Image backup and restore in Oracle10gR1

Hi,
I am maintaining a oracle10gR1 database which is stroring texual as well as image data .Database size nearly 950GB.
Can any body suggest what will be the efficient backup strategy so what I can replicate it easily.
Normal export/import it is taking 5/6 days.
Furthermore,We are converting the data in unicode but my NLS_CHARACTERSET is WE8MSWIN1252.Should it work?
Or I have to create a database with NLS_CHARACTERSET AL32UTF8?
Thanks in advance.
Ashutosh.

  • Question about image backup and restore

    W701 about 18 months old.
    I regularly back up using Rescue and Recovery. It says: "Saving an image of your system to your USB external storage device." I haven't found a way to get any clue about what is included in the image. I can't select properties of the backup, or find out what the size is.
    I've also tried google, and of the new info, none of it was useful.
    Does this backup include both drives, C and D?
    And it seems that this backup is just to do a restore on the same computer. If I even replace the SSD with a larger rotating hard drive, I don't suppose I'd be able to use the restore, would I?

    Sankalp,
    I too have the error 0x81000033 when running the full system image backup.  I could not assign a drive letter to my 100mb drive with the Disk Management.  So, I went into the diskpart and ran the following commands:
    diskpart
    list disk
    DISKPART> list par
      Partition ###  Type              Size     Offset
      Partition 1    System             100 MB  1024 KB           ( 78.2 of 96.0MB free )
      Partition 2    Reserved           128 MB   101 MB
      Partition 3    Primary             73 GB   229 MB
      Partition 4    Recovery           423 MB    74 GB
    sel dis 0
    list par
    select partition 1
    assign letter=q
    fsutil usn queryjournal q:
    fsutil usn deletejournal /D q:
    After diskpart, I opened the "My Computer" and see that I have 78.2 of 96.0MB free.  Despite that, I ran these commands on the new q: drive:
    C:\Windows\System32>q:
    Q:\>fsutil usn queryjournal q:
    Error:  The parameter is incorrect.
    The FSUTIL utility requires a local NTFS volume.
    Q:\>fsutil usn deletejournal /D q:

  • Windows 8 full system backup and restore to new laptop (system with 32GB mSata Cache)?

    Hi, I have a new Envy DV7-7205 which has 2TB storage with 32GB HDD Cache (or mSata, not really sure how it's implemented). I need to return the laptop as it's faulty but I would like to startup on the replacement exactly where I left off.
    Are there any special methods required to backup and restore the system image from the old laptop to the new one, particularly with consideration to the 32GB SSD cache, as this doesn;t seem to appear as a distinct "drive" on the system.
    Please can anybody advise the simplest, safest method to move my entire system from old to the new laptops (should be exactly the same spec machine).
    Many thanks,
    Greg
    HP Envy DV7-7205tx, 2x1TB HDD, 32GB mSata Cache, Windows 8 Pro

    Hi,
    Firstly I don't know how this is going to work on new machine because the Windows 8 lisence would NOT work at all.
    Regards.

  • Has anyone sucessfully used the new Winclone 3.2 to backup and restore  Bootcamp partittion with Windows 7 Ultimate on MBP with Lion 10.7.3?

    Bought late 2011 MBP 17" with Bootcamp partition (Windows 7 Ultimate) and Lion OS 10.7.3
    I am trying to make a backup of Bootcamp partition before I start using my laptop but it proves to be a difficult task.
    I don’t have any installation disk for Windows 7 and I am afraid that, if a disaster strikes and I loose the HDD, my copy of Windows will be gone. 
    The only way to restore Windows partition according to what I read so far is to do the following:
    • Use Windows to backup data from BootCamp Partition
    • Reinstall OS Lion formatting full hard drive in the process
    • Use BootCamp Assistant to create BootCamp partition
    • Install Windows 7 on bootcamp partion
    • Use Windows 7 to restore data from backup file created in the first step
    The only problem is that I don't any image or disk to re-install Windows 7. With Windows 7 I can create only 'repair disk' (for what it is worth) or system image but according to other users it would format the whole drive including OS Lion partition when reinstalling
    Winclone 3.2 seems like the answer to my prayers but would like to hear from the users if it worked for them (most imprtantly, did the restore work?). 

    Got the response from Winclone regarding my confusion in step 18 of the procedure to create bootcamp backup.  The message displayed on the screenshot under step 18 can be ignored.  It refers to creating a Windows partition using Boot Camp Assistant but in fact this partition has already been created in earlier steps using Disk Utility. 
    I bought Winclone 3.3 as it promises to make backup and restore of Bootcamp partition with Windows 7 on it really easy, the steps to do this task are easy and well documented, and the owner of the program was very prompt responding to my queries.
    I performed the following as an insurance against disaster prior to creating Winclone image:
    Since my Windows 7 came pre-installed but without any installation disk I used Windows 7 to create 'Windows 7 system image' . From what I read on forums the system image created using Windows 7 apparently can't be used to easily restore Boot Camp partition (as it wipes out OS X in the process).  I created this image as a last resort backup rescue - some users reported that it can be used to recover Windows but the process is painful and involve a number of steps, swapping hard drives, and paid software to assist in the process.  I did not bother to make notes on this process - thanks to Winclone I am not suppose to need this backup if everything works as promised
    I also created 'Windows 7 repair disk' prior to running Winclone.  Not sure what the value of it will be but again, this is something I did just in case I need it in the future
    Then I installed Winclone 3.3 and created Windows 7 Ultimate Boot Camp image without any problems (on MBP running Lion 10.7.4).  My Winclone image file of 150GB Windows 7 Boot Camp partition prior to installing any programs and without any data on it ended up being nearly 8GB (saved to the external USB HDD).
    I have not restored and don't plan to restore the Winclone 3.3 image just to test if it works (don't want to risk loosing my perfectly well running Windows 7 in case of any disaster).  So ultimately only time or experience of other users will tell me if I spent my money well buying Winclone 3.3.  I  know it worked for you JBLTZ so hopefully it will work for me when I need it one day.
    Cheers
    Swavek

  • The backup and restore function in windows 8.1 seems is changed!

    Here's an article that will help:
    http://windows.microsoft.com/en-us/windows-8/what-happened-to-backup-restore
    In previous versions of Windows, you could use Backup and Restore to back up your files or create and use a system image backup or repair disc.
    Windows 8.1 gives you choices about how you can recover your PC and back up your personal files.
    Reset or refresh your PC
    If you’re having a problem with your PC, you can refresh Windows without losing your photos, music, videos, and other personal files. You can also start over by resetting it to factory settings. For more info, see
    How to refresh, reset, or restore your PC.
    Back up or restore personal files
    You can use File History to back up the files on your PC in the Documents, Music, Pictures, Videos, and Desktop folders. Over time, File History builds a history of your files. You'll first need to set up a File History drive and turn File History on. For
    more info, see
    Set up a drive for File History. If your original files are lost, damaged, or deleted, you can restore them. You can also browse and restore different versions of your files. For more info, see
    Restore files or folders using File History.
    Use System Image Backup
    You can use System Image Backup like you did in previous verison of Windows.
    To open System Image Backup
    Swipe in from the right edge of the screen, and then tap Search.
    (If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click
    Search.)
    Enter File History in the search box, tap or click File History, and then click
    System Image Backup.

  • Attempting to use "backup and Restore" giver error message

    In November 2014 I backed up my PC ( see below ) onto  a 2TB ecternal drive ( Lacie).  This ok and can restore.  Spare space 1.2TB
    Now when I attempt to Backup again, using Windows Backup and restore, with same settings  I get an error message :
    "The requested operation cannot be performed on a file with a user-mapped section open"  This appears after some time of activity. There is no mention of WHICH file causes the problem.  I have repeated with different settings ie with
    part backups only, or just one drive only.
    The PC runs Windows 7 ( 64 bit) there is an SSD c: drive and a d: drive mostly data with some programs installed here.
    I would very much appreciate some advice.

    Hi and thank you Mandy.
    After many failed attempts - even backing up a few files to test - I was getting nowwhere.  Eventually I succeeded after disabling start menus and uninstalling some programs.  I also disabled my Kaspersky anti-virus completely and disconnected
    the internet!!  This time the backup and system image appeared to be OK .
    You have helped, Mandy, by identifying the anti-virus as a possible culprit!!  Thank you.  Next time I backup I will just
    temporally disable it and see what happens.
    Kind regards

  • Restore Backup made with Backup and Restore W7 x64

    Hi ....
    Im really looking for some help here...
    I had my laptop stolen and my now trying to recover a 2013 Backup Image made with a Windows tool called Backup and Restore.
    The backup was made with a W7 SP1 64bit using Windows own Backup/Restore utility to create a system image on an external HDD connected by USB port. 
    The application saved the image into a folder called WindowsImageBackup. Inside this folders there are 2 *.VHD file
    So as my laptop was Stolen, im trying to recover this old Backup and save my files again.
    I would like to restore that previous Image. These are the steps I took:
    1) Plugged in the HDD.
    2) I went to Control Panel->Backup and Restore.
    3) I selected 'Select another backup to restore files from'.
    4) In the Restore Files (Advanced) dialogue, my backup isn't showing into the box, because its on my external drive, so i choose browse network location
    5) I clicked 'browse network location' button, and it takes me to another restore files (advanced) dialogue that asks for network folder path.  I tried to locate my external HD, without success. So i tried Search Network. As i also have a copy of my
    backup on my NAS, i tried to inform the network IP path, but it didnt locate the backup either. I get the error that windows was not able to find any backup sets in that directory. 
    6) As the step 5 resulted in nothing, i tried the option: Recover system settings or Computer. And then Advanced recovery methods. And finally use previously system image to recover computer. And then Windows asks to reboot the computer and once rebooted
    it starts on recovery mode where it cant find my backup image either.
    So, how can i recover my backup?
    I saw that the Backup created 2 VHD files and also tried to mount the VHD using Disk Management and attaching the VHD. The VHD mounted as drive and i could finally see my files, but most of them are corrupted. So i dont know if im doing something wrong when
    attaching the VHD.
    Can anyone help me please? I dont know what else to try.
    Thanks a lot
    Flavio.

    Hi,
    If you mean that you want to restore an system image in a different computer, then I have to say that it will not work.
    Please see the statement in KB 249694,

    My apps store will not go online with verizon network, but on wifi it works. I am on an iphone 4, verizon.  I tried to do a complete, backup and restore on the phone 1 day before i noticed this problem,  The backup finished but the RESTORE would fail I had an error, could not access Apple server ( some server name I cant remember).
    I have plenty of space available on the iphone,
    8gb free,
    ios version- 6.1.3 ( 10B329)
    carrier - Verizon 14.0
    Modem Firmware - 3.0.04
    Can someone help.
    I tried doing my backup restore on the same computer as I once did a year ago. and THis time I cant do the restore on the iphone.
    computer osx is 10.5.8
    itunes version 10.
    I do not wish to go to ios 7 at this time.

    Settings > General > Reset > Reset Network Settings.
    Basic troubleshooting is reset, restart, restore (first from backup then as new).  Try each of these in order until the issue is resolved.
    If the issue continues, contact the carrier to troubleshoot the network connectivity issues.

  • Not able to sign into Blackberry Protect. Backup and Restore function not working. "Your device isn't associated with a Blackberry ID"

    Not able to sign into Blackberry Protect.  Backup and Restore function not working. Message is: "Your device isn't associated with a Blackberry ID."  My Blackberry Messenger and Blackberry World is working fine so I am sure its not an ID issue on the phone.  I can sign into Link, Blackberry.com and Protect.  I see my device in Protect but cannot send messages or view it on a map.  Times out with cannot reach device message.  BB Protect on Device has a swirling circle beside the on/of switch.  Cannot turn off.  
    I have deleted Link and re-installed.
    I have reset phone to default(factory) and signed in. 
    OS level is 10.2.1.3062
    BB Link is 1.2.3.56
    Solved!
    Go to Solution.

    I managed to figure this out myself. I had to delete the device from the Blackberry Protect website.  protect.blackberry.com.  I wiped my device again and signed in with my Blackberry ID.  I dont know if the step of wiping was necessary as I did not try my backup with the current configuration on the device following the delete.  Restore is in progress for me!

  • 2013 Backup and Restore

    When I go to my backup and Restore and check the job status it tells me there is a backup in progress:
    A backup or restore is currently in progress
    How do I reset this as there is no backup that I have run for some time?

    Hi, 
    According to your post, my understanding is that the job status still shown “A
    backup or restore is currently in progress”.
    Did you delete a old search application and recreate a new one before?
    If so, maybe the old object is still existing in SQL, you can used the following stsadm command:
    Stsadm -o deleteconfigurationobject -id “object GUID”
    To find the object GUID, simply go into Central Admin - Manage Service Applications and highlight the offending legacy service application (Search Service
    Application in the case). You should now be able to see the GUID in the IE address bar. Run the command above, and try your backups again and all should be well.
    For more information:

  • Iphone4 would not restore Error -50. I have tried to restore and it restored it to the point that it created after 5.0 was installed. How can I get it an older restore point from my backups and restore it on another computer? The phone has been wiped out.

    Iphone would not restore---- Error -50. I have tried to restore, and it restored it to the new point that it created after 5.0 was installed. How can I get it an older restore point from my backups and restore it on another computer? The phone has been wiped out. I can see earlier backups in my C:\Documents and Settings\user\Application Data\Apple Computer\MobileSync\Backup folder. There are four subfolders in this address. I need my contacts, photos, and messages back. I know this is a common error but I can not figure it out. I have ran the other troublshoot items in the error steps for 13 and 14 like apple says. Is there a way to call apple and get a step by step of how to restore from another restore point? Does anybody have a solution????

    It tells you to go to Error 13 and 14 if you receive error (-50).
    Here is what I have tried...
    Error 13 and 14: These errors are typically resolved by performing one or more of the steps listed below:
    Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting. I have moved it around to different ports.
    Put a USB 2.0 hub between the device and the computer. Didn't change anything.
    Try a different USB 30-pin dock-connector cable.
    Eliminate third-party security software conflicts. Removed all virus protection and firewall.
    There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.Used the Microsoft fix it.
    Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online. Doesn't matter.
    Try to restore from another known-good computer and network. I do not know how to do this or how to find the correct/full/complete restore point. There should be more information for this.
