/**
* Backup Memory Blocks to Local Files
*
* Exports all memory blocks from an agent to local files for checkpointing and editing.
* Creates a timestamped backup directory with:
* - Individual .md files for each memory block
* - manifest.json with metadata
*
* Usage:
* bun .letta/memory-utils/backup-memory.ts <agent-id> [backup-dir]
*
* Example:
* bun .letta/memory-utils/backup-memory.ts agent-abc123
* bun .letta/memory-utils/backup-memory.ts $LETTA_PARENT_AGENT_ID .letta/backups/working

If something goes wrong, you have two rollback options: If something goes wrong, restore from a previous backup:
### Option 1: Restore Memory Blocks Only
```bash ```bash
# Find the backup directory # Find the backup directory
ls -la .letta/backups/<agent-id>/ ls -la .letta/backups/<agent-id>/
# Restore from specific timestamp # Restore from specific timestamp

```
### Option 2: Full Agent Restore (Nuclear Option)
If memory restoration isn't enough, restore the entire agent from the .af backup:
```bash
# Find the agent backup
ls -la .letta/backups/<agent-id>/*.af
# The .af file can be used to recreate the agent entirely
# Use: letta --from-af .letta/backups/<agent-id>/<timestamp>.af
