This application backs up every folder mounted at `/data/` to a given AWS S3 path using the `aws s3 sync` command. It requires a pair of (IAM) Access and Secret Keys. You can supply the usual s3 sync parameters such as `--delete` and everything else. The cron schedule defines how often the sync command is executed, and it uses a lockfile to avoid parallel executions. This app has been based on the already available s3sync, however that was outdated, this version contains AWS CLI V2 and doesn't rely on extra python packages.
