backup-to-cloud

A simple backup tool which uploads encrypted files to S3, in batches.

Ideally, it should be setup to run in a crontab entry.

Features

• Encrypts files locally with gpg
• Uploads files to S3 in batches of customizable size
• Support for uploading a tar archive of files in certain folders, useful for sources with thousands of files (e.g. photo library)
• Rescans sources at specific intervals to find new or updated files
• Removes files from S3 if they are removed locally

Requirements

• OS: Linux, MacOS (untested)
• node.js 10+
• awscli 1.8.6+ (for support of STANDARD_IA storage class)
• find
• gpg
• tar

Install

• aws configure

• yarn install --production OR npm install --production

• cp config.sample.js config.default.js

• Modify your new config file

• Check your config file: bin/backup-to-cloud --check-config

• Try it out first with: bin/backup-to-cloud --dry

• Set up a crontab entry for it, for example:

  • run every hour with verbose logging:

  0 * * * * cd /path/to/this && ./bin/backup-to-cloud --verbose >> cron.log 2>&1
  

  • run every 12 hours:

  0 */12 * * * cd /path/to/this && ./bin/backup-to-cloud >> cron.log 2>&1
