After this I thought I should back up the iPad so I asked
ChatGPT:
"Can I perform a backup of the iPad (with its old OS)
into the Apple cloud?"
It replied:
------------------
Yes, you can back up your iPad to iCloud, even if it’s
running an older version of iOS. However, there are a few important
considerations when backing up to iCloud from an older device or iOS version:
How to Back Up Your iPad to iCloud:
Ensure iCloud Backup is Enabled:
Connect your iPad to a Wi-Fi network.
Make sure the iPad is plugged into a charger or has enough
battery.
Go to Settings > [your name] > iCloud > iCloud
Backup.
Toggle the iCloud Backup option to "On" if it’s
not already enabled.
Perform the Backup:
In the iCloud Backup settings, tap Back Up Now to begin the
backup process.
Make sure the process completes before you disconnect from
the Wi-Fi or charger.
The backup will include most of your app data, settings,
photos, and other information. However, there are some limitations:
App Data: If the iPad is running an old version of iOS, some
apps or app data might not be included in the backup, particularly if the apps
are no longer supported on that iOS version.
System and app updates: If you do a full restore after
activating the device or if you update the iOS version, some apps may need to
be updated to the latest version to work properly. If the apps you use to
control your lighting are no longer supported in newer versions of iOS, this
could be an issue.
Considerations for Backing Up on an Older iOS Version:
Old OS Compatibility:
iCloud backup will work with older iOS versions, but if you
are using very old apps, they may not sync or restore properly after an iOS
update.
If you plan to restore from iCloud after activation, make
sure the apps you need (like the lighting control software) are compatible with
the iOS version you're running.
Free iCloud Storage Limits:
If you have a lot of data on your iPad, you might run out of
iCloud storage. Apple’s free iCloud plan gives you 5 GB of storage, which may
not be enough for a full backup, especially if you have many photos or apps.
You can purchase additional iCloud storage if needed.
Backup Timing:
Make sure to back up before attempting activation or any
changes to your device. Once the device is activated and connected to iTunes or
iCloud, you can restore the backup if needed.
Alternatives if iCloud Backup Isn't an Option:
If you're concerned about backing up to iCloud or prefer a
local backup to your computer (iTunes or Finder), you can perform that as well:
Back Up with iTunes/Finder (Local Backup):
Connect the iPad to a Mac (or PC with iTunes).
Open iTunes (or Finder on macOS Catalina or later).
Select the iPad in the sidebar and choose Back Up Now.
This method will back up everything from your iPad to your
computer, which is especially useful if you’re concerned about iCloud
limitations or issues restoring the backup later.
Conclusion:
You can back up your iPad running an older iOS version to
iCloud, and it should back up most of your data and settings. However, if your
apps are older and not compatible with the latest OS versions, this could pose
a risk when restoring or activating the iPad. If you have concerns about
updating the OS after activation, you might want to back up to iTunes or Finder
on a Mac, as this will create a full, local backup without relying on iCloud’s
storage limitations.
-----------------
I therefore tried this but the backup failed, providing no
reason.
Conclusion
I can see that I'm living on 'borrowed time' with this
setup, and we need to use a different computer and software to get a more
robust solution for running the lighting. As I see it, there are two issues
with Apple products:
Firstly, You are completely at the whim of the developers,
who can and do change things which can completely change or remove one's own
ability to use a device. For example, I remember when we bought two of the
first iPhones which included Google Maps. After some period of time, Apple took
the unilateral decision to delete that application from iPhones. We had paid
for the products, and we owned them, and yet this important part of the phones'
functionality was removed.
The second problem is that a user cannot have absolute
control over their own data. Unlike the humble (for example) the humble
Raspberry Pi, one cannot take an image of one's Apple device and later do a
byte-for-byte restore of it. I appreciate that the majority of users may not
feel they need this, but I need to know with absolute confidence that I can get
our device back to a known state. That's not possible with the iPad it seems.
