This error in the Backup and Restore System (BARS) backup log is generated because the AlternateFileLocationX in the ProcessConfig table had a paramValue of Null. For each AlternateFile location, there is a corresponding record in the ProcessConfig table in the Cisco CallManager database. The alternate file location row in the Structured Query Language (SQL) ProcessConfig table refers to the TFTP service parameters to specify alternate TFTP file locations. These records exist only if there is some value entered on the Cisco CallManager Admin interface. There should never be a record where paramname is alternateFilelocation1 and paramvalue is blank or Null. BARS ignores such records for backup. An attempt to back up files from alternate file locations would be done only if the location is not Null.
This problem is documented in Cisco bug ID CSCee20122.
