Error in backup process.

Hi everybody,

I'm trying to backup a database of 330 GB more or less from my server to an external hard disk connected by optical fiber and I'm receiving the next error:

[SQLSTATE 01000] (Message 3211) Write on "H:\sqlbackup\pm_import" failed: 33(The process cannot access the file because another process has locked a portion of the file.) [SQLSTATE 42000] (Error 3202) BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.

Any idea?

Thanks!

refer this link,

http://msdn2.microsoft.com/en-us/library/ms837537.aspx is there any other process that is accessing your db just type sp_who2 and see if anything is accessing your db.......any operations going in your db other than backup any bulk insert etc?......

|||Absolutely nothing! I put the batabase in SINGLE_USER mode.

no need to bring to Single user mode . SQL Server has online backup architecture. The problem seems to be the Target file. ie the Backup file in H:\SQLBackup. check any process is using the file when u take backup. It need exclusive access to that file. to debug the issue... create a new database and take backup in the same path ie . H:\sqlbackup\test.bak or something like this. if u r getting same error then the problem may be something else. post back the result of this debug process i mentioned

Thank you very much Madhu. I thought the data file was locked by another process, but in fact it was the target file who was block by the anti-virus.

So problem solved!

Thanks again.
