In case if you want to view the old backup
which are there in the iCloud and also if you want to delete the backup then what you
do is go to “Settings”. Now tap on the name at the top here. Go to “iCloud”. Select “Manage storage”. Wait for few seconds. Now go to “backups”. Now you can see there are two devices which
are currently backed up in my iCloud. So, if I want to delete any backup, I will
select it and then I can select “Delete backup”. So, this is how you can find out what devices
are backed up in the iCloud and then delete it.
