Can we get someone from Tableau Engg to answer this? We are also looking for the same info as our business users are asking the same question.
It is currently not possible to restore part of a Tableau Server backup file (.tsbak). While it may be possible to extract specific workbooks from the .tsbak file with the workaround provided above by Graham, it is important to note that this is unsupported by Tableau and we are unable to troubleshoot any issues that may arise when using this method.
Hope this helps,
Absolutely Eric. I will re-emphasise... THIS IS NOT SUPPORTED BY TABLEAU!!!
What can be done, shouldn't necessarily be done.
