备份与恢复

Synapse 提供完整的导出/导入，用于记忆备份、迁移与灾难恢复。本指南覆盖核心操作。

导出

完整 Mind 导出

将某个 Mind 的所有记忆导出为 JSON：

curl -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/memory/mind-export > backup.json

响应格式：

{
  "mind_id": "m_xyz789",
  "mind_name": "Work Mind",
  "exported_at": "2026-06-27T...",
  "memory_count": 142,
  "memories": [
    {
      "id": "mem_001",
      "category": "identity",
      "key": "user_name",
      "content": "Michael Schäfer",
      "tags": ["person", "identity"],
      "priority": "critical",
      "source": "user",
      "verified": true,
      "created_at": "2026-06-15T...",
      "updated_at": "2026-06-27T..."
    }
  ]
}

增量导出（Diff）

仅导出自某时间戳以来变化的记忆：

SINCE=$(date -d "2026-06-01" +%s)
curl -H "Authorization: Bearer YOUR_MIND_KEY" \
     "https://synapse.schaefer.zone/memory/diff?since=$SINCE" > incremental.json

响应：

{
  "added": [...],
  "updated": [...],
  "deleted": [...]
}

自动化备份

通过 cron 调度每日备份：

curl -X POST https://synapse.schaefer.zone/cron \
  -H "Authorization: Bearer YOUR_MIND_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "schedule": "0 2 * * *",
    "endpoint": "https://synapse.schaefer.zone/memory/mind-export",
    "method": "GET",
    "headers": {"Authorization": "Bearer YOUR_MIND_KEY"}
  }'

更好：外部备份脚本

#!/bin/bash
# backup-synapse.sh
MIND_KEY="${SYNAPSE_MIND_KEY}"
DATE=$(date +%Y%m%d)
BACKUP_DIR="/backups/synapse"

mkdir -p "$BACKUP_DIR"

curl -s -H "Authorization: Bearer $MIND_KEY" \
     https://synapse.schaefer.zone/memory/mind-export \
     > "$BACKUP_DIR/synapse-$DATE.json"

# 保留最近 30 天
find "$BACKUP_DIR" -name "synapse-*.json" -mtime +30 -delete

echo "Backup saved: $BACKUP_DIR/synapse-$DATE.json"

加入 crontab：

0 2 * * * /usr/local/bin/backup-synapse.sh

恢复

恢复到同一 Mind

# 解析备份并逐条重新 POST 记忆
jq -c '.memories[]' backup.json | while read mem; do
  curl -X POST https://synapse.schaefer.zone/memory \
    -H "Authorization: Bearer YOUR_MIND_KEY" \
    -H "Content-Type: application/json" \
    -d "$(echo "$mem" | jq '{category, key, content, tags, priority}')"
done

恢复到新 Mind

# 1. 创建新 Mind
NEW_KEY=$(curl -s -X POST https://synapse.schaefer.zone/minds \
  -H "Authorization: Bearer YOUR_JWT" \
  -H "Content-Type: application/json" \
  -d '{"name":"Restored Mind","description":"Restore from backup"}' \
  | jq -r .mind_key)

# 2. 将记忆导入到新 Mind
jq -c '.memories[]' backup.json | while read mem; do
  curl -X POST https://synapse.schaefer.zone/memory \
    -H "Authorization: Bearer $NEW_KEY" \
    -H "Content-Type: application/json" \
    -d "$(echo "$mem" | jq '{category, key, content, tags, priority}')"
done

Python 恢复脚本

import json
import requests

URL = "https://synapse.schaefer.zone"
MIND_KEY = "mk_..."

def restore(backup_file):
    with open(backup_file) as f:
        data = json.load(f)
    
    for mem in data["memories"]:
        requests.post(
            f"{URL}/memory",
            headers={
                "Authorization": f"Bearer {MIND_KEY}",
                "Content-Type": "application/json"
            },
            json={
                "category": mem["category"],
                "key": mem["key"],
                "content": mem["content"],
                "tags": mem.get("tags", []),
                "priority": mem.get("priority", "normal")
            }
        )
    
    print(f"Restored {len(data['memories'])} memories")

restore("backup.json")

在 Mind 之间迁移

def migrate_memories(source_key, target_key):
    """把源 Mind 中的所有记忆迁移到目标 Mind。"""
    # 从源导出
    r = requests.get(
        f"{URL}/memory/mind-export",
        headers={"Authorization": f"Bearer {source_key}"}
    )
    data = r.json()
    
    # 导入到目标
    for mem in data["memories"]:
        requests.post(
            f"{URL}/memory",
            headers={
                "Authorization": f"Bearer {target_key}",
                "Content-Type": "application/json"
            },
            json={
                "category": mem["category"],
                "key": mem["key"],
                "content": mem["content"],
                "tags": mem.get("tags", []),
                "priority": mem.get("priority", "normal")
            }
        )
    
    print(f"Migrated {len(data['memories'])} memories")

备份其他数据

别忘了备份：

验证

恢复后请验证：

# 统计记忆数量
curl -s -H "Authorization: Bearer $KEY" \
     https://synapse.schaefer.zone/memory/stats | jq .total

# 与备份对比
jq .memory_count backup.json
