PLESK_ERROR: Backup failed. Operation canceled by user.
The following error can be found when download activity log from Backup error > Details > Download log:

Option Fail the backup if the command execution fails is enabled in Plesk > Acronis Management Panel > Backup Console > All devices > example.com > click the gear icon > Backup > click the gear icon > Backup Options > Pre-post data capture command.
The option Pre-post data capture causes Acronis to run a pre-command which fails, therefore the backup also fails to create.

- Switch to the Pre-post data capture commands tab and disable the option by selecting NO.
