Restoring with consistent incremental backup

Hi all,
If I had made consistent incremental backups , and I want to restore because there was failure , is it sufficient to restore the latest incremental backup or all the backup ?
Thank you

and I want to restore because there was failure , is it sufficient to restore the latest incremental backup or all the backup ?When you restore and recover, you do not specify levels, but you restore until a specified time, SCN, or log sequence number or cancel depending on the tool
So now it dependes how far in the past you want to go.

Database restore with just one backup set

Hallo experts,
I got a big problem with restoring my XE database. I have a newly created full backup from my XE. While saving the flashback_area I got a hard crash on my system but I saved the last backup set file on a server. Unfortunately I was not able to save other backup sets and I think, there was a special backup of my control files. The restore on another system does not work because of invalid piece.
The data of this database is necessary for my work. Is there anybody out there who can help to restore the data with the existing backup set.
I did not change the entire structure of my original XE database. I only created to schemas with data in. is there any solution to restore the data.
Thanks for any help.
Holger

Hi you all,
I think that somebody will be interested in the solution of my problem,so I post it here and in german on my website (www.datacubus.de).
My XEdatabase is successfully restored and I walked through some undocumented and not supported features of ORACLE to win the challenge.
The first fact is, that ORACLE XE has a very static structure if you use it as is. The datafiles are predefined and so a manual restore with a foreign backup piece seems to be possible.
Here is my way:
Create a backup of your controlfile
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
Shutdown your database
shutdown immediate
Start the database in nomount mode
[holger@MSA04071]$ rman nocatalog target /
RMAN> startup force nomount;
RMAN> quit
Restore the datafiles
I used the following script to restore the datafiles from the backup piece without any check:
declare
devtype varchar2(256);
v_file varchar2(255);
done boolean;
begin
v_file:='/usr/lib/oracle/xe/app/oracle/flash_recovery_area/XE/backupset/o1_mf_nnndf_TAG20070420T234848_32lfb0w9_.bkp';
devtype:= dbms_backup_restore.DeviceAllocate(type => '',ident => 'D1');
dbms_backup_restore.RestoreSetDatafile;
dbms_backup_restore.RestoreDatafileTo(dfnumber => 1,toname=>'/usr/lib/oracle/xe/oradata/XE/system.dbf');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 2,toname=>'/usr/lib/oracle/xe/oradata/XE/undo.dbf');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 3,toname=>'/usr/lib/oracle/xe/oradata/XE/sysaux.dbf');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 4,toname=>'/usr/lib/oracle/xe/oradata/XE/users.dbf');
dbms_backup_restore.RestoreBackupPiece(done => done,handle => v_file,params => null);
dbms_backup_restore.DeviceDeallocate;
end;
Start this script as sysdba. But by carefull. This only works if no entire change of datafiles had taken place!
Reset DBID
Because of the saved DBID within the datafile, the database can't be opened. But there is a little trick for resetting the DBID.
shutdown;
startup mount;
execute dbms_backup_restore.zeroDbid(0);
shutdown normal;
Delete or rename existing Controlfile
Edit trace file
You have to modify your controlfile script as follows:
1. Only use the CREATE CONTROLFILE... block
2. Delete RECOVER DATABASE block
3. Replace REUSE with SET
4. Replace NORESETLOGS with RESETLOGS
Create new control file
Use the CREATE CONTROLFILE block for creation of a new control file.
Open Database
alter database open resetlogs;
Much work but all my data is back and now I will backup the whole flashback_area to avoid further nightmares.
Bye

HT4137 I want to prompt a backup from a newer iphone to an older phone and it is saying that the iOS is not compatible. How can I update my old device so that I can restore with the latest backup?

I am trying to restore information on an older Iphone and am running into the difficulty of restoring my backup. The backup says its incompatible with the iOS on the old phone so it will not let me choose the latest iphone backup. Is there a way to update my old iPhone before I restore that backup? I already have tried to sync it with the latest version of ITunes. I am nervous to restore to an older backup in case the newer backup will not show up again.

What you have to first do is update your old phone using iTunes. Once done: Settings>General>Reset>Erase All Content & Settings. You should now be able to use that backup.

How to restore from an incremental backup when new datafiles are added

1) Source - We have a base backup and then take differential (LEVEL 1) backups every day. Due to business needs, new datafiles keep added daily in the database. So you will see an incremental backup having new datafiles that got created after the LEVEL 0 backup.
2) Destination - We want to restore this database in the destination host "continiously".
a) I first restored from the BASE FULL - LEVEL 0 . This was successful (restored and recovered, but did not OPEN the database)
b) But restoring a LEVEL 1 now on top of the already restored LEVEL 0 makes the restore start all over again if there are NEW DATAFILES added after the LEVEL 0 backup in the source database.
This is not a problem when no new datafiles are added/modified between the "BASE" and "LEVEL 1" backup.
So how do you "just restore only the new datafiles" instead of "starting from BASE LEVEL 0 restore" again " ?
-Thanks
Srini

Hi Srini,
So how do you "just restore only the new datafiles" instead of "starting from BASE LEVEL 0 restore" again " ?The recovery process after the restore should add the newly created datafiles on the destination host.
Can you check by querying v$datafile in mount mode and post the output?

Restoring itunes library after OP system restore with user file backup option in Windows Vista

Trojan virus hit my computer and we had to restore for a backup. I had to redownload iTunes program, and my songs are not in there. And the songs that were in my original itunes library were saved to my computer, but when i try to open them, itunes opens, but nothing happens. Please help with this! If I synch my ipod to my computer, to the new itunes, will it wipe verything on my ipod, or will it tell me that there are things that are on my ipod that are not in my itunes library and it will ask if I want to transfer them? PLEASE HELP WITH THIS!!!!!

Try this:
Syncing to a "New" Computer or replacing a "crashed" Hard Drive: Apple Support Communities
This will move the contents of the iPod to your computer. and sync the iPod to the computer.
It appears to me that something is wrong/corrupt with your music backup.

How do I get my new iphone restored with my old backup? my old iphone had ios5 and the replacement phone i got has ios4 and it wont let me backup my phone because it doesnt have ios4... i cant get ios5 without restoring my iphone and backing it uo

Basically, i need all my old stuff from my iphone 4 with ios5 onto my new iphone 4. The new phone i received only had ios4. I went to get all my contacts and backup from my old phone onto my new phone and it wont let me because my new phone is only ios4 and my backup from my old phone was in ios5. I cant get ios5 on my phone without creating a new backup of my new phone, which has nothing on it. If i restore it as a new phone and backup virtually nothing from my new phone, will that get rid of all my old backup stuff from my old iphone?

Bottom line is you CANNOT restore to a phone from a backup that has a more recent iOS which is what you're trying to do. Just can't be done.

Trying to delete content and settings from iPhone 4 and restoring with an iBackUpBot backup?

So after iOS 7, I'm experiencing a lot of problems with my iPhone 4 (8gb) with things like the storage filling up too easily with messages. I read a lot of articles online on how to fix the problem and I'm using iBackUpBot to delete all of the SMS attachments. I already did that and I'm ready to put the backup on my phone, but I have to erase all content and settings (right?). So I go into the settings and when I press "Erase All Content and Settings", it comes up with a screen that says "Enter Passcode." I assumed it was your Apple ID password so I entered that but it said "1 Failed Passcode Attempt." Is there any other way to wipe your phone? I have wiped my phone before but I don't remember this happening and I definitely don't remember setting some sort of passcode for this. Or do you reset your phone? I'm just very confused and really need help because it just seemed so easy in the articles I read. All answers are extremely appreciated. Thank you!!

Hi lparisi1117!
If you have made backups and confirmed that they are saved, then you can completely erase the phone by using the information in this article to put the phone in recovery mode:

New computer with 7.01 firefox does not show previous bookmarks tho all other files restored with my ClickFree backup. Found the profile but cant open places.sqlite

safely transferred all my saved files from old dead Vista to new computer with Windows 7 except for my firefox 7.01 bookmarks & QuickNote add on. i downloaded QuickNote but it is blank too. Found the profile C:\Users\AppData\Roaming\Mozilla\Firefox\Profiles\8oy034hg.default & places.sqlite but cant open the file.Windows ask what program I want to open the places.sqlite file & i said Firefox but it doesnt open. How do I open the file & get my bookmarks & QuickNote back. help pls

Why not install and try Firefox portable, it may well be a good troubleshooting step. Try running it from an external memory stick.
The threads you referred to
* [/questions/956861] was closed but never solved
*[/questions/958824] similar
Some system information would help
*How much RAM is installed ?
*What is the total size of the Hard Disk Drive ?
*What is the current amount of free-space in GB ? and as a percentage ?
I try not to use Windows but certainly at one stage a rule of thumb was 20-25% free space should be available. Under about 12% defragging of a disk would likely fail. A page file would need to be larger than the amount of RAM maybe 1.5X , and a hibernate file would be the size of the RAM.
* Do not Hibernate if you are low on HDD space.
I suggest you proceed as follows
#Answer the above questions. I worry you have a lack of diskspace.
#Do a full scan with multiple and up-to-date anti-malware tools. Do not rely on Avast alone. No tool picks up everything. Report back what you scanned with and what was found.
#Backup and keep whatever profiles may be good or may contain recent information such as passwords and bookmarks, but do not use them yet.
#Download a new installer then Do a clean reinstall of Firefox, ensuring that the program folders are deleted before you re-install.
#Now restart, you expect the first restart to work. Close down and try again does it now work OK ?
The detailed instructions in the thread you read [/questions/958824#answer-436552] should help you.
If you have continuing problems is this after a restart of Firefox, or a restart of the Windows Operating System ?

How to restore using increment backup after full backup restore in RMAN?

Hi All,
We have a files of full backup of database after turning on the Archive log.
And after that, daily incremental backup is taken.
Now, i want to restore the the database into a new machine using both files of full and incremental backups. Can anybody give me script for restore of full backup and after that restore of incremental backup?
Thanks,
Praveen.

Praveen,
>>
In my case, i have 2 sets of backups. One is full backup and other is incremental backup. In order to keep the restored database upto date, i need to restore the full backup and then restore incremental backup. Now, i got any idea how to restore using full backup. My doubt is how to update the restored database with incremental backup also?
>>
Restore always looks for level 0 backup, not the incremental backups.
Incremental backups comes in picture during recovery.
During Recovery, Oracle looks for incremental backups, if exists, it will do the recovery with the incremental backups, if no incremental backups available, then, it will look for archived logs.
Therefore, incremental backups never used during restore, they are used only during the recovery.

Can I use an incremental backup disk for a restore function?

I have loaded PSE7 on my new PC. I have a full backup set and also an incremental set created after the full backup. After doing a File/Restore with the full backup set, can I use the incremental set to add the remaining picutures or do I need to do a new full backup first and only use it? If I can use the incremental set, are the steps to load it the same as for the full backup?

I have given up incremental backups because they don't save any time. I have found that the messages in the restore process are misleading. I don't know for sure why, but to restore, I got the best results by restoring the last incremental backup first, then the older ones and the original. If your incremental backups are correct, each in a separate folder or disk, you have a full version of your catalog at the time of backup stored within the folder or disk. I suppose this is to start with the latest catalog version and completing the process by comparing with previous versions, which ensures not adding deleted items.
I'd be interested to get other views on that matter !

I deleted some videos from my iPad mini. Can I restore them with my icloud backup

Please help. I deleted some videos I need. If i reset my iPad mini will I be able to restore with my icloud backup.

If they were in your camera roll when you last backed up, restoring the backup should recover them. The backup will, of course, overwrite any newer data on your iPad so if you want to keep it you'll need to save it before restoring the backup.

What are the steps applying incremental backups to standby database 11g

Hi All,
I have built 11g none ASM standby database from ASM RAC Database. Now I want to apply incremental backup to the standby database from primary but not sure how to do it. I tried following and I had an error “ORA-01103: database name 'ins-prim' in control file is not 'ins-sec'”
1- I have configured standby database with RMAN backup.
2- After finishing installation, I took a incremental backup from primary server(ins-prim) and moved incremental backup and control file to the standby (ins-sec) database
3- I stared standby database nomount mode
4- restore controlfile from “incremental backup location in standby database”
5- alter database mount; and got this error
“ORA-01103: database name 'ins-prim' in control file is not 'ins-sec'”
What are the steps applying incremental backups to standby database with 11g?
Thank you

I build the database from backup and changed from ASM to none ASM and changed location of data files and logfiles. I think this changes makes the standby database as logical one.
You can a have a physical standby with different locations for everything (redo/controlfiles/datafiles), ASM and no ASM etc. I have a such a configuration in production (10gR2)
I build the database from backup
Are you sure you have a standby ? Ins-sec receives the archivelog files from the primary ? How did you proceed to build this database ? I suspect you don't have a standby at all ! If you have duplicated the database ins-sec and ins-pri are independent databases and you won't be able to apply an incremental backup (your script was not correct but it is another story)

ACS 5.3 incremental backup error

Hi ,
I have ACS 5.3 that recently having problems with the incremental backup.
The error is : on demand back failed
and the details is: SQL Anywhere backup utility connection error: insufficient system resources- failed to allocate a SYSV semphorenull .
I mean come on.... and I did not find this error on cisco website.
The ADE.log file is not showing errors/details related to this. Atttached are the files showing the errors
Have anyone faced this problem before? Ideas? Anything?
Regards,
George

Hi George:
with 5.3 I experienced many issues including the incremental backup does not work. whenever I set it to "ON" next time the scheduled backup comes It fails and set itself back to "Off'. I did not get same message you get though.
I finally did two things:
- upgraded to latest patch.
- moved the log collector from the primary to the secondary.
Now things are fine for about 1 month without issues.
Regarding your issue, I think it could be related to resource issue as mentioned in the message.
What is the current DB size that you have?
Note that the message is misleading (messages I got with my ACS are the same) because they mention incremental backup in the message title and then say on-demand full backup failed!
So, you have to specify yourself if the issue with the incremental backup or the full backup?

Incremental Backups Interface Problem???

Maybe it's just me, but doing a simple task like backing up (full / incremental) should be very simple, and I'm having a problem. I should be able to select a backup location (a preference), do a Full backup, then do an Incremental...as many as I want...and at some time I may want to do a Full backup again. But it seems it's much more complex than that...
Here's what I'm doing (obviously wrong):
I've done a Full backup on Drive D in some directory, say 'My Backup'. Fine, I think I have a Full backup.
Now later, I want to do an incremental, and I'm prompted to select a destination Drive (it's D), and then "chose browse to load your previous backup file."
OK, I browse to my D | My Backup directory (that's the previous and ONLY backup location), but I'm warned that a backup file already exists, and do I want to overwrite it. Huh???
An Incremental doesn't overwrite a Full Backup. What am I supposed to Browse to?
And what does "Load previous backup file to determine size" have anything to do with a simple need to create an incremental backup file?
Help hasn't helped. I'm missing something.
I'd really appreciate if anyone can tell me what I'm doing wrong. I obviously don't want to overwrite a Full backup with an Incremental.

See excellent answer in Technical side of the forum

Restore using incremental backup with noarchivelog mode

Hello experts,
We are running SAP on Oracle databse(IN NOARCHIVELOG MODE) for which we are having full offline backup on every sunday and post which incremental backups on rest of the days. We have scenario to do restore db to the state till last friday's incremental backup.
Please let us know the procedure for restoring till that point. If possible using brtools utility(which is SAP specific).
Thank You

Venkateshwar

Recovering a NOARCHIVELOG Database with Incremental Backups
Restoring a database running in NOARCHIVELOG mode is similar to restoring a database in ARCHIVELOG mode. The main differences are:
Only consistent backups can be used in restoring a database in NOARCHIVELOG mode.
Media recovery is not possible because no archived redo logs exist.
You can perform limited recovery of changes to a database running in NOARCHIVELOG mode by applying incremental backups. The incremental backups must be consistent, like all backups of a database run in NOARCHIVELOG mode, so you cannot make backups of the database when it is open.
When you are recovering a NOARCHIVELOG database, specify the NOREDO option on the RECOVER command to indicate that RMAN should not attempt to apply archived redo logs. Otherwise, RMAN returns an error.
To recover a NOARCHIVELOG database with incremental backups:
After connecting to the target database and the recovery catalog, place the database in a mounted state:
STARTUP FORCE MOUNT
Restore and recover the database.
For example, you can perform incomplete recovery with the following commands:
RESTORE DATABASE
FROM TAG "consistent_whole_backup";
RECOVER DATABASE NOREDO;
Open the database with the RESETLOGS option.
For example, enter the following command:
ALTER DATABASE OPEN RESETLOGS;
