Hi there. I've been using s3cmd for years but have only just started using s3cmd --sync to keep a 5Gb folder with 19,000 images synced with S3.
Would someone clarify how the sync option works? On each run does it calculate a md5 of every local file and then pull the corresponding md5 from the S3 metadata to compare? Or does it store the local md5s somewhere and only recalculates when a local file changes? The reason I ask is that running the sync can take a long time (40+ minutes) before any changes are listed and start to sync. The hosting company my client is with charges horrendously for international bandwidth (we're based in New Zealand) so I want to make sure that doing a sync only uses a small amount of bandwidth (pulling md5s etc) to make the comparison before uploading any changes.
