aws s3 sync

Recursively sync files and directories between your local system and an S3 bucket, or between S3 buckets. More information: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3/sync.html.

  • Sync files and directories from local to a bucket:

aws s3 sync {{path/to/file_or_directory}} s3://{{bucket_target_name}}/{{path/to/remote_location}}

  • Sync files and directories from a bucket to local:

aws s3 sync s3://{{bucket_source_name}}/{{path/to/remote_location}} {{path/to/file_or_directory}}

  • Sync objects between two buckets:

aws s3 sync s3://{{bucket_source_name}}/{{path/to/remote_location}} s3://{{bucket_target_name}}/{{path/to/remote_location}}

  • Sync local files to S3 while excluding specific files or directories:

aws s3 sync {{path/to/file_or_directory}} s3://{{bucket_target_name}}/{{path/to/remote_location}} --exclude {{path/to/file}} --exclude {{path/to/directory}}/*

  • Sync objects between buckets and delete destination files not in source:

aws s3 sync s3://{{bucket_source_name}}/{{path/to/remote_location}} s3://{{bucket_target_name}}/{{path/to/remote_location}} --delete

  • Sync to S3 with advanced options (set ACL and storage class):

aws s3 sync {{path/to/local_directory}} s3://{{bucket_name}}/{{path/to/remote_location}} --acl {{private|public-read}} --storage-class {{STANDARD_IA|GLACIER}}

  • Sync files to S3 and skip unchanged ones (compare size and modification time):

aws s3 sync {{path/to/file_or_directory}} s3://{{bucket_name}}/{{path/to/remote_location}} --size-only
