BARS: Could not build archive successfully

Hi, I am using a DAT DDS4 tape drive in a HP DL380G4 CallManager server (As specified by Cisco), but the BARS backup fails to complete to the tape drive. Backups to a network drive are OK, as is a local drive. Windows detects the tape drive OK. BARS log file attached.

Any idea's?

Thanks in advance,

There is a bug that you might be hitting:

CSCsd25578: BARS failing to backup on tape media


1. Use Local or remote location for backups instead tape.

2. If required to use tape, ignore the message "Could not build archive successfully" and open the windows task manager and under the processes tab, check "Tar.exe" running. Wait for to get it completed. Backup will be created successfully on tape as well.

FYI, tar is successfully getting created on tape. It is only progress bar error which gives this wrong status due to 'overflow' error. AND user has to wait till tar completes its operation on tape (given in workaround). "Could not build archive successfully.", this message can be ignored for the time being for the tape backups.
