Error Message:

E3712  Unable to close session. (EC=COMMAND ABORTED)
E3719  Unable to write to media. (MEDIA= [S/N: ],EC=COMMAND ABORTED)


Staging backup job to File System Device ( FSD) fails with the error mentioned above.


Enabled tape engine log in debug and ran backup again.

As per activity log :


E3712      Unable to close session. (EC=COMMAND ABORTED)
E3719       Unable to write to media. (MEDIA=10/23/13 8:45 PM [S/N: ],EC=COMMAND ABORTED)
From the Tape Log :
[02/27 07:21:36 3eb0  2 WD   485   486   4] FsdGetDeviceFreeSpace::Failed to query the free space of FSD device. [Path=G:\DailyBackups\Wednesday\, MS=21]
[02/27 07:21:36 3eb0  2 WD   485   486   4] RM_SCSIO::SCSI_WRITE::Failed to get the free space of FSD device [G:\DailyBackups\Wednesday\]. [MS=21]

Since the tape logs shows that there is not enough space available on disk to complete the backup job

1] Verify space on the drive where the FSD is configured and as it was less.

2] Suggest to free up some space on the disk and reduce the number of weeks to purge data.

    syntax format [driveletter:] /FS:NTFS /L does not work on Windows Server 2008 R2 SP1.
    Instead you can use format [driveletter:] /A:4096 /L /Q
