I am getting occasional failures of a SQL Server 7.0 complete backup to disk on a production database. The errors seem to indicate that another process has the disk file open at the time of the backup. The errors contain the following texts : -
'Cannot open backup device'
'Operating System Error=32 Process cannot access file because it is being used by another process'.
The only other process that should access the disk file is an ARCserveIT scheduled job to copy the disk backup to tape but this is completing long before.
In SQL Server 2005, via the GUI, I wish to backup a database to an additional disk file (there is already an existing backup disk file for this database), so that I can have more than one backup. I've added the new disk file name, highlighted it, and clicked OK.
I get an immediate error (see below). Note, the 2nd error message is specifying the existing backup disk file, not the new one I'm attempting to create.
"Backup failed for Server 'WCS-DEV-TPA'. (Microsoft.SqlServer.Smo)"
"System.Data.SqlClient.SqlError: The volume on device 'D:Program FilesMicrosoft SQL ServerMSSQLBACKUPWCS_ADV_Longmont.bak' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set. (Microsoft.SqlServer.Smo)"
Does anyone know what causes this and how to correct it?
We have a job created by the maintenance job wizard that backs up the transaction logs for all of our databases on an hourly basis. At random intervals, one of the tranaction log backups will fail with the following message in the job history: sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed.
The next scheduled transaction log backup will run fine the next hour. The sqlmaint.exe is present and executable. There are no additional messages in the SQL Server error log or SQL Agent error log. Any ideas what causes this random failure?
Is there any benefit in creating a backup device and using that in the backup statement over just using a disk file in the backup statement. It seems like extra work to create the backup device with sp_addumpdevice with the file location. Whereas I could just specify the file location right in the BACKUP statement by specifying DISK as the backup device.
In SQL 2000, is there an advantage to defining and using a backupdevice versus just backing up to disk?Currently, I've got a SQL Backup job set to run once per day, withtransaction log backups running every hour. The db and backups arewritten directly to folders on an external disk array. I've neverconfigured an actual Backup Device within SQL. Does creating a BackupDevice offer any advantages not available with my current backupmethod?Thank you for any help.Jason
If databases on a physical drive [G:] are fragmented, and the drive isextended by adding more hard drives to the array, does it make sense tobackup and restore the fragmented databases?The Windows Server should be able to find contiguous space for eachdatabase, since it shows 75% free space on the SQL Data drive withoutany file fragments on it.Or will it restore to the original location, in which case does it makesense to delete the databases and restore them from the backups?Thank you very much!
Hello, SQL 2000 backup to C dirve fails with event 17055 Operating system error = 5 access is denied. Creating and running a backup job wizards errors with SQL State 42000, Deveice error or device off line. SQL is running as LocalSystem. The backup destination has every Windows group added with Full Control. Thanks
We get frequent (1 out of 3) "sqlmaint.exe failed" errors during backups for one of our larger databases (40GB). So i removed the maintenance plan and put in a custom backup job to get a better error msg in the log:
BackupMedium::ReportIoError: write failure on backup device 'F:MSSQLmydb_2008_1_3_21_45.BAK'. Operating system error 112(There is not enough space on the disk.).
However, we have PLENTY of space on disk: LOG DISK - NTFS - used space = 2GB, free space = 81GB BACKUP DISK - NTFS - used space = 29GB, free space = 82GB So even if it doubled in size, there would still be 50GB free.
hello,all I am new to Sql 2000,I installed sql 2000 database in C disk,but Now I found my C disk space is smaller than before,So I want to move my databse(include data and structure) from C Disk to D Disk(its space is very large) . is it possible to do it ? if its can be done ,do I need to change my asp.net program source code (exp: chaneg my crystal report connectstring ) ? thanks in advanced!
What is the percentage of FREE disk space that is needed for a backup? I have backups that are failing with no disk space errors. But there is enough disk. Does SQL Server need a percentage of free space all the time?
When I select All Actions>Backup Database and then click the ... button to choose a location on the hard drive, SQL Enterprise Manager Hangs and I have to kill it from Task Manager.
All other areas of EM browse the disk drive without a problem. (DTS, File Groups, etc.)
I am trying to create a scheduled task taht will restore a database from a backup file. I do not store my backups on a backup device, but on a local disk. To restore a DB from a backup device, the following statement will work: "Load DBName from BackupDeviceName". Does any know what statement to use to restore from a file, if the file is "E:DBName_db_dump_199909272220".
One of the drives that stores the database file is close to running out of space. The chance of me getting more space added to this drive any time soon are really low. What are other options I have?

Hi all, I have to give support to this new client of ours and the system out there was a real mess.The log files for all four databases were ranging from 5 to 9 GB's, no maintanance no nothing was done since the setup of the system. I have truncated the logs after taking proper backups since it all started after they compalined a DTS was not working, which was due to no disk space available ;). Now I have to shift the log files to a seperate disk. I know it can be done by detaching the database and attaching it back, I was wondering if we can do it without bringing the system offline? Anycomments welcome. Thankyou. regards, harshal.
Due to running out of disk space and reducing I/O contention, I plan to seperate data files and log files to different disk arrays.
My plan is to - detach all databases - copy log files to another disk - attach all databases
The total size of log files is about 60GB. It becomes a problem becasue it spend too much time passing files. To reduce down time, is there any way I can do?
Can I just create new log files and remove the current files by using sql management studio?
Hi, I'm trying to write a restore script. In the past I've always used the SSMS GUI to restore. When running the script below, the process got stuck at around 90%. Eventually I aborted the restore and found out that my C drive was full. The log file of the database I was restoring was 32GB. Can anyone tell me what I'm doing wrong? Thanks.
Code Snippet ALTER DATABASE [oms] SET SINGLE_USER WITH ROLLBACK IMMEDIATE GO

I have run perfmon and the avg read queue length is pretty much permanently maxed out at 100%.
I have run a database index defrag.
On further inspection the file system is highly fragmented. There is a file fragmentation of 98% with the mdf file fragmented in 25,000 pieces. Running a standard windows defrag does not resolve this.
Two questions?
1- Is heavy file fragmentation of the MDF file a likely cause of the read queue length bottlneck?
2 - Why is the MDF file not defragmenting? Does the SQL server have to be taken offline? Is it possible to defrag a MDF file?
Our MSSQL 2000 server crashed yesterday and one database cannot be restored. the latest backup we have is june. We can only recover the MDF file from the harddisk and according to our admin, it cannot be restored anymore because no proper shutdown was made.
My Transactional log size increased to 39GB, it is in full recovery mode,
To regain the space, i have done the following BACKUP LOG DB_NAME WITH TRUNCATE_ONLY DBCC SHRINK_FILE (LOG_FILE_NAME,500) But not able to regain the space in the hard disk.
No Transactional backups to truncate the log file were setup.
Can you please tell me why the space was released and what should i do further to clean up the sapce
If I return the Average, Minimum, and Maximum values for the counter Physical Disk: Avg. Disk Queue Length, and those values are 10, 0, 87 respectively, which value do I use to compute the Avg. Disk Queue Length for a 4 disk array(RAID 10): Average, Minimum, or Maximum? The disk(lun) is on a SAN.
Using SQL Server 2005 Server Management Studio, I attempted to back up a database, and received this error:

I am fairly new to SQL 2005. Can someone help me get past this issue? What other information do I need to provide?
