Our Analysis
The backup tool that actually makes you want to run backups. Restic is fast, encrypted by default, and works with 20+ storage backends — S3, Backblaze B2, SFTP, local disk, you name it. If you're an indie hacker who knows they should back up their VPS but haven't gotten around to it, restic removes every excuse. BorgBackup is the main competitor — slightly better deduplication, but locked to SSH/local storage. Duplicati has a web UI but is slower and less reliable. Tarsnap is encrypted and paranoid-grade but expensive. Commercial options like Backblaze and Acronis are simpler but cost more at scale. Restic's killer feature is incremental, deduplicated backups with client-side encryption. Your cloud provider never sees your data unencrypted. Restores are fast because it stores snapshots, not diffs. The catch: no built-in scheduling — you need cron or systemd timers. No web UI for monitoring. The forget/prune workflow for cleaning old backups is powerful but confusing for newcomers. And if you lose your encryption key, your backups are gone forever. No recovery option.
Packer builds machine images so you don't have to. Define your AMI, Docker image, or VM template as code, and Packer creates identical images across AWS, GCP, Azure, VMware, and more from a single config. Immutable infrastructure starts here. If you're deploying to cloud VMs and want reproducible, version-controlled images, Packer is the standard tool. Docker handles containerized workloads and is the modern default for most teams. Ansible/Chef/Puppet configure existing machines rather than baking images. Cloud-native image builders (EC2 Image Builder, GCP's image tools) exist but lock you into one provider. The multi-cloud story is Packer's killer feature. One template, images for every cloud. The HCL config language is clean, and the plugin system extends it to basically any target. The catch: HashiCorp switched Packer to the BSL license in 2023, which means competitors can't offer it as a service. For your own use it's fine, but the license shift spooked the open-source community. Also, if you've gone all-in on containers, you probably don't need Packer at all — Dockerfiles replaced it for many teams.
