AWS - S3 Fundamentals
You want to download all files from an S3 bucket folder backups/ to your local backup_local/ folder, but only files modified in the last 7 days. Which approach is best?
AUse 'aws s3 sync s3://mybucket/backups/ backup_local/ --exact-timestamps' and filter by date manually
BUse 'aws s3 cp s3://mybucket/backups/ backup_local/ --recursive' and then delete old files locally
CUse 'aws s3 rm' to remove old files before downloading
DUse 'aws s3api list-objects' with date filter, then download files individually
Step-by-Step Solution
Solution:
Step 1: Understand filtering by modification date
'aws s3 sync' and 'cp' do not support date filters directly.
Step 2: Use 'aws s3api list-objects' to filter by date
Listing objects with date filter allows selecting files modified in last 7 days, then download individually.
Step 3: Eliminate other options
Manual filtering or deleting is inefficient; 'rm' deletes files, not relevant here.
Final Answer:
Use 'aws s3api list-objects' with date filter, then download files individually -> Option D
Quick Check:
Date filtering requires list-objects + manual download [OK]
Quick Trick:Filter by date using list-objects, then download files [OK]
Common Mistakes:
MISTAKES
Expecting sync or cp to filter by date
Deleting files before download
Manual filtering after full download
