DB Maintenance Plan

Hi Gurus,
I am getting an error while the backup plan is getting executed. Until last
week it is fine working perfectly. Nothing has been changed as far as the se
ttings are concerned. The job is run every night. It is being executed as a
domain user (domain\adminis
trator) and the backup is being written to the network mapped drive (\\ipadd
ress\<driveletter>\Backups\<servername>\<dbname.bak> ).
Whenever it is failed, the status is being shown as 64, see the SQL Server e
rror log for details. [SQLState 42000] (Erorr 3202) Backup database is t
erminating abnormally. [SQLState 42000] (Error 3013). The step failed.
The statement being used is
Backup Database <dbname> to Disk = '\\ipaddress\<driveletter>\Backups\<serve
rname>\<dbname.bak>' With Format
Other details are as follows:
BackupMedium::ReportIoError: read failure on backup device '\\ipaddress\<dri
veletter>\Backups\<servername>\<dbname_log.bak>'. Operating system error 64(
The specified network name is no longer available.).
BACKUP failed to complete the command BACKUP DATABASE REPL TO DISK = '\\ipad
dress\<driveletter>\Backups\<servername>\<dbname.bak>' WITH FORMAT
Internal I/O request 0x2B97F408: Op: Read, pBuffer: 0x00000000, Size: 52, Po
sition: 12884901921, RetryCount: 8454144, SubIoCount: 2, UMS: Internal: 0x2,

Any guidance will be highly appreciated as i am trying to find a solution fo
r a long time.
Thanks in advance.This looks like a network or file system error. Try to determine if it
fails all of the time or some of the time. Does the failure relate to the
size of the database backup. or the space available on the hard drive...
It is not a good idea to use mapped drive letters, because that could change
if someone else logs on to the system...Perhaps that is happening..
Change the backup to use a UNC name ie
backup database prod to disk = '\\server\share\dbname.bak' with format
and see if that makes any difference..
Also check the event logs ( and check with network folks) to see if there
have been any funny network things happening lately.

Thanks for the reply. The failure is happening from time to time. I don't th
ink that the failure is related to the database size, because previously the
backup is going on fine.
I will get back to you as soon as some more information is captured at my en
d to post the same over here.
Thanks once again.
