Zephyr Insurance needs an alternative site for its claims system. Its tolerable downtime is 4 hours and budget is limited. It rejects a hot site as too costly. It proposes a site with hardware and connectivity installed but no live data, with data to be restored from backups on arrival. What is the main implication of this choice?

Choosing a warm site lowers cost but lengthens recovery, because data and configuration must be restored from backups. Zephyr must test whether this can be done within its 4-hour tolerance, and it remains fully dependent on reliable backups.

  1. ARecovery within minutes with no data loss
  2. BRecovery time longer than a hot site, driven by restoring data and configuration, which may threaten the 4-hour toleranceCorrect
  3. CNo need for any backup procedures
  4. DCost identical to a hot site but with lower security

Explanation

A site with equipment but without current data is a warm site. It is cheaper than a hot site but recovery depends on loading backups, so time and data currency are worse. Zephyr must test that restoration fits within 4 hours. It still depends entirely on good backups.
