Does it mean that we have no enough disk space locally to create tar file?
Thank you in advance!

Hi,
DRS doesn't support OpenSSH client alive message, causing backup failure | |
Symptom: Error seen during DRS. The DRS CCMDB log file then shows:/bin/tar: -: Cannot write: Broken pipe /bin/tar: Error is not recoverable: exiting now CCMDB Backup failed, unable to tar data to master agentConditions: Using DRS to back up CUCM servers to an OpenSSH SFTP server with "client alive messages" enabled. (This is enabled in the OpenSSH sshd_config configuration file. The two parameters in question are "ClientAliveCountMax" and "ClientAliveInterval". http://www.openbsd.org/cgi-bin/man.cgi?query=sshd_config&sektion=5 )Workaround: Disable "client alive messages" on the Open SSH serverORSet the ClientAliveCountMax and ClientAliveInterval to a high enough count / interval so the server doesn't timeout the connection to CUCM during the backup. On one system the following values were found to allow for successful backups: ClientAliveInterval 40 ClientAliveCountMax 3Further Problem Description: When "client alive messages" is enabled, the OpenSSH SFTP server sends periodic "client alive" messages and expects a response from the SFTP client. If the client doesn't respond to ClientAliveCountMax client alive messages, the SFTP server disconnects the session. The ClientAliveInterval parameter determines how often these client alive messages are sent.The problem is that the DRS SFTP connection doesn't respond to these client alive messages. Therefore, if during the course of the backup there is a sufficiently long interval without any data being transferred (45 secs in the customer's configuration) the SFTP session gets closed and the backup errors out with the error shown above. |

Hi,
What are the supported SFTP Servers to perform backup and restore?
Make sure that Cisco Unified Communications Manager is running. In a cluster, make sure that Cisco Unified Communications Manager is running on all servers in the cluster. To back up data to a remote device on the network, you must have an SFTP server configured. The following SFTP servers are supported and recommended, but you may use any SFTP server:
•Open SSH (for Unix systems, refer to http://openssh.com)
•Cygwin (refer to http://sshwindows.sourceforge.net/, or http://ipc-platform-team.cisco.com/index.cgi/DrfInfo/faq) ;
•freeFTPD (Currently not supported due to a file size limitation of 1GB)(refer to http://www.freeftpd.com/?ctt=download, or http://ipcbu-cap.cisco.com/tips/SFTP%20server.html)
•TitanFTP (http://www.webdrive.com/products/titanftp/index.html)
•In addition to the free sftp servers mentioned below, GlobalScape is the commercial SFTP Server that have been certified with Cisco through the Cisco Technology Developer Partner program (CTDP). More info refer to http://www.globalscape.com/gsftps/cisco.aspx.\\

Hi,
Please refer the below link,
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a0080b1b10f.shtml
DRF backup failed with this error message:
/bin/tar: -: Cannot write: Broken pipe /bin/tar: Error is not recoverable: exiting now CCMDB Backup failed, unable to tar data to master agent Restoring CAR services ...
This issue is documented in Cisco bug ID CSCte62205 (registered customers only)
As a workaround try one of these steps:
Disable client alive messages on the Open SSH server
Set the ClientAliveCountMax and ClientAliveInterval to a high enough count / interval so the server does not timeout the connection to CUCM during the backup.
Restart the DRF Master Agent(MA)/DRF Local Agent (LA).
Hope this helps.
Anand

Thank you!
Can you please explain what is Open SSH Server? Also ...so the server does not timeout the connection to CUCM during the backup. - which server is it?

Oh, I see now
The thing is that I use Core FTP mini sftp server software. It is free and very simple, there are no options in it, just User/Password and Path
Does it mean that this software was developed on the basis of OpenSSH SFTP Server and I have to find another sftp server software?

Keep in mind our transfer is a pretty large transfer therefore we use keepalives for tgr SSH session, not all ftp servers support it. The best is a linux server with openssh in my opinion, I think on the forums theres a document on how to setup one with Ubuntu.
