Identify the exact key and version
Use the complete object key and version identifier from the storage inventory or event record. Similar filenames, prefixes, and URL-encoded characters can make a near match look correct while targeting a different object.
Inspect the selected version's size, timestamp, and metadata before restoring. If the current object was changed by a lifecycle rule or delete marker, understand whether the restore operation creates a new version or modifies the existing history.
Restore and verify the result
Prefer a documented copy-to-current or recovery action that preserves the old version when possible. Check destination encryption, access policy, content type, and metadata because a byte-identical object can still behave differently if its headers change.
Read the restored object and compare checksum or other integrity evidence, then verify consumers can access it. Record the operator, version, and recovery time, and retain the prior current version until the result is confirmed.
