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 v22+
• awscli 1.8.6+ (for support of STANDARD_IA storage class)
• find
• gpg
• tar

Install

• aws configure

• npm ci

• bin/backup-to-cloud init

• Modify your new config file

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

• Try a scan first with: bin/backup-to-cloud scan --dry

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

• Set up some crontab entries for it, for example:

  • run every hour with verbose logging:

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

  • run backup every 12 hours:

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

  • run scan every day:

  0 7 * * * cd /path/to/this && ./bin/backup-to-cloud scan >> cron-scan.log 2>&1
