TIH2011 - File names

Dear all,

I don't have good knowledge of the English language why it's really hard for me to read all the articles in this forum. Therefore please excuse my eventually silly question(s).

I have been using TIH 2009 & 2010 for a year, since yesterday I use TIH 2011. The program took over the old backup tasks. But - I have some problems with the naming.

I use the following naming:

[Backup-Name]_xxx.tib
xxx stands for the automatic number which was added by TIH 2010

Example:
Incremental backup, full backup after 2 incremental backups

My_Documents_(2).tib
My_Documents_(2)2.tib
My_Documents_(2)3.tib
My_Documents_(3).tib
My_Documents_(3)2.tib
My_Documents_(3)3.tib
My_Documents_(4).tib
My_Documents_(4)2.tib
etc.

After the update the naming is:
My_Documents_(4)21.tib
My_Documents_(4)22.tib

What went wrong?
In the past I had the same problem sometimes after any failure of the backup task. I fixed it by opening the task and choosing the last backup of the task again. Afterwards the task went as expected. In 2011 this workaround is no longer possible as you can't choose an existing backup for the backup task.

Thank you so much for your help,
Christian
