Is it possible to recover a hot bkup as clone - with missing undo datafiles

I've got a hot backup of a database from 13th June. This was done manually.
Now that I have come to use this backup - which is simply a copy to removable storage. I have found that the undo.dbf files are missing from the backup.
Is it possible to get this database up and running without these datafiles?
Getting hold of a copy of the datafiles now is not an easy task and would require a large additional amount of archive logs to recover to the point in time when the undo files would have been put in backup mode. I finished my manual process at 19:30 the RMAN backup would have been at 22:00 onwards...

Usually. It is NOT possible.
But if there's not transaction when you did the hot backup, Maybe you can re-create another undo tablespace at mount point, then open database.

Is it possible to recover a single event in iPhoto with Time Machine?

I was looking back through the events in iPhoto (300+), nd found one missing. Not sure why; probably accidentally deleted.

There is a way, but it may well be extremely tedious. If you know the filename of the photo, you can try searching for that either
1. in Spotlight (if Time Machine has not been added as an exclusion in  > System Preferences > Spotlight > Privacy),
or
2 manually through the finder tree:
Backups.backupsdb > ....... > Pictures > iPhoto Library
You'll need to choose a backup that you're fairly certain would have been before the time you think it might have been deleted in order to narrow down the search.
In any case follow the path to an 'iPhoto Library' file on your TM disk. Click once on iPhoto Library to select it, hold down the control key, and click again. Choose 'Show Package Contents' from the menu that appears.
This will open up the package like an ordinary folder. Look for a folder called 'Originals'. From here you can browse through your indivudal pictures for that backup date, but there'll be a lot and it'll probably take you a while.
Using either of the methods above, when you finally find the file on your Time Machine disk, click on it once, press 'Command-C' to copy it, then go back to your normal desktop and press 'Command-V' to paste it.
Open iPhoto as usual and import the photo from your desktop.

Is possible to recover hot.backup of a nonarchive database?

I have read on several books that hot backups must be done on a database set with ARCHIVELOG mode, but it is physically possible to recover a hot-backup of a database that was in NOARCHIVELOG mode. Obviously some transactions would be lost, but it is possible to do it?
I'm trying to do it unsuccesfully (when I try to startup the data base he asme for recovering the database and then always ask me for a archive log file.......)
Thanks

What you have red is correct.
You can't do hot backup on non-archivelog database.

Your script defines functions which will enable you to invoke the backup. But this script only defines functions. You need to invoke them for your backup to work. The sample invocation can look like this (CODE NOT TESTED!!!):
Setup
Initialize
Gethottblspace
BeginHotbackup

I deleted the photos via Finder and empty trash long time ago. The thing is, that I want to recover one event or album. The event appears in the iphoto but when open, it shows "!". Is it possible to recover the photos?

I deleted the photos via Finder and empty trash long time ago. The thing is, that I want to recover one event or album. The event appears in the iphoto but when open, it shows "!". Is it possible to recover the photos?

No. When you removed the photos via the finder you damage the library. Photos should always be removed from the library using iPhoto, never with the Finder.
If you have a Time Machine backup of the library from before you deleted the photos you can restore the library to the Desktop and export that album from it to import into your current library.
It's been too long to be able to try one of the file recovery applications. You sure to have overwritten those files with new files since them.

In GB, I need to insert an audio track. When I try, it obliterates part of the adjacent bridge (track). How can I insert an audio track in an audio timeline without stepping all over clean material? Is it possible to recover the "clean" track bridge?

Am doing an audio timeline in GB. Need to insert a corrected section of track. When I try the insert, it knocks out the top part of the adjacent track bridge/element. How can I insert cleanly in a timeline? Is it possible to "recover" the good track that was "stepped on?"

Undo what?
Insert in a new track?
I don't think so. I've started an audio book and I'm doing chapter long segments (assuming I can make simple corrections, such as ones made in iMovie and numerous other video editing programs. Routine edits in GB are simple and intuitive. I cannot wrap my mind around the fact that I'm prevented from doing a simple drag and drop, import or paste a two-sentence audio clip. Nor can I find any reference to straightforward audio elements.
Any suggestions you might have would be appreciated.

Is it possible to recover ical data lost in a sync?

Is it possible to recover ical data lost in a sync?

Your only bet is to resotre from the Time Machine backup. However when you do this the sync process will promptly delete the calendars again, so you need to work through the slightly convoluted method detailed in this page:

Yes, it is one of the things AirPort Express was specifically designed for.

Possible to recover data from dead HD?

in July of this year, my HD stopped working for whatever reason. i got the folder icon when i started my Mac mini that day and did lots of troubleshooting with no luck. i ended up putting a new one in and all is fine now. EXCEPT all my pics and whatnot is on my old HD. the nearest apple store is 3hrs away and dont plan on making a trip any time soon. is there any way possible to recover the data? what are the possibilities of getting the data over since the old HD stopped working? it didnt spin, it was dead quiet. ive seen alot of those HD to USB data recovery connections to transfer info but dont know if it will work? thanks for the help!!

If it is completely dead in that it is not making any noise indicating it is not spinning etc. then you cannot use any software to try and recover data, these software programs generally only help if the hard disk is physically ok but the data is damaged.
In your case it would appear to be a hardware problem and the only option would be to send it to a specialist data recovery firm. If you went to Apple they would only be able to replace it with a new one (if under warranty) and would not do any data recovery.
The specialist recovery firms would completely dismantle the hard disk and replace faulty parts to enable them to get it working and to copy the data off. Your profile does not indicate your location, but an example firm (I have no personal experience of them) is Datatrak Labs see http://www.datatrack-labs.co.uk/company_profile.asp
By the way, why have you not been making backups? Time Machine makes this so easy it is no longer excusable to not do this. I had a hard disk fail in one of my Macs earlier this year (hardware failure), but because I had a full Time Machine backup I lost nothing.

Is it possible to recover my data from iCloud backup without working wifi? I have as many other upgraded my iPhone 4S to iOS 7.0.2 with the result that the Wi-Fi or Bluetooth no longer works. However, i can connect to iTunes via cable but there is wrong version of backup.

Answer is no.
If you want the iCloud backup you have to have n internet connection, thus WiFi.
The not working WiFi has happened with quite a number of users.
It is not exactly clear what is the cause but there are suggestions to clear it up:
Some people have had success by removing an apostrophe from the iPhone name. If your iPhone is called something like “John’s iPhone” then this might work. Go to Settings > General > About > Name and change it to something with no apostrophe.
Some people have reported success by putting the iPhone into Airplane mode and then going to Settings > General > Reset > Reset Network Settings, but the problem may return.
You could also try going to Settings > Control Center and disable Access on Lock Screen then turn your iPhone off and on again.
Make sure that your router firmware is up to date.
Try backing up your iPhone and then restoring it. Check how to factory reset an iPhone for details.
If nothing is working for you, try contacting Apple or take your iPhone into an Apple Store.
Succes, Lex

How to find out which archived logs needed to recover a hot backup?

I'm using Oracle 11gR2 (11.2.0.1.0).
I have backed up a database when it is online using the following backup script through RMAN
connect target /
run {
allocate channel d1 type disk;
backup
incremental level=0 cumulative
filesperset 4
format '/san/u01/app/backup/DB_%d_%T_%u_%c.rman'
database
}The backup set contains the backup of datafiles and control file. I have copied all the backup pieces to another server where I will restore/recover the database but I don't know which archived logs are needed in order to restore/recover the database to a consistent state.
I have not deleted any archived log.
How can I find out which archived logs are needed to recover the hot backup to a consistent state? Can this be done by querying V$BACKUP_DATAFILE and V$ARCHIVED_LOG? If yes, which columns should I query?
Thanks for any help.

A few ways :
1a. Get the timestamps when the BACKUP ... DATABASE began and ended.
1b. Review the alert.log of the database that was backed up.
1c. From the alert.log identify the first Archivelog that was generated after the begin of the BACKUP ... DATABASE and the first Archivelog that was generated after the end of the BACKUP .. DATABASE.
1d. These (from 1c) are the minimal Archivelogs that you need to RECOVER with. You can choose to apply additional Archivelogs that were generated at the source database to contininue to "roll-forward"
2a. Do a RESTORE DATABASE alone.
2b. Query V$DATAFILE on the restored database for the lowest CHECKPOINT_CHANGE# and CHECKPOINT_TIME. Also query for the highest CHECKPOINT_CHANGE# and CHECKPOINT_TIME.
2c. Go back to the source database and query V$ARCHIVED_LOG (FIRST_CHANGE#) to identify the first Archivelog that has a higher SCN (FIRST_CHANGE#) than the lowest CHECKPOINT_CHANGE# from 2b above. Also query for the first Archivelog that has a higher SCN (FIRST_CHANGE#) than the highest CHECKPOINT_CHANGE# from 2b above.
2d. These (from 2c) are the minimal Archivelogs that you need to RECOVER with.
(why do you need to query V$ARCHIVED_LOG at the source ? If RESTORE a controlfile backup that was generated after the first Archivelog switch after the end of the BACKUP ... DATABASE, you would be able to query V$ARCHIVED_LOG at the restored database as well. That is why it is important to force an archivelog (log switch) after a BACKUP ... DATABASE and then backup the controlfile after this -- i.e. last. That way, the controlfile that you have restored to the new server has all the information needed).
3. RESTORE DATABASE PREVIEW in RMAN if you have the archivelogs and subsequent controlfile in the backup itself !

HT201250 Is there a possibility to recover erased files from an external hard drive that was reformatted by the Time Machine?

Is there a possibility to recover erased files from an external hard drive that was reformatted by the Time Machine?

Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

My iMac has less than 2 years. The hard drive from 1TB just failed. Possible to recover data?

The support store just told me that the hard drive of my IMAC 27" is damaged and the solution is to replace for a new one. Meanwhile, I saw this: "Apple has determined that a very small number of Seagate 1TB hard drives used in 21.5-inch and 27-inch iMac systems, may fail under certain conditions. These systems were sold between May 2011 and July 2011."
I bought my system a couple of months before. Anyone knows if it's the same hard drive?
Another question is. Is it possible to recover recover the data from the damaged drive?
Best regards

If the hard drive has failed then that data is lost. That's why you always need to maintain an up to date backup copy of your important files on an external backup hard drive. Hard drives do fail; being an electro-mechanical device they are the weakest link in any computer.
Hope this helps

Is it possible to recover deleted files from the Microsoft Word app for iPhone? I am desperate.

From the Microsoft Word app they say "Access Word documents from OneDrive, Dropbox, iCloud, OneDrive for Business, or SharePoint" so it sounds like you can specify where they are saved. However, my guess would be that the default will be OneDrive.
To the OP: Have you tried logging into onedrive.live.com to see if you can see your letter there?
