我正在使用rsync从我的linux服务器备份一百万张图像到我的电脑(使用Cygwin的Windows 7)。
我现在使用的命令是:
rsync -rt --quiet --rsh='ssh -p2200' root@X.X.X.X:/home/XXX/public_html/XXX /cygdrive/images
每当进程中断并重新启动时,启动复制过程需要很长时间。 我认为如果有任何更新,它会检查每个文件。
我的服务器上的图像一旦创建就不会改变。
那么,有没有更快的方法来运行命令,以便它可以复制文件,如果本地文件不存在而不检查文件大小,时间,校验和等...
请建议。
谢谢

你是否试过这个标志 - 这可能有所帮助,但可能还需要一些时间才能恢复转移:
--ignore-existing
This tells rsync to skip updating files that already exist on the destination (this does not ignore
existing directories, or nothing would get done). See also --existing.
This option is a transfer rule, not an exclude, so it doesn't affect the data that goes into the
file-lists, and thus it doesn't affect deletions. It just limits the files that the receiver requests
to be transferred.
This option can be useful for those doing backups using the --link-dest option when they need to con-
tinue a backup run that got interrupted. Since a --link-dest run is copied into a new directory hier-
archy (when it is used properly), using --ignore existing will ensure that the already-handled files
don't get tweaked (which avoids a change in permissions on the hard-linked files). This does mean that
this option is only looking at the existing files in the destination hierarchy itself.
