Auto Sync Buckets Cheatsheet

1. Create a file auto-sync-file.sh and create a folder auto-sync-logs to store the logs.

2. auto-sync-file.sh should contain the following:

   #!/bin/bash
   aws s3 sync s3://my-bucket-destination s3://my-bucket-source --source-region us-west-2 --regio
   n us-west-2
   

3. Configure your crontab to the following, this will run the auto-sync-file.sh script and write the logs to auto-sync-logs. Then every week it will delete the older logs.
