Controlfile backup/restore questions

I am trying to clarify RMAN behavior with repect to controlfile obsolecence:
Here are some details of the environment:
10G R2
NOCATALOG mode
controlfile autobackup on
Daily full backup
Hourly archivelog backups
daily cleanup process (DELETE FORCE OBSOLETE)
flash_recovery_area assigned
REDUNDANCY set to 3
The above setup results in hourly controlfile backups as well as controlfile backups before and after the full backup.
What I have noticed is that the controlfile backups taken for the prior day are purged with each new successful full backup. Wouldn't those earlier controlfile backups be needed to restore the full backups taken before today? Especially since this is a NOCATALOG scenario. Or is that the case only when db structural changes take place such as an add or delete datafile.
Thanks

I haven't seen a recommendation from Oracle on this. What/whom are you refering to when you say it is strongly recommended?The Backup and Recovery Basics guide says:
A recovery window-based backup retention policy provides the most certain recoverability for your data.
Recovery window-based policy is explicitely based on guaranteed point in time recovery for a given timeframe whereas redundancy-based policy does not guarantee point in time recovery for a given timeframe.

Using Lenovo's Enhanced Backup & Restore Questions

Hi all,
I am wondering if anyone has any experience in using Lenovo's Enhanced Backup & Restore.
My situation is that I am thinking of updating the firmware on my MyDigitalSSD 128GB mSATA SSD to the latest version. However, from what I read, the update will wipe the mSATA SSD. Also, at the moment, I have been backing up my C:\ to an external HDD weekly using Lenovo's Enhanced Backup & Restore software.
My question is if my steps below are workable and if the Enhanced Backup & Restore program will restore my system back to the latest backup?
1. Use Enhanced Backup & Restore program to backup the latest image of my system.
2. Update firmware on my mSATA SSD. All data will be wiped.
3. Use my Recovery Discs to restore the mSATA SSD to Lenovo's factory image.
4. Use Enhanced Backup & Restore program to restore the latest image.
Any comments, anyone? Thanks in advance!

You can only restore to the same hub, as the serial numbers have to match.

Backup/restore questions LMS 4.2

Hello,
I have several questions regarding data migration from LMS 3.2.1 to LMS 4.2.We will perform backup and restore procedure on new LMS4.2 server machine .
1. I am wondering what will happen with admin password aftrer restore, and all the other passwords in LMS. What will be effective? What will happen with database passwords?
2. Other thing is : LMS 3.2.1 is installed on D:\ProgramFiles\CSCOpx and the new LMS 4.2.1 is installed in D:\CSCOpx
Will there be problems during restore, because the paths on old and new LMS server are not the same?
3. When to perform the licensing? Should I apply license before restore? I think I would have to apply it before beacause customer has 300 devices and eval license iz for 100 only.
4. Does PI_CM license - Compliance Management License comes with the product? How do we get this license? I am aware that this CAAM is new feature in 4.2 version so I am not sure does the customer have rights on it. They have bought upgrade from 3.2 to 4.1 and they have valid support contract so we will go to 4.2 version.
Thanks!
Marija

Following are the answers :
1. LMS's user info and passwords are stored in cwpass file under NMSROOT\lib\classpath\com\cisco\nm\cmf\servlet, which is also
backed up with DB backup. Hence restore would bring all previous user names and passwords.
2. Ciscoworks has a mechanism which doesn't bothers the install directory. It sets environment variable as NMSROOT which is replaced by
the install directory and hence there should not be any issue. Please note that Inter-OS resotre are not supported.
3. You can apply the license anytime, but it is good to install it before backup restore, else the excess of devices, more than 100
will go to unmanaged state and will have to be brought back to managed state once lic is applied.
4. CAAM lic has to be purchased separately. You can contact lic. team or your accounts team for this.Till that time you can use it with its 60 days eval lic.

Win 7 Backup/Restore Questions

I have questions about Windows 7 Backup & Restore. From everything I am reading, it would appear that the program performs as advertised, but some of the traits I am witnessing just don't make any sense to me, and when it comes to Backup/Restore
(B/R), things need to make sense.
Q1: I have a machine that is configured with three (3) accounts: one is a privileged account (admin), and the other two are normal non-privileged accounts (acct1 and acct2 for reference purposes). I perform the backup from the admin account, backing
up the entire machine (all accounts). The backup completes without error. If I then Restore Files to view what was saved, I am shown the admin account, and acct1 as available to restore. Acct2 is not visible! Why not? Am I not
allowed to restore this account as admin? If it is a permissions issue, then why can I see and select acct1? If I logout of admin and login to acct2, and run B/R from there, the admin and acct2 backups are visible, but not acct1. So I know
the data got backed up, but why am I not able to see all the backup accounts when running as admin? If I had a machine with 15 accounts, does this mean I would have to login to each account to restore its files when rebuilding after losing a drive?
Q2: Backups are tagged by date. If I run B/R daily, it appears that the backup is retagged with a date range. If I wait a number of days to perform the second backup, I may get a second backup entry with the new date. What algorithm is
being used to determine when to extend a backup, and when to create a new entry? Is there a trigger that I can use that will force the creation of new entry, and not extend an existing entry, or vice-versa?
Q3: Everything suggests that with multiple backups, the oldest backup represents a full set of files, and subsequent backups are incremental. Exactly what is meant by incremental. I would expect this to mean that any file that has not changed
since the last time it was backed up would not be part of a new backup. Or stated the other way, any file that has changed since the last time it was backed up would be part of the new incremental backup. If I have 4 backups, will B/R examine all
4 to determine whether a file needs to be included in the new incremental backup (I assume so)? If I have 15 backups will B/R examine all 15 to calculate the new incremental (I assume so)? If I decide to manage space and delete the oldest backup,
will a subsequent backup operation resave all my old files that have not changed since the first backup but are now missing from the backup set (I assume so)? If so, then any space gained by deleting the original backup will disappear after the new incremental
completes. Would it be better to delete only the older incremental backups to free up space?
Q4: If I were writing this program, I would expect that contained in each backup is an index to all the saved files along with their dates of existence. I would have to scan ALL backups to create an index of ALL files with their respective save dates.
I could then compare the current file path and date with the name and date in the archive to determine whether the current file needed to be included in the new incremental. If this is the case, is there some point where deleting some of the older backups
will improve the overall efficiency of the backup operation by reducing the number of backups that need to be scanned to build the current backup file list? If so, what is a good rule of thumb for the number of backups to retain to preserve program efficiency?

Hi,
First question, I'm sorry for never heard this problem, I would made a test in our test enviroment, After that, I would provide the result at here.
For other questions , I would like to suggest you read the link below for some details about system backup.

IPhone Backup / Restore questions

Maybe this has been covered here, but I am confused about backing up the data on my new iPhone -
1) When iTunes says "backing up iPhone" before the sync . . . what is it backing up? Contacts? Music? Pictures? Applications?
2) What does Restore do? It seems to indicate you will lose all of your data on the phone if you run restore.
3) If I replace my phone . . . or Apple does at some point for a battery . . . will the Backup/Restore features in iTunes restore all of my contacts, music, pictures and applications to the new phone?
While most things with the iPhone seem pretty intuitive, this whole process has me confused.
Dave

The backup that is created and maintained by iTunes stores data such as most iPhone settings, email account settings, SMS messages, notes created with the Notes application, recent calls, call favorites, data created and stored by 3rd party applications, and photos captured by your iPhone.
No need to backup iTunes content since your iTunes content remains on your computer and should be included with your computer's backup.
Regarding contact information and calendar events, the iPhone is designed to be synced with a supported application on your computer. The exception to this is with an Exchange account or MobileMe account, which provides for over the air syncing with this data.
With Vista, you can sync contact information and calendar events with Outlook 2003 or 2007, or Windows Contacts for contact information.
A Restore completely erases your iPhone followed by re-installing the current firmware version. After the current firmware version is re-installed, you are prompted to restore your iPhone from your iPhone's backup (which is the default selection), or as a new iPhone or not from your iPhone's backup.
This must be followed by a sync with iTunes to re-transfer data not included with your iPhone's backup such as all iTunes content, 3rd party applications, contact information, calendar events, bookmarks, and photos transferred from your computer to your iPhone.

Backup/restore question

When you do a backup or restore, is any of the information on the microSD card copied/restored? If not, how do you backup the songs, photos, etc., that are on the card? Do you just copy the info from windows explorer? I am running win7RC and have a Tour.
While I'm thinking about it, I would like to get a larger microSD card. What's the best way to transfer the info from the old card to the new one?
Thanks in advance from a new guy
Solved!
Go to Solution.

The backup/restore process doesn't touch the media card. You can just use Windows Explorer to copy the contents of the media card. I just got a new media card recently and I just copied the entire BlackBerry folder onto my PC, then inserted the new card, then copied the BlackBerry folder onto the media card.

ISE 1.2 backup restore questions

Hi all,
I have been looking at the backup and restore procedure for ISE deployments and have to say I have found the documentation to be somewhat confusing in general. Whilst I get the gist of it I have found numerous areas that are grey. This question is the first of many but here we go.
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/user_guide/ise_user_guide/ise_backup.html#pgfId-1073378
Based on that link to restore a failed primary admin node I am left wondering about the state of the licensing. In a deployment that has the licensing configured to utilise the UDIs of the primary and secondary node what happens after you have rebuilt the primary from the ground up?
As far as I am aware when you run up a new node the UDI changes meaning that the license detail is no longer correct - how does this affect the rebuilt node becoming primary again and do you have to rehost the license to reflect the new UDI?

Another question I have is about the restoration of monitoring data to a primary monitoring node that has temporarily failed. As per documentation it states that a manual backup should be taken from the secondary node and restored to the primary to essentially provide the missing events during the outage. I have a couple of questions about this process:
1. What happens when the primary monitoring comes back online - does it sync up with the secondary monitoring node effectively overwriting the events the secondary has or does it just continue on its merry way?
2. To restore data to the primary monitoring node do you need to de-register the primary before restoring the backup taken from the secondary and re-join it to the deployment or do you just restore from the primary admin GUI? As far as I can see this still means that there will be a hole in the data for the period of time it takes to restore from backup.

Important Backup/Restore Question

I lost my iPhone and bought a new one. I backed it up on iTunes however after I started using my new one I forgot to restore the backup onto my new phone.
If I restore the old backup on my iPhone will it overwrite the data that's currently on my new device?
I'm mainly concerned with SMS and contact as my old backup has SMS's I'd like to have on my device however I have some currently on the device I don't want to loose. Same goes with the contacts.
Thank you.

If you restore an iTunes backup, it will completely overwrite everything on your device right now with everything that was on your other device when you backed it up.

Time Machine Backup Restoration Question

Hi and tnxs for reading.
In order to restore an entire time machine backup on a new mac, does the new mac have to run the same version of OSX that was used for the TM backup or not?
In other words, are the old version of TM backup compatible with the following version of OSX?
Example: TM backupped with OSX Mountain Lion. New MAC running OSX Mavericks.
Many tnxs.
Regards.

You will migrate in this case.. otherwise you are going to restore Mountain Lion.
See Pondini.. http://pondini.org/TM/Home.html
He discusses the setup assistant and migration assistant. It only covers up to Mountain Lion but the same stuff applies to Mavericks.

Library backup restore question

I have found this and understand it. I ran a small backup to see how the files get layed out etc on the CD.
Is all the data associated with the songs retained? Artist? Album, etc etc. If I backup/resstore following these instructions, do I end up with my library in the same state as when the backup was run?
What about my podcast list? Is there a way to backup my podcast info? Not the individual episodes but the podcast URL?
These instructions:
http://docs.info.apple.com/article.html?artnum=302392
Wayne

If I backup/resstore following these instructions
What instructions?
Simply putting them back onto your HD in the right place will not get them into the iTunes library. You have to go into iTunes and select Add file/folder to library.
All the info is stored in the ID3 tags in the file.
If you copy only the file anywhere else, all the info goes with it. iTunes (and the iPod and other MP3 players and music managers) & reads this info.
iTunes organizes the files into Artist folders and then Album folders under that.

Dreamweaver FTP accounts backup/restore question

I have Mac OS X, Intel Mac Pro. Prior to that I had a Dual G5
machine... I backed up the entire hard drive. I want to just do a
fresh install of my apps, but I want to know how to import all my
FTP accounts (there are 20+)... Is there a way to just import them
from a specific location?
OH just to let you know, I have Dreamweaver CS3... if that's
critical to know...

To get the files, just copy them into the same location on
your hard drive.
That should happen when you restore.
Can you still get at the Dual G5 machine? If so, EXPORT the
site
definitions from it, copy them to the new box, and IMPORT
them (using DW's
Site Manager).

Sapinst error backup/restore phase create controlfile

Hello experts
I am doing a homogeneous system copy using database specific tools backup/restore.Oracle 10.2.0.5, HP-UX, ECC 6.0
Source = ZD1 and Target = ZD1 (Yes they are both same) Source was a fresh install with brand new Export data (SID = ZD1) and now we are replacing the database with a copy of our existing Dev system (also SID = ZD1)
Restored the backup over target using OFFLINE backup. Have not run any "recover database ...." or "alter database open resetlogs" yet because sapinst is suppose to do this.
My control script looks like this: filename = CONTROL.SQL
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE SET DATABASE "ZD1" RESETLOGS ARCHIVELOG
    MAXLOGFILES 255
    MAXLOGMEMBERS 3
    MAXDATAFILES 254
    MAXINSTANCES 50
    MAXLOGHISTORY 23371
LOGFILE
GROUP 1 (
    '/oracle/ZD1/origlogA/log_g11m1.dbf',
then all the data file paths (which I verified to be correct)
ends with:
'/oracle/ZD1/sapdata4/sr3_61/sr3.data61',
'/oracle/ZD1/sapdata4/sr3_62/sr3.data62'
CHARACTER SET UTF8
Now here is the issue:
1) When I manually run the CONTROL.SQL and then just do a alter database open resetlogs everything is fine. Database mounts and opens fine. However when I run the sapinst it tries to run the CONTROL.SQL again and messes up everything. I would like to skip this phase in sapinst and change ERROR to OK in keydb.xml file. Question is when should I do this ? Before starting sapinst so that it skips this or during the phase it stops and asks for backup/restore ?
2) Instead creating files manually I also let sapinst do this. But it throws an error during control file creation. When I used the above CONTROL.SQL it says must use resetlogs to open database. Then I restored all over again and added the line alter database open resetlogs at the end of CONTROL.SQL
'/oracle/ZD1/sapdata4/sr3_61/sr3.data61',
'/oracle/ZD1/sapdata4/sr3_62/sr3.data62'
CHARACTER SET UTF8
ALTER DATABASE OPEN RESTLOGS;
And then ran sapinst again from scratch and now it throws error file 1 needs media recovery.
This is weird and I don't know why sapinst acting smart here and wont let me do it and when it does it by himself it messes up.
Is my CONTROL.SQL scripts correct ? Whats the best approach here.
Thank you

Hello Nicholas
Thank you. I have replaced the CONTROL>SQL in the installation directory itself. Its in /tmp/sapinst_instdir/ERP/LM/COPY/ORA/SYSTEM/CENTRAL/AS And yes it IS picking up the control.sql that I provided and not the default.
DatabaseSAP
Thank you. I have never commented anything in keydb.xml before. But sounds like a good idea because if I can restore it myself I really want to skip this step. Should I just do it before start of sapinst and what exact lines to comment ? Which keydb should I edit ? I found several but looks like ./ERP/LM/COPY/ORA/SYSTEM/CENTRAL/AS/keydb.xml is the right one.
root@zepsapa1 # find . -name keydb.xml
./NW04S/LM/AS-JAVA/ADDIN/ORA/CENTRAL/DB/keydb.xml

./ERP/SYSTEM/ORA/CENTRAL/AS/log_18_Dec_2011_08_05_17/keydb.xml
Also what exactly am I commenting here ? I see step RunControlScript is the one causing problems and I dont want it to create any control files. Please advise what exactly I need to comment and when. And what about changing the ERROR to OK ?

Question: DB2 V8.2.2 and speed of backups/restore with TSM

Hello,
our database is growing and our backups/restore takes longer and longer. We would like to now, if there is an existing IBM tool, with which we could exactly see where our bottleneck is. At the moment we are backing up with four sessions, a 1,7 terabyte database, we are using automatic buffer and parallelism, we have a four CPU (power 5, 1.9GHz) AIX server. The backup takes nine hours. We have identified five components which influense the backup time. CPU-Speed, SAN, Network, TSM and Sessions.
Regards,
Alexander

Hello Alexander,
just to give you my five cents.
I would recommend too (like Markus Döhr): Test the whole infrastructure for optimizing backup performance.
You have to keep in mind performance of SAN, Server (HBAs, bandwidth of system busses) and network. I would recommend for the network testing, a tool like netperf (originally from HP, but available for all SAP OSs - compiler necessary) to measure your network environment. You should figure out how much bandwidth one session could achieve. May be you should find out first which network buffer sizes TSM uses, to use the same buffers in the tests. For our environment it showed that we need 4 network sessions to utilize a 1GBit LAN completely. You should also keep in mind, that the system should have enough resources to handle the additional I/Os due to the backup without influencing the production to much.
Instead of using big buffers like Eric recommends, I recommend to use the auto tuning of DB2 backup, which comes with one of the V8 Fixpaks (I think with V8.2 (FP7)). In our test it speeds up the backup a lot. Just run the backup with the command:
db2 backup db SID online use tsm open 4 sessions
DB2 will automatically tune the backup to achieve best possible performance.
In our environment we run a 2.8TB Backup with a backup rate of around 600GB/h which consumes only 12,5% of the possible I/O bandwidth. We assume that this should be no problem even when few of our HBAs have problems (this happens not only in theory - already two times this year). We're using Legato Networker and running a 10GB ethernet exclusively for backup. We already saved the database within 2 hours 16 minutes; if necessary we could do even faster. I think the limit is at the moment is somewhere around 1.8TB/h, But this is neither necessary nor it makes sense (because this would have an impact on our production).
Best regards
Ralph Ganszky

Question about backup/restores.

I'm getting ready to backup my dev server and restore what i need on my production server for the first time. What I want to know is if I do a backup/restore in the future to add more to the production server will the restore overwrite the content
that has been add to the on the production server?
Thanks
James T.F
Edit: What I'm trying to do is push the ground work to the production server from dev, and then add updates and modules along the way without losing content on the production server.

RMAN Backup Restore from tape

Hello Gurus
We have lvl0 RMAN database backup restored from tape but due to some reasons we could not apply recovery on it. On checking the information in controlfile, it identified only the system file and no other file. So, we recreated the controlfile and decided to recover using backup controlfile option (until cancel or until change or until time). However, to my surprise, when I listed the checkpointchange# and checkpoint_time columns of v$datafile_header, I found the difference in timestamps ranging 24 hrs -- which menat we had to apply 24 hrs of archiving to bring all dbfs to a consistent state (before it allowed us to open the db) -- so far so good, it worked that way.
My question is that, while I trigger a lvl0 RMAN backup at say 4PM on 27th July and it finishes on 4PM on 28th July (as I am directly pushing around 1 TB data to tapes) -- what is the consistency timestamp of this backup. In other words, is this backup available for a restore of 4PM 27th July? Or is it available only for a restore of 4PM 28th July and later ...?
Isn't it that RMAN works at block level and when I fire a backup it should give me all the dbf's of that timestamp..?
Appreciate your inputs/comments.

When taking a online backup with RMAN, the datafiles backup is always inconsistent because it needs the archived redo logs generated during the backup to be consistent: http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/intro005.htm#sthref70.
A full online backup can only be used to restore the database to a point in time starting after backup end: if a backup starts at 4PM on 27th July and it finishes on 4PM on 28th July you can use it to restore the database to a point in time after 28-JUL 4PM.
