Hi Farhad,
Thanks for reach out with your questions about Total Upkeep. Total Upkeep should actually translate into most languages. If you’re having trouble with this you can use a plugin like WPML to easily translate Total Upkeep to the language you desire.
As far as deleting backup from the dashboard you need to visit Total Upkeep<<Backups, find the file you wish to remove then select “View Details“. In the right-hand sidebar of this page beside the blue “Update” button there is an option to Delete backup. Just hit that link and follow the prompt to delete your backup archive file.
I hope this helps. Please reach back out if there is anything else we can answer for you.
