Restoring a tablespace/datafile to a previous date ?
Hello everyone ,
Is it possible to restore a tablespace / datafile to a previous date and not apply changes to it from that date until sysdate ?

consider this very real possible situation:
TablespaceA contains table PURCHASE_ORDERS
TablespaceB contains table PURCHASE_ORDER_LINE_ITEMS, with a FK back to PURCHASE_ORDERS.
TablespceC contains indexes on both PURCHASE_ORDERS and PURCHASE_ORDER_LINE_ITEMS.
Now, you want to restore just tablespaceA back to last week ....

Restore Mac OS X Leopard to previous date
Does anyone know if Mac OS X 10.5 has an option like Window XP to restore to previous date?
ThanksThink also of using for instance SuperDuper or Carbon Copy Cloner to clone your system before updates. That way returning to the previous version is a breeze.
If you have your install discs handy you can do an archive and install to go back to a fresh install.

When I hit "save as" and view the field that comes up, it does not give me the option any longer of saving to my personal file. This problem started a few days ago, when it took me into my personal files and allowed me to select a specific folder to save the document in, but no longer gave me the option of hitting "save" into that file folder. I know that I have made changes in trying to correct the original problem, but now I don't know how to get back to where I was before.no longer
Ah yes school boy error there out of frustration and discontent..
My issue is with music/apps/films etc not downloading from iTunes / App Store.
They initially fail and message is displayed stating unable to download / purchase at this time, yet if I retry it says I've already purchased (?) or alternatively I go to the purchased section and there they are waiting with the cloud symbol..
However some items get frozen in the download window and cannot be retried or deleted. Message appears stating to tap to retry, but even if you stole every bath and sink in the uk you'd still not have enough taps.
I post here as the iTunes guys are useless in there 'help' and have only advised posting here or phoning apple, at my expense, to explain a problem that could be rectified by forwarding my original email to a techie. However the tech team apparently don't have an email address as they're from ye olde Middle Ages..!
Anyways I digress.
So I tried sync to pc, but instead of showing the file as ready to listen/use/view, the iCloud symbol shows and I'm back to square one as the item is unable to download..
At frustration station waiting for a train from pain...
All my software is up to date, and had all worked fine prior to the last big iOS update that resulted in all the changes in display and dismay.
Answers in a postcard :-)

I need to restore my 3Gs to a previous date not reported on the scroll menu : how can I do it ?
I need to restore my iPhone 3GS to e previous date than that reported on the scroll menu : how can i do that ?
I lost all my contacts because , due to a my mistake , I sincronized iPhone with the empty Outlook inside of my Windows cmptr .
Is there any chance available ?
Thanks : dbNo.
If there is no backup available for that date, then there is nothing you can do.
Your contacts should be on your computer in whatver contact program you use. -
Ok. Add me to the moron list. I guess I am an over zealous trash emptier. Can I retrieve those images by entering my time machine and restoring the Iphoto library from a previous date (when I wasn't a moron?)
Masters is where you want to be. They'll be in there in folders based on the date and time they were imported.

When starting a Macbook Pro that has quit by using the disc that came with it, will the "restore from backup" option erase all previous data stored on the machine?

As long as the backup on your external drive is fine, it will restore your Mac to exactly how it was on the date of that particular backup, all data included. I have used it before and have retained all data from the date of the backup.

How do you start the computer from a previous date.
I overloaded my desktop and now the computer is frozen. It will turn on but none of the applictions work. I can pull up preferences. I would like to start my computer with a previous date when everything is working. Please tell me how to do that. I know how to put it in safe boot.
Thanks,To return your computer to a previous date you have to have been doing backups with the Application called TimeMachine. It is turned off, by default. TimeMachine automatically backs-up your user files to another disk or to rounter with a backup disk. When TimeMachine is enabled, you can return to any time or date in the past by running the TimeMachine application and doing a Restore on the date and time you choose.
If you didn't have TimeMachine running or a current backup....
FYI: Microsoft's Windows has a feature to restore it's Registry to a previous date, but that is not backup of the user files. It allows the system to replace the Registry database back to a point where it was not corrupted.
A similar fix for the Mac OS is to reboot the computer and hold down 4 keys to reset the PRAM (that is your system Preferences). This is a very quick fix and it should be the first thing you try. As the system is restarting, hold down the OPTION- COMMAND-P-R keys all that the same time.
Failing that, you can boot the system up in SAFE mode, which brings up the Mac OS without enabling any of the extensions. It requires a wired USB keyboard and mouse - won't work with a wireless keyboard or mouse. Cycle power and hold down COMMAND-S keys on reboot. This will allow you basic access to your system and you can reomove or delete any application that you suspect is causing a problem.
If none of your applications work on the Mac, you can boot up from the gray repair disk (or boot up Disk Warrior or Tech Tools). All of them will clean up the file systems and that is usually all you need to fix things. Insert the disk. cycle the power button (hold it for 11 seconds) and hold Command Key+C (for CD) on your keyboard while it boots back up.
The most common cause for persistient hangs is too little memory (RAM) or the harddisk is full. The RAM problem can be minimized by not running other big applications. If the harddisk is over 80% full, you will see significant slowing. At 90-95% full, the system can barely run. Run Disk Utitliy from the APPLICATIONS / UTLILITIES Folder, as The Hatter suggested (above). Disk Repair is the option.
Note: If any recovery works with a wireless keyboard and mouse, I am not aware of that new functionality. Also, any USB keyboard and mouse will work, even if it's from a PC. -
I went yesterday to the Albany, NY apple store genius bar with a sound issue on the Ipad. After 2 hours the "genius" told me that
they tried wiping my Ipad clean, but not to worry that first everything was saved in the cloud. I was told I had to reload all
purchased Apps and would be no charge and would take some time. Due to the late hour I said I'd do it at home. I did not do
it last night. This morning I open the Ipad to find nothing in it....no contacts, no notes....nothing. I rushed back to the apple
store and was told that apparently last night a backup took place and the Icloud backed up a clean Ipad....no info. This is a
huge problem. Apple personel simply said sorry that the "genius" should have known better. Attempts to restore seems to
only go back to the last backup which of course is blank. Now my question is .....is it possible somehow with the cloud from a
previous date like you can with a PC?You can order recovery media here

I have an IPhone 4 which I just updated with the latest software, which put in it in Recovery Mode. It has the picture of the plug with ITunes, I downloaded it now its saying its in Recovery Mode, how do I save all of my previous data without Restoring?
I updated the phone before backing it up on iTunes, now the update wanted me to connect the phone with iTunes and it says the phones in recovery mode and it must be restored before its used with iTunes. I go to click restore and it says it will reset it to factory default and I'll lose all my current data. I have all my sons pictures and videos along with this notes. I can't lose all of this data! Please help!You have to restore the iPod, no ifs, ands, or buts...
After iOS is installed you will be asked if you what to set it up as a new iPod or if you want to restore from a backup.
If you have a good backup you can restore that and you're good to go.
If you don't have a good backup, then you end up with a "clean" iPod.... -

Yes, you will.

System Restore to previous date
I would like to download a game on my macbook however i would like to set a restore date so that if it slows my computer, i can restore the computer to a previous date before the game was installed. Is there a way to do this on my macbook OS X (processor Intel Core 2 Duo)? Thanks!
Yes. Get a bootable, external HD and put a bootable backup/clone of your present HD onto to, boot into it, ensure that it works like the original. Use Carbon Copy Cloner, SuperDuper!, Disk Utility, etc. to do the backup/clone.
