I’d like to find an older iCloud back up is that possible

iCloud only keeps on backup per device. If you have a computer backup you can find multiple versions.

Click on this link to discover how to 'Restore your iPhone, iPad, or iPod touch from a backup' --> https://support.apple.com/HT204184

or watch this video if you're using a Mac to do this:

Some things are not stored in a backup. Click on this link and read "About missing information after you restore your iOS device with iCloud Backup" -->

u can login to icloud.com and check the files / folders on the iCloud-Drive.

IF there are backups - one per device - you may find it there.

have you ever made a icloud-backup and was there space enough? Only 5 GB is free from Apple.
