Disaster Recovery & Workspace Rollbacks ​

DevDiff provides an automated local Disaster Recovery Engine to protect developer codebases against broken AI refactoring, corrupt AST states, or unapproved multi-file edits.

How Checkpoints Work ​

DevDiff automatically records a snapshot fingerprint before executing any AI-assisted operation:

💾 Created Pre-AI Checkpoint: ckpt-1719000300-def456

Snapshots reside locally inside .devdiff/memory/snapshots/ and are strictly private to your local workstation.

Recovery Steps ​

Step 1: List Available Checkpoints ​

bash
devdiff recover list

Output:

Available Workspace Checkpoints:
  ID: ckpt-1719000300-def456  Time: 2026-08-08 22:10:00  Files: 5
  ID: ckpt-1719000120-abc123  Time: 2026-08-08 22:05:00  Files: 2

Step 2: Restore a Specific Checkpoint ​

bash
# Revert workspace to pre-AI state
devdiff recover --checkpoint ckpt-1719000300-def456

Clearing Old Checkpoints ​

To free local disk space, clear historical recovery snapshots:

bash
# Delete recovery snapshots older than 24 hours
devdiff recover clean --older-than 24h
