I’m an old guy and don’t understand it! But I’m not the only one. I was in the Microsoft store wondering about Office 365. The young guy helping me was talking about how storage on the cloud (”Onedrive” is what MS calls it) is encrpyted at 4 or 5 different levels. He went on and on about the various levels, digits of encryption, etc.
“Okay - but what about backups?”
“Every time you want to access a file it is backed up before you even open it. So it is always backed up.”
“Okay - but what if the server crashes or a fire or electrical outage?”
“Well - it’s on the cloud so that isn’t a worry.”
“Um - it still has to be on a server somewhere. I suppose they have it all backed up on other servers elsewhere?”
“Oh - I don’t know. I guess.”
For most purposes "the cloud" is secure and protects data with multiple copies, in some form to include formal back-ups.
IF you use a brand name provider or know enough to know what questions to ask.
But, in the cloud it's NEVER safe from government access, with or without warrant.
That’s understandable, but you’re not trying to conceal illicit activity, now are you? If you plan to use technology to hide your wrongdoings, at least try to comprehend the basics of said technology.
