As a general rule of thumb, it's always good to have a backup of your digital life, whether that's what's on your best iPhone or best iPad. That's because there is so much important data, memories, files, documents, and other sensitive information on our devices at any given time. These are, after all, basically considered our "lifeline." As far as backing up your iPhone or iPad, you can do it manually by connecting your device to your computer and backing it up in iTunes or Finder, or you can do it automatically every night via iCloud. I used to back up my devices manually, but I switched to automated iCloud backups a few years ago because, well, it's automatic, and it's one less thing to remember. However, it's not foolproof — you may encounter some issues backing up to iCloud every now and then. Here are some ways to troubleshoot the problem.
