Item #34 - Problems under Windows XP [Closed - Unresolved]

We have attempted to run VSS under multiple Windows XP based computers. It works well with Windows 7 and Server 2003/2008. Areca-Backup version 7.4, ArecaVSS version 2.3, Java Version 1.7.0_25, Windows XP Pro SP3. We verified the VSS service is running and specifically ran Areca under the Administrator account for testing purposes.

Areca Config:

Hello

Volume Shadow Copy behavior on Windows XP is rather specific and is not supported by ArecaVSS.
We may address this feature in a future version, but it won't be available in the short term.

Best regards
