Would love to understand what 3-2-1 means please.
Simply put.
3 copies of anything critical.
2 types of media
This is more difficult for non business as non HDD storage is expensive but one cloud backup can work instead.
1 copy stored off site.
Having three copies at home is not much help if your house burns down etc.

Thank you!
One thing it doesn't mention is that a sync is not a backup. If deleting a file in one copy of the data triggers a delete in another copy, then it doesn't count as a copy.
The right sync is actually an excellent backup, and compliments other methods (like local storage) quite nicely.
Any worthwhile sync will delete to a recycle bin and support versioning of files. A bad actor would have to have account level access to dump the recycle bin, which proper use of MFA can limit in the majority of cases.
A sync will also make it easier to propagate files to an offsite copy, as you can have a connected device in a separate location.
One of the most important aspects in backups is convenience. Anything that is a task or chore risks getting put off - I see it all the time.
I guess I didn't get my point across. I wasn't tryig to say it can't happen automatically, just that if deleting it in one copy als, deletes it in another then it's useless in an accidental deletion scenario. Having versioned deletion is different and would mean the file was not deleted.
