  PLESK_ERROR: Backup failed. Operation canceled by user.

Cause

The option Pre-post data capture causes Acronis to run a pre-command which fails, therefore the backup also fails to create.

Resolution

1. Log into Plesk > Acronis Management Panel > Backup Console > All devices > Backup Plan name > click the gear icon > Backup > click the gear icon > Backup Options
2. Switch to the Pre-post data capture commands tab and disable the option by selecting NO.
3. Press DONE to save changes.
4. Press SAVE CHANGES to apply the setting for the backup plan.
