Error "An error occurred on the server generating the backup (..)" When Generating Backup on Tableau Server

Issue

Creating a backup with standard command: tsm maintenance backup -f ts_backup -d fails during backup of database and the following error message is returned:

"An error occurred on the server generating the backup. See /home/user/./tableau/tsm/tsm.log for more information"

"66% - Backing up database failed: 'org.apache.thrift.TApplicationException: Internal error processing completeStartDatabase'"

However, the backup completes successfully when adding the -k option to bypass the database integrity check.

Environment

Tableau Server 10.5.0 - 10.5.4, 2018.1.0 - 2018.1.1
LINUX RHEL / CentOS 7

Resolution

Option 1

As a Tableau Server Administrator, upgrade to Tableau Server 2018.1.2, 10.5.5 or a newer version. Click here for downloads of current and previous versions of Tableau Server: Tableau Server Downloads and Release Notes. For more information on current releases, see Upgrade Tableau Server and Server Upgrade.

Option 2

As a workaround, disable SSL repository by running the following commands in the order listed below:

tsm security repository-ssl disable
tsm pending-changes apply
tsm maintenance backup -f ts_backup -d

Cause

For TSM to have have access to the repository for backup, ssl/encryption needs to be disabled.

Additional Information

The backup completes successfully when adding the -k option to bypass the database integrity check.
