我正在尝试这个命令
tar cvpzf /TEMP_BACKUPS/backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/tmp --exclude=/TEMP_BACKUPS --exclude=/mnt --exclude=/sys / > /TEMP_BACKUPS/mylog.txt
我收到了这个错误.我试了两次

我需要做什么来进行完整备份
解决方法
请注意,您的tar命令已成功完成;它只是抱怨套接字条目. Tiffany建议使用一种机制来过滤掉那些特定的错误消息,尽管tar仍会以错误代码退出.
您还可以将一组套接字提供给tar的-X选项,以将它们从备份中排除,例如：
# find / -type s -print > /tmp/sockets-to-exclude # tar cvpzf /TEMP_BACKUPS/backup.tgz -X /tmp/sockets-to-exclude \ --exclude=/proc --exclude=/lost+found --exclude=/tmp \ --exclude=/TEMP_BACKUPS --exclude=/mnt --exclude=/sys / > /TEMP_BACKUPS/mylog.txt
这种技术的优点是它使tar的退出代码更有用(也就是说,你可以使用退出代码来决定备份是否成功完成).
您还可以通过将其他–exclude选项替换为单个-X(也称为–exclude-from)并简单地将它们列在文件中来缩短命令行.
