There is no proper backup solution for iPad, full stop. You can do it with cloud services but a single cloud service is not a proper backup. If there are any issues with this cloud's data integrity or your account to access the data it might all be inaccessible. Apple accounts have been wrongly closed (permanently) in the past with no recourse left for the users, and similarly this has happened with Google and Microsoft accounts as well.
When you put all your eggs in one basket meaning all your services are depending on a single account, any issue with that account, even if it's just account hijacking through phishing or something, can really grind everything to a halt.
Ok, so I can still have a local copy and backup external! I wasn't aware that could be done.
It is all very manual and complicated and prone to user error. In contrast Time machine actually Just Works. And supports incremental backups and keeping multiple versions properly tagged with date and time.
I really like Time Machine, guess its just a different work flow with an ipad
Yeah it is a worse workflow.
I would at the very least keep some kind of computer around, even if it's an old windows computer, as long as you can create local encrypted backups to quickly restore if the worst situation happens. Imagine your iPad gets stolen and your account gets locked and you need to access your work/data urgently. You can restore the backup offline to a new iPad and get access immediately. Although even that is limited because you absolutely need to buy another iPad to restore the backup.
I have a 2TB iPad and managing storage is challenging. Even with iCloud the Files app on the iPad constantly hangs, crashes, or interrupts copying, with over 1TB of data stored on my iPad I can confidently tell you that it's not even worth attempting to go without a Mac. You need the internet speeds to keep up with it too and internet access everywhere you need to access the cloud. Transferring a lot of small files over a SSD crashes the iPad as well sometimes, and I have the M4 iPad since launch day. The state of iPad is so embarrassing for Apple it's not even funny. You don't even get a progress bar when you copy things and good luck working with so much files in all the apps. Maybe you can do it if it's all just video to watch like TV shows, but actual data to work with in multiple apps on a daily basis, it's a frenzie of importing this, exporting that, copying to, copying from, unplugging this drive, plugging in that accessoire, remember you only got a single USB-C port to work with (though a USB hub would be supported or even a thunderbolt dock on the iPad Pro). But even that never worked for me, I tried it with a Belking TB dock and it would randomly disconnect devices.
I can guarantee nobody at Apple does serious work with the iPad. I really wanna know the percentage of Apple employees who have an iPad with 1TB or more of their data stored on it. That being said I am happy with the iPad due to the small footprint but I have a Mac as well and I use each one where they shine the most. Replacing the Mac with the iPad is not where the iPad shines the most. It can be done for some workflows.
