Backup Scheduler

Automated and scheduled backup of a folder on macOS to AWS S3 using launchctl. I am using this to backup my Calibre library.

Setup

1. cp env.mjs.sample env.mjs and add values for AWS account ID (defensive check, so global profile changes don't accidently upload to another bucket), local folder, s3 bucket
2. Edit LaunchAgent-Examples/dev.zoid.calibre-backup-zx.plist and set correct path for node, index.mjs from your machine. By default, it runs on 30th minute of each hour, please feel free to change that behavior as well, relevant docs
3. cp ./LaunchAgent-Examples/dev.zoid.calibre-backup-zx.plist ~/Library/LaunchAgents or use symlink
4. launchctl load ~/Library/LaunchAgents/dev.zoid.calibre-backup-zx.plist (If load fails, try unload and then load)

Monitoring

• stdout - tail -f /tmp/dev.zoid.calibre-backup-zx.out
• stderr - tail -f /tmp/dev.zoid.calibre-backup-zx.err

Restore

To restore, you can use one the following commands

• aws s3 sync s3://<bucket> <local-folder>, docs
• aws s3 cp s3://<bucket> <local-folder> --recursive docs

Notes

• aws s3 sync doesn't remove files from the S3 bucket. It is add only.
