How can I migrate CarrierWave files to a new storage mechanism?

Question

I have a Ruby on Rails site with models using CarrierWave for file handling, currently using local storage. I want to start using cloud storage and I need to migrate existing lo

Answer 1

I have migrated the Carrier wave files to Amazon s3 with s3cmd and it works.

Here are the steps to follow:

1. Change the storage kind of the uploader to fog.
2. Create a bucket on Amazon s3 if you already dont have one.
3. Install s3cmd on the remote server sudo apt-get install s3cmd
4. Configure s3cmd s3cmd --configure. You would need to enter public and secret key here, provided by Amazon.
5. Sync the files by this command s3cmd sync /path_to_your_files ://bucket_name/
6. Set this flag --acl-public to upload the file as public and avoid permission issues.
7. Restart your server

Notes:

sync will not duplicate your records. It will first check if the file is present on remote server or not.
