Backup setups provide everything necessary to have cloud or local backups in place. A cloud backup is provided through a purchased service like Google Drive or Carbonite. A local backup is set up with an external hard drive and software such as Windows backup, Veeam, or Urbackup.
"If you have crucial or important data that you want to preserve, having a backup is highly recommended to minimize the risk of losing data. Types of data that can be backed up are important files, computer images, pictures, music and documents."
What's needed for this service:
An external drive with enough space to save files (local)
Backup software (local) Or cloud subscription
Data must be readable (local and cloud)
