    Symptoms

    Backup works and backup activities appear in the activities list. Archives were created in the target location (you can check them using Backups page in Management console or by browsing the target folder using any file browser).

    But you receive alerts "Backup did not start" or you see that date and time of backup creation does not match the backup plan settings.

    Troubleshooting

    Let's briefly review the process from the task creation/task being applied moment until the backup start.

    Main points:

    • The backup plan contains information about the time when the backup should start (in case the backup plan doesn't contain any scheduled events it can be started manually).
    • The backup plan is forwarded to Acronis Agent / Acronis Appliance from Acronis Management Server and works independently (even if the Agent/Appliance loses connection to Acronis Management Server). The backup plans are stored in the scheduler database.
    • The scheduler component on Agent/Appliance executes the tasks according the system time on the machine where it is installed
    • Acronis Backup shows an alert in case the backup plan stored on the server side has a pre-scheduled time for the task start, but if Acronis Management Server didn't recieve any messages related to that event from the Acronis Agent side.

    As such, there are two main possible root causes for Backup did not start alerts:

    • a communication issue between components
    • time settings on Server and/or Agent sides are incorrect

    In case the Agent/Appliance is online and no communication issues were detected, then we have to check all the time settings: on Acronis Management Server, on machine with Acronis Agent and/or on Acronis Appliance and VM-HOST.

    Windows

    • In case any Acronis Agent installed on Windows system (Agent for Windows, Agent for VMware for Windows) the scheduler uses Windows system time
    • Acronis Management Server uses Windows system time as well

    Windows system time can be changed using Windows Date and Time settings in Control Panel

    Linux

    • Acronis Agent for Linux uses Linux system time
    • Acronis Management Server for Linux uses Linux system time

    Linux system time can be checked using date command in the Linux terminal.

    Please check how to set the system time settings according to the system you use.

    Acronis Appliance

    System time for Acronis Appliance depends on several settings:

    1. System time on ESX/ESXi host

    ESX/ESXi host uses UTC time. Acronis Appliance, as a guest system, receives the time settings from the ESX/ESXi host .

    The time on ESX/ESXi host can be checked using the date command runned from ESX/ESXi host command line. 

    For more information please check the following articles in VMware knowledge base:

    *If you see in the ESX/ESXi host settings your local time via vSphere Client it means that the time from ESX/ESXi host was converted in vSphere Client according the time zone on the machine where the vSphere Client is running at the moment.

    **If the ESX/ESXi host time doesn't match the local time on the vSphere Client's machine (after all internal time zone calculations) then the Date & Time setting on host will be marked red.

    2. Time zone settings on the Appliance

    By default, Acronis Appliance uses internal time of ESX/ESXi host (UTC time zone), but Appliance time zone can be corrected in the Acronis Appliance graphical interface. 

    Information about the time zone and the time can be received from Appliance shell using the date command (press Ctrl + Shift + F2 to reach the shell in Appliance graphical interface).

    Thus, Acronis Appliance gets the time from the ESX/ESXi host and corrects it using the time zone from own settings.

    All-In-One Appliance

    Basically All-In-One Appliance is a CentOS-based virtual machine with pre-installed Acronis Backup Server, Acronis Backup Agent for Linux and Acronis Backup for VMware for Linux.

    System time can be set using the System time feature on the Cockpit page of All-In-One System (Cockpit is available on http://AIO_IP_ADDRESS:9090).

    All components (Acronis Management Server, Acronis Backup Agent for Linux and Acronis Backup for VMware for Linux) use the mentioned system time.

    For more information about All-In-One Appliance please check product documentation.

    In case all the above settings were checked, but the issue persists, please collect the following information and contact Acronis Customer Central with a reference to this article:

    1. System information from Acronis Management Server and from the Agent or Appliance that generates the alert
    2. Screenshots of time and date settings on Acronis Management Server and from the Agent that generates the alert (or output of date command on Appliance)

    Additional information

    Last backup and Next backup columns on the Devices page of Management Console shows the time of the backups according the time zone of the browser you use to connect to Acronis Management Server.

    For example:

    • you have UTC+2 time zone on Acronis Management Server and a backup plan with scheduled start on 1 PM
    • in case you connect to Acronis Management Server using the browser/machine with UTC+4 time zone, you will see 3 PM in the column Next backup
