System database Backups

Should I backup my system databases?

The answer is "yes" for master, model and msdb.
The answer is "no" for tempdb and the resource database.
I usually do my system databases daily, same job as the other databases' full backup.

SAP Production Systems Database backup failed

Dear Guru,
I have been facing a problem with our SAP Production system's oracle database backup for last three days. Our back up goes through TSM server. At night 10 pm we have schedule backup for whole offline + redo log backup, 11 pm check and update optimizer statistic and at 11:30 pm Check Database. For last three days above mentioned backup getting failed and we are not able to get such a details log by which i can understand the issue. But Our Development server and Quality server's backup which are scheduled at 12 am and 2 am, the both backup schedules finish successfully. And in morning all schedule backups of Production systems finish without any errors. The issues is coming only with Whole database backup + redo log Backup which schedule at night 10 pm. I have mentioned the log whatever i have got in below:
07.02.2012     07:30:06     Job started
07.02.2012     07:30:06     Job has exceeded its latest start date
07.02.2012     07:30:06     Job cancelled after system exception ERROR_MESSAGE
Above mentioned logs are showing 1day advance log where i have mentioned yesterdays log. That means it should shows 06.02.2012 instead of 07.02.2012 and time should be 22:00:00 instead of 07:20:06.
Our Oracle version is 10.2.0.4.0/ kernel release 701/BRBACKUP 7.00 (40)
Please Guide me.

Samrat Chakraborty

OK,
this has nothing to do with brbackup or TSM.
You batchjob starts at 07:30 !!!
Means before that, you do not have any action at all.
Then the job crosschecks it has passed its intended startdate and terminates,
which is correct, since you do not like brbackup to shut down your DB at 07:30!
No brbackup is started at all, which is why you get no log and no tsm connect takes place.
I assume, you misconfigured some operationmodes and at 07:30 an OP-modeconfiguration
with batchjobs switches back in place so that the jobs do start too late.
Check RZ04 and the OP mode timetable
If it is not this, it has to be something else with the batch scheduler causing delay
or may be all BTC processes are busy, but this seems unlikely with a start at 07:30 sharp..

Check Portal System Database Backup status

Hi,
we have a portal system and i have performed an online DB-Backup using brtools.
Like DB02 in ABAP Stack, is there a way to display the status of the Backup either using NWA at SAP level or using brtools at OS level ?
Thank you,
Mohan.

This is not possible from the portal page (NWA) but you can view the BRBACKUP logs from the OS level located at /oracle/SID/sapbackup and archive backup logs present at /oracle/SID/saparch.
You can make use of the DBACOCKPIT function from another system like suggested above.

Backups of system databases

can anyone elaborate on the risks associated with not backing up default MSSQL system databases (i.e. master, msdb) etc. When would you need to restore data from those databases? What kind of data do they hold? How often do you back them up?

System databases are the core of your SQL Server. Assume a disaster happens, and you lose your system. If you want your system back you need System Databases.
A corruption to your SQL server can cause at any time, if you need your whole system then system databases are required.
Assume you have all your user databases backup after a disaster/corruption and you manage to restore them to a different system, but still you wont be able to login to servers, all your jobs would be lost etc.
You need to backup those as a minimum when you have changes made to the system, eg Any configuration change, Any settings change, Any job created/updated/deleted, any new login created/updated/deleted.
Ideally as these are very small databases once you should not have much issues backing it up. On a safer side a week once would be enough, but as I said, if there is a major change which impact system databases I would back it up.
Read this http://msdn.microsoft.com/en-gb/library/ms178028.aspx to get an understanding about different system databases.

DBACockpit Configuration - Remote Database backup of Java Stack.

Hi All,
I am configuring remote database backup of my SAP Java stack system.
I have successfully connected the system in dbacockpit. I have gateway installed also on the remote host system. but Database scheduling on DB13 failed.
On the OS of CEN system, I can connect to the host system of the remote using the OPS$ logon and i.e
sqlplus /@SID as sysdba - (It connected, to confirm i querried the v$instance I was also able to shutdown the remote system)

But when I ran the brtools to perform the backup I got this error.

Hi Niyi,
This is a TNS error. The system is not able to connect TNS by using br*tools.
Firstly, check your environment variables. They should be as same as java system environmnt variables.
Secondly, check the link below;

You need to create a synonym and SAPUSER table for the gateway installation <sid>adm user on Java database. By doing so, br*tools will be able to connect to the java database.

Daily database backup runnig on RAC 10.2.0.3 with two Solaris nodes & ASM

Hello,
I'm confused about making daily incremental RMAN backup of a database runnig on Oracle RAC 10.2.0.3 on two Solaris nodes and ASM.
Databases cannot be stopped for backup and point in time recovery is needed.
Please correct me if I am doing wrong:
1) Backup must be Weekly database Level 0 and Daily database Level 1 is appropriate.
2) Is best to use a Flash Recovery Area (FRA) - I've setup one on a separate ASM volume. I have enough space to do the backup on FRA.
3) I am confused about the number channels I need to use. Do I need to use separate RMAN backup channels for each node or I can just leave the default:
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
4) Below are the RMAN scripts I plan to use for
- Weekly database backup Level 0:
#!/usr/bin/ksh
echo BACKUP FULL: $ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup incremental level 0 database TAG bkp_level0_200906010;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
- Daily database backup Level 1:
#!/usr/bin/ksh
echo BACKUP INCREMENTAL: $ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup incremental level 1 database TAG bkp_level1_20090611;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
I'm I doing things wrong?

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 raif

Hello 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.

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,

Hello,
>>'\\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

Database backup problem in DB13

Dear All,
When we take backup from the command prompt using Brbackup or Brarchive it executes the backup process successfully, but when I schedule the same thing in the DBA calendar it shows that job finished but it actually does not take the backup. I have given all parameter required for the backup in the DBA calendar like eg, the scheduled time, the tape generic name, archive type.
Can anybody guide what is going wrong ...because of that I am not able to schedule backup using DB13 tcode.
At present I am using Brtools( Brbackup) to take the backup.
Thanks in adv.

SQL2012 System Databases Restore on a different environment

So While I was playing around I wondered if it was possible for me to setup a similar version of SQL 2012 on a different environment and restore it quickly.
Master Env
SQL 2012 - 3 databases , 2 SSIS packages , 2 Sql Agent jobs and 1 report.
The idea would be to copy this on another Server altogether.
Slave Env
So the first thing I thought was the system database should go across before all else. Now it states that both versions have to be the same which I confirmed using;
Use Master
Go
SELECT
SERVERPROPERTY
('ProductVersion
')ASProductVersion,
SERVERPROPERTY
('ProductLevel')ASProductLevel,
SERVERPROPERTY
('ResourceVersion')ASResourceVersion,
SERVERPROPERTY
('ResourceLastUpdateDateTime')ASResourceLastUpdateDateTime,
SERVERPROPERTY
('Collation')ASCollation;
Both showing the same.    Having backed up both system databases on both sides the restoring of the model and msdb databases where straight forward.
The master was a different ball game and is one I still cant get past
1. Stopped the SQL SERVER on the Slave Env
2. Open Command shell
3. Net Start MSSQLServer /m”SQLCMD”
4. sqlcmd -S. -E
5. RESTORE DATABASE master FROM DISK = 'D:\SQL\Backups\master.bak' WITH REPLACE
Go
what this will do is restore the master database from the live to the slave and this is where the problems begin because once you do that restart the SQL server and get out of single user mode you cant logon .
Question
Assuming the Master has different windows logons to the Slave is there any way once this restore has been done to negate this or do you create a user straight after the restore?
Also with ReportingServices and Integrated Services are they straight forward Db restores ?
Any Help one this would be great!!
As I really want to know how quickly I can jump from one environment to another.

Not very simple. Requires DBA skills.
The standby (secondary) server usually refreshed through database mirroring or log shipping.
BOL: " About Log Shipping (SQL Server)
SQL Server Log shipping allows you to automatically send transaction log backups from a primary database on a primary server instance to one or more secondary databases on separate secondary server instances. The transaction log backups are
applied to each of the secondary databases individually. An optional third server instance, known as the monitor server, records the history and status of backup and restore operations and, optionally, raises alerts if these operations fail to occur as scheduled.
Benefits
•Provides a disaster-recovery solution for a single primary database and one or more secondary databases, each on a separate instance of SQL Server.
•Supports limited read-only access to secondary databases (during the interval between restore jobs).
•Allows a user-specified delay between when the primary server backs up the log of the primary database and when the secondary servers must restore (apply) the log backup. A longer delay can be useful, for example, if data is accidentally changed on the
primary database. If the accidental change is noticed quickly, a delay can let you retrieve still unchanged data from a secondary database before the change is reflected there. "

SAP SQL System Copy backup restore method with ADS(Adobe document services)

Hello all,
i´m preparing a system copy with ERP 6.0 in windows and SQL server with ADS.
I have a doubt, can i do the System Copy backup/restore method with ADS??
or the only method that works is with system export/import in all instances??
Thank you

Hi Oscar,
Is your ADS system separate from your ERP system, or are they on the same server?
In any case, you can use backup/restore to copy a Java system, but you must also make a system export/import for the Java server components. The two work in conjunction, so that the export tool doesn't export your whole database, only the components maintained in the filesystem. If you select the database detach/attach or backup/restore method in the tool when going against the Java system, it will prompt you at the right point in the process to make your Java export as well.
The caveat is that the Java export requires downtime, so it isn't possible to copy a Java system without impacting system availability, as it is with a pure ABAP system.
Best regards,
Matt

Urgent -- need to restore table from full database backup

Hello,
Can somebody tell me the process for restoring just a table from a full database backup?
I did a full online database backup yesterday, and one of my tables got ruined today. I need to restore it as soon as possible, but I don't know how. When I tried flashback tables, it said that feature wasn't enabled. Should I restore the datafile or the tablespace?
Thanks much,
Nora

If you only want to recover the table and not the other objects in the tablespace, and assuming the table was damaged by a user statement (and not, say, block corruption), you would need to recover your backup to a different system, export the table that was damaged, and import the table into your real production database. If you can recover the entire tablespace to an earlier point in time, or if you can lose some committed changes to other database objects, you may have other options.

Backup software is Veritas (version 8.6)
Note: Through this we take backup of our legacy system and it takes around 3 1/2 hour to 4 hours to take backup of 60 GB of our legacy data.
 Right now the problem is our backup software version is old and i even believe, the hardware we have is not sufficient to take daily database backup and fortnightly, SAP system backup.
 The only solution to the problem i can see is
1) to go for another backup device exclusively for SAP system
2) Even go for SQL Agent software used to take backup of SAP system thorugh Veritas.
3) Even upgrade my Veritas version.
 Its a request to GURUS
1) Is the solution, i am thinking to this issue is correct.?? If no then please advice me
2) Please tell me the best backup system in your opinion for my above mentioned system.
Thanks Gurus

Hello,
A indication of the size of each database would be helpful.
However, its NOT a good idea to take only one on line backup a week. What if you have a tape error and cant recover a TL? You have no chance for recovery. This is not best practice. Can the business except a 4,5 or even 6 days loss of data - id guess not.
This is what id do if you don't want to purchase a new device, I would take an online backups from SQL to disk every night - this would be a separate disk! From the disk you can the pick up the backup to take at a time to suit that wont impact the existing backup. Plus you always have two copies of the backup. One on disk, one on tape.
My normal transaction log strategy is similar, again backup to disk, every hour on a production system. Then after midnight move the existing 24 logs into an archive folder. This folder would also be picked up by the existing device at a suitable time before being moved to a 'saved' folder and deleted the next day. Again you always have multiple copies of the data. two on disk, two on tape.
