 ====== How to copy files \ directories  \ filesystems via network. ====== ====== How to copy files \ directories  \ filesystems via network. ======
-That small article give a view of content copying task via network.\\  +The article describes ways of copying content over network. 
-I want do this on my homeserver upgrade, copy all info from working "old" server, to "new" server partition, for can make access a data and config files, for bring "new" server in state it looks be similar of "old" one, before switch "old" off, and set "new" instead it.\\  +
-In examples, i work from "new" server CLI, it has IP 192.168.0.14 \\ +
-"Old" server has IP 192.168.0.1, both in in one subnet.\\ +
-Both, "ssh" and "scp" commands work via secure shell ( ssh ) protocol, port 22, and must be enabled "sshd" on computer where we connect.+
  
 +When upgrading a home server, I copy all the data from the old server to a new system. In the examples below, I work from the new server and both servers are on the same subnet:
 +  * New server (IP: 192.168.0.14)
 +  * Old server (IP: 192.168.0.1) 
  
 +Both the ''ssh'' and ''scp'' commands communicate over a secure connection (TCP port 22). Please note that you need to enable the ''sshd'' daemon on the remote host.
  
-====== Files \ single folder copying ====== 
- If you need a copy of standalone files or folders, you can use an scp util:\\  
  
-''scp -r -v -p root@192.168.0.1:/etc /From_Old_Server'' \\ 
  
-There: +====== Copy Files / Directories ====== 
-   -r key do recursive , copy all data in "/etc" folder and all its subfolders. +If you need to copy single files or directoriesyou can use the ''scp'' command:\\ 
-  *  -p key preserve file attributeslike a creation, modification times. +
-  *  -v gives us verbose output. \\+
  
- In there example we copy "/etc" folder from 192.168.0.1 computer ( actually, "Old" server), to folder "/From_Old_Server" in local computer "new" server).\\ +<code> 
 +scp -r -v -p root@192.168.0.1:/etc /local_dir 
 +</code> 
 + 
 +Flag explanation: 
 +  *  -r: recursive (copy all the content of ''/etc'' including its subdirectories) 
 +  *  -p: preserve file attributes (egfile creation or modification times) 
 +  *  -v: verbose output
  
-Sadly, but that command scp cannot copy whole system disk, contains "/proc""/dev" and even "/lost+found" catalog, who is it in every mounted extX filesystem partition - at that places "scp" stuck and stops.\\ +In the example above we copy the ''/etc'' directory located on a remote host (the old server: 192.168.0.1to ''/local_dir'' on the local host ("newserver)
  
-Thanks to Patrick"Volkerdi" gives us workaround for that situation:+Please note that the ''scp'' command cannot copy the whole file system hierarchy including ''/proc''''/dev'' or ''/lost+found''. Fortunately, there is a workaround which was [[http://www.linuxquestions.org/questions/slackware-14/copy-whole-filesystem-via-scp-4175449321/#post4887869|provided]] by Patrick Volkerding.
  
-====== Copy whole filesystem ======+====== Copy whole filesystem hierarchy ======
  
-command +The following command should successfully copy a whole filesystem hierarchy: 
 <code bash> <code bash>
-ssh root@192.168.0.1 "(cd / ; tar cf - . )" | (mkdir -p /From_Old_Server ; cd /From_Old_Server ; umask 000 ; tar xvf -)+ssh root@192.168.0.1 "(cd / ; tar cf - . )" | (mkdir -p /local_dir ; cd /local_dir ; umask 000 ; tar xvf -)
 </code> </code>
  
-help us transfer full filesystems without stuck and pain from "old" to "new" computer.
