How to manually verify Windows 10 iTunes Backup?

There is no verify function. See Archive iPhone backup in Windows - Apple Community to make copies. I'd recommend backing up to both iTunes and iCloud for some redundancy.

Hey there SunnyInToronto,

While we're unsure of what you're asking regarding how to 'verify' an iTunes backup on your Windows PC, we do have a link that shows how to locate backups: Locate backups of your iPhone, iPad, and iPod touch

Regarding your question about what an iCloud backup contains, it's a good thing to remember that anything already syncing with iCloud is synced back to a device that you're setting up and/or restoring, regardless of having a backup or not. That being said, this second link shows what an iCloud backup would contain: What does iCloud back up?

Depending upon how much data you're syncing from iCloud, it can take some time when setting up a new device. This is also true of an iTunes backup. Depending on how big the backup is from which you're restoring/setting up a new device, it can take some time to finish restoring from a backup from whichever location you choose.

If you need more help, or after reviewing the details/links above, let us know more details. We'll be ready to assist however we can.

Cheers!
