Description of my issue:
My original problem was that the cron backup on the SiteGround server gets killed due to a too high load. This I worked around by following the advice in the documentation for using the curl command and perform a frontend backup.
This lead me to the Options screen where I can setup a custom email message. One of the placeholders that can be used is [FILELIST]. However in the received email, the [FILELIST] placeholder remains empty, as in it is not replaced by anything. The backup itself however is successful.
A possible bug?
