Can RMAN Backup to multiple destinations on disk?

Hello -
Does RMAN have the ability to backup to multiple destinations?
For example, local filesystem, as well as a remote location?
Thanks in advance!

Not on another machine but on tape yes.

Can I backup to Time Capsule after disk repair has failed? How can I save my files?

Downloaded and installed most recent edition of Mountain Lion OSX. All of a sudden, drive is full. Delete photos, unused user accounts. MacBook freezes. Shut it down with power button. Now - drive verified. There are issues. Disk repair has failed - says backup whatever files I can and do a restore.
Can I backup to brand new, never synced Time Capsule? All of the photos of my baby, wedding and the rest of the last five years of my life is in the balance.
Help!

If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Can RMAN backup and export datapump executed at the same time?

Hello,
I have several databases that I backup using RMAN and export datapump everynight starting at 6PM and end at Midnight. The backup maintenance window doesn't give me enough time for each database to run at different time. I am using crontab to schedule my backups. Since I have so many databases that need to be backed up between 6PM - Midnight, some of the export and RMAN backup scripts will execute almost at the same time. My question is can my export data pump and RMAN backup scripts run at the same time?
Thank you in advance.
John

Needs must. If you don't run expdp parallel then it doesn't use that much. If it was really killing the system then look into setting up a Resource plan that knocks that user down but this is a big step.
I woud better look into using Rman
system incrementals, and block change tracking, to minimize your RMAN time.
Regards
If your shop needs to do both simultaneously then go for it.
Chris.
PS : One of my shops has maybe 20-30 rmans and pumps all kicking off some simultaneous, some not, from 0000 to 0130. No complaints from users and no problems either. Go for it.

Can rman backups be used to restore to a different server

We are using R12 with 10gr2 database
If i take Rman backups, can they be used to restore on some other test server for cloning and bringing that test server upto date like the production.
I am confues and dont know and This is the only reason i dont use rman for backups, instead take cold backups manually every night as they are used every week to clone some other server for testing purpose
Please advice
Thanks

Hi..
1. Copy the pfile to the new server.
2. startup nomount the database using the pfile.
3. Open a new RMAN session and connect to this database
4. Restore the controlfile, this will bring the database in mount stage
5. Once step 4 is completed, restore and recover the database.
NOTE:-- These are the steps for restoring the database when the RMAN backup pieces are copied to the same location as they are on the main server.If you copy the rman backup to some different location, then you will have to use the CATALOG BACKUPPIECE 'location' command before restoring the database.

RMAN backup into multiple locations

Hi All,
Our database size is 1.4 TB. I am planning to schedule RMAN full backu. But i do not have mount point of size 1.4 TB. We have mount point /rmanbkp1 of size 1200GB and /rmanbkp2 of size 200GB. How can i distribute RMAN backup to these two filesystems.
Can i take tablespace level backups..?
Please suggest.
Thanks
Sandeep Vadlamudi

Hello;
First of all 1200GB, might be enough since you probably are not using all the blocks in the 1.4 TB and will compress you will also lose less.
Can i take tablespace level backups..?
Yes but the value is limited. You cannot for example recover a dropped tablespace.
Test a backup first and get an idea of how much space you really need.
Also once you have a backup how do you free space for the next backup?
You could use the FORMAT command to backup the database to one location and the Archive to the other. 200 GB is not much space.

RMAN backup of multiple dbs

Hi,
I have a question regarding RMAN.
I have 2 DBs in 2 different servers and I do a daily backup of the DBs with RMAN (no catalog, just the rman script) The two DBs are connected through an application that writes on both DBs common and connected data for the applicazion it self, so if one db stops and the other keeps working the data i will find on my application will become inconsistens (or at least I will have differences between the dbs).
Is there a way to create a single RMAN script that does a backup of archive logs and db of the two DBs simultaniously so that I am 100% sure that the data is taken exactly at the same moment, and I don't have to worry about having discrepancies between the two dbs in case of a restore procedure? because if one db needs restore I will need to restore BOTH dbs to have the application up and running correctly!
(hope I explaied it well enough)
I have Oracle 10.2.0.4 EE on Windows Server 2003 R2 SP2
Thank you all!

Hi,
I think you must use data guard configuration.
In data guard configuration databases will be primary and standby database and transport service (SYNC or ASYNC) is send all archived logs to standby
and apply service will apply all received redo logs to standby.
When primary database i failed, then you can convert standby to new primary.
If you will use SYNC transport then you sure you data loss is equal to zero.

Can you oracle 9.2 rman backup to NFS mounted disk?

Running is disc space issues.
We're using oracle 9.2, can we run rman backups to an NFS mounted disk?

to RMAN there's no difference between local mounted disk or NFS mounted disk
It's just a mount point with some directory structures.

Duplicate RMAN backup output to multiple destinations

Hi
We run Oracle 10.2, we have a requirment to duplicate the rman backup to three destinations at the same time, given that FRA is defined, following is the backup script:
rman
connect target /
backup as compressed backupset database plus archivelog delete imput;
Of course this will backup to FRA only.
The requirment is to duplicate the rman backup output to FRA , /orabackup1 and /orabackup2 in the same one command, i.e, without running the backupo three times.
What change would be needed in the script syntax?

Best pratices for RMAN backup management for many databases

Dear all,
We have many 10g databases (>40) hosted on multiple Windows servers which are backup up using RMAN.
A year ago, all backup's were implemented through Windows Scheduled Tasks using some batch files.
We have been busy (re)implementing / migrating such backup in Grid Control.
I personally prefer to maintain the backup management in Grid Control, but a colleague wants now to go back to the batch files.
What i am looking for here, are advices in the management of RMAN backup for multiple databases: do you guys use Grid Control or any third-party backup management tool or even got your home-made solution?
One of the discussion topic is the work involved in case that the central backup location changes.
Well... any real-life advices on best practices / strategies for RMAN backup management for many databases will be appreciated!
Thanks,
Thierry

Hi Thierry,
Thierry H. wrote:
Thanks for your reaction.
So, i understand that Grid Control is for you not used to manage the backups, and as a consequence, you also have no 'direct' overview of the job schedules.
One of my concern is also to avoid that too many backups are started at the same time to avoid network / storage overload. Such overview is availble in Grid Control's Jobs screen.
And, based on your strategy, do you recreate a 'one-time' Oracle scheduled job for every backup, or do your scripts create an Oracle job with multiple schedule?
You're very welcome!
Well, Grid Control is not an option for us, since each customer is in a separate infrastructure, and with their own licensing. I have no real way (in difference to your situation) to have a centralized point of control, but that on the other hand mean that I don't have to consider network/storage congestion, like you have to.
The script is run from a "permanent" job within the dba-scheduler, created like this:
dbms_scheduler.create_job(
        job_name        => 'BACKUP',
        job_type        => 'EXECUTABLE',
        job_action      => '/home/oracle/scripts/rman_backup.sh',
        start_date      => trunc(sysdate)+1+7/48,
        repeat_interval => 'trunc(sysdate)+1+7/48',
        enabled         => true,
        auto_drop       => false,
        comments        => 'execute backup script at 03:30');and then the "master-script", determines which level to use, based on weekday from the OS. The actual job schedule (start date, run interval etc) is set together with the customer IT/IS dept, to avoid congestion on the backup resources.
I have no overview of the backup status, run times etc, but have made monitoring scripts that will alert me if/when a backup either fails, or runs for too long. This, in addition with scheduled disaster/recovery tests makes me sleep rather well at night.. ;-)
I realize that there (might be) better ways of doing backup scheduling in your environment, since my requirements are so completely different than yours, but I guess that we all face the same challenges in unifying the environments as much as possible, to minimize the amount of actual work we have to do. :-)
Good luck!

Restore backup piece from tape to disk?

Hi,
Is it possible to restore rman backup piece from tape to disk? Please advice.
Thanks,

Is it possible to restore rman backup piece from tape to disk? Please advice.I dont think so it is related with ORACLE database to copy backup pieces from tape to disk.
You might have any other vendors like veritas, Symmetrix & all. We backup an Oracle database via the TDP application to tape

RMAN backup destination changed to Disk

11.2/Solaris 10
We had set up the backups for a DB to go to Tape using
CONFIGURE DEVICE TYPE SBT_TAPE PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default This was working fine.
Yesterday we had to take an Ad hoc cold backup for this DB to Disk .Using FORMAT parameter to point to the disk location, I took this backup in NOCATALOG mode ie. using Control file as the catalog.
Now , when i connected to the catalog for this DB and did a SHOW ALL; I can see that backup location is changed to Disk even in the Catalog.
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 1; This happened due to the resync. I guess.
So, whenever I take Disk based backups using Control file as the catalog , I have to connect to the actual RMAN Catalog schema and revert the Backup location to SBT_TAPE using
CONFIGURE DEVICE TYPE SBT_TAPE PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default?

Configuer is RMAN command which change permanent RMAN configuration settings.
CONFIGURE DEVICE TYPE SBT_TAPE PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
Above would be permanent for external tape drive.
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 1;
You have overrided persistently from tape to disk.
You can set on the fly for backup location by using
run {
allocate channel ch1 type DISK;
backup database plus archivelog;
release channel ch1;
}If you want to have backup at tape cartridge then
run
ALLOCATE CHANNEL ch1 DEVICE TYPE sbt
PARMS='ENV=(OB_MEDIA_FAMILY=daily_bkp)';
BACKUP DATABASE;
RELEASE CHANNEL ch1;
}

Need inputs on RMAN Backup n Recovery for multiple restore of clean backup

I will explain my scenario below:
We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
Please suggest me the best way forward...
Many Thanks

Oracle 9i RMAN backup filling up all disk and failing at the very end

Hello to all and thank you in advance for any input from any of you.
I am new in oracle and the only one in my company with a little bit of oracle knowledge, which is not a whole lot.
I inherited a few servers (Linux and Windows based). We mostly run all our production environment on a Linux box hosting oracle 10g release 10.2.0.1 but we had a legacy application server that still runs on 9i release 9.2.0.1.0. This server is a windows 2003 box, the previous DBA or someone else with admin rights to this machine compressed the whole drive where oracle resides, when I started summarying the oracle assets, I saw this server with no backups scheduled and a compressed disk with very limited space after this compression, only 13 GB left, the database if uncompressed would definitively filled up all the disk. The machine is in used and cannot be taken down for more than a couple of hours. We tried adding another disk but the machine only accept it as a hot spare. The database is in archive mode, when I tried to run a RMAN backup, it start filling up the database drive until it's empty and it crashes the whole machine, it seems like the buffer is growing and growing until it fills up the whole drive. The only way to get the server up and running again is to reboot the machine since the server is more than 6 years old we are not please with this action because we are afraid the machine would go south in one of those reboots.
Has anyone heard of similar issues when running RMAN on a compressed drive? Can the compressed disk have any involvement in this kind of odd behaviour? I tried running the backup in debug mode and creating a log in a different disk (the one where the backup is going to) and still the same issue. Again any help is much appreciate,
Sincerely,
Alex

Sybrand,
Thank you for your fast response, I am going to use your previous post to answer one by one your question,
1 The Oracle binaries --- on a compressed drive > Yes
2 The Oracle database control files redo log files and datafiles on that same compressed drive? > Yes
3 The archived redo log ditto? > Yes
I know for a fact (as I have been using that in 9i) you can create a RMAN backup on a compressed drive, and you can have your archived redo go to a compressed drive. No problemo! > Excellent good news!!!
But I would never touch the data files. Please note backup sets are multiplexed files consisting of multiple datafiles, so RMAN would need to do some calculations to decompress several blocks at the same time and to calculate a new block and compress it.
Do you have enough space to:
a) (preferred) to make datafile copies instead of a backup >
Not in the drive that hosts the oracle instance but yes on an external usb drive (1TB) I attached to use as a backup repository, maybe this is why I am having these issues. I only have 13 GB left on that drive where the oracle instance resides (actually as I explained in a previous reply to Mark, the server only has 3 slots for disks, two of them as configured as RAID 1 and the other is a hot spare because the RAID configuration manager cannot can only added as hot-spare. The raided disk are partitioned in two, one small partition is for the OS and the other is for the oracle instance). When you said make a copy of the datafiles, I assumed you are talking about doing manual backups, and copying the database after using using "alter tablespace tablespace_name begin backup; then copy the file; alter tablespace tablespace_name end backup;
b) use filesperset=1 on the backup command line, so the multiplexing (and associated calculations) stop. I have not tried the option of fileperset yet but I can tryi it and see if that helps.
Can you post the last few lines of the RMAN log where RMAN bombs out? Note: the last few lines. Not all of it, or you must send some paracetamol in conjunction! >
When I ran the debug option, I stopped the backup at less than 20% because I didn't want to reboot the system in the middle of the production time, the backup consumed at least 3 GB during the time was running. The times I ran the RMAN backup I didn't used the debug option so I don't have a log long enough to send unless you want the last few lines of what I have.
Thanks again for your input,
Sincerely,
Alex
