CUCM 7.x Backup

[CHARLES HEUPEL]

Trying to configure backup on cucm 7.0 to a linux sftp server.  I know the network and file path are good but I keep getting an error that the server is to slow to respond.  When I try connecting to the server with an sftp client, it prompts me to accept the ssh keys and I'm wondering if this is why I can't connect with CUCM.  Is there a way to tell CUCM to accept the keys if prompted from the GUI or command line?

Hello Charles,

CUCM backup method only uses that simple authentication mechanism => username / password.

I know that didn't help, but there are only some vendors that are supported by cisco for backup and recovery:

From http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/drs/8_0_2/drsag802.html

To back up data to a remote device on the network, you must have an SFTP server that is configured. Cisco allows you to use any SFTP server product but recommends SFTP products that have been certified with Cisco through the Cisco Technology Developer Partner program (CTDP). CTDP partners, such as GlobalSCAPE, certify their products with specified version of Cisco Unified Communications Manager. For information on which vendors have certified their products with your version of Cisco Unified Communications Manager, refer to the following URL:

For information on using GlobalSCAPE with supported Cisco Unified Communications versions, refer to the following URL:

#

Cisco uses the following servers for internal testing. You may use one of the servers, but you must contact the vendor for support:

#

•Open SSH (refer to http://sshwindows.sourceforge.net/)

#

•Cygwin (refer to http://www.cygwin.com/)

#

•Titan (refer to http://www.titanftp.com/)

#

Cisco does not support using the SFTP product freeFTDP. This is because of the 1GB file size limit on this SFTP product.

You can also use FTPD for backup, but it has a 1 GB limit. For example the database could be greater than 1 GB.

Are you really sure about this Marcel?  Cisco may not support it, but I've pushed files MUCH larger than 1 GB using FreeFTPD on many occasions.  It is the most widely used SFTP server product among all the engineers I know.

I'm not saying you're wrong, but I've never seen anything that stated this prior to your post.  Do you have a link to something that states this?

Hello Clifford,

here in the forum are some posts describing the 1GB problem. Also there is an open issue CSCsy72201.

Charles,

I haven't seen this particular problem, but I can offer a possible workaround.

You should only need to accept the keys one time.   You should be able to do a manual file push to the SFTP server (and thus accept the key), using the file get command.  Try this from the CLI of the server:

file get activelog mohprep/SampleAudioSource.xml

It will then ask you a series of questions, and download the file to the SFTP server.  If it needs it, it will prompt you for to accept the key.  I believe

Once you've accepted it, it shouldn't prompt you for it again (at least it didn't when I tested this in my lab).  I'm betting that if you do this, you should then be able to get your SFTP server to work IF THAT WAS THE PROBLEM.

Thanks Cliff....I'll give that a try and see if it works.  Will let you know.
