I accidentally deleted an iOS 14.4 backup in my Finder (replacement for iTunes in MacOS Big Sur). Is there a recycle bin or another location that this backup landed after I deleted it?
Unfortunately when you delete an iPhone or iPad backup from "manage backups" through the Finder, it does not go into the Trash.
The best way to get it back is to restore the iOS backup from your Time Machine backup that you made. (Assuming you have a Time Machine backup.) Otherwise you may be able to undelete with an App such as Disk Drill.
