Recover files stored in ZFS

I have two disks in my solaris system. One is for solaris os and in the other I am using ZFS. Suppose my root disk gets corrupted totally, is it possible to recover files stored in other ZFS disk. (Like in windows we can just connect the disk to other system and recover also in unix we can mount the disk in other system).

Make use of open dataset read dataset and close dataset
check the files using t-code AL11 on the server

Rescue and Recovery tool - problem with recovering files stored on USB memory stick

I recently had to use the Lenovo Care Rescue and Recovery tool to restore my 300 N200 to a previously backed up state.
As part of the Rescue and Recovery I selected the option to save user data in My Documents to a USB memory stick before restoring to the backup. This seemed to be successful (tool confirmed that 300MB of files were saved). But when I wanted to restore the files from the USB memory stick back to the laptop none of the folders/files is visible.
I checked the memory status of the USB memory stick and this confirms that 300MB space is taken up - but no files visible!!!
Can anyone help??

HT201250 I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them?

I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them? No, they were not part of previous Time Machine backups, and I have checked both the hard drive the documents were lost on and the new one that I now use for backups. Any suggestions would be helpful, as the lost files are old pictures that are gone forever. :[ Thanks!

1. Yes, if both drives are formatted as Mac OS Extended (Journaled).
2. Reformat the drives if needed, open the Time Machine pane of System Preferences, and remove the drive with the pictures from the list of items set to be excluded.

[SOLVED] recover files after accidental formatting of zfs

Ok, Let it the 'you are an idiot' comments roll...
Long version:
I wanted to play with zfs, so I was installing freebsd alongside my typical arch installation. During the installation, I was astonished to realize that I must have been confused by the BSD drive naming convention because I had overwritten my data partition with zfs. Of course (I am an idiot) and I had no backup.
short version:
Used to have an ext4 partition that had some files on it. Now I have a zfs partition that has no files on it.
I did not do ANYTHING after I realized the mistake. I didn't even finish the installation. To the best of my knowledge, it has never even been mounted.
What utilities give me the best chance of recovery? Is there anything specific I should know about this specific situation, recovering a journeled file system out of zfs?

Turns out that TestDisk was IS in fact capable of recovering lost partitions after they have been deleted, or sometimes reformatted. According to their wiki, they do not support ZFS filesystem, so I decided to try it in hopes that it would still recover TO a zfs partition.
And, I happen to have a copy of TestDisk handy on my Parted Magic CD.
Steps taken:
-From the main menu on Test disk, Select advanced.
-Select analyze partition data.
-This correctly identified my old linux partitions, and they were marked with a D which means they were 'deleted'. I don't know if it is completely right, because I never bothered to write down the specific Hard Drive geometry before, but it looks right to me.
-hit 'Write' to write the corrected partition table to disk.
-I was able to see recovered files through the testdisk program, but I'll have to reboot for the kernel become aware of the partitions and let me mount them. So I'll be back in 5 minutes to report whether this worked.

Old unreadable hard drives - looking to recover files

I have two old hard drives - both from my first iMac (Bondi Blue, purchased in early 1999). The first one "died" sometime in 2002 (blinking folder/question mark) so I replaced it with the second one. Eventually the second died the same death (both OS9).
I moved on and have been with my G5 ever since (2005).
I've kept the two drives in storage, hoping that someday data recovery at home would be a typical option. Ha.
Last week, looking to fiddle with the old drives, I bought a slot-loading iMac CRT on craigslist for $25, no keyboard or mouse. It has a working hard drive with OSX installed. The keyboard/mouse from my G5 work fine on it.
So I removed the hard drive and replaced it with each of my hard drives. Of course, same old story: each drive was unreadable (blinking folder/question mark).
I don't have the original install discs (in fact I don't have any install discs).
All I have is a Norton Utilities disc, which the computer will not start up from no matter which hard drive (including the working one) I have attached (I suspect that even though I press 'C', the newer keyboard takes longer to be recognized and is not readable upon startup). I also tried booting from the Norton CD using open firmware with no luck.
Bottom line is:
I have 2 "dead" hard drives (blinking folder/question mark):
- Quantum Fireball EX 3.5 Series
- Maxtor D540X-4K 3.5" Series
and I have a slot-loading iMac (CRT) with no install discs and only my G5 keyboard/mouse to use it with.
I've done a lot of research looking for any possible way of recovering files from these drives, but all information inevitably leads to "see a data recovery specialist'.
I imagine I will get the same advice here, but I absolutely can't afford the upwards of $1,000 it could cost for that service.
Am I out of luck completely? Should I put the drives back into storage until I can afford a recovery specialist?
Thanks.

I doubt this would boot. You do not have the drivers on your version of Mac OS to support newer hardware.

Lots of bad reports about Norton. They stopped updating the utility, so user beware.

Is it possible to reassemble a Time Machine backup from recovered files?

I have kind of a sad story that I'm sure some of you can relate to. My Macbook was briefly stolen but by the time I got it back, the partitions had been erased. I had an external backup... but the backup disk failed catastrophically a couple days before it was stolen. The external backup doesn't even mount anymore and makes grinding noises if it's plugged in...
The MacBook had two hard drives in it and one was rather large, so there was space for a partition that I used only for Time Machine. It was erased during the theft, but since nothing had been written to the disk yet, I figured that the chances of recovering data were pretty high. So I went online and looked around for utilities (I used StellarPhoenix... Not sure I'd recommend it to a friend) and managed to spend the next four days recovering the time machine backup to an external computer. I recovered a lot of directories with raw directory IDs attached to them and interesting recovered files inside.
I want to put these files back together as a Time Machine backup (haha, I know right?), because the alternative is around 60 gigabytes of data to sift through by hand.
Here's the top level structure:
MacBook:Root alleygator$ ls -a
.fseventsd
.journal
.DS_Store
.journal_info_block
.HFS+ Private Directory Data?
Lost Folder(s)
.Trashes
"HFS+ Private Directory Data?" and "Lost Folder(s)" directories contain about three hundred thousand directories altogether.
.journal is 33 megs of unicode-looking data that I have to believe is the HFS+ "Journal" part of a journaling file system.
.journal_info_block appears to be an empty file.
.fseventsd contains only a few tiny files that appear to be the the heads of .plists.
Anyway.
The HFS+ folder looks like this:
dir_2243617          dir_2255418          dir_2283556          dir_2383839          dir_880892

Each of these directories seems to contain a few files that I'd want to keep, and Stellar Phoenix tells me that it recovered a couple million files total. A bit of "light reading" into the HFS+ file system suggests that HFS+ uses these integer file descriptors instead of file names, and that the file names are stored elsewhere?
I've looked around on the web for anybody who's had a similar problem and have yet to find anything. It'd be really neat if all you had to do was create a new .sparsebundle and throw all the files into it, but I somehow doubt that'd work...
I'm really concerned that I can't put humpty dumpty back together again at all.
If I can't, what would be the next best thing? I've considered copying the files back to the drive and letting Spotlight chew on them. Eventually, I would probably be able to find the most important files on the drive. But I would prefer something more user friendly than that.
Oh, and feel free to suggest your favorite online backup solution.
Thanks for reading,

How to view all files stored in iCloud

How do I view all my files stored on iCloud?
I purchased additional iCloud memory space , backed up my iPhone then deleted videos from my iPhone to free up space.
Now I would like to retrieve a home video. Where/how do I see what's saved in my iCloud account?

You can't use iCloud to free up space on your phone like that. Videos are only stored in the iCloud backup, and can only be accessed by restoring the backup to your phone. However, if you delete the videos from your phone and continue to back up, the backup containing the deleted videos will be overwritten by one that doesn't and they will be lost. Hopefully haven't backed up your phone since you deleted these videos. If not, restore the backup to your phone to recover them.
In the future, import your camera roll photos and videos to you computer using your usb cable as explained here: http://support.apple.com/kb/HT4083. Then you can delete them from your phone and sync them back later if you ever want to.

How can recover files from a HD with damaged "permissions"

I had a second HD drive installed on my macbook pro with my iPhoto library and other files stored and, for my own stupid reasons, which had not been backed up for over 3 months. It was actually the original Toshiba boot drive that came with the machine. I replaced it with an SSD over 18 month ago no problems.
The drive now has permission errors which the OS X disk utility cannot repair. I cannot copy the iPhoto library to my main drive and half way through the copying process a get an "error reading disk" message. I cannot open the iPhoto library using iPhoto either.
I decided to remove the HD and replace with a new larger and faster drive as the existing one was probably over 5 years old. No problems with the new drive whatsoever.
I am tried connecting the faulty drive using a USB interface and running the disk repair utility - no difference. Although I was able to copy smaller files other than the iPhoto Library.
I am running 10.10.1.
Is there anyway or any 3rd party app that can recover the iPhoto library? I don't want to waste money buying one of these so called great apps that ends up doing no better than the standard OS X. I read somewhere they all use the same code within OS X to repair anyway!
Ideas appreciated. The iPhoto libabry has my daughters 2nd birthday photos on it and our last holiday therefore I am in big trouble.

Try to to open the iPhoto Lib (right click) and Show Package Contents. Go to the the Masters folder (it must be organized by date folders), choose an image or folder and see if you can copy instead of the iPhoto Lib.

Com.apple.Preview and mf_refimg folders in trash (recovered files) lately

Hi,
Lately I am seeing a recovered files folder in the trash with a bunch of Preview folders titled "com.apple.Preview8909_2118585411 " and the like and also some titled "mf_refimg.29" and the like. All have pictures in them. The Preview folder has a bunch, if not all of the pics I've looked at with Preview lately (maybe yesterday's batch from the camera) and the mf_refimg folders have a graphic I used with Disc Cover, a CD/DVD cover app. Disc Cover is working fine as is Preview. No strange behavior noted in either app other than the OS thinking that Preview still has a pic open after I have closed that pic, which has been a sporadic Preview bug for awhile. All the pics appear to be copies of pics that are happily in the folders they started out in, elsewhere on my computer.
Why is it doing this? I have recently checked the drive using Disk Utility from my install CDs and nothing has been found to be wrong. I had a kernal panic a few days ago but Disk Utility has checked things since and found nothing wrong. (The kernal panic was due to my trying to startup from an external Firewire drive that had 10.4.8 on it. That disk has since been erased and reformatted with no system on it, just the driver so it will appear on my desktop when connected. I haven't used that drive since checking my Powerbook disk with Disk Utility.)
Thanks for any help.
Cheers,
John L

Just to add a bit to what Malcolm said--many programs keep temporary files. In Preview's case you'll notice that there is a "Revert" item in the File menu, so if you make changes and then change your mind it can recover the the original. The temp files for Preview are stored in this hidden directory:
"/private/var/tmp/folders.501/TemporaryItems"
Programs are supposed to clean up after themselves when they quit, invisibly getting rid of their temp files, but some programs fail to do this. Preview USED to but no longer does (one of a number of things that got goofed up in Preview when they re-wrote it). When that happens the system itself will do the clean-up next time you restart, and place the temp files into the Recovered Items folder which it deposits in the Trash. Another Apple program that fails to delete its temp files when it quits is SoundTrack Pro (and its garbage can be very large files). Since programs are supposed to automatically get rid of this stuff, when they don't the system assumes the program crashed and that you might want the things back, so puts them in a folder in the Trash so you can sort through and decide if you need or can use them.

Is it possible to recover files after reinstalling my whole Mac OS X?

I recently reinstalled my whole Mac OS X in my new iMac. But I realized I forgot to backup some files (my Pictures folder!).
Is there a way I can recover those files? When I reinstalled the software (using the DVD's the iMac came with) I used the option erase and install (I don't remember exactly what it said but it was the complete reinstallation option.
Thank you.

It could be - remember that a folder is really just a special kind of file. The files within it are just additional files, linked to it as contents in the file allocation table. And all of them are not necessarily kept as a discreet contiguous chunk of data on the hard disc. So yes, it is possible that the folder itself is fine, but the files within it are not.
Or, as mentioned, it could be something else, like permissions, or a corrupted iPhoto database, or who knows?
Did you look at the DR3 FAQ? Does it make any sense to you, given whatever was displayed while the recovery software was running?
DR3 online FAQ entry:
I recovered files, but they won’t open. What’s wrong?
The answer to this question depends on whether you’re talking about files recovered from under the “CBR” folder, or other ones.
Files recovered by catalog (i.e. Not from the CBR folder)
It's normal for a small percentage of recovered files to be bad. But if you have checked a number of them and none of them are good, then chances are that they were recovered with wrong ABL setting. Pick out a few files to use as test files, and go back and select a different ABL choice (Expert>Allocation Blocks Layout..menu) and recover and test those few. If you find an ABL setting that gives good results on those files, re-do your big recovery with that setting. For more information, read the material on Allocation Block Layout in section 8.2.1 of the Data Rescue 3 Users Guide.
Files recovered by content (i.e. from the CBR folder)
It's also normal for a small percentage of these files to be bad. If the original file was fragmented (not stored on disk in consecutive blocks), then it can not be properly recovered by content. In most normal situations, most files on a user's disk will not be fragmented. Typical fragmentation rates for files tend to be just a few percent.
Note: The ABL setting plays No role in recovering files under the CBR folder.

Recovered files gone after restarting Muse after Update

Muse quit unexpectedly while I was working on several websites in that were in recovery mode. When I restarted Muse, it told me that an update was available. After restarting Muse after the update, it did not attempt to recover the files that I was working on. Are the changes that I made lost forever, or can I find them stored somewhere on my computer? I have a current time machine back up. Will that be helpful?

Muse does not recover files from older versions of Muse.
The Muse team recommends you save any work in progress before updating Muse to a new version.
If you have a timemachine backup of the recovery files and the unsaved changes are important to you, you should be able to recover them by doing the following:
1. Look for the Muse recovery files in your time machine backup. They should be here:
/Users/your-user-name/Library/Preferences/AdobeMuse/Local Store/Recovery
Restore that folder to just before you did the update to Muse version 6.
2. Uninstall/delete Muse 6
3. Install Muse version 5.0 from here: http://labsdownload.adobe.com/pub/adobemuse/builds/muse_5-0_update_mac.dmg
4. Launch Muse version 5. Do not update. It should recover your files.
5. Save your file(s)
6. quit Muse, launch again, update to version 6.

Numbers generates recovered files on bootup

Does anyone else experience this?
Whenever I have used Numbers '09, the next time I do a cold bootup (power down, cold startup) in the trash I find recovered files, always the same one. Like this actual example:
Trash
} Recovered files (folder)
} com.apple.iWork.Numbers183_SFED_2960572041
} style-thumbail-Basic.tiff
Always the file "style-thumbail-Basic.tiff". Pages also always produces a similar error; I don't just now recall the file it generates.
Does anyone else experience this? Yes I've reported it to Apple. Yes I've repaired permissions. Yes I've checked for disk errors with Disk Utility.
It doesn't really seem to be a problem, other than the fact that there are recovered files means some kind of error has occurred.

I identified these 'recovered files' linked to Numbers.
They are the thumbnails of recents documents which are no longer available.
On my machine, I sat the number of recents documents to twenty.
On every morning, during the startup process, the preferences file is replace by a script which I wrote, by a clean one designed to get rid of possible corruption.
As the stored thumbnails are no longer matching the 'recent documents' described in the installed prefs file, they are dropped and I retrieve them in the trash.
So, don't worry.
The only surprising feature is that they appear as 'Recovered'

The same recovered files in the trash, every morning

I'm accustomed to Mac OS X's practice of placing potentially important files in a "Recovered Files" folder in the Trash after a reboot if, say, an application crashes. But I'm getting annoyed by my computer's habit of placing a set of files in such a folder every single time it's shut down. The files all look like remnants of an Asian-language font set. Here are the most recent names:
#Junggothic.dfontATS_493169727169
#Junggothic.dfontATS_17722080525333
#Junggothic.dfontATS_3922-125658874
#Shinmyoungjo.dfontATS_493169492902
#Shinmyoungjo.dfontATS_17722080452720
#Shinmyoungjo.dfontATS_3922-126354157
#Taegraphic.dfontATS_493168710633
#Taegraphic.dfontATS_17722080055722
#Taegraphic.dfontATS_3922-128251752
I do not use any Asian-language input methods whatsoever, nor do I visit Asian-language websites with any regularity. But I can confirm that all three of these fonts:
#Junggothic.dfont
#Shinmyoungjo.dfont
#Taegraphic.dfont
... are present in ~/Library/Fonts. Does anyone else also have them, and if so do you know what program may have installed them? Is the hash symbol supposed to be present in the name? I'm tempted just to trash them, but I'd prefer not to if they're regularly used by websites, etc.
Thanks!

Since they aren't installed by OS X or MS Office, then they were installed by some third-party software you installed.
The files in the Trash are actually cache files generated by the ATS = means either Apple or Adobe Type System. Probably the former. Most likely these result from the nightly cleanup scripts tossing unneeded cache files from the Type System.
If you don't use these fonts then track them down and remove them. If they aren't in one of the three Fonts folders normally used, then they could be Adobe fonts stored elsewhere on your computer. Use a utility like Easy Find - VersionTracker or MacUpdate - to search for them.

I downloaded a word file from an inbox mail (the mail app) onto my iPad2, where is this file stored? How can I delete it if it takes up space in my iPad? Any ideas??

I downloaded a word file from an inbox mail (the mail app) onto my iPad, where is this file stored? How can I delete it if it takes up space in my iPad? Any ideas??

Did you ever figure out what happened?
I had the same experience as you did, but in my case it was a big fat pdf that Mail insisted I had to download before I could view it. As happened with you, I saw the file actually downloading, and after a time I was able to view the pdf. It's been my assumption that the pdf is still somewhere on my iPad, but I have no idea where, nor how to delete it if it is still there.
Thanks.

2. How do i recover file which deleted from MAP drive...
Please help me to resolve this issue...
Kalpesh Chauhan

As to your first problem, I am not so familiar. But, as to the second problem, I think I can help.
In fact, I have ever also accidentally deleted my hard drive files. In order to re-access them, I have also posted my question in forums, just like you. Fortunately, after browsing many related answers and threads, I just know that a third
party data recovery program can be a good chance to go on.
So, I follow some instructions in these forums and select three drive recovery freeware to go on, including Recuva, iCare Data Recovery Free and TestDisk and so on.
Finally, I have restored all my needed data back successfully with these freeware.
So, I hope it will also help you out.
PS: Never forget to back up everything important on different hard drives or places in case of any similar data recovery problems in the future.
