Cloud backup stores copies of data in cloud storage so the data can be restored after deletion, corruption, device failure, ransomware, or another problem.
What can be backed up?
Backups can include files, databases, virtual machines, application data, configuration, and whole system snapshots. The right backup method depends on what must be recovered.
Backup and recovery goals
Backup plans often use RPO and RTO to define how much data loss and downtime are acceptable.
A backup is only useful if it can actually be restored when needed.
