With my email at least, I'm afraid to delete stuff. I just move old emails to folders (music, travel, video projects, etc.).
My reasoning being:
- There have been several instances where, for example, in 2020, someone writes me about a project and I do it. Then in 2024, they write back saying, "Do you still have the file I sent you in 2020? If so, please send my way" and I can say, "yes!" because it's right there in the folder. Yes, I know, this is improper management on the other person's part, but it's happened to me numerous times.
- Receipts, airline confirmation codes, etc. - always afraid to delete those, even after the purchase, trip, or whatnot. Never know when I get wrongfully charged, product never arrives, etc.
I may be too paranoid, so make fun of me all you want. I just want to be careful, that's all.
Rather than storing so much old email in iCloud, drag folders of it down to "On My Mac." You'll still have access to every bit of those emails but rarely-needed email won't be eating up huge space in iCloud. In example #1, you may not be able to send them that file immediately but only a few hours later when you get to your Mac.
You can also archive email very easily and then re-import archives if you need them again. And this can work out of and back into iCloud storage too. If Mac internal storage is tight, archive to a cheap external drive. Storage is cheap.
#2 is a short-term storage need. After the travel or return period, etc, it doesn't matter if you have immediate access to such stuff anymore. Nevertheless, it too can be moved from iCloud down to "On My Mac" to free up whatever iCloud space it holds without you losing access to any of it.
And it too can be archived on Mac vs. in iCloud so you can restore it back into email- iCloud or on my Mac- at any time if you had some reason to do so.
The Musical Scores thing is a much more valid use for cloud storage IF you are regularly evolving those scores. If the bulk of them are not being regularly edited but basically only for "read only" use, you can store them on your Mac and sync them to your iDevices. Then you have them with you on all devices without needing to use
any iCloud space.
But if you ARE regularly tweaking them, consider adopting a competing cloud service that will give you more than 5GB for free and store & access them there. This will free up most of the free 5GB from Apple to use for core service sharing like contacts, calendar, keychain, etc.
The four great data hogs of iCloud are:
- Photo libraries: store the library on Mac, create "best of" albums on Mac and sync the albums to iDevices
- Email: Purge the inbox down to always having relatively few emails in it and move archives of email to "On my Mac" if you must preserve every email you've ever received & sent.
- Messages (texts): Close text conversations when done vs. leaving them forever open to then pick up the conversation next time. All those cat videos, etc that are one-hit giggles, etc hog up a lot of iCloud space if you never close text messages... but if you "hang up" on the conversation when done, you keep purging such stuff from iCloud. Close text interactions when done, then start new ones next time- just like phone calls.
- iDevice backups: backup by attaching it to Mac from time to time and own, possess and control your own backups. This is dead simple and you leave for-profit strangers out of this part of things.
Other media like music & video can be synched too. Other kinds of files can be synched. In short, rather than paying forever rent for hard drives in the sky, you can own enormous HDD space attached to your Mac and manage it as we all did
before iCloud, not that many years ago. I would bet that most of the people with huge iCloud space don't ever bother to access almost all of what is eating up all that space. If true for you (reader), all that digital clutter could be preserved on cheap, no-rent-required HDD space in your computer, reserving iCloud space for only what you truly need to be stored in iCloud... which- for many- can be very little.
"Think different"... or pay forever.
