Description: `
|
||
备份功能。支持备份本地文件到云盘，备份云盘文件到本地，双向同步备份三种模式。支持JavaScript插件对备份文件进行过滤。
|
||
指定本地目录和对应的一个网盘目录，以备份文件。网盘目录必须和本地目录独占使用，不要用作其他用途，不然备份可能会有问题。
|
||
|
||
备份功能支持以下三种模式：
|
||
1. upload
|
||
备份本地文件，即上传本地文件到网盘，始终保持本地文件有一个完整的备份在网盘
|
||
2. download
|
||
备份云盘文件，即下载网盘文件到本地，始终保持网盘的文件有一个完整的备份在本地
|
||
3. sync（慎用！！！双向备份过程会删除文件）
|
||
双向备份，保持网盘文件和本地文件严格一致
|
||
|
||
请输入以下命令查看如何配置和启动：
|
||
aliyunpan sync start -h

Usage: "启动sync同步备份任务",

UsageText: cmder.App().Name + " sync start [arguments...]",
|
||
Description: `
|
||
备份本地文件到文件网盘，或者备份文件网盘的文件到本地。支持命令行配置启动或者使用备份配置文件启动同步备份任务。
|
||
|
||
配置文件保存在：(配置目录)/sync_drive/sync_drive_config.json，样例如下：
|
||
{
|
||
"configVer": "1.0",
|
||
"syncTaskList": [
|
||
{
|
||
"name": "设计文档备份",
|
||
"localFolderPath": "D:/tickstep/Documents/设计文档",
|
||
"panFolderPath": "/sync_drive/我的文档",
|
||
"mode": "upload",
|
||
"priority": "time"
|
||
}
|
||
]
|
||
}
|
||
相关字段说明如下：
|
||
name - 任务名称
|
||
localFolderPath - 本地目录
|
||
panFolderPath - 网盘目录
|
||
mode - 模式，支持三种: upload(备份本地文件到云盘),download(备份云盘文件到本地),sync(双向同步备份)
|
||
priority - 优先级，只对双向同步备份模式有效。选项支持三种: time-时间优先，local-本地优先，pan-网盘优先
|
||
|
||
例子:
|
||
1. 查看帮助
|
||
aliyunpan sync start -h
|
||
|
||
2. 使用命令行配置启动同步备份服务，将本地目录 D:\tickstep\Documents\设计文档 中的文件备份上传到云盘目录 /sync_drive/我的文档
|
||
aliyunpan sync start -ldir "D:\tickstep\Documents\设计文档" -pdir "/sync_drive/我的文档" -mode "upload"
|
||
|
||
3. 使用命令行配置启动同步备份服务，将云盘目录 /sync_drive/我的文档 中的文件备份下载到本地目录 D:\tickstep\Documents\设计文档
|
||
aliyunpan sync start -ldir "D:\tickstep\Documents\设计文档" -pdir "/sync_drive/我的文档" -mode "download"
|
||
|
||
4. 使用命令行配置启动同步备份服务，将云盘目录 /sync_drive/我的文档 和本地目录 D:\tickstep\Documents\设计文档 的文件进行双向同步
|
||
同时配置同步优先选项为本地文件优先，并显示同步过程的日志
|
||
aliyunpan sync start -ldir "D:\tickstep\Documents\设计文档" -pdir "/sync_drive/我的文档" -mode "sync" -pri "local" -log true
|
||
|
||
5. 使用命令行配置启动同步备份服务，将本地目录 D:\tickstep\Documents\设计文档 中的文件备份到云盘目录 /sync_drive/我的文档
|
||
同时配置下载并发为2，上传并发为1，下载分片大小为256KB，上传分片大小为1MB
|
||
aliyunpan sync start -ldir "D:\tickstep\Documents\设计文档" -pdir "/sync_drive/我的文档" -mode "upload" -dp 2 -up 1 -dbs 256 -ubs 1024
|
||
|
||
6. 使用配置文件启动同步备份服务，使用配置文件可以支持同时启动多个备份任务。配置文件必须存在，否则启动失败。
|
||
aliyunpan sync start
|
||
|
||
7. 使用配置文件启动同步备份服务，并配置下载并发为2，上传并发为1，下载分片大小为256KB，上传分片大小为1MB
|
||
aliyunpan sync start -dp 2 -up 1 -dbs 256 -ubs 1024
|
||
|
||
8. 当你本地同步目录文件非常多，或者云盘同步目录文件非常多，为了后期更快更精准同步文件，可以先进行文件扫描并构建同步数据库，然后再正常启动同步任务。如下所示：
|
||
aliyunpan sync start -step scan
|
||
aliyunpan sync start
