Release Level OS/Architecture Operating System Requirements Hardware Requirements Image Name and PA Part Number New Features
8.2.2.0 Windows x64

Operating system support on Windows x64:

  • Windows Server 2016 Standard or Datacenter editions (Server Core and Desktop Experience modes)
  • Windows Server 2019 Standard or Datacenter editions (Server Core and Desktop Experience modes)
  • Windows Server 2022 Standard or Datacenter editions (Server Core and Desktop Experience modes)
  • Windows Server 2025 Standard or Datacenter editions (Server Core and Desktop Experience modes)

Operating system support on Windows x64 but only with the Remote Management capabilities of the MMC GUI interface:

  • Windows 8.1 (Professional or Enterprise editions)
  • Windows 10 (Professional or Enterprise editions)
  • Windows 11 (Professional or Enterprise editions)

Application Requirements:

  • Microsoft Exchange Server 2013 CU2 and later CU
  • Microsoft Exchange Server 2016
  • Microsoft Exchange Server 2019
  • Microsoft Exchange Server Subscription Edition (SE)

System:

  • Compatible x64 hardware supported by the operating system and the Microsoft Exchange Server

Multiple Domain Controller Environments:

Disk space:

  • A minimum of 208 MB of disk space for the product to be installed.
  • At least 2.1 GB disk space for Microsoft prerequisites, which is installed automatically if they are not already installed on the system when you start the Data Protection for Microsoft Exchange Server or IBM Storage Protect Snapshot for Microsoft Exchange Server component installation.

Additional Notes:

  • Note: Some of the prerequisites defined in this document might require a system restart. To avoid a system restart, ensure that all of the minimum software requirement prerequisites detailed in the "Microsoft prerequisites" section of this document are installed before you start the IBM Storage Protect Snapshot for Microsoft Exchange Server or Data Protection for Microsoft Exchange Server installation process.

Metadata space requirements (IBM Storage Protect Snapshot for Microsoft Exchange Server only):

  • In addition to the space that is required for the global product installation, IBM Storage Protect Snapshot uses disk space to hold vital product data that is used to track and manage snapshots. By default, the metadata is stored in the 'vss_staging' subdirectory of the IBM Storage Protect Snapshot VSS Requestor component's installation directory.
  • Note: The IBM Storage Protect Snapshot VSS Requestor component is also known as the IBM Storage Protect™ Backup-Archive Client.
  • The amount of space required is directly proportional to the number of snapshots that you maintain on the system. Ensure that there is at least 1 megabyte of available free disk space to hold the metadata for each snapshot that you plan to keep on the system.
  • In addition, if you are protecting a Microsoft Exchange Server, IBM Storage Protect Snapshot keeps mailbox history information in the metadata to support individual mailbox restore (IMR) processing. The amount of space required for this protection is directly proportional to the number of mailboxes in the entire organization. Ensure that for each user mailbox in your organization, at least 50 KB of disk space are free to hold the metadata.
  • Therefore, it is recommended that you have at least 200 MB available for the described metadata - though the need for more is possible depending on your operating environment.
