You can take database snapshots at different times.
BOL: "A database snapshot is a read-only, static view of a SQL Server database (the
source database). The database snapshot is transactionally consistent with the source database as of the moment of the snapshot's creation. A database snapshot always resides on the same server instance as its source database. As the source database
is updated, the database snapshot is updated. Therefore, the longer a database snapshot exists, the more likely it is to use up its available disk space.
Multiple snapshots can exist on a given source database. Each database snapshot persists until it is explicitly dropped by the database owner."

SQL Server 2008 & 2012 Database backup on a shared loaction
Hi,
I have to plan for the Database backup on SQL Server 2008 & 2012 on a shared Path.
We are building a new Maintenance plan & specify the Database which needs to be backup & at the Folder location we specify the Shared Path Location. These steps I have followed using the below link,
http://social.msdn.microsoft.com/Forums/en-US/be138ca3-4b2f-4464-8115-9a0a6f2e0fe6/sql-database-backup-on-network-share-using-maintenance-plan?forum=sqldatabasemirroring
But the operation fails & throws the below error:

Purvish ShahHello,
>>'\\DBBackup\SharePoint_backup\DB_backup_2014_02_13_122719_5314660.bak'. Operating system error 5(Access is denied.).
This clearly points out to fact that your SQL Server service account does not have permission of read/write on shared location,simple.
>>But when I open the shared path in the Windows Explorer it opens successfully.
This is because when you are browsing through explorer your windows login credential is used to access that folder but when you are running backup your SQL Server service account permission is used to write backup on shared folder ( which I assume it does
not have ) so the access denied error.
Hope this helps
PS: I reffered the link its maily how you specify backup path its not about access denied error due to SQL server service acount not having privilege

Hi,
One of our client is taking the SAP SQL database backup using BRTOOL, backup happen on Standalone LTO 5.
They are taking backup of 1.4 TB in 1hr 30 Min.
I would like to know is it possible to achieve same as max write speed of LTO 5 in 140 MBPS, if we consider the are getting max throughput rate then too it should take around 3 hr 40 Min.
If it is possible then it would be grateful if someone can explain how.
Thanks & Regards
Mitt GoriHi Mitt,
You may refer the details shared under thread Full Database Backup in DB13 for MS SQL Server ... | SCN on configuration of backups using db13 for MSSQL.
What it comes to my mind is ..
1) Can you check whether you have SSDs configured for the database
2) What is the Tape write speed.
Note: SSD disks can drastically improve the backup times as it has excellent read/write performance over SAS disk.
Hope this helps.

PREEMPTIVE_OS_GETPROCADDRESS SQL database restoration hangs
Hi,
We are using SQL Server 2008 R2 SP1 in our production environment and Litespeed tool for SQL database backup.
Today we are facing an issue in database restoration. while the database restore is 100% done, it hungs and the database in the restoring status itself. We checked the wait-type and found out "PREEMPTIVE_OS_GETPROCADDRESS" for Query type xp_restore_database.
It was working fine till yesterday and today suddenly we got this error. We restarted the restore job and again we are facing the same issue.
Can you please help on this.Hello,
Try the workaround posted on the following resource:

Database backup file size is too small compare to actual database size
Hi All,
I know that backup file size can be smaller than actual DB size (i.e., MDF size + LDF size). But in my case i am observing huge difference.
My Database size is 16 GB out of which 10 GB consumed by MDF and 6 GB consumed by LDF. But when i took the backup, the backup file size is only 1 GB!!!!!
I am skeptical about whether i am doing anything wrong. Please advice me.Olaf is right it must be compressed backup:
To check if the backup file is compressed or not
RESTORE HEADERONLY FROM DISK = 'Path to backup file';
Looks for column labelled "Compressed". 1 = compressed, 0 = not compressed.
If you are skeptical about backup file you can verfiy whether a SQL database backup can be read and restored:
RESTORE VERIFYONLY FROM DISK = 'Path to backup file'
If the backup is valid, the SQL Server Database Engine returns:
The backup set on file 1 is valid -
Offline Backup in SQL Database using DB13
Hi experts,
I am new to MSSQL database.
We are using ECC 6 with MSSQL 2005. In DB13 we get the following options.
Full Database backup
Diff DB backup
Transaction Log Backup
Check DB consistency
We do not have the option to take a offline backup from DB13.
My question is, weather it is possible to take a offline backup in MSSQL.
If yes could please give me the procedure for doing a offline backup using DB13.
Thanks in advance for the response.
Regards
AnilLol, No by definition SAP and SQL would need to be down to take that type of file backup.
Offline backups are not a supported recovery method.
Online backups will allow for PIT or full recovery.
Offline backups will not be report in SQL or SAP as you haven't backup the database - rather just the files. -
I have a SQL 2008 R2 database that I am trying to move to 2012. Made a full backup of the database in 2008 R2. Recovery model is Simple, compatibility level is 2008 Went to 2012, created a dummy database, did Tasks--> Restore -->
Database , located the backup file, selected it, changed the file locations and tried to restore the backup (with overwrite option), got the following error:
BACKUP LOG cannot be performed because there is no current database backup.
This is a simple task that has always worked in 2008 R2. Does anyone know what the problem is and a possible solution?
ThanksHi,
This error occurs when the database recovery model has been changed to Simple and/or the recovery model has been changed back to Full but a full backup has not been performed since the change.
If a full backup has been performed, the following conditions will require that another full backup be taken:
· The recovery model had been changed without taking a full backup
· A SQL maintenance plan task had changed the recovery model (reindexing can cause this)
· A backup specifying TRUNCATE_ONLY had been run on the database
· The database was detached from another server and attached to the current server
Additionally, if we take full database backup after the Database is set to readonly, Then transaction log backup we will end up with this error. This is expected behavior. I have list an example within the link below.
Please check above conditions and fix your issue, if you have any concern, please let me know.
Example:
BACKUP LOG cannot be performed because there is no current database backup.

T-SQL: Manual Backup of Multiple Databases
I am looking to change the way I do manual backups of multiple databases on the same instance of SQL Server 2008 R2.
Currently I have T-SQL scripts for each database that look like this:
BACKUP DATABASE [mydbname]
TO DISK = N'D:\backup\manual\2014-01-01_1618\mydbname_2014-1-01_1618.bak'
WITH NOFORMAT,
NOINIT,
NAME = N'mydbname-Full Database Backup',
SKIP,
NOREWIND,
NOUNLOAD,
STATS = 10
GO
But there are six of these scripts, one for each database. Now in another language and my past programming experience I would just use an array of database names and a loop, so that BACKUP DATABASE would only exist once in the script, but be executed multiple
times, once for each database name in the array.
I have such a very limited understanding of T-SQL, but I am guessing there is a completely different paradigm for the equivalent of, say, a for loop.
I'd also like a solution where the date_time directory for the output of each backup to be dynamically generated. Instead of having to pre-create the dirs myself.
Any help would be appreciated.I don't understand why you haven't been answered directly considering the simplicity of the question you are asking. Maybe it's because I'm the only truly "old school" DBA left. I don't use the GUI based maintenance or performance tools included
with SQL Server not because I'm "old school" but because every time I've tried the results have been mediocre at best and in an environment where critical data is on the line mediocre doesn't cut it.
Since I've had this type of tool in my "tool box" for more than a decade allow me to share what I typically do in this type of situation...
declare @DatabaseName nvarchar(50),
@DynamicSQL nvarchar(4000),
@FileNameDate nvarchar(18)
declare Database_Cursor
cursor fast_forward for
select d.name
from sys.databases as d
where d.name in ('MyDB1', 'MyDB2', 'MyDB3', 'MyDB4', 'MyDB5', 'MyDB6')
open Database_Cursor
fetch next
from Database_Cursor
into @DatabaseName
while @@fetch_status = 0
begin
set @FileNameDate = cast(year(getdate()) as varchar(4)) + '-' +
right('00' + cast(month(getdate()) as varchar(2)), 2) + '-' +
right('00' + cast(day(getdate()) as varchar(2)), 2) + '_' +
right('00' + cast(datepart(hour, getdate()) as varchar(2)), 2) +
right('00' + cast(datepart(minute, getdate()) as varchar(2)), 2)
set @DynamicSQL = '
BACKUP DATABASE ' + quotename(@DatabaseName) + '
TO DISK = N''D:\backup\manual\' + @FileNameDate + '\' + @DatabaseName + '_' + @FileNameDate + '.bak''
WITH NOFORMAT,
NOINIT,
NAME = N''' + @DatabaseName + '-Full Database Backup'',
SKIP,
NOREWIND,
NOUNLOAD,
STATS = 10'
print @DynamicSQL
--execute sp_executesql
-- @DynamicSQL
fetch next
from Database_Cursor
into @DatabaseName
end
close Database_Cursor
deallocate Database_Cursor
There are two items you need to change in the above script to make it do precisely what you are asking...
This should be obvious but you need to change the where clause in the cursor definition to include the 6 databases you want o backup instead of leaving it as "where d.name in ('MyDB1', 'MyDB2', 'MyDB3', 'MyDB4', 'MyDB5', 'MyDB6')"
I've commented out two lines of code in the script. Those lines actually run the backup statements which are built by the cursor. The lines I'm referring to begin with the "execute sp_executesql" statement. I've commented those lines out
because you'll need to test the code prior to using it. The code as designed will output the backup statements it procedures allowing you to verify it.
I hope that helps. -
Query used by SQL Server Management Pack for monitoring database backups
I use SCOM 2012 R2 and the SQL Server Management Pack to monitor SQL Server database backups. I believe I am getting false positives. SCOM reports database are not backuped, while in fact they are. So I need to troubleshoot this. I suspect SCOM is querying
the backup history in the msdb database. I want to know which query SCOM uses.
I have tried looking in the monitor's definition but I suspect the query is embedded in the management pack files which are binary. I have also tried running a trace using the SQL Server Profiler on my test environment and overriding the interval to 60 seconds,
but I don't see a relevant query being executed. I also don't see the alert reappear so I suspect SCOM does not honor the interval in a way I would expect.
What query, or other method, does SCOM use to check database backups?
Thanks in advance.Thank you both Ivan and Michael,
I only saw your messages by email and didn't see your screen shot before I extracted the query myself. In my own queries I calculate the backup age in hours instead of days because of daily full backups. Perhaps It will be a good idea to create my own monitors
from scratch like I used to do with Nagios.
I will study the vbscripts and might create my own version which allows the query to be entered as an parameter and move all code to a .Net class which can be called from vbscript as an COM object. This way I hope to reduce the vbscript code to an minimum
while keeping the flexibility of the SCOM Operations Console and the robustness of .Net. I suspect I want to make more non standard monitors in the future.

Full Database Backup in DB13 for MS SQL Server databases
Hello,
We have some SAP systems using the MS SQL Server database. I want to know if it is possible to setup the Full Database Backup option in transaction DB13 to store the files in a hard disk space.
I already did this type of configuration in SAP systems in Oracle databases and for this I used the init<SID>.sap where we can put all the configuration, for instance the disk path where we want to save the backup files! But for MS SQL Server databases, in DB13, I don´t know how to do that, when I add the "Full Database Backup" option in DB13, this show me some options but only for tape, but I don´t want to store the backup files in tapes, I want to store/save the files on the server disk itself or else to an external disk but I don´t see where I can set this way of storage!
This is what you see in DB13 (when using a MS SQL Server database) in "Full Database Backup" and as you see I only have options for TAPE not for a disk or other type of storage! How can I do that? (if that is possible):
Can you help me please?
Kind regards,
samid raifHello Raja
Sorry for the delay of my answer! Many thanks for that tip, it helps a lot and it solve the last error/problem that I reported here, in fact, the problem was we had named the device with two words containing a space. So we removed that space from the backup device (in SQL management studio) with one word only and the job runs successfully without any errors!
It works in Development and Quality systems but in our Production system (AM1) the Full backup option in DB13 stopped with the following error, in fact the error is on verification of backup, it means that the Full backup finished with success, but when it does the backup verification, the job in DB13 stops with an error, the following one:

Restoring an ms access database backup file in sql server 2005
Hello everyone.
I have an ms access database backup file.
Presently i dont have ms access database in my system.
It is high priority to access that ms access database backup file.
So, is there anyway to access that in sql server?
-- Thanks and Regards Srikar Reddy Gondesi, Trainee SQL Server Database Administrator Miracle Software systems, Inc.Hello sir,
i tried to use import/export wizard to import data from an ms access backup file.
I completed it with some warning's.
Wizard has shown that 2 out of three objects(tables and views) are copied to destination database(empty database which i have created for storing this imported data).
And in that process, wizard made me to create a package.
Now how to access that package?
And my newly created database has no data.(i mean it is supposed to have 2 objects which are copied from source right?)
Sorry if my doubt looks silly i have never used ssis or import/export ever before.

Hi Team ,
I have SQL Cluster 2012 server running with Couple of Critical data base instance . Each instance installed in different drive.
One of my application database is having mdf of size 1 Gb and ldf is 250 GB . Database is set to full recovery model.
Now I want to change recovery model to simple and want to shrink the los also. before than I want to take database backup.
I have 50 GB space left in drive .
i want to take full database backup on same drive .please let me know how much space i need on that drive to take full backup.
thanks
RaviThere are two options for you here
1. Take transaction log backup and try shrinking the log file but you might have to take multiple transaction log backups to actually shrink the log file
2. If you are switching from full recovery to simple you dont need to take full backup reason is switching from full to simple breaks log chain so its better to have Transaction log backup and like Praveen suggested if you take transaction log backup with
compression it likely it would fit in free space. But you have to try.
3. This you have to do on your own risk: (If backup of log in point 2 fails) I dont think changing from full recovery to simple would cause any
data loss. So you can switch to simple shrink logs switch back to full and schedule frequent log backups
Reason why log grew so much because you did not took sufficient transaction log backups. So create maintenance plan which would take frequent log backups also if you dont want point in time recovery for this database let it be in simple recovery
