  • N

    near-continuous data protection (near CDP)

    Near-continuous data protection, sometimes called near-continuous protection, is a general term for backup and recovery products that take snapshots at set intervals. The term evolved from a need to differentiate products that take snapshots on a pre-determined schedule (every fifteen minutes, for example) from those products that take snapshots each time new data is written (true CDP).

  • O

    online data backup (remote data backup)

    Online data backup (remote data backup) is a method of off-site storage in which data is regularly backed up over a network on a remote server, typically hosted by a provider.
