1.在server主机中把/etc目录打包压缩到/mnt中,名字为etc.tar.gz
[root@server /]# tar zcf /mnt/etc.tar.gz etc
[root@server /]# ll /mnt
total 8540
-rw-r--r--. 1 root root 8742561 Oct 10 07:32 etc.tar.gz
2.复制server主机中的etc.tar.gz到desktop主机的/mnt中
[root@server /]# cp /mnt/etc.tar.gz root@172.25.254.99:/mnt
cp: cannot create regular file ‘root@172.25.254.99:/mnt’: No such file or directory
[root@server /]# scp /mnt/etc.tar.gz root@172.25.254.99:/mnt
root@172.25.254.99‘s password:
etc.tar.gz 100% 8538KB 8.3MB/s 00:00
3.同步server主机中的/etc中的所有文件到desktop主机中/mnt中,包含链接文件
[root@server /]# cd /root/Desktop
[root@server Desktop]# rsync -lr /etc root@172.25.254.99:/mnt
root@172.25.254.99‘s password:
[root@server Desktop]# ll /mnt
total 8540
-rw-r--r--. 1 root root 8742561 Oct 10 07:32 etc.tar.gz
[root@desktop Desktop]# ll /mnt
total 8568
drwxr-xr-x. 133 root root 8192 Oct 10 07:40 etc
-rw-r--r--. 1 root root 8742561 Oct 10 07:36 etc.tar.gz
-rw-rw-r--. 1 student student 1690 Oct 10 00:57 file.all
-rw-rw-r--. 1 student student 815 Oct 10 00:55 find.err
-rw-rw-r--. 1 student student 30 Oct 10 00:54 find.out
-rw-rw-r--. 1 student student 30 Oct 10 01:04 find.out.1
