MS-SQL backup and restore with NovaBackup DataCenter can be divided into 4 steps

• Initial preparation on the MS-SQL system

• Preparation of MS-SQL backup jobs

• The backup

• The restore Each of these steps is described in one of the following chapters.

Overview


The initial task has to be done on the MS-SQL server system. It has to be done only one time, except for the case that databases are added to the MS-SQL server. Hiback must be installed in beforehand. The Hiback package contains a program called himsdb.exe. This program is able to query the MS-SQL server in order to retrieve basic information like DB names. This information is used to create DBA files in the Hiback\MS-SQL directory. These files are necessary to define how the DB can be accessed by Hiback in order to perform an online backup. There are 3 types of DBA files describing

DB full backup DB differential backup DB log backup

Login into the MS-SQL system as a user having access to the MS-SQL server. Open a DOS box (cmd.exe) and change into the Hiback\MS-SQL directory. Issue the command himsdb -m a

In case the SQL server name is a composition of Servername\Domainname, himsdb has to be called with the –s option: himsdb –s

Servername\Domainname –m a, where the names have to be substituted

accordingly. Here is an example output:

C:\hiback\MS-SQL>himsdb -m a

Initial Preparation on the MS-SQL System


The naming convention for the files is <BackupType>_<ServerName>_<DBName>.dba. The work on the MS-SQL server system is done. In the next chapters the usage of these files is explained.


The preparation of the MS-SQL backup jobs is done in the Central Management GUI (ixt_cman). Start the GUI and login as a user having appropriate permission to create jobs. Click Jobs and place the cursor in the job-list panel (right hand side). Right-click to open the actions

dropdown list. Choose New�Single Job�DBA.

Release the mouse, the job-definition window appears. Fill out the form, begin with jobname and choose the MS-SQL server nodename from the node list.

Preparation of MS-SQL Backup Jobs


On the right-hand side click Browse. A filetree showing the filesystem on the MS-SQL server system is shown. The + signs let you open a directory. Browse down to the Hiback\MS-SQL directory, where you can see the DBA files which have been created before. Choose the DBs as well as the backup type to be backed up:

Click OK when finished. Choose a media pool as 1

st media pool and save the job by clicking OK down

right. The new job appears in the job-list. To start it right away, mark the job, right-click to open the actions menu and release the mouse at Start.


The backup can be started interactively as shown in the chapter before or at defined times via the scheduler. To run a scheduled backup, a schedule has to be applied to the job. If you do not have a schedule yet, it must be defined. You can find a description of these actions in the Hiback ixT Operation Manual which is part of the documentation kit.

The Backup


Point-in-time recovery We are describing the case of a point in time recovery for one database. A point in time recovery means that a sequence of restores has to be performed beginning with the last FULL, continuing with the last DIFF and following LOG and ending with the last LOG restore. Last means the last backup before the point in time to recover. For each restore a separate restore DBA file must be created. The name is arbitrary, it will be handed to the GUI in the restore process. The creation of the DBA files has to be done on the MS-SQL server system locally. The procedure is to copy the respective DBA files for that database into the Hiback\job directory and to change the HI_OPTION entry in the DBA files. The entry contains syntax which is handed to the MS-SQL RESTORE DATABASE command. For the FULL, DIFF and all LOG DBA files except for the last the entry is

HI_OPTION=”NORECOVERY”

When the last LOG is to recover, the HI_OPTION of the LOG DBA file is changed to HI_OPTION=”RECOVERY, STOPAT = ‘AUG11, 2009 13:25:45 PM’ “

for example. Novastor offers a commandline tool called pitrestore. Pitrestore has to be started on the MS-SQL server system. It accepts 2 parameters: a database name and a date/time information. The date time information is the point-in-time to recover the MS-SQL DB. Here is an example call for the point-in-time recovery of the DB Test for the 23

rd of

Novemer 2009, 14:11:

C:\hiback>pitrestore test "23/11/2009 14:11"

The Restore Sequence will be:

Restore Full : 001258977715 = Mon Nov 23 13:01:55 2009

Restore Diff : 001258981490 = Mon Nov 23 14:04:50 2009

Restore Log : 001258981927 = Mon Nov 23 14:12:07 2009

The last Logbackup wants to STOPAT 'Nov 23, 2009 14:11: PM'

End of Program

Please start the restore/recovery by executing

c:\hiback\job\restore\test\test.cmd

Pitrestore has created the script c:\hiback\job\restore\test\test.cmd which contains the restore commands in the right order. It has prepared the according DBA files which will be used for the restores.

Cross Recovery A cross recovery can be performed on the original system to create a copy of a database (with different name) or to perform a cross system recovery onto another MS-SQL server system.

The Restore


A separate restore DBA file has to be created. The name is arbitrary, it will be handed to the GUI in the restore process. The creation of the DBA files has to be done on the MS-SQL server system locally. The procedure is to copy the respective DBA files for that database into the Hiback\job directory and to change the HI_OPTION entry in the DBA file. The entry contains syntax which is handed to the MS-SQL RESTORE DATABASE command. An example entry is HI_OPTION=”FILE=1,RECOVERY,MOVE 'Northwind' TO

'D:\qa\data\Northwnd2.mdf', MOVE 'Northwind_log' TO

'D:\qa\data\Northwnd2.ldf'”

The restore can be started using the Central Management GUI. Beware to click Overwrite and Wait in the “General options” and to click DBA in “Restore type”. Specify the name of the restore DBA file at “File set definition” as shown below

Click “Start restore” to start the restore. In the “Status” field you can monitor the progress of the restore. You can also monitor the progress of

the restore by changing the view to Monitoring�Job Status. Mark the restore job (you can identify GUI-initiated restore jobs by the word GUI in front of the job name.
