## What it is
Snapper is a Linux command-line tool for managing filesystem snapshots, supporting creation, deletion, comparison, and rollback of snapshots on filesystems like Btrfs and LVM. It lets users view older versions of files and undo system changes such as package updates or configuration edits.

## Use cases
- create and manage btrfs snapshots on linux
- undo a bad package update or config change
- compare snapshots to see which files changed
- roll back system to a previous state without full backup restore
- automatically snapshot before zypper transactions
- let non-root users restore old file versions

## When to choose
- you run Linux with Btrfs, LVM, or ext4 and want snapshot-based rollback
- you want automatic snapshots around package management on openSUSE
- you need file-level comparison and undo without full backups

## When to avoid
- you need cross-machine backups or offsite copies - snapshots are not backups
- you are on a filesystem or OS Snapper does not support
- you want a GUI-only solution

## Facets
