System Requirements for Carbonite Safe Server Backup (CSSB 6.x)

Your system must meet the following hardware requirements:

• Dual-core CPU
• 2GB of RAM or higher
• 10% or more of disk space on the boot drive for temporary files during installation.
• 10GB or more of disk space on the drive where CSSB is installed for CSSB's own program and configuration files.
  • Additionally, every disk that contains data to be backed up must have space for VSS snapshots. This space is known as shadowstorage. At least 10% of each disk should be dedicated to shadowstorage. CSSB will automatically create and assign shadowstorage to meet this requirement. You can read more about shadowstorage in this Knowledge Base article.

Please note these are the only hardware requirements. Storage configuration (i.e. RAID) does not matter. As long as the above requirements are met, CSSB will function properly.

• Starting with CSSB 6.4, Amazon Corretto 8 is required for full CSSB functionality.
• Backups of Microsoft Exchange Server 2007 have additional requirements/dependencies:
  • Microsoft .NET Framework 4.0 or higher must be installed on the machine where CSSB is installed.
    • The latest version of .NET Framework is available from Microsoft directly: https://www.microsoft.com/net/download
      • 
  • Powershell 2.0 or higher (part of the Windows Management Framework) must also be installed on the machine where CSSB is installed.
• The Check Dependencies option in the Advanced; Tools section can be used to verify whether the proper dependencies are installed on the system.

Your system must also meet these requirements:

• The minimum resolution of your screen should be 1366 x 768.
• The language selected in the CSSB Installer and the CSSB program must match the Windows system locale.
• The Remote Registry Service must be enabled before installation.
• The Volume Shadow Copy Service (VSS) must be enabled. Although the Volume Shadow Service is enabled by default, it may have been turned off after Windows installation.
  • To ensure that VSS is running:
    • Right-click the My Computer (or Computer) icon and choose Manage from the pop up menu.
    • Expand the Services and Applications tree and locate the Volume Shadow Copy Service. If it is not started, change the General Properties to set the Startup Type to Automatic.
• Carbonite Safe Server Backup must be installed and all CSSB operations must be performed as a user that has Administrator privileges.
• Carbonite Safe Server Backup requires access to TCP Ports 10080 and 10081, which are the default ports used by CSSB for backup and restore operations.
  • Alternate ports can be specified by clicking Data Transferring and Networking after navigating to Advanced; Global Settings within the CSSB Enhanced Interface.
• The Carbonite Server Cloud Controller requires access to port 10085. If port 10085 is not available, please refer to Changing the Default Port Used by the ZCBService.
• CSSB depends on the Visual C++ Redistributable. VC++ must be installed and in working order on the system.
  • Errors that reference MSVCP120.dll indicate a damaged or corrupted Microsoft VC++ Redistributable. The systems administrator must repair or reinstall VC++ in order to resolve the errors.
  • CSSB requires Microsoft VC++ Redistributable 2013.
    • VC++ is a common redistributable that can be installed/relied upon/modified/etc by any number of other programs. Any number of versions can be installed simultaneously.
