How Backup and Restore Operations Function on 64-bit Windows Platforms

Due to architectural differences between 64-bit and 32-bit Windows platforms, various elements of 64-bit operating systems cannot be accessed by 32-bit applications. These elements include areas of the Windows System Registry, system settings files included in a System State backup, and Volume Shadow Copy Service writers.

To overcome these limitations, and to successfully perform backup and restore operations when the Arcserve Backup server is running a 64-bit version of Windows, you must install the 64-bit version of the Arcserve Backup Client Agent on the Arcserve Backup server.

This configuration lets the 64-bit Client Agent run as a native process on the local Arcserve Backup server, which manifests the capability to perform browse, backup and restore operations on the local file system, System State, System Registry, and Volume Shadow Copy Service writers in the same manner as remote browse, backup, and restore operations using the 32-bit Client Agent for Windows.

For more information about Arcserve Backup Agents and Options supported by 64-bit Windows platforms, see the readme file.
