RMAN backup to disk on third machine

Hi,
How to take backup of oracle database running on machine M1 to the hard disk of other machine M2 using RMAN
Thanks

Hi,
never tried it, but I know that the shared folders in vbox don't work like normal filesystems.
I would rather setup an NFS server on the host and mount an NFS share in the guest.

Rman backup to disk 2 Minutes; Backup to tape hours

Solaris 10
Oracle 10gR2
MML Netbackup 6.0
I have the following scenario
Rman backup to disk < 2 Minutes; Backup to tape takes hours
and occassionaly fails with a media manager layer error.
Any suggestions to speed up the backup to tape?

A backup of under 2 minutes . . . not very big.
A backup to tape of hours?
I don't think that is your problem . . . I think you need to check and see if your tapes are valid. If Oracle fails at the end of a backup to tape, it sounds like the tapes are 'bad'.
If the tapes are good: Then look at why it is so slow - I would 'guess' network backup.
Can you backup to disk and then send them to tape?

Anyone successfully using Oracle 10.2/11.2 RMAN to backup to mounted vbox guest shared folder? I'm thinking there may be some special configuration requirement like there is with NFS share mount options.

Like to take rman backup files into some other machine

Dear all
I like to take Rman backup into some other machine rather than its default storage location $oracle_home/dbs in to some other machine..
While i ran database backup in rman it stores the file sets into default location $ORACLE_HOME/dbs ... I relocated in to some other drivers in same machine also.. I got work ... But due to space issue i would like to take backup into some other machine so its possible ? how to configure it...

RMAN backup to disk vs tape

AIX R 2
Oracle: 10.2.0.4
I have been testing rman backup strategies on a db in noarchivelog (development) using the following command:
(*) note: if db is in noarchivelog then you must do a cold backup - have the db mounted but not opened.
rman> backup database format '/a010/d01/bck/%U'
I have found that rman will backup to disk about 2GB per minute. Now I want to test this to tape to compare metrics.
Question: What configurations does RMAN need to write directly to tape?
What are the backup steps to write to tape? Do I need to specify both the tape channel and also where the format output gets written?
Thanks all.

OK
You need to install the Oracle driver for Tivoli (optionally sold with Tivoli) and install that in your Oracle software tree.
Then you can configure your channels to write to tape (this is documented).
For the rest there is no difference, although there are no directory names.

RMan Backup to Disk Options

Hello,
In Oracle 8.17 on Sun using RMan with a FULL DATABASE backup to Disk can someone please explain:
1. How to specify a tablespace(s) to NOT backup?
2. How to compress the RMan file during the backup (I am low on diskspace).
3. How to break the backup into two pieces and specify a different location for both?
I am not sure if the above are possible. Thanks for you help.
Thanks very much for your advice,
Michael42

Re your 2nd question :-
I've looked into RMAN and on the fly compression ( unix/linux).
It looks like it can't be done well not easily, ( check AskTom or dbForumns if you like).
Several others have tried and RMAN defeats you each time, the problem is that RMAN can't be made to write to STDOUT or STDERR or STD<anything> and thus any "on the fly" compression tools ie:gzip|bzip2| compress just doesn't get a chance at it.
If you are prepared to do some heavy scripting you can use a named pipe into a fixed file name and apply compression through the pipe, but it's a hell of a lot of work and there's a lot that can go wrong.
Re: Your 3rd question :-
Not sure that this will help you 100%, but it may give you an idea or 2.
I splice the DB backup like so; database on one volume and archivelogs on another as follows ...
run {
allocate channel ch1 type disk format '/backupdir1/b_%u_%s_%p.db';
allocate channel ch2 type disk format '/backupdir2/b_%u_%s_%p.arch';
sql 'alter system switch logfile';
set limit channel ch1 kbytes 1024000;
backup (database include current controlfile channel ch1);
set limit channel ch2 kbytes 1024000;
backup (archivelog all delete input channel ch2);
I also limit the size of the pieces.
Hope you get your problems sorted.

RMAN Backup to Disk in a RAC cluster...?

We have a two-node RAC cluster, using Linux and ASM. Pretty typical setup.
We are backing up to disk via RMAN. Right now, that filesystem is mounted on node #1. It's a SAN volume but is not presently clustered.
My questions...
(1) Is it best practice that only one node out of the cluster performs the backups?
(2) Or is there a config where all nodes participate in the backup?
My concerns are what happens when node #1 fails (presumably we'd have to mount the volume on node #2), and also the asymmetrical load during backups.
Thank you!

Hello;
Managing backup and recovery for RAC databases is no different from managing those for single-instance databases.
RMAN backs up the database not the individual instance.

RMAN backup from remote pc !

Dear Friends ,
In my database Linux server I have no enough space to take RMAN backup since my database size around 90 GB .
So in this moment I want to take the rman backup form remote machine(From windows or Linux), where all the datafile backup of my Linux database server also goes to the remote machine . is it possible to do ?
Or is there any way to take RMAN backup(datafile,controlfile,spfile backup from server to client) from remote machine without increasing the HDD space of the Local server ?
Waiting for your kind reply ... ...

Use third party tools like data-protector or use Oracle secure backup to make backups other than local server.

When using compression, you will need to actually test to see which backup compression gives you the best compression/performance. Higher compression = slower performance, Lower compression ratio = more performance.
To make your life a lot easier when trying to do backups, make sure you do rman backup to disk, then sweep these backups to tape. The restore would then be much faster.

RMAN Backups residing remotely

Oracle Version: 11.2.0.3 x64
OS: Win 2008 server x64
Hi Experts.
We need to replicate a database on one of our boxes, with very limited space on disk. The database size is roughly 200gb, free space on disk is 250gb, and the RMAN backups are roughly 80gb.
The RMAN backup pieces have been cataloged with the following path:
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'd:\rman\%d\bkup_%d_%U';So, if we attempt a restore/replication on the local server, RMAN would look for backups on the local D drive, under D:\rman\<db_name>\
In the past we used to copy the RMAN backups on the local server where the replication is required, and perform the replication locally without any issues; however, with a very limited space that won't fit both the replicated instance and the RMAN copies, we're not quite sure how further proceed!?
Can we instruct the RMAN replication session to look for backups in a remote server?
We do keep 3 weeks of RMAN backups on disk, hence the 80GB RMAN backups size. As far as I remember a full backup has been performed last Sun. Can we only bring over Sun full backup (and any subsequent incremental backups)? or do we need to copy the whole thing across to the local server?
Any ideas please?
Thanks

How to distribute RMAN backup among tape volumes in OSB

Hi Guys,
I would like to ask some information about OSB. I have finally set up our Oracle Secure Backup 10.3.0.3.0 and initial OSB backup to tape is good using our test environment.
Now, our production servers has the following details:
Serv01
- Oracle Database 11.1.0.7
- Windows Server 2003 R2
- Current RMAN backup to disk full (level 0) is at 2TB.
Serv02
- this is our media server for OSB and we manage from here all other servers that we would like OSB to be implemented.
-Windows Server 2003 R2
- We have IBM tape library here with four drives
- Our tape volumes are 480GB each (compressed) we about 50 of them.
-Each tape volume has barcodes and our library has barcode reader
How can I group certain tapes (as a media family?) and use them for our level 0 backup. As you know, one tape cannot hold our level 0 backup so we need at least 5 tape volumes to hold our level 0 backup. Is there a step by step process of doing this? Or does anyone know how to do this?
Thanks and I would really appreciate your thoughts about this.

Yes, media families (like tape pools) are used to group backups on tape. Using a database backup storage selector, you set-up media policy so OSB will automatically select appropriate storage when for the backup per your settings. You may want to refer to this white paper which discusses media management:

This is a NetBackup configuration issue. The client doesn't have a policy for your monthly job/schedule. I would recommend comparing the setup of the daily/weekly vs. the monthly job.

Problem in recovery from RMAN backup in case of disk failure

Hi
I have Oracle 9.2.0.1.0 on Windows. Full Hot RMAN backup of database is scheduled on daily basis. I am taking backup on disks. And then i do manually copy them on tapes. If any disk failure occurs than can i recover database completely in this scenario. If tried restoing that backup on different machine as given below
set ORACLE_SID=<name>
rman target sys/<pwd>@ORACLE_SID nocatalog
startup nomount
restore spfile
create pfile from spfile
startup nomount pfile
alter database mount
restore database
Everything worked fine till above steps. Now i will execute last step.
recover database
Here it gives error:-RMAN-06054: media recovery requesting unknown log: thread 1 scn 264750
Still i typed
alter database open resetlogs
Now i can open my database, But is it recovered completely? Or there is loss of some data? Why it is giving this error?
Thanks in advance. Waiting for reply.

I can understand the confusion with this whole concept.
What I meant by all archivelogs is all the archivelogs that were backed up with the backup itself. Again, it is essential to ensure that you archive the current redo log AFTER the backup is performed and then back those archivelogs too. Good thing is, RMAN will take care of this for you if you backup the archivelogs with the BACKUP DATABASE command and/or backup the archivelogs AFTER you run the BACKUP DATABASE command.
Once you've mounted the controlfile and CATALOG the archivelogs, you can go into SQL*Plus and issue the following query:
select SEQUENCE#, FIRST_CHANGE#, NEXT_CHANGE# from v$archived_log
order by FIRST_TIME;This will tell you what archivelog is the latest. Logs generated during the backup may also provide the necessary information. Performing Disaster Recovery should help to understand the full process.
The ONLINELOG directory in FRA is only populated if you've configured your redo logs to be stored there. However, you are on 9i...right? If so 9i doesn't utilize a FRA.
