User=wapps. Restoring Backup

[wapps]

Do I have to reset my account before doing a full backup restore, or will the full backup restore overwrite everything I currently have. I want to go back to the state of the full backup.

I just read this in Wiki:  "Backups cannot be restored directly in Plesk using the 'Restore' button. To restore a backup, you must first extract the backup file on your local machine, then upload the specific parts you need."

It sounds like backup will not do what I thought it would. It appears that backup will restore only files and not settings (e.g., php, php composer).  Is this correct?

By the way, what is the 'Restore' button for if it is not to restore the backup?

Plesk itself is capable of restoring backups (and in fact, unarchiving an account is exactly this), but we don't allow user-created/user-supplied backups to be restored for security reasons, as it's possible to tamper with the backups in a manner such that they would compromise the server when restored.

Only the admin-created backup available from https://heliohost.org/backup/ (or the archive from an account that was previously archived) can be restored automatically, and an admin has to do it for you.

Totally confused.   <1> I went to my Backup Manager and saw that there is no Restore button.  <2> Wiki states, "To restore a backup, you must first extract the backup file on your local machine, then upload the specific parts you need."  I unziped the backup file I downloaded to my home computer and looked at the files.  The files have no meaning to me.  How would I know which "specific parts" to upload?  see attached picture of files in backup file. <3> Was I suppose to have an admin make a backup of my files? Can I request an admin to restore a backup file in my Backup Manager?  Why is there a Backup Manager?  <4> My original question is still not addressed: Do I have to reset my account before doing a full backup restore, or will the full backup restore overwrite everything I currently have. I want to go back to the state of the full backup.
