Hi,
I encounter problem when performing full backup. Anyone could help me on this?
BACKUP failed to complete the command BACKUP DATABASE

Is this everytime you run a full backup? How are you doing this (EM, code?)
could you have multiple backup jobs scheduled?

Hi Steven,
I did it from both, EM and Backup maintenance plan. Backup operation failed. Please advise.

The key may be the "Operating system error 33(The process cannot access the file because
another process has locked a portion of the file.)." message.
It would be worthwhile to check what else may be running, including stuff run by your Windows administrators.
On the DBA side, check if multiple jobs are trying to use the same file.
On the Window side, check if a tape archive is running at the same time as your backup. Also check for anything else that may do a similar lock, such as server imaging running. Also try to create another file in the same folder, or if your file already exists, try to delete it.
If you are sure nothing else is using your file but you cannot delete it, then there is almost certainly a Windows lock on the file. If nothing else clears the lock, reboot the box and try again.

If you see the URL below:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/system_error_codes.asp
It clearly mentions that this is a Lock_Violation error...Pls check what other processes have a lock on this file..try using some other file or as Ed said restart the box
Cheers!

Something else you might want to check, is to see if you have compression set on folder you are backing up to. I had a similar error recently where it would backup the database to 90% and then fail. Once we removed the compression option on the folder, the backup finished successfully. Check the properties of the folder and then the advanced button and make sure "compress contents to save disk space" is not checked.

I've had this problem with Backup Exec when Backup Exec was backing up the folder/file while the DB backup job was running. The solution was to coordinate the EM/Backup Exec backup times so they did not overlap.

A slightly OT comment on NTFS compression, at least on NT4...
If you copy a file over 2GB over the network to a NTFS compressed folder it is VERY flaky, failing with an error about incomplete writes many more times than it succeeds.
The really nasty bit is somtimes the failure leaves the NTFS MFT corrupt. You do not notice any problem until you next reboot, which can get as far as a blue screen, or may just hang. Either way, you have to rebuild the box.
