I did an upgrade to my iPad2 last year and it crashed, losing my music and backups. My first and last Apple product.
I thought all users got iCloud for backups, something that is real automatic. I’ve already restored a fresh iPad completely from the cloud that Apple automatically includes. I really have no idea why your cloud backup didn’t work.
But, talking about your music ... I have music from the time that iTunes started - and when I got my iPad ... it was ALL THERE even though it had never been on an iPad before!
AND ... all the TV shows and movies were there too! What a deal!
You may have not realized it, but you don’t lose your music - it’s always “in the cloud” and it can always be restored.
I also got a free alternate backup with Dropbox - just for good measure and it ALSO does ALL DATA backup. It’s just amazing!
If you want to, I can show you how to get your iTunes music back and also show you how to do the restore from Apple’s cloud, and also show you how to get some additional and free backup from Dropbox, and so on.
How is that even possible? Your iPad crashed and you lost your backups? Exactly WHERE were you keeping these backups that your iPad crash could lose them????
