Rsync for file server backup

　　 For company file server scp When I ordered the backup, it broke because the cleaner cleaned the keyboard for me in the morning , Checked for a while , There is no way to continue , It's too troublesome to transfer one folder by one ,scp The default is to overwrite , So I want to find a document that can be compared , And skip the backup command of the same file , After searching and querying the command parameters , It is recorded as follows ：

　　 command ：rsync

　　 With the parameters ：

　　-a --archiive Archiving mode , Indicates that files are transferred recursively , And keep all file properties , be equal to -rlptgoD

　　-v --verbose Detailed mode output

　　-z --compress Compress the backup files during transmission

　　-u --update Just update it , That is to skip all that already exists in DST, And the file time is later than the file to be backed up , Do not overwrite updated files

　　--progress View the copy process

　　 The specific example commands are as follows ：

　　rsync -avzu --progress MEEN/ [email protected]:/home/wood/PROJECT/

　　 Be careful ：

　　 If the path has spaces , Must use "" Circle

　　 Both servers that have to talk are installed rsync
