Symptoms

You receive an email notification about a failed backup.

You check Acronis True Image user interface and all indicates that all backups have completed successfully :

• green check box is displayed on each backup
• backup completion confirmation is displayed under Activity tab for each backup
• a new recovery point under Recovery tab is added as date and time of a successful backup (right upper corner)

Cause

Issue with product configuration. Acronis Scheduler attempts to run a non-existent backup task.

Solution

You need to delete traces of the non-existent backup task manually. This can be achieved either by clearing up the schedule and reconfiguring backups or by searching for the the faulty script and deleting it manually.

Method 1

This method is easier but you will need to re-define backups' schedule afterwards (backups themselves and all the settings except for the schedule will be preserved)

1. Download Acronis Scheduler Manager, right-click it and select Run as administrator
2. Run the following command in Scheduler Manager:

   task zap

3. In Acronis True Image user interface, click on each backup that you want to be run automatically by schedule, click on the Options button, re-enter the desired schedule for backups and save changes
4. See if the issue is resolved and you no longer receive false alarms about failed backups by email.

Method 2

This method is more complicated, includes additional cleanup action (Scripts folder), but no backup reconfiguration is required afterwards. It consists of deleting configuration files - leftovers from previous backup tasks in the Scripts folder, and their corresponding entries in Acronis Scheduler.

1. Turn off Acronis Active Protection temporarily
2. Delete configuration files of non-existing tasks:
   1. 1. Open the Scripts folder at C:\ProgramData\Acronis\TrueImageHome\Scripts. This folder contains files with GUID names such as 3DBBFDBC-9BE0-4E54-9B39-F261D8A7C3CE. Each file represents either a backup task or an automatic post-backup validation task.
         
      2. Open each file with Notepad or other text editor (right-click -> Open with....) and find their display and uuid parameters. Display parameter corresponds to the backup task name, seen in Acronis True Image interface, or an automatic post-backup validation task. Uuid is a unique identifier of the task, it also matches the script's file name. Delete files, that do not have a corresponding task in the product's user interface.
         In our example, if we would see, say, "My pictures" in between <display> and </display>, we would delete that file, because we do not see such backup in Acronis True Image user interface.
3. Delete tasks in Acronis Scheduler, that do not have a corresponding script file:
   1. Download Acronis Scheduler Manager, right-click it and select Run as administrator
   2. Run the following command in Scheduler Manager:

      get list

      The program will display the list of the tasks. Look at uuid after the /script: part:
      

   3. You will need to delete the tasks, whose uuids do not exist in the Scripts folder by their numbers from the first column.
      In the example above we take tasks with numbers 1-3, 1-4, 1-5 and 1-7 (seen at the left edge of the picture), then see which of them are missing the corresponding scripts by their uuids and delete those entries in Scheduler Manager using the following commands:

      task [number]

      task delete

      For example, if the task 1-3 (uuid 24DF111B-845C-4186-A9D6-0292B09A5AF4) is lacking a script file (C:\ProgramData\Acronis\TrueImageHome\Scripts\24DF111B-845C-4186-A9D6-0292B09A5AF4.tib.tis), we would delete this record:

      task 1-3

      task delete

   4. Tasks that do not have a /script: part in Acronis Scheduler Manager's output are harmless and can be kept.

4. Turn on Active Protection back.
5. See if the issue is resolved and you no longer receive false alarms about failed backups by email.
