Cloud storage backup is a strategy for backing up data that involves removing data offsite to a
managed
service provider for protection. It can either replace or complement on-premise backups.
A major benefit of using cloud backup is that it
can make managing a backup system easier. Data moved offsite should be deduplicated to
speed the backup and encrypted for protection. The
service provider can use an initial seeding option to speed up the first online backup. Seeding
works by placing the initial backup on an appliance and sending it to the provider to upload. After
that, only incremental changes get backed up to the cloud. Customers can use their own backup
software and hardware for the first step, or use an appliance and software supplied by a service
provider.
