Backup fails: message "The end of the file has been reached" raised on a Mozilla Thunderbird folder
Hello dear Forum users,
I bought Acronis True Image 2018 last year in September, and had no problems but since +/- 2 months one of my backups fails for an "unknown error" reason.
Using the MVP tool I got a log file of the error (attached file, rename it to extention ".odt"). The error message is "The end of the file has been reached", raised while backing up a folder managed by Mozilla Thunderbird (on drive "G:\" in my system). This did not happened before.
Support suggested me... to exclude the "archive\data_reader.cpp:562" folder from my backup. I was surprised to read that, since:
- it is a file, not a folder;
- it is a C++ source file of Acronis True Image software!! The complete path appears in the log file;
- this file is part of a call stack trace dump generated by Acronis True Image, nothing to do with my backup;
I then try this forum to get some more help... I don't know if the attached log file contains sufficient information, if needed I can try to give additional one.
Thank you for your suggestions and help!

Phillipe, welcome to these User Forums.
The log data shows that the problem file (folder) in your Thunderbird folder path is as below in bold:
| error 0x40003
| line: 0xce542e14da2039bb
| file: c:\bs_hudson\workspace\431\archive\backuper.cpp:412
| function: `anonymous-namespace'::BackuperHelper::ProcessTraverser
| line: 0xce542e14da2039bb; c:\bs_hudson\workspace\431\archive\backuper.cpp:412; `anonymous-namespace'::BackuperHelper::ProcessTraverser
| Path: G:/Thunderbird/Mail/Local Folder/2. ACCOUNTS.sbd
| $module: ti_demon_vs_12510
2.ACCOUNTS.sbd represents a folder within your Thunderbird Local Folders listing and it may be that there is an email message in this folder that is contributing to the problem?
Hello Steve,
Indeed everytime the problem arises it's somewhere under the "2.ACCOUNTS.sdb" folder. Sometimes it's one folder deeper.
I did a "repair" within Mozilla Thunderbird on the folders listed by the MVP error logs, Thunderbird itself can read emails in those folders. But Acronis True Image still fails doing an incremental version, for the "end of file" reason. Full backup works, though.
In my understanding, the stack trace information of the log file should help people maintaining the source code to go further... They have function names, lines numbers, error codes.
And why does it happen since 2 months, that's also a question!
Thanks anyway for your reply!

Philippe, I suspect that this may come down to a timing issue, i.e. that ATI tries to backup the file or folder when Thunderbird may also be wanting to access the same?
It may be worth checking your backup task settings on the Advanced options page as below to see if you are using the VSS without writers option?
It may also be worth running the Acronis VSS Doctor tool to ensure you have no VSS issues at play here? Link in my signature.
Steve,
My current setting for this backup is "VSS without writers".
I've downloaded and run the "Acronis VSS Doctor" program you mention, and it's strange: all checks are ok except the "VSS Writers Status" one, but the details of this check says "Failed to collect VSS writers status", with a "System.Exception" raised by "vssadmin"...
(messages are partly in english, partly in french - I'm Belgian. "Stable" is the same as in english and "Aucune erreur" mean "No error")
===========================================================
VSS Writers Status
Status: Error
Description: Failed to collect VSS writers status

<all other sections have the same status "Stable" and "Aucune erreur">
Looking further on Internet, I see that "vssadmin" is a MS command for managing Shadow Copy Volumes on Windows, which as far as I understand is useful to backup programs. I launched "vssadmin list writers" in an admin command prompt and it returns the same list as above, with all statuses ok and no errors!
I tried to change the size of the shadow storage on the drive "G:\", but this does not help. Incremental backup still stops for the same reason, in the same folder.
Curious that Acronis VSS Doctor program says it can't get the VSS Writers Statuses, but actually shows them... and declare it's in error...
Out of ideas as of now, but if you think of something else I could do I'll be glad to try!
Thank you again,
Philippe
Philippe, I have attached of the VSS Doctor report from my own system in case you wish to compare with your own.
The other option here would be to try using a different snapshot option instead of VSS without writers, i.e. Acronis snapshot which is the method used in older versions of ATI before Acronis switched to using VSS. This may help eliminate this as a VSS error.
One further suggestion, if you use Windows Fast Start where your computer is put into a hybrid sleep state instead of truly being shutdown, then try doing a Restart of Windows which does force a full shutdown and restart. You can check how long it has been since you did a full restart of the computer by opening the Windows Task Manager and looking at the Performance tab where Up time is shown.
Steve,
I dont use FastStart, because it causes problems when dual booting to Ubuntu and trying to mount Windows NTFS disks. I always do a full shutdown with a specific batch script calling the "shutdown.exe" command with appropriate flags. So no hybrid or sleep state.
I have changed the writers to "Acronis Snapshot", the problem is still there. I reverted to "VSS" setting.
Then I tried this inside Mozilla Thunderbird:
- create a new folder;
- move everything from the "2.ACCOUNTS" folder to it;
- delete the "2.ACCOUNTS" folder.
I created a full backup first (this always works), then send a small test email to myself, then call Acronis True Image backup again. It has correctly created an incremental version...
So it seems the problem is gone. I will watch for the next incremental backup task, in a week.
Too bad Acronis Support couldn't investigate very much (they gave me an incorrect advice, about one of their source code files!), and that the logs did not say enough about the real problem. The error code being unknown from the Acronis KB... This should not happen in my opinion, source code generates exceptions and errors, that should each be documented - idealy.
Many thanks for all your advices and suggestions, I'll come back here if something goes wrong again.
Have a nice day,
Philippe
Thanks for the update Philippe, hope all continues to be ok with no more strange problems like this one!
