Differential Backup Failure - TI9

Hello
I am getting very frustrated with True Image.
My problem is that a monthly full backup works fine, but that the daily differential backup
(a) sometimes seems to revert to an incremental backup!
(b) works for a few days and then starts failing - I have no idea why
(c) more recently, seems to fail because of pretty harmless looking files or folders in "My Documents" such as a folder full of pictures

The only thing that has sometimes worked is that I've realised my backup drive is full, hence TI failing - so I've deleted a few files and that's done the business. (Though isn't TI supposed to be able to detect that and start replacing the older files?)

But now I'm foxed as to the problem.

PLUS (moan, moan) I've never really understood why you have to choose the same file or archive name (again, never understood the difference) for a scheduled differential backup as the scheduled full backup.

Now, buying online means that you don't get the manual and maybe I should have looked at that much more closely. But the programme just doesn't seem very intuitive - or maybe it's just me...

Cheers for any help people can offer me!

 

What Version of TI 9 are you using?
Here is the link to the User Guide http://download.acronis.com/pdf/TrueImage9.0_ug.en.pdf.

 

Thanks for your attention.

The latest build as downloaded from Acronis over the weekend - sorry, can't remember the number (am currently reinstalling as per forum advice).

 

Please Acronis (or anyone) - I don't understand why I can't do differential backups any longer. Certain files seem to cause the back up problems:
e.g.
Failed to backup file or folder 'C:\Documents and Settings\All Users\Documents\My Videos\trailers'.
Error reading the file. (0x40001)
Tag = 0x61F1883FE50B0A2D
(0x1003EB)
Tag = 0x14181C22EF45AC22: Retry/Ignore/Cancel
Why should certain files do this? It's never happened before!

 

Please help me!

 

PLEASE ANYONE!

 

I suggest you open a formal support request here https://www.wilderssecurity.com/showthread.php?t=55317.

 

Exactly the same problem here, many months later with TI10...

Not sure if anyone has solved the problem, but I'd be grateful for advice...

Random "read errors" as above, usually on picture or media folders...

Used to worked brilliantly - and I suspect an MS update somewhere "broke something", but I'm stumped as to what and how... and have no proper backups to go back to unfortunately...

 

I have uninstalled Media Player 11 which I suspected of being at fault.

I also uninstalled TI10.0 from Control Panel - completely reinstalled.

Ran chkdsk c: /r on the drive in question - no errors...

And yet still the backup fails on random files/folders in the "My Pictures" directory with the same error number as above...

I'm stumped - I can ignore the error and sometimes it's only 1 file that has a problem - sometimes it's 10 files...

This is extremely frustrating - the product worked flawlessly for months... now I can't get a proper backup from the product.

FYI - backing up from boot CD works fine - but this is not an option for me as the machine needs to be running most times...

Any help/advice appreciated. I've logged a case with Acronis, but no joy yet on a resolution.

If you're running McAfee, try turning off the "Phishing Filter" - worked for me. See my later post for details.

Otherwise, try disabling firewall/anti-virus software to see if that is the issue then through "trial and error" try to work out which piece is causing the problem.

Painful process, but paid dividends for me...

Good luck...

 

Many thanks for your input Aussie. It's good to know that I'm not the only one! I shall give your ideas a try.

Same Problem here, we are running TI9 Enterprise Server (german) on Win2k3 x64 (english). Every night a different File that causes the Backup to hang... Has anyone more ideas? BTW: We don't have a local Firewall or Virus-Scan running...

 

And this is exactly why I won't be purchasing any TI server-class products. Putting TI on an Exchange server is like playing Russian Roulette. From all the posts here on the forum (yes, forms like this have only bad things to say), I gathered TI is not 100% stable in an Enterprise environment. I have personally seen TI hang (multiple times) on a MS SBS 2003 server that required a server reboot to get the backup tool running again. In addition, if/when TI does fail, you have to manually edit the registry to completely remove the application. I find this totally unacceptable for an enterprise-class product.

My "voting" dollars will be spent elsewhere...

 

Hello drl13,

Thank you for choosing Acronis Disk Backup Software.

We are sorry for the delayed response.

Could you please clarify us some points, so we could give you a solution?

- How do you figure that differential backups revert to incremental?

- Was the issue with failing after several days related to lack of space on the backup drive?

Note that Acronis True Image 9.0 Home is able to monitor the free space and delete the older files if needed in case you set up and back up to Acronis Secure Zone. For detailed instructions on how to do that refer to chapter 3.3 of Acronis True Image 9.0 User's Guide. Also note that a new version of Acronis True Image, Acronis True Image 10.0 Home, provides a new method to store and monitor backups - Backup Location. You can learn more about it at Acronis True Image 10.0 Home backup management features page. I would also recommend that you have a look at this previous thread describing how to use backup location.

The requirement of choosing the full backup as a target for making differential backup derives from the nature of the latter. The differential backup, as its name implies, is a log of changes made to the disk structure between the time of full backup and the time of making differential one. Therefore, Acronis True Image needs to compare the full backup with current system state. You can also take a look at this article describing the difference between incremental and differential image archives.

Please do the following to fix the failures of backing up files in your “My Documents” folder:

- Download the latest SnapAPI archive file from http://download.acronis.com/support/SnapAPI_l_s_e.zip;
- Unpack the archive;
- Install the unpacked MSI package and check if that fixes the problem.

If the problem persists, please do the following to collect additional information that will help us to investigate this issue thoroughly and provide you with a possible workaround:

- Please replace C:\WINDOWS\system32\snapapi.dll with the one from the downloaded SnapAPI archive;
- Reproduce the problem;
- Get the log file without closing any application windows (including the error message windows if there are any). The log file will be created at C:\ . The name of the log file will be snapapi [date-time].log.

Please make a screen shot of the Device Tree application the way described in this previous post.

Please also create Acronis Report and Windows System Information as it is described in Acronis Help Post.

Could you also collect the program log you mentioned? In order to do so please do the following:

- run the program;
- select Show log on the toolbar or from the Tools menu;
- select the log with error messages;
- click "Save the log entry to file" (the diskette icon).

Then submit a request for technical support. Attach all the collected files and information to your request along with the step-by-step description of the actions taken before the problem appears and the link to this thread. We will investigate the problem and try to provide you with a solution.

Thank you.
