Currently we’re using s3cmd to copy one bucket to another to backup. Rather than doing a full copy is there a way to do an incremental copy/sync so that only changed/new files are moved and deleted ones removed? I was looking into s3sync as that seems more appropriate but it seems to sync only between local and bucket not bucket to bucket. If anyone could give me some advice as to how to backup one bucket to another that’d be very helpful. 1 bucket is in NA and the other in EU for disaster purposes. We’d like to do a nightly backup of the NA bucket to EU. Both buckets are set up already.
