Copy-S3Object -BucketName test-files -Key sample.txt -DestinationKey sample-copy.txt -DestinationBucket backup-files

Contoh 3: Perintah ini mengunduh objek "sample.txt" dari bucket “test-files” ke file lokal dengan nama "local-sample.txt “.


Copy-S3Object -BucketName test-files -Key sample.txt -LocalFile local-sample.txt

Contoh 4: Mengunduh objek tunggal ke file yang ditentukan. File yang diunduh akan ditemukan di c:\downloads\data\archive.zip
