Which Era component collects logs and snapshots from the database?

The Nutanix Era Time Machine is the core component responsible for data protection. It captures and manages a complete, chronological copy of the database, which includes database snapshots and transaction log backups. The Time Machine uses this collected data to enable Point-in-Time Recovery (PITR), allowing administrators to clone or restore the database to any specific moment. The schedule for this collection is defined by a Service Level Agreement (SLA), and the tasks are executed by the Era agent on the database VM.

A. Profiles are templates containing software, compute, network, and database parameter configurations used for provisioning, not for collecting data.
B. The Era Database Agent is a service on the DB server that executes tasks commanded by Era, but the Time Machine is the logical component that manages the collected data.
C. SLAs define the schedule and retention policy for snapshots and log collection but are not the component that performs the collection itself.

1. Nutanix Era 2.5 User Guide, "Time Machine Management," Section: "Time Machine Overview". It states, "A time machine in Era is a set of snapshots and log backups of a specific database."

2. Nutanix University, "Nutanix Database Administration (NDA) v2.0," Module 3: Era Architecture and Configuration, Lesson: "Era Constructs". This lesson describes the Time Machine as the entity that stores snapshots and logs for a database.
