Daylight Savings time and SnapServer functionality

    We have a service pack (SP3) available for GuardianOS powered servers running GuardianOS 4.2.054 or higher which will update your server to reflect this change.

     

    GuardianOS 4.2.054 SP3 can be downloaded http://www.adaptec.com/en-US/speed/external_storage/snap/guardianos_4_2_054_sp_3_gsu.htm

    Please note that you must have GuardianOS 4.2.054 or higher in order to apply the service pack. If you are not at this revision you will need to first upgrade your server. Please contact technical support for assistance with upgrading.

    This could also potentially affect 3rd party backup mechanisms that rely on file time. SnapOS servers attached to a domain will not be affected as they will sync to your network time. For SnapOS servers in a workgroup you can configure the server to update via a public NTP server.
