if this
was the form used to create the original key).
When selecting to install from an encrypted backup, the following message will appear:
Select the appropriate option for entering either a HEX or ASCII encryption key. The third option may be used to
start a shell to type commands at the command line should you need to perform system tasks without reading
the backup data.
