Glacier Backup

App to backup your files in S3 Glacier Deep Archive storage made using Go.

Requirements

• Go 1.16 installed in your computer
• AWS account
• Create a S3 bucket
• API key and secret key in the ~/.aws/credentials

Setup

1. Execute make install to build the application and create the required folders.
2. This command will create:

• An application glacier-backup in your /usr/local/bin folder
• A folder in $HOME/.glacier-backup directory with the config.yaml file.

3. Define the configuration params in your $HOME/.glacier-backup/config.yaml file
4. Run in your terminal executing:

glacier-backup

5. If you need to stop the process you can use Ctrl + V and the backup process will continue where it stopped.

Develop

This application has no infrastructure requirements (DB, cache) so to develop you can run simply the cmd/main.go file.

To prevent upload the same files that are already uploaded, the application uses a CSV list of uploaded files. This list (uploaded_files.csv) is stored in the same bucket and it contains a list of uploaded files + the uploaded date.

If you executes the command again and some files have the updated_at date after the uploaded_date from the CSV file they will be updated in the remote bucket.

TODO list

• Add testing
• Add more remote storages (eg. Cloud Storage) implementing the RemoteFilesRepository interface and adding the custom configuration params in the var/config.yaml file.
