Install SyncBack without any prompting or messages on the screen (silent install)

This article provides information about installing SyncBack without any prompts or messages on the screen. For more details see the Installing section of the SyncBack help file.

Article Detail

To install SyncBack without any prompts or messages on the screen use the /verysilent command line parameter with the installation executable, e.g.

SyncBackSE_Setup.exe /verysilent

It is important that it is the first command line parameter.

WARNING: When using a silent installation, no prompting can be done. Therefore, if the installer cannot replace a file because it is being used, then it will replace it on reboot. If it needs to reboot to replace the file then it will immediately reboot, without prompting, once the installation is complete.

To prevent the setup from restarting the system, you can add /NORESTART command line parameter. You can also add /CLOSEAPPLICATIONS or /FORCECLOSEAPPLICATIONS parameters to instruct the installer to close applications that are using files that need to be updated by the setup or force close when closing the applications.

You should also bear in mind that if you disable prompting, it is assumed you tacitly agree to those prompts that would normally be displayed (for example, our terms & conditions) and/or that you are aware of the issues that would normally be mentioned. If in doubt, you should manually install a test instance first and satisfy yourself there are no contentious issues.

You can also specify which language the program should use when run (/language), the serial number to use (/SN), the number of days between automatic update checks (/UpdCheckDays - set to 0 to disable update checks, default is 15), and the run counter (/Counter - set to 1 to not be prompted about visiting introduction web page). You can also switch off the prompting about the backup folder when upgrading from V8 to V9 (/NoBackupPrompt). For example, to use French, pass a serial number, switch off update checks, not be prompted about a backup folder for old V7 profiles, and not be prompted about visiting the introduction page when the program is run:

SyncBackSE_Setup.exe /verysilent /language="FR" /SN="XXXXXXXXXX-XXXX-XXXX-XXXX-XXXX-XXXX" /UpdCheckDays="0" /NoBackupPrompt="Y" /Counter="1"

The /UpdCheckDays parameter is only used for new installations. So if SyncBack is already installed then this value is ignored and it will continue to use the existing setting.

/SettingsFolder="folder"This can be used to specify the folder to use to get settings and profiles settings from, e.g. /SettingsFolder="C:\My Folder\"

With SyncBackPro, if you have upgraded from SyncBackSE to SyncBackPro, you may have two serial numbers: the SyncBackSE serial number and the SyncBackPro upgrade serial number. Pass the SyncBackSE serial number with the /SN parameter, and the SyncBackPro upgrade serial number with /SN2, for example:


A full list of command line parameters can be retrieved when you enter the executable command (from the directory where the SyncBack installer is stored):

SyncBackPro_Setup.exe /HELP

Note: Replace the "Pro" section with your product name accordingly if it is different (for example, SyncBackSE_Setup.... etc).

SBM Service and SyncBackPro

For the SyncBackPro installation there are a number of optional installation command line parameters related to the SBM Service (if used):

/SBMS_Hostname="hostname": This is the hostname, IP address, or URL of the SyncBack Management Service (SBM Service). If you are using a HTTP connection type then this is the complete URL include the port number. For example: /SBMS_Hostname="". If you are using a TCP or Named Pipe connection type then this is the hostname or IP address. For example: /SBMS_Hostname="".

/SBMS_Port="port number": This is the port number of the SBM Service. It is only used when the connection type is TCP, and the default port number is 8095. For example: /SBMS_Port="8095"

/SBMS_Username="username": This is the login username for the SBM Service. Typically each user has their own login username for the SBM Service.

/SBMS_Password="password": This is the login password  for the SBM Service.
