The mysterious _v11.tib file access error.

Thanks Bruno for bring all these topics together.  Please drop a message to Ekaterina about this too and request she get one of the more senior Acronis Support folk to review both your support case and these forum topics where this has featured.

"This issue with the mysterious _v11.tib file access error keeps coming up. I'm starting a separate thread in order to help consolidate user experience with it as right now I see it coming up in a number of different threads.

My feeling is that it has nothing to do with NAS credentials, but rather is a program bug that occurs after some sequence of events which we've not been able to determine precisely as of yet."

Bruno,

I agree v11.tib error message is not related to network credentials.  It is related to TI being unable to access a backup file for any number of reasons.  I think that the v11 is an arbitrary number that TI gives the error.  I also think that the error occurs when TI determines or believes that the subject .tib file is already open or in use by another app such as Windows Explorer, another file browser type app such as an NAS web-UI management app, or an established network connection to the network share location of the subject file.

Kudos for doing the leg work to pull all related threads together on this error.  This should help in driving focus to the issue. 

As we have been looking at my situation in my thread here: https://forum.acronis.com/forum/acronis-true-image-2018-forum/backup-fa…

and you guys are suspicious I have the same issue I thought I should add the following.

I had TI 2016 working with a scheduled Differential backup task (Daily, full every 6 differentials, cleanup after 2 full cycles) and had zero issues with this bug. 

Installed TI 2018 with same backup system (new backup file not continuing old one) - will not commence backup.

Reinstalled as part of troubleshooting - still won't work.

Reinstalled TI 2016 - works immediately.

Reinstalled TI 2018 to troubleshoot more for support and help here - NOT working.

EDIT:

I found I can get a backup working to my NAS - only if I use an existing backup.

1. add existing backup (browse to \\192.168.0.3\   ...)

2. reconfigure 

3. backup .... and it works. Same settings as I normally use and my normal directories.

BrunoC, mgrobins, I have asked the Development Team to have a look into this issue, check the reports and all the information you've provided.

It is clear that it is hard to replicate the issue on demand and catch the problem in the program, but hopefully we will be able to get to the root cause and correct it.

Thank you!

Slava, another forum topic on this topic in the 2017 forums this morning:

See Unability to create a fresh backup task for a partition I previously had a task set up where another report of the _v11.tib is given.

Thank you Slava :).

I am attempting to get additional reports to the support team as well.... just having issues with no internet (tethered to 4g on my ph just now to message), and accessing your ftp site to upload.

Discussion on my own thread has led us toward Bonjour as the possible cause or link to issues I am facing.

It was mentioned TI 2016 used the printer element of Bonjour and TI 2018 is using a newer version and structured differently in its interface with bonjour.....
