Repair a corrupted TIB file

There are no tools for repairing a corrupted TIB file. However, there are cases where a backup is reported to be corrupt and actually isn't. Can you be more specific on the problem?

Opening the backup with a newer version of TI can sometimes help. You would have to try it to see.

I've done a backup of a damaged HD with bad sectors, but cannot recover, because I get a message that TIB file is corrupt.

Hello Chris and Mudcrab,

Thank you for your messages and your kind help is appreciated Mudcrab.

Chris, I will do my best to help you with this problem.

I would recommend to go through this troubleshooting guide that we have for corrupt backup issues.

If you need additional help, please let me know.

Thank you.

Well, I'm having the same issues big time. Several tib files all report corrupt even though all were validated after backup. It's approaching the stage where TrueImage will have to be abandoned because of unreliability.

You provided us no information. It's possible that your backups are fine, but some other issue is causing ATI to report corruption. Where are the backups stored? How is that drive connected? Have backups been moved? Have you checked the disk for errors? etc.

seoras,

Before assuming the backup files are corrupt, try to do the validation while booted to the Acronis Rescue Media.

Well, I did manage to resolve the issue. It seems that the recovery disc I was using was incompatible. When I reverted to an older verion, the file validated and recovered perfectly. Of course, that was a relief, but just what do Acronis think they are doing putting out erroneous and misleading 'corrupted' error messages? Corrupted it was not, incompatible it was. Surely they can indicate this to the user and advise which version is needed and where to get it. And they should devise a repair tool like Micosoft has for Outlook inbox files. Acronis's shoulder-shrugging, sloppy attitude hardly befits a serious software company. They really need to get a grip and encourage users to actually want to use the software - reliability is all, and losing data is just not acceptable to those who have placed their trust i the software.

Must do better. Much better.

Even worse here : my backup file was in a hidden foler and had the hidden attribute switched on itself... Well, when i tried to recover, i got the "corrupted" messagebox too. This is nothing else but sloppy work, indeed.

It does seem to me that it would be reasonable for Acronis to include an identifier within each .tib file that indicates what version/build of ATI was responsible for its creation.

Or maybe this is already detectable somehow?

I have an incremental backup file in the middle of 6 months of backup that must be corrupt, because from that date forward I can't see ANY files, but I can restore anything from before that date. How do I restore from dates after... what I assume is a corrupt file? I've done the copy to local drive and I've just copied the entire series to a different PC and installed True Image 2013 Trial. I get the same result using TI2013, before okay, after... not so much. Originally created with True Image Workstation 9.1.

James,

Each of the incremental backup files in the version chain (backup set) are based on the previous incremental backup file. If there is corruption in one of the incremental backup files, all of the following backup files will no longer be able to be used for recovery.
You should run a validation of the backup from both Acronis running from within Windows, and the Acronis Recue Media (bootable CD/DVD/USB Flash) to be sure the set of files is okay or corrupted. To salvage the remainder of the backup set, you would need to delete (from within Acronis) the incremental backup file that is corrupt, and all the following backup files created after that point.
There is no way to repair the version chain (other than to prune the corrupted backup file and any backup files following it), or to restore from the incremental backup files that are corrupt or follow the corrupted backup file.

I got error 0x9F2C53C72E8BCD1F .. after mounting robocopy did a marvel job .. and left just 1 file not recoverable .. why does this correction possibilty is not included .. "error, but just # files can not be retrieved" .. that would be a feature

How do Tib files get corrupted in the first place?

Dear Acronis team, please provide valid useful guides here on what to do. Otherwise your backup software is pointless. If everything is shrunk into one file, which can easily be corrupted, this is not backup, but rather are "data-destruction" software.

Please provide a tool to repair broken TIB files. Some parts of a 300 GB file can always break when copying etc. However that should mean that the remaining 99.999% of the data should still be fine. Just like on a normal harddisk ...

Cheers,

Michael

I got a severe problem with TIH 2014. My Home PC with Windows 7 Enterprise died from a motherboard problem. The hard disks, two 512 GB WD Drives installed in DELL 435 MT RAID using RAID 0, are still working absolutely fine. And I felt safe due to my regular incremental backup with TIH 2014 to a Synology DS211j RAID 1 system.

But here is the problem: TIH does not mount the image, because "it could not assign a drive letter to a partition". When just double-tapping on the image file most of the times it asks for a volume 2, or other volumes, that never existed. Sometimes, it will correctly show the folder hierarchy of the backup-ed disks, but then Windows Explorer will freeze forever. Trying to convert to VHD shows the same problems.

I scanned the forum but did not find any working solution so far.

I copied the tib-files to my internal HD with the same results. I tried all image files (there are 70 different increments), but neither of them works.

All the disks were connected to an Intel RAID controller which I do not have anymore. Thus, I am trying to retrieve the data with a disk enclosure using software such as ReclaimMe, RAID Reconstructor, or RAID Recovery with GetDataBack. So far, I did not succeed in restoring the RAID 0 configuration.

I am trying for days now to get my data back. And I am really frustrated. The last time when I had a disk problem, the TIH image was also corrupt. Which makes me think that I cannot trust TIH anymore.

Or is there a solution?

Try using older versions of TIH. In my experience, 'corrupt' and 'inster volume 'messages can occur when using a newer version to restore files created using an older version. I find it works reasonably well PROVIDED the same version is always used. I use it from a USB stick for both restoring and backup and never from Windows. If you get your data back maybe use Macrium Reflect Free editon

Good luck!

Thanks, @seoras.

I have used TIH 2014 to create the backup images. And I am using TIH 2014 to (try to) restore the data. Thus, it can't be a version compatibility problem.

Check out for MultiExtractor, on the software homepage is also article about data recovery from corrupted Acronis TrueImage Backup (TIB).

Sorry, but you are leaving things to chance if you only rely on a single disk image that was never validated to ensure its integrity. Same applies for incrementals.  Validation.  Acronis is trustworthy and works well, but an end users bears a certain level of responsibility in regards to protecting their data.

Examples are: create more than one disk image.  Back up to two or more locations,  keep one copy off site,  back up regularly and perform validation at least periodically to ensure the integrity of back ups as well as increasing the probability of successful recovery. 

A back up containing 70 incremental snap shots is an accident waiting to happen.  This is truly gambling and putting all of your eggs in one basket and hoping for the best.   

I am a proponent of RunTime Software who was intially based out of Las Vegas, but ultimately "retired" to Hawaii...  Get Data Back, RAID Reconstructor is great software.  A failed RAID 0 is difficult to recover from.  Fortunately, you are able to "try" the software against the failed array and recover up to 25 files (before purchase) if the array can be successfully rebuilt.  If it can't, you're only banging your head again a wall trying to piece together interleaved data from 2 or more disks.

I'd throw everything at it I could.  New versions of ATIH, old version, different builds of same version, whatever I could. 

There is no magic solution to this issue, except to avoid it.  Hopefully its a learning experience and will ensure you take steps to avoid data loss in the future. No one likes hearing this.  If the data is irrepalceable, then you take your disks to a professional Data Recovery Service and pay for recovery. Then ensure you don't allow it to happen again.  Its really that simple.    

My Acronis was suppose to back up my entire hard drive once a week. Error on my part for not checking the files. It said it was running but the files in my backup folder are every few weeks and all say they are corrupted. useless program

Hello Phil,

I'm sorry to know, that you have faced issues with Acronis True Image. Even if the backups are reported as corrupted, there still can be chances to retrieve the data. Please take a look at the suggestions listed in the following article. 

Thank you, 

I've given up on this - far too many backup files that will not open. It's just too unreliable. I now use Reflect which is slower but more reliable.

Acronis - what are you doing? The first objective of backup software is RELIABILITY!  The previous post indicates your product is anything but reliable. I see you are working hard to go OOB= out of business! Your fired!

Acronis, why would you complete a backup that fails upon restoration? If there is a problem with the original source files...shouldn't that be spotted/flagged during the backup process and NOT at the point of restoration... exactly what are you people thinking?

John, welcome to these User Forums.

Do you actually have a problem with a corrupted backup .tib file or are you just posting here to trigger some form of reaction from Acronis?

If you have a problem then please provide more information on what actual version/build of Acronis True Image you are using, what Windows OS etc and we will try to help you as best that we can bearing in mind that we too are just users like yourself.

If you are hoping to trigger a reaction from Acronis then please don't hold your breath as again, this is a user forum and Acronis are rare visitors, especially as this forum topic originated in 2011 some 6 years ago and was concerned with products which are now deemed to be obsolete and unsupported.

Damnation, a few years later, an acronis.

I can recover files from a corrupted archive (if it is not compressed)

there is such a multiextractor program it can work with TIB

but the problem is that there are signatures in the file that interfere with the correct restoration, for example, # 00FF0000FF # and there is a structure similar to them that can be seen as block ending marks (the tib file consists of blocks) and checksum marks.

I will no longer be on this forum if it is interesting to write on ramtamtager on the hosting of a very famous gmail provider.

I will be happy to help or if you help me

I'm posting this workaround because I searched all over for a solution and no luck.  I'm a home  I had a crucial large file and folder backup that appeared as corrupted to ATI 2020 and 2016.  Backup was split at 500 GB sections and there were 38 incrementals plus the main backup.  Backup was classic style .tib files not .tibx for each incremental.  Maybe the workaround will work for .tibx files too - I hope I never have to find out.

I successfully tried mounting the backup to restore files but that was a very slow process.  Thousands of files and for each file ATI prompted me to browse for the last backup file.  I used this method for a while, replying Enter to each prompt but I believe the incrementals are ignored doing it that way.  I can mount some of the incrementals but I don't know what's in them without opening each one and drilling down to each folder (the 37th incremental displays 37 folders to browse for files :(. )  The drilling down process is excruciating: it takes a long time and I repeatedly have to answer the same prompts either for the last main backup segment or the incremental file.

I tried the robocopy trick from one USB drive to another. After the copy ATI still told me the backup was corrupted or locked.  Here's the workaround that worked for me.  Use at your own risk and if you decide to try it work from a copy of the backup in case things go wrong; you don't want to make your original backups worse.

I found that I could trick ATI into adding the main backup  if I started the add an existing backup process before robocopy finished writing the partial backup file.  That is, in my backup folder I deleted the last main backup file and re-ran robocopy on that .tib file with the /z parameter (allows restarting a copy job after interruption).  The z parameter makes the destination file appear in Windows file explorer as if it's been fully copied, but it's only a partial copy until robocopy finishes.  In my case the last partial backup size is 260 GB.  After re-copying the file, after robocopy reported 90% complete, I used add existing backup which worked. The backup versions listed were different from my incrementals, though, so I still need a way to recover the incrementals.  But I am grateful to have the majority of the files back.

I wish I could email the files to Acronis and have them repair them for me.  Is that possible?  I'd pay a reasonable fee for such a service.

this service is available with a support subscription, but there is a gap in the ATI, there are no good engineers and it seems to me they do the same operation as you. if it doesn’t work "ask us it didn’t work, you have a corrupted archive there is not enough data")))

you can transfer a large array of data by uploading to FTP

Thanks very much. It seems like something simple and repairable like there’s an EOF line where ATI expects something else, like a line saying it’s the last file in the split archive. Thanks for the link to the tib reader but I’d need something more dumbed down. I don’t remember how to run shells / scripts and the like 😢. 

Is there a compiled set of tools available so I don't have to learn how to compile Typescript code from Github?  I have a depressed teenager here that lost a lot of files and the corrupt tib is preventing me from rescuing the files.

In my country there is a song "the world is not simple, it is not at all simple")) so there are no simple solutions, there is no ready compiled version either. it is possible to create a similar incremental archive and slip separate parts of the corrupted one there, if it is an incremental file-by-file archive 

re: the world is not simple, it is not at all simple

You know that's right 😉 😂.

Twenty years ago I could have figured it out in a day; not so easy nowadays ;).  The alternate approach you mentioned is interesting and maybe worth experimenting with.  Thanks for your time!

I had overlooked the post about MultiExtractor and am trying the demo.  It seems like it will do the trick

 yes, I tried it, but I had a whole archive with minimal compression and the photos were there, but they were broken, I had to do some work on recovering and analyzing the tib format, the multi-extractor creates an mxl file in the tempo folder or something similar there is a file name, its beginning and length, this data is enough to write a script to extract data
