iCloud & Device Syncing
Whether it's backing up your phone, or syncing your data and photos across devices, once set-up properly iCloud is a valuable service available free to all Apple customers.
iCloud is Apple's Internet based suite of services allowing you to backup and sync data across all your devices. All Apple accounts have 5GB of free online storage space, with extra storage starting at just 79p/month.
iPhone & iPad Backup
Gone are the days of having to remember to plug your iPhone or iPad into your computer to back it up. All recent versions of iOS have the capability to run backups automatically to your iCloud account whenever your device is plugged in and online.
These days iCloud has meant that managing photos across all your devices has become very simple. Once set up the iCloud Photo Library gives you a single archive of all your photos, regardless of what they were taken with, available to view across all your devices. This uses your iCloud storage as a shared photo store, increasing the available space on your iPhone or iPad.
Contacts & Calendars
You can use iCloud to sync your contacts and calendar entries across all your devices, so if you add an entry on your iPhone it will appear within seconds on your iPad and Mac, completely automatically.
