I'm having trouble backing up my CUCM8.6 environment.  I receive an error on the CDR_CAR feature within DRS.  All of the other components like CCMPREFS, CCMDB, PLATFORM, CLM, etc get backed up successfully.

I am backing up to to a file server running SilverSHielD SFTP software version 6.0.28.128.  I tried version 5 of SilverSHielD and had the same results.

I attached the log file.  Perhaps somone can figure out what it says and point me in the right direction.

I verified our SFTP server has enough hard drive space.  It has over 40GB available.

NOTE:  I have had previous success using this backup configuration for a long time.  It wasn't until recently that I started noticing the errors.
