SAP Backup in Symantec Netbackup envirnoment
Hi All,
In my new implementation, my client already have setup of Symantec netbackup environment for exchange server and file server backup.
We have to use same backup solution for our SAP systems also ( SAP is based on AIX6.1 and Oracle 10g).
Now my doubt is, can we also get /rmt0 in my AIX machine by this backup solution. As tape library is connected to HOST1 and SAP is running on HOST2.
Because as per my knowledge and refering to some interesting threads, To do direct backup on tape by using DB13, we need to do backup test by OS commands.
Please provide a solution if anybody faced same situation or how I should resolve it with your expert suggestions.
Regards,
Ramesh.
Hi,
For you requirement, we would require separate SAP client of Symantec netbackup, then you will get a backint file which acts like a mediator between SAP brtools and netbackup. There are some profiles to be changed as well as some changes need to be done at netabackup level.
Please refer the below link for further details;

Netapp Plug-In for Symantec NetBackup and SMTape
I am trying to provide a solution to a customer that involves SMTape to seed SnapMirror (VSM) relationships across a slow network connection between TX and KY. I've found some really good docs about doing this. However, I would like to be able to leverage the customer's existing Symantec NetBackup and tape library solution to avoid having to procure/connect new tape drives to the six (6) storage controllers in this environment. Is it possible to use NetBackup to trigger SMTape? So far I'm not seeing "YES" in any of the documentation so before I assume "NO" I wanted to bring it up in the community... Perhaps someone out there has solved this for their customer or can provide some insight as to how best to deploy SMTape for this situation.Ontap 8.2P3 (7-mode)FAS3250 HA pair in TX (PROD)FAS6220 HA pair in TX (DEV)FAS3250 HA pair in KY (DR)Symantec NetBackup v7.3Thank you!Greg
Hi GregHi Ahmad I'm also interesting in doing a SMTape using NetBackup. It should be used to get a LPAR Filesystem ( no database) to tape. All should be managed using Snap Creator. Here my theoretical stepsSnap Creator triggers LAPR to get file systems consistent via pre commandSnap Creator triggers snap shotSnap Creator triggers NetBackup to run job via post command netbackup/bin/bpbackup -i -p policy_name -s schedule_name -S....The specifiy NetBackup policy is careate with the set type - smtape option and the whole source vol is selected. Currently this job failes with "Error ndmpagent(pid=3144) source servername: DATA: Backup terminated: backup configuration failure (2) on RPC error: ERROR: BAD ENV OP (for /vol/volname)" Any idea?Furthermore I want to have used the snapshot created by Snap Creator for the smtape process. I've see that there are environmen variables available e. g. SMTAPE_SNAPSHOT_NAME but how I have to use them? And is there any NetApp licensing needed? In document it says no but the NetApp option snapmirror.enable can only be set to on with a vailed license. Thanks for any feeback Thorsten

SAP Backup Service SAP 8.8 and Windows 2008 R2 64 Bit
Dear All ( Mr Gordon)
I am facing problem with the Backup Service on windows 2008 R2 64 Bit.
1)The Service starts - There is no Issue
2)THere is no Backup - Even though i schedule it perform the backup
3)EvenLog has a lot of messages - Messages says some Dll are Missing or Corrupt.
COmpletely Uninstalled the Server Tools and Reinstalled back ,still there is error.
PLease help !

DayalDear Dayal,
Thank you for your trust on me. To be honest, I never use SAP Backup Service. This is because: SQL Server provides its own Backup Service. No other vendor can compete with its build in function.

Hi,
I would like to find out more in detail about backup. What are the backup we need to perform inorder to do a full recovery ? Eg,
1)We need to backup both the sap and also the database right ?
2)For database, if we do a offline backup, do we just backup the archive log ?
3)How about the redo log ? Is it necessary during the offline backup ?
4)What do we backup for the SAP itself ?
SAP + archive log = full backup ?
Regards
LauranHi Lauran
For doing full recovery all you need to have is a consistent backup and the logs generated after that backup.
1)We need to backup both the sap and also the database right ?
Taking backup of database means you can do recovery...SAP backup means you need to take non-database components backup like OS files...in windows NTBACKUP or in unix file system copy...
In a regular basis backup of database is sufficient but once or twice a mnth depending upon ur strategy u shud take backup at OS level.
2)For database, if we do a offline backup, do we just backup the archive log ?
Offline backup means u backup the database when it is shutdown. Db is closed to ensure that it is in a consistent state. Offline backup can be taken along with archive log. If your backup is fyn den archive vl jst be for additional security dat if by chance dat backup creates some problem u an use the archive log accrdingly.
3)How about the redo log ? Is it necessary during the offline backup ?
Redo log is not necessary during offline backup. Offline bakup means the db is in a consistent state and does not need any log files before the time of backup. Redo log are useful when u restore the backup and apply the logs aftr the tym of the backup to bring it to the current state.
4)What do we backup for the SAP itself ?
For SAP you back up the files/folders at the OS level like the /usr directory and the other directories related to SAP. On windows u take the backup of the OS files as well to restore the complete system in case of failure.
So there are multiple ways in which it can be achieved. Depends on the company strategy.
SAP + archive log = full backup ?
The above equation u cannot say it as correct actually as it differs for different situation. It depends on what you include in SAP backup...If u include everything frm DB files to SAP files + the logs then it is correct else if you take backup of only the SAP related files/directories and not oracle then it is not correct.
So better not to conclude in such a way and let it vary according to the situation!
Hope this clears all your doubts.

Hello friends,
its been now more than a week that my SAP backup is not doing automatic backup on the server. i have checked all the settings and nothing is wrong. this happened after i have upgraded to 8.8 version from 2007. when i check the service in windows services, it shows that the service is starting... but it stays under this status forever, i cannot stop it or restart.
did anyone had such a problem before? please help.Hi,
If the service is starting, it means not started. You have to clean reinstall the service tool.
You may use SQL Server backup function directly. That is another option.
Thank,

Symantec NetBackup for Lync 2013
greetings,
Is there any compatibility issue between netbackup and lync 2013? Where can i find a documentation which give detailed steps for backing up Lync 2013 with Netbackup. Which version of Netbackup is supported by Lync 2013?
Thanks,
DennisI would recommend that you consult the Symantec NetBackup expert for the support for Lync Server.
If NetBackup can accomplish the procedures at http://technet.microsoft.com/en-us/library/hh202171.aspx, theoretically, it should be no problem.

SAP Backups ; R/3 & file system
Hello,
What is the different between SAP R/3 backup and SAP File System backup?
what are the files that backing up in each cases
To which back up does the oracle DB fit in. (Data Files,Control files, Redo Logs, SPFILE)
To which back up does the O/S files fit in. (here Suse O/S)
thankxThere is not any concept of SAP file system backup.....it means OS level file system backup.
SAP R/3 backup can backed up all the sapdata(database) files, controlfiles as well as redologs.
OS filesystem level backup can backed up all the files based on your requirement and rotation.
Both backups you can use for restorations.....SAP R/3 backup will take all the responsibilities in backup as well as in restoration.
but in OS level backup first you must know which files need to be backed up and what exactly the all directoruies contains.

What are the SAP backup for SID (SAP DB), Master & MSDB?
Dear Experts,
I'm trying to do backup via tcode DB13 for full backup. Somehow there are 3 database option for me to choose, which are Master, MSDB and SID (SAP DB).
I just wonder what are they.
My concern is which of the above options consists all the customizing data in IMG.
Please advise.
regards,
AbrahamHi Abraham,
Data is in SID (sap db) but if possible you choose all three in one go. Otherwise take backup of SID
Read this one if possible,

Unable to restore SAP backup due to br*tools version incompatibility
Hi Everyone...
Our SAP 4.7 production server is taking online backup to sapbackup folder.
for restoring the data to SAP 4.7 production-dr server, I copied from production\sapbackup folder to production-dr\sapbackup folder.
Further, I installed brtools 6.20 version successfully on production-dr and while restoring data in production-dr server using brrestore command. I was receiving an error as version incompatibility and also couldn't find br*tools 6.40 in SAP market place.
Can you please address the following :-
How can i restore data successfully from production to production-dr ?

Sridhar.Hi Sridhar
Could you refer the SAP Note 12741 - Current versions of BR*Tools

SAP Backup using Unix commands / tools
Hi,
We want to include file system backup process as part of our backup strategy. To test the waters, we are planning to take a backup of the at filesystems level. Following are the filesystems in our production systems. We have a test server (hostname is different), without any filesystems created beforehand. I want to know: 1. Which filesystems will be required from the below:
Filesystem GB blocks Used Free %Used Mounted on
/dev/hd4 2.00 0.20 1.80 11% /
/dev/hd2 5.00 2.07 2.93 42% /usr

GILSAPED:/usr/sap/trans 20.00 17.54 2.46 88% /usr/sap/trans
2. Is it possible to directly backup the filesystems (like /dev/oracleGSPlv)? This requirement is because, when I backup (using tar) /oracle, all the folders in /oracle, like /oracle/GSP, /oracle/GSP/sapdata1 etc, are also backed up. I do not want it. I would like to backup the filesystems directly.
3. Which unix backup tools are used to backup the individual filesystems?
4. How do we restore the filesystems to the test server? Thanks for your advise. Abdul Edited by: Abdul Rahim Shaik on Feb 8, 2010 12:10 PMHi,
I am not sure about your OS as you have not mentioned it...
If it is HP-UX then you can use "fbackup" backup for filesystem...
and IGNITE to backup volume groups..
fbackup will backup the filesystem only... but IGNITE backup creates bootable media for recovery...
With IGNITE (make_tape_recovery) backup you can backup individual volume group.
you can see the man pages for the details...
#man fbackup
#man make_tape_recovery
It will be more easy to guide you if you provide your OS and Filesystem layout and what you need to backup...
If you still want to use "tar" command for backup, use "--no-recursion" option to backup single directory
