Keeping ARCH and Deleting FULL backups on RMAN

Dear all,
RMAN deletes all my full backup and archivelogs in 2 days with;
DELETE NOPROMPT OBSOLETE RECOVERY WINDOW OF 2 DAYS;
But I want to keep archivelogs at least 9 DAYS and delete just the FULL backups after 2 DAYS. How can i set this?
Any recommendations?
Regards

You reported the Sybrand's post as an "abuse to consider" to the mod. Not to take a part or the other, but Sybrand made several points you should yourself to consider up front :
1. you claimed your problem as an emergency case, it is considered as rude in a public forum based on volunteers.
2. also you did not provided any information which can make difference, as the minimum of Oracle version (and OS...), for one who want to be considered as an emergency, that's rather strange, no one here is sitting next to you
3. Sybrand gave you a command to run that you should see the suggestion resulted
4. He also made a point about the documentation, whether it can appears rude to you, it's always, ALWAYS, good to show exactly to your peers what you have done so far to solve your problem, based on what docs...
5. We could also point you a link such as How to ask question
Please, keep it in mind, and come down.

PS: without saying that 2 mods spent their time to proceed with your faulty reported abuse case

TS3682 I updated to a new phone.. Went to the PC to backup my phone and I get the corrupted backup message.. I go ahead and delete all backups for iPad and my iphone, restart everything from scratch and still get this message. What the hey is wrong?

I have replaced my old iphone. I had an older backup on my pc where I keep my ipad backup as well. I have also updated and verified that the new ios is correct.
Came home and decided to backup the old phone to recover photos, music, apps, etc...
Connecting the old iphone,I get the backup corrupted message that everyone sees.
I go into the backup directory and delete both backups, restart the itunes, restart the PC, and then reconnect my iphone to the pc whihc restarts iTunes.
Tried to backup the old phone again and still the same message...
So, this is the new world where you cannot backup a "smart phone"....
Anyone got any ideas as to what needs to be done?

I've personally never seen this message.
And what it means, quite simply, is that there is corrupted data in your iPhone, so it will not let it make a backup so that the corrupted data does not get saved and passed on.
All you can do here is manually transfer your photos, contacts, calendars to your computer. And then transfer your purchases. You will not be able to make a backup.

If i click to turn off my backup and delete all backup data will I lose everything on my ipad? or will it just no longer be stored in icloud?

currently my iphone and my ipad share data in my icloud account. if i click to turn off my back up and delete all backup data, what will happen? will i lose everything on my ipad, or will it just no longer be stored in icloud?

It will only delete your backup from iCloud.

iCloud only give so much space for free storage, then if you exceed the limit of 5gb you have to pay for additional storage.

What happens after TM deletes full backup & only incrementals are left?

If I understand this correctly, Time Machine does 1 complete backup & then incremental backups after that. If that's correct, what happens when the full backup is about to be erased because the backup drive is full? Does TM alert you to this & ask if you want to create a new full backup instead of another incremental one? Also, is there any way to get TM to create a log so you can see at a glance what's in the incremental backups without having to click through all the folders in each one?
TIA,
Elllen

Answering this dives into how files are represented on a disk. Basically, a disk is a huge expanse of storage space and an index/catalogue/"table of contents". When you copy data to a disk you physically copy the data into the storage space and then make a reference in the index as to where it resides on the disk. The operating system sees the reference, and doesnt go scouring the disk for files whenever you open a folder. This makes finding files and tracking their locations in the directory tree much easier. A single index-link to a storage chunk is called a "hard link". When the operating system "deletes" a file, it doesnt erase it from storage, but instead just removes the "hard link" index entry.
Since files are referenced through an index instead of reading the actual storage space of the disk itself, you can have multiple references in the index to the same chunk of storage space. Hence, you can have multiple hard links which are essentially the same file.
Keeping that in mind, read on...
Every "incremental" backup is a representation of the full backup, including the first "full" backup. Its no different than any other backup (the only difference is that it was the first one so it took longer to copy everything over). Once a file is copied over to the backup disk, it is referred to by a "hard link" in the disk's index. This is essentially how a disk points to a file on any drive. It copies the data over and then creates a hard link to the file's physical location on the disk, which is how the file is accessed by the operating system (or rather, howe the operating system knows the file exists on the disk). You can have multiple hard links to a file, where the same allocation of disk space is pointed to by two different hard links in the index. As such, you can have two representations of the same file (and therefore two links to it) represented on the same disk. If you delete one of the hard links, it will behave as if it's deleted the file, but in fact the file will still remain on disk and will be accessible through the second hard link.
Note that this is different from an Alias (which is also called a "soft link"), which is a file in itself that points to a single hard link. An alias can be removed without the original file being touched.
When TM does the initial backup it copies all the contents over to the backup disk, and then creates hard links to those files which it represents in the first backup folder. When the next backup occurs, any changed files are copied over with new hard links created. The unchanged files, however, are not copied again but instead are just referred to again with new hard links in the new backup folder. As such, new files have one hard link to them (until the next backup), and the old files have two (one in the current backup folder and one in the previous folder). This creates a situation where if the first backup folder is deleted, the original files that were copied are not lost, as they are still represented by hard links in the newer backup folder, and can be accessed that way.
So, why is this different than creating aliases to the original files in the initial backup? Since aliases are just files that point to hard links, if Aliases to the original backups were used instead of hard links, when the original hard links in the initial backup folder are removed the aliases would no longer point to anything anymore and the files would be gone. This defeats the purpose of a backup.
When a file changes from the initial backup, on the next backup the newer version will be copied over and a new hard link to it will be created. If you delete all hard links to the initial backup (by deleting the initial backup folder) the newer file will still be there in the new folder but all references to the old file will be gone and you'll be left with only the new file (along with everything else that was unchanged).
Now to answer your question: Basically, when the old backups are deleted by Time Machine, its not the full/initial backup that's deleted, but only the old versions of files that have been changed. All the original files that were not changed are still there, represented in every backup (new and old) by hard links.

You can issue a LIST BACKUP SUMMARY command. When you see the list of backups available. You can then go ahead and delete backups using the DELETE BACKUPSET <backupset id> command.
By the way, check out TAHITI.ORACLE.COM for documentation on RMAN.
Good luck

Time capsule and deleting old backups

Hi after performing a recent backup to an external drive I don't have much space left on the disk. It says that time capsule will delete old backups. Does this mean that any movies backed up in these early back ups will be deleted as I no longer have them on my MacBook due to the amount of space they take up?

Time Machine is not an archive, it is a rolling backup.
If you want to keep files permanently, you must not store them only in Time Machine. If you don't have space for the movies on your main drive, buy a drive to use as an archive, put those movies on it, and make sure that disk is backed up too, since if data exists in only one place it is vulnerable.
My family digital archive doesn't fit on my internal drive so it is on an external drive. I also maintain two exact backup copies of that external drive. One is in the fire safe at home, the other is in a safe deposit box, and those two backups are rotated periodically. If the original and the backup are lost due to fire, burglary, etc., the off-site backup means there is still a safe copy somewhere. Because I can't afford to lose those photos, movies, and financial records. Online backup is another option for making sure you won't ever lose data you need to keep.

Time Capsule and iTunes full backup problem

Hi,
Every time I add something to my iTunes library the time capsule does a full backup of the entire library rather than just doing an incremental backup.
This has only been happening for the last month or so but it is very annoying and has resulted in my 2TB time capsule starting to delete older backups!
Any ideas why this might be happening and any suggestions on how to solve it?
I could delete all the previous backups and start again but would prefer not to have to do that.
Thanks,
Anthony

have a look at this user tip.

Delete Full backup from Time Capsule

Have searched this Forum and cannot find the final answer to the following question:
I want to delete a Time Capsule full backup sparsebundle for a computer I no longer own.
The iBook gave it up, but there is nothing in the backup that I want or need. There are 3 other computers backing up to the same location and just want to clear more space.
Best way to go?

Douglas S wrote:
Have not tried anything yet. Got confused by some of what I read that just dragging to the trash may not actually delete the backups.
Dragging a local file (on an internal or external drive) to the trash doesn't actually delete it. You have to empty the trash to make it go away completely. However, dragging something on a network drive does cause it to be deleted immediately, as a message should warn you.

Syntax for full backup thru RMAN

hi all ..
i have oracle 11g installed on M5000, Solaris 10
i want to take full backup of my database thru RMAN
i have enter following on backup server
. .db/env
connect catalog rrkas/rr345
(connected)
connect target sys/root123@grid1
(connected)
RMAN> run {
allocat channel dev1 type disk;
backup database
format '/export/home/oracle/dumps/grid3_%t_%sp%p';
release channel dev1;
it started the job.On my dbserver file is created as per the format.
just want to ask, is it the right way to take full/physical backup? Is this backup enough to fully recover the files, in case a new RAC is added to the cluster?
thanks in advance.

If your database is running in ARCHIVELOG mode, this is not enough: you must backup archived redo logs for example with
backup database plus archivelog:Read about consistent and inconsistent backups in http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmcncpt.htm#BABIHBBE and about archived redo logs backups in http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmbckba.htm#i1006454

HT201250 How do I find and delete local backups. This is taking up over 200g of space on my MBP

I recently looked at my hard disc drive and backups were taking over 200gb of space. I used the terminal command to stop taking local backups, but when I rechecked disc space it only moved the space from backup to other.
Is there a way to find and delete this files? Then I can start fresh with Time Machine.
Thanksm
Tp

You don't need to delete local snapshots. They're delete automatically when free space falls below a certain level.

HT201210 I have a message saying "iTunes could not back up the "Owner's iPhone" because the backup was corrupt or not compatible with the iPhone. Delete the backup for this iPhone, then try again. My question is, how do i locate and delete the backup in q

While trying to update my iPhone 4s I received this "iTunes could not backup the i Phone "Owner's iPhone" because the backup was corrupt or not compatible with the iPhone. Delete the backup for this iPhone, then try again. I have a PC and cannot find the backup in question to delete. Any ideas?

Here are location of your Backup folder(s):

System state synchronizations and express full backups of protected 2012 R2 machines overload DPM server.

I have one DPM 2012 R2 UR2 server which is running on Windows 2008 R2 and 2 protection groups (A, and B). The server uses direct attached storage for all replicas and recovery volumes.
Group A protects the system state and bare metal recovery of 25 Windows 2008R2 servers. It creates recovery points using express full backup each night at 6PM. The servers range from file/print, SQL, domain controllers, terminal servers, web servers, etc. Total
data 3TB.
Group B protects the system state and bare metal recovery of only 3 Windows 2012R2 servers. It creates recovery points using express full backup each night (morning) at 1AM. The servers are 1 domain controller, 1 WSUS server, and 1 server that runs VMware VCenter.
Total data 90GB.
During group A's nightly backup, which takes approximately 2 hours, the DPM server becomes noticeably slower but remains functional. I can open Windows update and check for updates, copy files to and from network locations, launch intenet explorer, etc. It's
stressed since 25 servers are creating backups on it but it remains functional.
During group B's nightly backup the DPM server grinds to a complete halt. Launching internet explorer takes an hour (literally), 10 minutes will pass before I get a menu after clicking the start button. Basically it becomes completely unresponsive until the
backups finish which typically doesn't happen because I'm forced to cancel them upon arriving at work...8 hours later.
I read that DPM uses the built in Windows Backup to protect system state and bare metal recovery. Did something change in Windows Backup from 2008R2 to 2012R2 that would cause this? Why can my DPM server easily backup 25 Windows 2008R2 machines at once in 2
hours yet freezes solid for 8 hours or more when backing up only 3 Windows 2012R2 machines?
I left performance monitor running during the night and it showed an average disk queue length of 49 during group B's backup but everything else was normal. Seems the disks on the DPM server are the bottleneck but again I ask why can my DPM server easily backup
25 Windows 2008R2 machines at once in 2 hours yet freezes solid for 8 hours or more when backing up only 3 Windows 2012R2 machines? Both protection groups use the same disks.
How can I fix this?
Teenage angst has paid of well, now I'm bored and old.

Hi CS,
You can also run a performance monitor.
For some basic perfmon counters to help narrow down the possible bottleneck:
