Linux Backup and Recovery

Keep a recoverable off-site copy of important machine state as a tar + zstd + age archive uploaded to S3, and restore it after a reinstall or hardware loss.

Incremental snapshot backups of projects to a local backup drive using restic, with exclude rules for Linux development environments.

Validate a restic backup by restoring onto a clean external drive. Step by step disk preparation, restore execution, file verification, and safe unplug.
