ATIH 2012 archieve corrupt message

Thread needs solution

I create an backup image of of WIN 7 (64x) installed on 250G SSD with ATIH 2012 (latest buildl) on a local drive (D) and add incremental images each day.  I validate the total image with each addition and everything is fine. When the total image reaches 25 images I would like to move (copy and paste) all the incremental images to a USB3 drive. The problem is when I complete moving the files (copy and paste) and run the ATIH validate test ATIH reports the image is corrupt. What am I doing wrong?.

The validation process is very sensitive and any minute change in the data is enough to make it fail. We have seen this several times on this forum. Some times, it fails after a copy even if the files have zero change (as measured by chksum operations). In these cases, validation can also fail because of hardware issues (usb, memory, disk I/O), or because of corruption between the database and the actual files.
The point is, it is not unheard of that copying "corrupts" the archive enough to prevent a successful validation.

Once an archive is deemed corrupt, it lessens considerably your level of confidence that you can restore, but doesn't make it null.

Try to validate from the recovery CD. Try to recover some files from the backup. Also, try mounting the image within Windows. If these operations fail, then it is likely that your chain is corrupt. You'd have to start a new chain/backup task in a new destination folder to start afresh.

In terms of backup strategy, if you create up to 25 incrementals, that seems a lot. The rule of thumb though is that your oldest validated full backup should never become so old that you would not consider going back to it.

You mention moving only the incremental which are worthless without the full and would give you a corrupt backup error if full not included in the copy.

You might also want to user a better method of copying such as using the free Replicator which offers more feature and error checking.

Thankyou very much for your help and suggestions! My problem is solved.
Let me clarify by adding the details I forgot to include.

I was in a system build and creating backups on a daily basis. At this point I was never sure how far back I may have to restore to recover. The full backup was included with the incremental backups. Each backup was verified. Normally I would not have that many incremental backups. I did not discover I had a problem until I moved the archieves to a USB3 drive and the Verify failed. I went back and checked another archieve that I copied to another hard drive and that failed also. I checked the same archives with the Recovery Disk and they also failed.
Today I ran one last check. I created a new archive with a full backup and 3 incrementals. I checked the acrhieve with Acronis and it passed. I copied the archive with Win 7 copy and Karenware to a USB3 drive. I checked each archive with Acronis and the archieve copied with Karenware passed and the archive copied with Win 7 failed. I also checked both archives with the Recovery Disk and confrimed the prior results, the archive copied with Karenware was fine and the archive copied with Win 7 was corrupt.

It would ne nice if Acronis provided a copy program that the user can use to safely copy and move the archieve. Does the Acronis 'Move Archive' move the archive without corruption? Does ATIH 2013 have the same problem with Copy?

Thanks again for your help.

Ed,
Glad you found a workable solution.
The move option does not actually move the file--just changes the location to a different folder or drive for the next backups.
If you were to use the original for a restore, you would need to point manually TrueImage to the location of the original files.

The problem with the copy is not an Acronis problem. It relates to the hardware of the two disks involved and the transfer speeds.

Karen's program is much more sophisticated and does more error checking and so notifies of any errors. Replicator has a log file which can and should be reviewed.

GroverH,

I based my Move question on the results of a Acronis Knowledgebase search  I ran 'Moving archives with Acronis 2012" . The search came up with came up with  http://kb.acronis.com/content/3886 . I realize it referances ATIH 2010 but I 'assumed', since there was no disclaimers ,it still applied. The article also refers to using windows explorer as a method of moving archives.  Since this clearly does not apply to ATIH 2012, and is critically important, I believe it should have stated so in the ATIH 2012 specs. Very confusing.

I tried the Move option and it works differently then you suggested: "The move option does not actually move the file--just changes the location to a different folder or drive for the next backups." When I choose the "Move" option Acronis posted a list of possible locations ie drives and folders. When I chose a folder and confirmed the choice Acronis copied all the backups from the current folder to the new folder and, in this case on the USB drive, deleted the original files and updated the backup panel data. I validated the backup and the process looks good.

I now have 2 methods for moving the archive that both work, the Replicator and Acronis Move. Thankyou for your help.

Thank you for the update and the information as to how the move worked.
