Hi @Olman Yair Vasquez Mejia ,
please verify if the option Soft delete
is activated and if the deleted backups are visible in the Backup Items / soft deleted item
section.
From there it's possible to undelete the backups.
Delete soft deleted backup items permanently - Click Undelete
only.
If the backups aren't listed at soft deleted items the backups are "gone" and no chance to recover, as far as I know.
