The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

最终实现效果:

1. 无版本概念,任何本地文件均可增量升级到最新.服务器不用管理多版本
2. 内存小,100M文件升级时只占用500KB内存.

使用流程:

1. 制作新版本,上传HTTP File Server.
2. Client自动计算差异,下载差异,合并差异.
3. done!
