Tutor:S3 Versioning allows you to keep multiple versions of an object in the same bucket. When versioning is enabled, S3 automatically creates a unique version ID for each object version. This helps protect against accidental deletion and overwrites.

Versioning & Lifecycle Policies

Author

Cloud Instructor.

S3 Versioning allows you to keep multiple versions of an object in the same bucket, protecting against accidental deletion and overwrites. Lifecycle policies automate the management of objects throughout their lifecycle, helping optimize storage costs.

S3 Versioning

When versioning is enabled, S3 automatically creates a unique version ID for each object version. You can retrieve any version of an object using its version ID. Versioning cannot be disabled, only suspended.

Lifecycle Policies

Lifecycle policies can transition objects between storage classes based on age, expire incomplete multipart uploads, and delete expired object delete markers. This provides comprehensive object lifecycle management and cost optimization.

Versioning & Lifecycle Policies Glossary

S3 Versioning
A feature that allows you to keep multiple versions of an object in the same bucket. Each version has a unique version ID and helps protect against accidental deletion and overwrites.
Lifecycle Policy
A set of rules that automate the management of objects throughout their lifecycle. Can transition objects to different storage classes or delete objects after a specified number of days.
MFA Delete
An additional security layer for versioning that requires your MFA device code to permanently delete an object version or change the versioning state of a bucket.
Version ID
A unique identifier automatically assigned to each object version when versioning is enabled. Used to retrieve specific versions of objects.
Lifecycle Transition
An action in a lifecycle policy that moves objects to a different storage class based on age. For example, moving objects to Standard-IA after 30 days or to Glacier after 90 days.
