## What it is
Attic is a deduplicating backup program written in Python that stores only changed data chunks, with optional AES-256 encryption and SSH-based off-site backups. Archives can be mounted as userspace filesystems for verification and restore.

## Use cases
- deduplicating daily backups of my files
- encrypted backup to a remote server over ssh
- mount a backup archive as a filesystem to restore files
- space-efficient incremental backups
- secure off-site backup from the command line

## When to choose
- you want efficient chunk-level deduplication so daily backups only store changes
- you need optional AES-256 encryption with HMAC-SHA256 integrity verification
- you want to back up over SSH to any remote host
- you prefer mounting archives via FUSE for easy verification

## When to avoid
- you want an actively developed tool - consider Borg, its maintained successor
- you need a GUI-based backup solution
- you require Windows support

## Facets
