在期望脚本中同步VirtualBox目录时rsync挂起

Question

当r-同步VirtualBox目录时，我的期望脚本无法继续。

下面是脚本：

#!/usr/bin/expect -f 

     spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Documents/ username@server:/home/username/BAK/Documents/ 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/AndroidDev/ username@server:/home/username/BAK/AndroidDev/ 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Android/ username@server:/home/username/BAK/Android/ 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Videos/ username@server:/home/username/BAK/Videos/ ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/VirtualBox\ VMs/ username@server:/home/username/BAK/"VirtualBox\ VMs/" ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/james/Pictures/ username@server:/home/username/BAK/Pictures ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn scp -v /home/james/.vimrc username@server:/home/username/BAK/ ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn scp -v /home/james/.bashrc username@server:/home/username/BAK/ ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn scp -v /home/james/.profile username@server:/home/username/BAK/ ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

     spawn scp -v /home/james/.xsession* username@server:/home/username/BAK/ ; 
     expect "password:" 
     send "thepassword\r" 
     interact 
     sleep 1 

如果我改变spawn rsync -vruEtl --progress -h --log-file=rsync.log --fuzzy --stats /home/rschostag/VirtualBox\ VMs/ remote@server:/home/directory/BAK/VirtualBox到spawn scp -vr /home/rschostag/VirtualBox\ VMs/ remote@server:/home/directory/BAK/VirtualBox，它的工作原理。但是，我不想每次都进行完整备份。

增量备份此目录或使rsync命令正常工作的最佳方式是什么？

谢谢！

按照要求，请找的expect -d script输出如下：

$ sudo expect -d rsync_backup 
expect version 5.45

这是它挂起，并且不提供，我可以识别的错误消息。

我移动了远程的VirtualBox目录并重新启动了备份，并在运行备份几天后最终完成。备份的总大小为71 GB。我用expect -d运行它，它在终端中输出一个非常详细的输出，所以这是有帮助的，因为没有-d的脚本可能看起来像挂了，因为它没有在输出中打印任何东西。所以，我相信，除了没有任何进展迹象之外，没有任何错误，这让我相信它可能没有用。

谢谢你给我提供关于expect -d选项的建议。

这是新的脚本作品：
