Amazon Glacier Delete Archive

See more Amazon Glacier Examples

Demonstrates how to delete an archive from a vault. You can delete one archive at a time from a vault. To delete the archive you must provide its archive ID in the delete request. You can get the archive ID by downloading the vault inventory for the vault that contains the archive. Pascal (Lazarus/Delphi)
