Choice a remote drive for RMAN backup

I want to use my AIX (OS 5.3L) as a remote server for RMAN backup, under the 10g R2. The two most likely drives that still has lots space are hdisk1 and hdisk3. However, the hdisk1 is in rootvg with my test Oracle 10g appl on. Although the hdisk3 is in appvg and but it is the data storage for oracle of local machine. Both drives are quite busy based on the memory monitor and iostat. so How to make a choice for which drive is more proper as a remote drive?

As i play more with the NFS on AIX, i noticed more about the user/group attributes of the files and directory. Mainly, they are different on either side, even more strangely that the new file created on the server side has different user/group attribute , not as oracle/oinstall of original (client side) It worries me whether there will be problem when RMAN does the recovery later.
Secondly, the NFS only allows to write into one level of the directory, which is assigned NSF. As I know, the whole RMAN backup creates backupset files at several levels down from my flash_recovery_area.

Disk V$ Tape Drive for Rman

Hi,
Os : Aix,Red hat 4.2
Db : 10
We taking rman backup which stores in Tape Drive.(It took 11 hours, incremental 0 level).due to ORA-27030 & ORA-19511,we couldn't use Tape drive temporarliy.
So we used disk for rman backup.(It took 4 hours to complete).
Which is best storage(ie fastest) for rman backup /restoration whether DISK or TAPE?
What are the factors determine it?
Thanks & regards,
VN

What is more important to you, then choose. It's simple: tape is more reliable and faster drives. At a cost of not very high volumes, they are about the same per megabyte. It - http://www.allbackup.ru/articles/article6.html - is more less actually.

what is best configuration strategy for rman backup.AND BACKUP WITH RECOVERY CATALOG OR WITHOUT RECOVERY CATALOG
PLEASE TELL ME
Edited by: afzal on Feb 26, 2011 1:45 AM

For simply two databases, there really wouldn't be a need for a recovery catalog. You can still restore/recover without a controlfile and without a recovery catalog.
From this:

CONFIGURE RETENTION POLICY TO REDUNDANCY window of 14 days.I am assuming you want to keep two weeks worth of backups, therefore these:
alter system set control_file_record_keep_time=15 days;
CONFIGURE RETENTION POLICY TO REDUNDANCY window of 14 daysShould be:
RMAN> sql 'alter system set control_file_record_keep_time=22';
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14;22 would give you that extra layer of protection for instances when a problem occurs with a backup and you want to ensure that data doesn't get aged out.

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!

Volume Duplication Policy for RMAN Backups

Hi,
I wish to configure a volume duplication policy for RMAN backups. Both the source media family and duplicate media family are 'content managed' as per the documentation. However, the duplication policy 'trigger' is defined as if the media family is 'time managed', which does not seem to make sense in 'content-managed' media families used by RMAN.
Does anyone have any guidelines on how RMAN volume duplication can be set up so that my duplicates are valid?
Thanks

Yes. I understand. The reason I used time-managed volumes in the tutorial is that with time-managed volumes a duplicate may have different retention and rotation than the original. The procedure for time or content managed duplicates are the same.
A content managed tape may be duplicated to the same or different media family. If to a different media family, the retention would be same...since content managed but it could have a different rotation policy...if desired. For example, if you wanted original tapes left onsite but the duplicates to go offsite for "x" time, then create a new content managed media family and a desired rotation policy...associate that rotation policy to new media family and duplicate tapes to that media family with desired rotation policy. In that scenario, your original media family would have a duplication policy and possible a rotation policy. The new media family would just have a rotation policy.

write a ms dos script for rman backupImpossible. rman does not support MS-DOS. It is not a 16bit real mode application that can be run inside the MS-DOS operating system.
So get your terminology straight - the Windows console is a character based 32bit virtual machine. It is not MS-DOS. It never was MS-DOS. Do not confuse the two simply because of superficial similarities. A stick-it note can be yellow - but because it is yellow does not mean it is a banana.

Using Time Capsule and External FW Drive for TM Backups

Wondering if this can be done, or if anyone is successfully doing it.
Here's what I want to do:
Use a 1TB Time Capsule to backup wirelessly and a FW800 external drive for speed in case I need to reinstall. Therefore having 2 backups? I've been down the road of using SD (cloning) and am ready to move on to another backup strategy. Cloning works fine but it dedicates a drive 100% of the time where TM doesn't.
One thing I did with an old 2.5" 80GB HD in an enclosure that I like a lot is put 10.6.2 on it along with Disk Warrior 4.2, Tech Tool Pro, and Drive Genius to use as a startup and repair disk.

You can do that, but not simultaneously. TM only has one destination a a time; you can back up to the TC, then select the external HD via TM Preferences, then switch back.

I don't know what you mean by that. I use CarbonCopyCloner (similar to SD) in addition to full TM backups, so I have two separate, independent backups, on two separate drives, and get the advantages of both. You can partition an external drive (but not a Time Capsule), so you could have your clone on one partition, and other things in one or more additional partitions (I do that as well). As long as the "clone" partition is the same size as your internal HD (or at a minimum, at least 15% larger than the amount of data on it), you can use the rest of the space for anything else.
See #5 in the Frequently Asked Questions *User Tip* at the top of this forum for detailed instructions on setting-up a drive for Time Machine. The same procedure works for setting one up for a clone and other partition(s), too.

Recommend an external hard drive for a backup for me?

For the first time since I've owned any computer PC or Mac, I need to purchase a external hard drive so I can back up my computer. Over the years I have never backed anything up and have lost some things which at the time wasn't too important. But now with this computer I have lots of music and some very important pictures to me and videos of my grandson I do not want to lose, internet bookmarks etc. etc. I have a program called Time Machine on this computer which I assume is to back up my computer contents. I know nothing about external drives for the purpose of backups. Can someone recommend a reasonably priced one for a beginner and where do I purchase it? Online? Through Apple?
Thanks

I have two LaCie drives - you can check them out here:
http://www.lacie.com/us/products/range.htm?id=10033
Depending on which brand you decide to purchase, you may have to format them for a Mac, which is very easily accomplished by using Disk Utility (Applications -> Utilities -> Disk Utility). At that same time, you may also want to partition it which will create 2 or more partitions on the same drive - each one will act as though it is a separate hard drive. I have mine partitioned and use one just to drag and drop (copy) an extra copy of important pictures or files on it. I use another partition to create a bootable clone using either SuperDuper or CarbonCopyCloner (simple version is free). A bootable clone means that if there is a major problem with your internal hard drive and you can't start up with it, you can start up with the bootable clone because it is an exact and complete copy of your entire system. Then there is the option to use Time Machine; personally I don't use it, so someone else will need to chime in with it. It copies a lot of things and does it automatically every hour or so I believe, but you cannot boot up your computer with it (that is why I've decided not to use it).
Again, depending on the brand you buy, you should not have to install any software that comes with it. An external hard drive should simply show up as an icon on your desktop once you attach it; after that, open up Disk Utility and make sure it is formatted correctly and partition it if desired.
Also, as far as speed is concerned, an external hard drive with Firewire is faster than with USB connections, so keep that in mind. Mine is both Firewire 400 and 800 as well as USB, so I am covered no matter how/where it want to plug it in.

Formatting external drive for storage/backup/video files

Hi,
I just purchased a 500mb My Book Pro external drive for use with my imac duo which runs Windows XP via bootcamp. This computer is shared by three family with very different skills and needs. My dilemma. I want to format the drive so that the imac can be backed up easily three users. It is formated Fat32 and is supplied with Restrospect Express 7.5 backup software. It would be nice to backup the modestly used windows sector, but that's a secondary consideration. My problem is that one user has a lot of larger than 4 gb video files which are too large the Fat 32 format. My notion is to segment the backup drive so that I leave 300 mb in fat 32 to facilitate backup with supplied software, and segment a second 200 gb drive using mac os extended so that the user can manually move her video files for storage/backup on the backup drive. Is there a simpler solution? For example, if I formatted the entire 500gb as mac os extended, could I still run the retrospect backup software? If not, is there a reasonably priced alternative software? And finally, with either Fat32 or Mac OS extended, can I move files from the Windows platform? Would I be better off just biting the bullet and telling my daughter to make her own arrangements to compress and backup her video files or get her own hard drive, thus leaving the backup drive to the simple factory supplied software solution?

Hello,
You're indeed in a pickle. If you use Bootcamp and want the HD accessible via the Mac and WinXP, then you don't want to format it as Mac HFS because WInXP wouldn't be able to access it. If you go FAT32 then both WInXP and Mac OS can access it, but you face the dilemma of the 4GB threshold.
If you format as NTFS, then you eliminate the 4GB threshold but then Mac OS cannot access it.
I have a similar dilemma, which is why i use Parallels more than Bootcamp. I have 2 external FW HD's (160GB/250GB), both formatted to Mac HFS. The 160GB i have partitioned as 50GB and 100GB. I have a bootable backup of Mac OS residing on the 100GB partition (yay to SuperDuper!) and some other stuff on the remaining 50GB. The 250GB is exclusive for movies (cough..cough..bittorrent) and for streaming via Orb 2.0 to my Treo. I have WinXP running in Parallels, and Vista Ultimate via Bootcamp. In Parallels, i can access my external HD's via Parallel's Shared Folders but in Vista (Bootcamp) since the HD's are in a non-Windows recognised formatting, they're not accessible (which is a bummer, as i'm loving Win media center).
What you can do is partition the HD the way you're thinking and format (one part Mac HFS and the other NTFS), but my best recommendation is that with the falling prices of HD's nowadays, why not just get a seperate HD do what you want with it. I spied a WD MyBook 500GB USB HD at CompUSA for $129.99 (no mail-in rebate nonsense) and similar good prices at Bestbuy and Newegg.com.

User Permission for RMAN Backups

Oracle 10g Database Enterprise Edition R 10.2
I have created a user admin and i want to run backups from admin user. Kindly let me know what user permissions i have to grant for rman successful backups?
Thanks!

The rman "client" executable must connect to the Database AS SYSDBA.
Therefore, technically it doesn't require a separate user account in the target database, although you could setup a user, grant SYSDBA to the user and have remote_login_passwordfile configured to allow connections.

External Drive for Storage/Backup?

Ok so I think I'm at the point where it would be a smart idea to back up all my valuable data (as if there was never a smart time to do this?)
Now my question is this: Can an external Hard Disk be used on both my G5 and relatives MacPro at the same time? As in I can dump some files on it from the G5, then plug in into the MacPro and do the same - having seperate storage folders on the Drive for each computers backup?
I've never attempted to do an external drive backup before. I've only ever done it with burning DVDs. So if I'm missing something or this sounds like a silly question please forgive!
Thank you in advance!

I am not too sure you can simultaneously connect one drive to two different machines, in fact I am quite sure you can't and I think that is what you were asking, vs. partitioning it with two partions (easy) and using it on one or the other mac at separate times.
Note by easy I mean it uses the mac partitioning scheme and thus it cannot boot an intel.
As pointed out, there are guides to formating one drive with 2 partitions so it can have two different bootup disks, on PPC and one intel. I would not bother. Seems daunting and if you are unsure of PATA vs. SATA then forget learning that very complex operation.
These drives of adequate (or even quite massive) size don't cost enough to bother. Buy two drives, firewire only and partition one GUID for the intel and the traditional mac format for the other.
And I think you should just buy two already made external (FIREWIRE) drives from LaCie or OWC and not get into buying raw drives, cases and the like and assembling them - you don't save a whole lot if anything, and a lot of these cases are rubbish pure and simple.
Judging by increasingly unhappy posts about the "PC brand" external drives (Maxtor, WD, Iomega) trying to mosey into the mac world I would avoid them like the plague.

DBID for RMAN backup with format '%u'

Hi all:
(I've post this at c.d.o.s. too, but no answers...)
This is Oracle 10.2.0.3 on Enterprise Linux 5.
I've been given two backups from an Oracle Database: one 'cold' and
one 'hot'. They both come from a lost server.
The fact is that they have been made with the format '%u' (eight
alphanumerics) and I must recover the database on a new server. I
cannot get the DBID from the backup files name because of this format
'%u'.
The backups have been made with CONTROLFILE AUTOBACKUP ON (or so I'm told).
How can I get the DBID to recover the DB on a new server?
Thanks in advance.
Cheers.
Carlos.

"The RMAN behavior when the BACKUP command includes datafile 1 depends on the CONFIGURE CONTROLFILE AUTOBACKUP setting.

Reduce Time for Rman Backup

Dear Experts;
rman for 0 level backup is taking about 5:26 hours, backup size is now 312gb I have enabled block track checking & it reduces time for incremental level 1 from 2hour to almost 3 minutes.
database shows biggest tablespace is "users"
I want valuable suggestions for reducing its time or is there any way to break 0 level backup. I can allocate channels but ultimately it will take time when taking "users" tablepace backup
Right now I am taking backup at usb drive & its version is 2.0
Regards

As you are taking backup to a usb drive there is not much that can be done to improve the speed. If you are concerned about the backup being slow.. then you could think of taking the backup on local disk( which would be faster and more efficient) and then move the backups from the disk to usb drive.
This can be done in a single backup script as 2 part operation.
1) take backup to disk.
2) copy the backup to usb drive and delete the backups from the disk.
There are many additional features that u can add to enhance it thoe.
