Rollback Snapshot

Restore a BTRFS subvolume to a previous snapshot.

When to use

Undoing a system change (config, package, file edit)

Reverting after an unsuccessful upgrade

Emergency restore from a known-good state

Inputs to gather

Snapper config name

Source snapshot ID (the state to roll back to)

Target snapshot ID (usually 0 for current)

Procedure

Preflight: Verify snapper is installed and config exists. Warn if rolling back root filesystem (requires reboot).

Run sudo snapper -c <config> undochange <src>..<tgt> in dry-run mode (list affected files).

Display the list of files that will be reverted. Request explicit user confirmation.

On confirmation: Run sudo snapper -c <config> undochange <src>..<tgt> (destructive mode, no flag).

If root filesystem: print reboot reminder.

Output / side effects

Subvolume reverted to snapshot state. May require reboot if root filesystem.

Safety / constraints

Destructive operation. Always show dry-run listing first. Requires explicit confirmation. Root-FS rollback warns about reboot. Requires sudo.
