## What it is
Plakar is an open-source backup engine written in Go that creates encrypted, deduplicated, independently verifiable snapshots of files, databases, Kubernetes workloads, and object stores. It stores snapshots in Kloset, an immutable data store, and is extensible through source/destination/storage integrations.

## Use cases
- back up my files with encryption and deduplication
- create browsable snapshots I can restore a single file from
- verify backups without restoring them
- protect servers against ransomware with immutable backups
- back up databases and Kubernetes workloads
- self-hosted alternative to commercial backup software
- diff two backup snapshots

## When to choose
- you need encrypted, deduplicated backups with no vendor lock-in
- you want independently verifiable, self-contained snapshots rather than chained incrementals
- you need to back up heterogeneous sources (files, databases, VMs, object stores) from one tool
- you prefer a cross-platform CLI with an open-source community edition

## When to avoid
- you need a GUI-first backup tool for end users
- you want continuous block-level disk imaging rather than file snapshots
- you require long-established enterprise support ecosystem only
