What are the key considerations for backing up data in a serverless architecture?

Agent-based backups require software (an agent) to be installed on the system being backed up, which allows for more granular control and advanced features. Agentless backups, on the other hand, use existing infrastructure and do not require agent software on each individual system.

Factors that differentiate agent-based from agentless backups include:

1. Granularity: Agent-based backups offer more granular control over what specific data is being backed up, making them suitable for environments where specific data needs to be managed differently.

2. Resource Usage: Agentless backups typically require fewer resources as they leverage existing infrastructure for backups, whereas agent-based backups may require more resources on the individual systems being backed up due to the agent software.

3. Scalability: Agentless backups can be easier to scale across multiple systems as they do not require the installation and management of agents on each system. This can be advantageous in large, complex environments.

4. Security: Agent-based backups may offer more control over security settings and access rights since the agent software can be specifically configured for each system.

5. Management Complexity: Agentless backups can be simpler to manage since they do not require individual agent installations and configurations. This can be beneficial for environments with a large number of systems to backup.

Scenarios that may favor agent-based backups include environments where:

– Granular control over specific data is required.

– Security settings need to be closely managed on a per-system basis.

– Individual system configurations make agentless backups
