Backup Failure - Operating system error 64

I am receiving the below error message while doing a Database backup as a
schedule dts package job.
Operating system error 64(The specified network name is no longer available.
).
or
Operating system error 64(error not found).
18210 :
BackupDiskFile::RequestDurableMedia: failure on backup device '
\\SERVER_NAME\SQLBackup\Production\Datab
aseName.bak'. Operating system error
64(error not found).
18210 :
BackupMedium::ReportIoError: write failure on backup device
'\\\SERVER_NAME\SQLBackup\Production\Dat
abaseName.bak'. Operating system
error 64(error not found).
Please note, I am backing up to a networked drive/location using the below
command as an example, which is not a mapped drive,
BACKUP DATABASE [DatabaseName] TO DISK =
\\SERVER_NAME\SQLBackup\Production\Datab
aseName.bak' WITH INIT
The same scheduled dts package backup job sometimes run successfully at
the scheduled time and most times failed. The job is ran under the SQL Serve
r
Agent account which has full access permission to the backup network drive.
The backup dts package always run successfully when ran manually using my
login account.
Thank you and kind regards
MichaelMichael,
The OS error 64 usually indicates the network problems.
Intermittent loss of connectivity to the share. To ensure that the
backups for the database are taken properly, I recommend you backup to
the local drive and then create a NT job to move the job to the share
upon completion of the SQL Backup. If the Nt copy job fails, then we
can be sure that the problem is because of network connectivity.
Hope that helps.
