Contoh 1: Perintah ini menyalin objek "sample.txt" dari bucket “test-files” ke bucket yang sama tetapi dengan kunci baru "sample-copy.txt “.

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

Contoh 2: Perintah ini menyalin objek "sample.txt" dari bucket “test-files” ke bucket “backup files” dengan kunci "sample-copy.txt “.

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

Copy-S3Object -BucketName test-files -Key data/archive.zip -LocalFolder c:\downloads

Contoh 5: Download semua objek yang cocok dengan key prefix yang ditentukan ke folder lokal. Hirarki kunci relatif akan dipertahankan sebagai subfolder di lokasi unduhan keseluruhan.
