Error "failed to read snapshot"

Thread needs solution

Hi

I'm getting hte "failed to read snapshot" error when I try to backup my computer. I had this issue before with Acronis 11 and it was resolved with an upgrade to Acronis 12 but now the problem has returned. The problem is I'm off abroad for 3 months next week and desperately need to get this backed up and working before I go.

Can anyone help?
thanks
Nancy :)

Sorry just to add - the full error messages says " Failed to read snapshot (0c10C45A) CRC error (0x100155).

It gives me the option to "ignore all" - if I do that will the back up still be successful?

thanks :)

A couple of questions for you. What version of Windows are you using? What version of ATIH 2012 are you using? Sounds like you may have some errors on your disk. You may want to check both the source and target disks for errors.

HI there

windows version 7 home premium 64 bit
Acronis 12 update 2 build 7119

the target disc is a brand new WD passport 2tb portable drive - never used.

the source disc was replaced by Sony only 6 months ago after a hard disk failure. How would I go about checking for errors safely?

thanks

Click on the Start button, click Computer, right click on the drive to test for errors, click on Properties, click on the Tools tab, under Error Checking, select Check Now. Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors. If your are checking your system drive, Windows will prompt you to schedule this check the next time Windows starts up. Be sure to tell it to do so. Then restart your system. Windows will scan the drive for errors, and do a surface scan to detect possible bad blocks before booting. This may take some time.Windows will correct errors it finds. See the following Microsoft website: http://windows.microsoft.com/en-US/windows7/Check-a-drive-for-errors. Also you can use the hard disk drive manufacturers drive test utility. You would need to know the brand of hard drive installed in your Sony system. Then go to the manufacturers website and download the appropriate Windows drive testing software for your drive. Be sure to only run non-destructive testing if doing this. Also if you are using the WD passport on a USB 3 port, try connecting it to a USB 2 port and test it there as well. Do not connect the external USB drive to a hub, directly connect it to the computer. You could also try using a different USB port.

Hi
When I go in to properties on my computer there is no tools tab and I can't seem to find "error checking". Any idea where it is or what it might be under?

sorry
thanks

aha! got it working now! will try that and try the back up again ...
fingers crossed! :)

You can try booting to the recovery disk and doing a backup. If that works, at least you will have a backup before you leave and you can continue to work on resolving the problems while using Acronis in Windows when you return.

In Acronis, you can make a bootable CD, DVD, or USB flash drive that can be used for recovery as well as backup. If you wish to use a flash drive to boot from, insert it now. Be sure you don't need anything on it, as it will be erased. Open Acronis and go to the Tools and Utilities Tab, then select Rescue Media Builder. When Rescue Media Builder opens, click Next. On the Rescue Media Contents Selection, click on the box at the top of the list. That will select all options for you. Then click next. You will then be on the Bootable Media Options screen, click Next. You will then be on the Bootable Type Media Selection screen. At this point you will be presented with choices of which type of media you wish to create. I usually choose the CD/DVD drive to make my first Rescue Media, and then run Rescue Media Builder again and make a USB flash Rescue Media as well. Both work the same. Continuing, for CD/DVD creatition, select your CD/DVD drive in the list, then click Next. You will then see a summary screen of the options you have selected. If these are correct, click Proceed, if not select back until you get to the options you wish to change, and the continue from there. When you press proceed, the Acronis Rescue Media Builder will create a bootable CD, DVD, or USB flash drive. With this disk/drive, you then can restart your computer and boot to the CD/DVD or USB flash drive, and run Acronis True Image Home from this disk/drive, bypassing your installed copy of Windows, which could be your problem. To boot to the CD/DVD or USB flash drive, you must set your computer's BISO/Setup program to boot the CD/DVD drive or the USB flash drive first. Alternatively, if your computer prompts you when you turn it on with a "boot device selection option", you could press the appropriate ket to bring up a list of devices that your computer can boot to. You then would select either your CD/DVD drive for the CD/DVD, or your USB flash drive to boot to it. After booting into the Acronis Recovery Media, you would then select Backup - My Disks, and then choose your system's internal hard disk drive(s) as the source, and the external USB backup drive as your destination.

Nancy,

Definitely follow Jame's excellent guidance to use the recovery CD. You need to be able to do that to make the backups really useful at recovery time anyway.

Wrt to your issue, you might want to simply uninstall, reboot, and reinstall ATI. Let us know if the problem doesn't go away.

Thank you all

I've spoken to the live chat team - they suggested using clean up utility and then reinstalling acronis - which I did. I still have the same problem.

I've used bootable media to create a recovery DVD - but just to ask - is that actually a back up of the entire system and all the files or not? I'm just worried about whether or not I've actually got a back up while they look in to this issue..

They seem to think it's a driver conflict? but that's not what they said last time it happened so I don't know!
:)

Nancy,

When you create the bootable media, you don't backup. You are just creating a disk that you can boot your computer on and that runs a version of ATI outside Windows (Windows is not running). You can backup and restore using the ATI version.

Hi

sorry I'm not sure I understand - so if I want to create a back up can I do that from the bootable media? The acronis live chat guy told me before I did the clean up utility that I needed to back up and that using the bootable media creation tool would do this so he was obviously mistaken... I can't back up through ATI as I'm getting the snapshot error...

sorry for being dim! :)

Yes, you can create a backup using the bootable media. First you have to create the media. YOu can do this from ATI running in Windows, or you can download the bootable ISO from your account on Acronis.com, after you have registered your serial number there. You would then burn the ISO *as an ISO* (not a simple file copy to the CD) on a blank CD. You would then set up the BIOS of your computer to boot on a CD, the computer would boot and you would see ATI running from the CD. Note that drive letters displayed by ATI on the CD are not the same as in Windows. Pay extra attention to disk labels to recognize them.
Do a backup that includes everything on the drive where ATI is installed.

Nancy,
I'm sorry you are still having errors during your backup. One thing to try is to backup one partition at a time, to see which one is giving you the error. Do this from the bootable CD to help with any Windows problems. If you need help with this procedure, please post and more instructions can be given. I hope you can track this down, and get it resolved.

Nancy,

This really points to a disk issue.

Did you do http://windows.microsoft.com/en-US/windows7/Check-a-drive-for-errors for the disk that you are trying to back up?

If yes, do you have a CD from your disk manufacturer to diagnose the disk? Sometimes, the Windows tool doesn't see issues that manufacturer's or ATI tools can find...

Thanks

I've tried that and nothing came up.

I don't have a CD from Sony though this hard drive was replaced (after failure) about 6 months ago or so....

The latest acronis live chat agent told me I can ignore the snapshot error and complete the back up and it will work - it will just mean that when I restore it the "bad sectors" on the hard drive will be restored too... does this sound likely? sensible?

:)

Well, it the backup can complete normally despite the error message, there is maybe a bug that Acronis is aware of and doesn't jeopardize the backup. In the past, not being able to read the snapshot was preventing any backup to be completed.

Can you complete a backup in your case despite the error?

I'm trying now - it's about 60% done so fingers crossed!

I wish I knew more! the bad sectors on the hard drive worry me!

A few bad sectors are OK. When bad sectors increase, then it is a bad sign.

THank you :)
the weird thing is the chkdisc didn't indicate any errors but maybe it's just not picking them up.. so far I'm not that impressed with sony - my old toshiba was much better!

I'll see how this back up goes and will try restoring it to an external hard drive and take it from there... :)
