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.
View 1 RepliesIn 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
View 1 Replies View RelatedThis is probably a simple question but I have to ask it anyway. When backing up I can backup to a file on my local drive but I also can create a device to the same location on my local drive. Is this doing the same thing. If I so desire to backup to the local drive(bear with me) what is the difference between creating a device and a file called mybackup or just choosing to backup to a file called mybackup? Should I always create a device? I know these are dumb question but....

How do we know the list of all the backups that are present in a particualr backup device like file# and time of backup taken etc for the purose of restore?
When I run :
RESTORE HEADERONLY FROM BackupDeviceName
it doesn't give that info. Can anyone tell me the exact command to list all the files of a backup device so that I can restore the right one??
Thanks.
Shalini.
I dump my databases to backup devices each night.
However would like to purge old backups - say older than a week - from the device.
Is it a case that I have to drop and re-create the devices every 7 days or can SQL do this for me?
I have seen the RETAINDAYS claus but it applies to tape backups only?
Thanks
Hi all,
I want to store bakup file on the computer on netword, so make a backup device on the other computer, it ok. after that i make an full backup, there is an error : "Can not open the bakup device " .
please show me,
best regard.
Hi
is there a stored procedure which allows me to query if there is an existing backup device? or which gives me a listing of existing backup devices?
Thanks!
Hi,
request you all to clear mine one doubt that,
Can creating a backup device for sql backup reduce the backup time comparing to giving full backup path.
Cheers!!
I have a transaction log which is backed up 5 times a day to a device.
The Transaction log is growing quite quickly in between each backup. The backup device is also growing at a much quicker rate.
realistically i would like to only keep 2 weeks worth of transaction log backups in the device.
for the transaction log backup i have tried the following transact-Sql
'Backup Log [imsv23] to [imsv23_TL_2] with RetainDays = 7, Init, NoUnload, Name = N'imsv23 TL V2', NoSkip,Stats=10,Noformat'
but due to all of the contents in the backup set not having expired the backup fails.
i need to reduce the size of the backup device. all of the backup sets have expiry dates but none of them are being deleted from device.
so my problem is 1 i need to remove the excessive backups from the device
2 i need to set up the automatic backups so that these datasets are removed when the expiry date is reached.
thanks in advance
If it can, is there some special way to set it up? I can only be successful setting up a tape drive.
Thanks,

Hi Folks,
I have a SQL Server 7.0 with and exteranl SCSI tape device.
When I attempt to backup a database in EM the tape device is being greyed out.
I have add the backup device using sp_dumpdevice and made sure that it is in sysdevices table. It will not allow me to add this backup device from the drop down.
1. Why does EM not see this device ?
2. If I try to back this up using T-SQL will I be able to use the registared tape device.
Thanks Folks
I'm trying to set a backup job to back up my databases to a server other than the server where Sql server is installed. The only options I can see are the local drives on my sql server when I try to set a location or backup device. If I want my backups to go to another server , How do I do that. Currently I'm trying to use a UNC path like \ServerNameBackups. When I try to use a UNC path I get an invalid directory error.
I'm fairly new to SQL Server as you can tell!
Can anyone help me? (I'm using sql server 2000)
Thanks

I am a newbie in SQL Server Administration. I decided to make the move within my company that no one else wanted.
I have SQL Server 2000 running at this time; users are connecting and using it. My question I guess pertains to the backups.
I have two drives setup for data and transactions logs (D: E:)
My backups are running but backups are being sent to the d:systems datamssqlackup folder. once backups are comlete I normally copy the backups to a network share that is being backed up nightly to tape.
My question is this:
How do i create a device location under backup properties to point to a network share? i would like for the backups to go straight to a network drive so i do not have to copy the backups every morning when i come in.
I want to be able to take a backup device to another server and then restore the last backup file within the device.
My script creates the backup device using the filename of the file from the other server but when I do the restore it only restores the first file in the device.
How can I get it to restore the last file? In EA I can do a manual resotre and look inside the device and choose say backup number 2.
How can I do this in a script?
Thanks
Hi,
I was wondering if someone could help me. I'm having problems using backup in Enterprise Manager, the backup continually fails and points to a hardware problem. However, I have been able to backup files using different software to tape which rules out hardware.
I'm trying to create a new backup device incase the problem lies there but I receive the error 'error15061: Add device request denied. A physical device named '%s' already exists'
Any ideas?
Cheers
I want to create a backup device for the tape drive.
So I go in "Server Objects"=>"Backup Devices" and create a new device. Problem is: In "Destination" I can't select "Tape:".
The ntbackup.exe program recognizes the tape drive, but SQL2005 not.
I have this:
-SQL2005 Enterprise edition 64bit.
-Tape drive HP StorageWorks Ultrium 960.
Someone knows how I can create a backupdevice for the tape?
Thanks

hi all!
appending new backup on a same device - yes or no?
if somebody can tell me, is ok to constantly create new backus on a same device? i'm asking that, because in that case, defice file it will grow and grow.
is there any limit or suggestions how many appending is recomended, cause of file growth?
tnx in adv!
I an trying to figure out a workable backup plan. I'd like to use a backup device, but I don't see how to keep a set number of days backups in it. Backing up to a backup device adds the backup in. How do I purge the expired backups so there is only, lets say, 3 days worth of backups in the backup device?
I've got a new HP ML370 G4 Server 2003 SP1 with a fresh install of SQL 2005 SP1. I'm trying to create a backup device for the internal HP DAT 40 and tape is greyed out as an option. I have the newest HP software drivers and firmware. The tape drive is seen by Server 2003 device manager and by NTBACKUP. I can backup using that program. Why doesn't SQL 2005 see it? I tried a new HP Ultrium tape drive with the same results. Anyone else see this and can recommend a fix? TIA
View 11 Replies View RelatedHello,
I am trying to configure the backup device on SQL Server 2005.
I cannot get the Tape device list.
The Tape Device is attached physicaly to the server ! (IBM Ultrium-TD3 scsi). I can 'see' the device using Windows Backup; but I cannot even get the list of tapes on SQL Server.
Can you please give me some help on this one ?!
Thank you all.

When performing a backup I'm reciving the error message: "System.Data.SqlClient.SqlError: Cannot open backup device. Operating system error 5(error not found). (Microsoft.SqlServre.Smo)
This is backing up to a network location and I'm able to backup other database on the same server/instance without error so it shouldnt be a permissions issue?why I can backup some databases to this location and not others?
I created a backup device and a job to backup a full dbs and transaction logs. When I first created the backup statement it was created with RETAIN DAYS = 10
Its been 15 days and the ones created after 10 days appear to be marked for deletiong but I am obviously missing a statement in my backup statement or in another job I need to schedule to come through and delete the old files from the backup device. Please help me figure out what this statement needs to be.
All the backups and T-log backups are written to one device which is one file.
Thanks

Is there a way to initialize a backup device without actually backing anything up to it?
This would make my backup code much simpler.
hi gurus,
can any bdy tell me the procedure to create the Backup Device which is a DISK OF REMOTE PC..
i want to take database backup on remote pc's disk not on local disk or tape
i am using sql server 2005
thanks
in advance
Can someone help me with this error? It only occurs when I try to backup to
the UNC name (which is local to the machine). When I do it with a drive
letter, I have no problem.
Thank you
Hello,
Every hour I make a backup of the log files of a database to a backup device. Each backup is appended to this backup device.
Now to restore at a point in time I normally use the following script;
RESTORE DATABASE mcs_carolus
FROM disk='E:sqlserver_databasesmcs_carolus_data.bak'
WITH REPLACE,
NORECOVERY
go
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 1, NORECOVERY
GO
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 2, NORECOVERY
GO
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 3, NORECOVERY
GO
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 4, NORECOVERY
GO
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 5, NORECOVERY
GO
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 6, NORECOVERY
GO
RESTORE LOG MCS_CAROLUS
FROM disk='E:sqlserver_databasesmcs_carolus_log.bak'
WITH FILE = 7, RECOVERY,STOPAT = 'Nov 25, 2004 11:59 AM'
Is there a simpler way of restoring without going through this long process.

Albert
Does anyone know if it is possible to have a tape device another server as a tape dump device on SQL. Instead on removing the tape drive and installing it locally ?!?

Hello:
We have, on a devlopment server, running a long_running transaction for
almost two days. It was still running. This morning I decided to look at
three of two backup devices under EM to see if any backups were made to
these devices during the last couple of days on a de,mand basis by anyone.
The first one had a backup and the second and third device did not.
Somehow, and for some unexplained reason, the following message was put
into the MSSQL error log (and pretty much the same message went into the NT
event viewer).
----------------------------------------------------------------------
99/02/23 10:05:45.81 kernel dbsvolopen: Backup device
'E:MSSQLBACKUPEaglePro2_run02.DAT' failed to open, operating system
error = 2(The system cannot find the file specified.)
99/02/23 10:05:48.48 kernel dbsvolopen: Backup device

99/02/23 10:05:49.17 kernel dbsvolopen: Backup device
'E:MSSQLBACKUPEaglePro2_run03.DAT' failed to open, operating system
error = 2(The system cannot find the file specified.)

This error, I beleive, caused DR watson to kick off and we could only sopt
it and revive the long running transaction by rebooting the machine, of
course thus requiring us to restart the lon_running transaction.
It look like NT couldn't find the backup device and therefore activated the
drwatson executible or so it seems to me.
Has anyone experienced this error before? IS it caused by NT? Or that
perhaps a certain threshhold was reacched on NT and drwatson kicked in?Any
other ideas?
Any information that can be provided would be GREATLY appreciated. THanks.

I want to set up remote backup device on "serverCentral" for 50 MSDE SQL2k servers so that they could use one backup to create(restore) any new customer databases. This way, I could keep one resource with many coming updating on procs and triggers...
I could create remote backup device with serverCentralackupackupdeviceName...
The problem is the remote device is "access denied" when I issued a "restore headeronly from backupDeviceName" sql query.
Neither I could issue xp_cmdshell 'dir serverCentralackup' --"Access Denied" from server49
Though I could dir serverCentralackup*.* from server49 command prompt.
It looks security permission is OK otherwise I could not dir from command line.
thanks for the help

I ran into a problem today where I had to pull a backup file from an older tape. The file was originally is a backup that was stored in a device like :
EXEC sp_addumpdevice
'disk', --type
'c2000_BackupDevice', --logical name
'\UNCPathackupFile.bak' --physical location
I put the file from the tape on a File Server and then tried to create a new backup device pointing to the file. That's easy enough, but when I try to restore from it I get an device error saying it's offline.
How can I get that device attached to my server and then extract the backup files stored inside it?
Please advise b/c this is an interesting problem I hadn't anticipated and it argues that I should change my backup strategy .
Thanks for any advice/experience you can provide,
