注：无git的方法参见：tar 或 7z 备份项目
首先利用homebrew安装p7zip
$ brew install p7zip
然后利用两个shell脚本：
- backupProject.sh 会在指定的项目文件夹中找到所有.git目录，对其git gc压缩，然后用7za创建两个7z文件：
- PROJECTDIR.2016-03-15-12-00-00.Src.7z
- PROJECTDIR.2016-03-15-12-00-00.gitpack.7z
- restoreProject.sh 会将上述两个文件用7za解压到目录：
- PROJECTDIR.2016-03-15-12-00-00.output
准备：
- 准备工作：首先用文本编辑工具打开 backupProject.sh 文件，修改项目名称 projPath=PROJECTDIR 和压缩密码 password=Demo 然后打开 restoreProject.sh 文件，修改解压缩密码 password=Demo
- 给两个 sh 脚本可执行权限：
chmod +x backupProject.sh restoreProject.sh
- 两个脚本与项目文件夹 PROJECTDIR 在同级目录
使用：
- 备份：
./backupProject.sh - 还原：
./restoreProject PROJECTDIR.2016-03-15-12-00-00.Src.7z
例子：
$ ls PROJECTDIR backupProject.sh restoreProject.sh // 备份 $ ./backupProject.sh Ready... git gc: PROJECTDIR/.git Nothing new to pack. git gc: PROJECTDIR/frameworks/.git ... git gc: PROJECTDIR/library/.git ... git gc: PROJECTDIR/Universal/.git ...

Done. $ ls PROJECTDIR PROJECTDIR.2016-03-15-12-00-00.Src.7z PROJECTDIR.2016-03-15-12-00-00.gitpack.7z backupProject.sh restoreProject.sh // 恢复 $ ./restoreProject.sh PROJECTDIR.2016-03-15-12-00-00.Src.7z Ready... Extracting PROJECTDIR.2016-03-15-12-00-00.Src.7z... ... Extracting PROJECTDIR.2016-03-15-12-00-00.gitpack.7z... ... Output Dir: PROJECTDIR.2016-03-15-12-00-00.output Done. $ ls PROJECTDIR PROJECTDIR.2016-03-15-12-00-00.Src.7z PROJECTDIR.2016-03-15-12-00-00.output PROJECTDIR.2016-03-15-12-00-00.gitpack.7z backupProject.sh restoreProject.sh $ ls PROJECTDIR.2016-03-15-12-00-00.output/ PROJECTDIR $
