amazon web services - AWS S3 copy to bucket from remote location -


there large dataset on public server (~0.5tb, multi-part here), copy own s3 buckets. seems aws s3 cp local files or files based in s3 buckets?

how can copy file (either single or multi-part) s3? can use aws cli or need else?

there's no way upload directly s3 remote location. can stream contents of remote files machine , s3. means have downloaded entire 0.5tb of data, computer ever hold tiny fraction of data in memory @ time (it not persisted disc either). here simple implementation in javascript:

const request = require('request') const async = require('async') const aws = require('aws-sdk') const s3 = new aws.s3() const bucket = 'nyu_depth_v2' const baseurl = 'http://horatio.cs.nyu.edu/mit/silberman/nyu_depth_v2/' const parallellimit = 5 const parts = [   'basements.zip',   'bathrooms_part1.zip',   'bathrooms_part2.zip',   'bathrooms_part3.zip',   'bathrooms_part4.zip',   'bedrooms_part1.zip',   'bedrooms_part2.zip',   'bedrooms_part3.zip',   'bedrooms_part4.zip',   'bedrooms_part5.zip',   'bedrooms_part6.zip',   'bedrooms_part7.zip',   'bookstore_part1.zip',   'bookstore_part2.zip',   'bookstore_part3.zip',   'cafe.zip',   'classrooms.zip',   'dining_rooms_part1.zip',   'dining_rooms_part2.zip',   'furniture_stores.zip',   'home_offices.zip',   'kitchens_part1.zip',   'kitchens_part2.zip',   'kitchens_part3.zip',   'libraries.zip',   'living_rooms_part1.zip',   'living_rooms_part2.zip',   'living_rooms_part3.zip',   'living_rooms_part4.zip',   'misc_part1.zip',   'misc_part2.zip',   'office_kitchens.zip',   'offices_part1.zip',   'offices_part2.zip',   'playrooms.zip',   'reception_rooms.zip',   'studies.zip',   'study_rooms.zip' ]  async.eachlimit(parts, parallellimit, (key, cb) => {   s3.upload({     key,     bucket,     body: request(baseurl + key)   }, cb) }, (err) => {   if (err) console.error(err)   else console.log('done') })
