Redis

Manual RDB backup # Trigger RDB save kubectl -n storage exec redis-shared-master-0 -- redis-cli -a SAVE # Copy RDB file kubectl -n storage cp redis-shared-master-0:/data/dump.rdb ./redis-backup-$(date +%Y%m%d).rdb Manual AOF backup # Trigger AOF rewrite kubectl -n storage exec redis-shared-master-0 -- redis-cli -a BGREWRITEAOF # Copy AOF file kubectl -n storage cp redis-shared-master-0:/data/appendonly.aof.1.base.rdb ./redis-aof-$(date +%Y%m%d).rdb Restore # Copy backup file to pod kubectl -n storage cp ./redis-backup-20260512.rdb redis-shared-master-0:/data/dump.rdb # Restart pod to reload RDB kubectl -n storage delete pod redis-shared-master-0 # Redis will load dump.rdb on startup ⚠️ Redis data is ephemeral cache — for most apps, losing Redis is inconvenient but not catastrophic. Prioritize PostgreSQL backups.

Minio

Prerequisites alias mc='kubectl -n storage exec deployment/minio -- mc' mc config host add myminio http://minio.storage.svc:9000

Backup a bucket mc mirror myminio/my-bucket ./backups/my-bucket/ Restore a bucket mc mirror ./backups/my-bucket/ myminio/my-bucket Backup all buckets (script) for bucket in $(mc ls myminio | awk '{print $NF}'); do echo "Backing up $bucket ..." mc mirror myminio/$bucket ./backups/$bucket/ done Scheduled backup (CronJob) apiVersion: batch/v1 kind: CronJob metadata: name: minio-backup namespace: storage spec: schedule: "0 4 * * *" jobTemplate: spec: template: spec: containers: - name: backup image: m.daocloud.io/docker.io/minio/mc:latest command: - sh - -c - | mc alias set myminio http://minio.storage.svc:9000 $ACCESS_KEY $SECRET_KEY mc mirror myminio/ ./backup/$(date +%Y%m%d)/ env: - name: ACCESS_KEY valueFrom: secretKeyRef: name: minio key: root-user - name: SECRET_KEY valueFrom: secretKeyRef: name: minio key: root-password volumeMounts: - name: backup mountPath: /backup restartPolicy: Never volumes: - name: backup hostPath: path: /data/backups/minio

N8N

Tue, 12 May 2026 15:00:59 +0800

Method 1: Web UI Export (Recommended) N8N 内置了工作流导入导出功能：登录 https://n8n.72602.online 进入 Workflows 列表页面勾选需要备份的工作流点击 Download → 导出为 JSON 文件如需恢复，点击 Import from File Method 2: API Export # 获取所有工作流 curl -s -u : https://n8n.72602.online/rest/workflows \ | jq . > n8n-workflows-$(date +%Y%m%d).json Method 3: PostgreSQL Database Backup N8N 的工作流定义存储在 PostgreSQL 中。备份 PG 即可包含 N8N 数据： pg_dump -U postgres -h postgresql.database n8n > n8n-db-$(date +%Y%m%d).sql N8N 的凭证（Credentials）包含 API key 等敏感信息，建议在 Export 时选择 Include Credentials 并妥善保管导出的文件。

Open WebUI

Tue, 12 May 2026 15:00:59 +0800

Backup Chat History (SQLite) Open WebUI 的数据默认存储在 SQLite 数据库中： # 备份数据库文件 kubectl -n ai exec open-webui-0 -- cat /app/backend/data/webui.db > open-webui-$(date +%Y%m%d).db Restore # 复制备份文件到 pod kubectl -n ai cp open-webui-20260512.db open-webui-0:/app/backend/data/webui.db # 重启 pod 以重新加载数据库 kubectl -n ai delete pod open-webui-0 注意事项备份文件包含：聊天记录、用户设置、外部连接配置不包含：对话中的文件附件（存储在 static/uploads/ 目录）如需完整恢复，还需备份上传文件： kubectl -n ai exec open-webui-0 -- tar czf - /app/backend/data/uploads > open-webui-uploads-$(date +%Y%m%d).tar.gz

Uptime Kuma

Tue, 12 May 2026 15:00:59 +0800

Backup via Web UI Uptime Kuma 内置了备份功能：登录 https://uptime.72602.space 进入 Settings → Backup 点击 Export → 下载 JSON 文件备份文件包含：所有监控项、状态页配置、通知设置 Restore 登录 Uptime Kuma 进入 Settings → Backup 点击 Import → 选择之前下载的 JSON 文件确认后自动恢复所有配置注意事项备份文件不包含监控历史数据，只包含配置历史数据存储在 SQLite 数据库中（/app/data/kuma.db） Uptime Kuma 的 PVC 没有自动备份。2026-10-01 恢复时，旧 PVC/PV 已不存在，仓库中也没有 UI 导出或 SQLite 备份；当前实例使用全新的空数据库，原监控项、通知设置和历史记录无法从集群恢复。重新创建 ZJLAB Push 监控后，必须把新生成的 Push URL 更新到 ECS 私有配置中；不要继续使用旧 URL。如需保留历史，可以备份 SQLite 文件： kubectl -n monitor exec deploy/uptime-kuma -- cat /app/data/kuma.db > kuma-backup-$(date +%Y%m%d).db
