UCM Backup

hello All

I have a 10 server cluster running ucm 7.1.3 32900-4

when i try to run a backup the DB errors out at 50%

/bin/tar: -: Wrote only 4096 of 10240 bytes

/bin/tar: Error is not recoverable: exiting now

CCMDB Backup failed, unable to tar data to master agent

there is a bug for this error

however it's supposed to be fixed in our curent version

do you know any SFTP servers that will allow me to modify the parameters stated on the bug ?

freeftp is not an option

solawinds (free version) doesn't work quite well

I'really appreciate your help

Modify the SSHTimeout to 1200

This server works perfecto but you have to modify the SSHTimeout to 1200 at least, else youl get this error:

/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 ...

UCM Backup

Try to see this in Disater Recovery System Admin Guide

System Requirements

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

Cygwin (refer to
