TeamCity provides several ways to back up its data:

Restoring data from backup is performed using the maintainDB tool.

We strongly urge you to make the backup of TeamCity data before upgrading. Note that TeamCity server does not support downgrading.

Backing up Data

TeamCity allows backing up the following data:

The data to be backed up can be configured using the backup scope options when using the TeamCity Web UI or via additional parameters for the maintainDB command-line tool.

The following data is not included into backup:

The recommended approach is either to perform the backup process described under Manual Backup and Restore or run a backup from the web UI regularly (e.g. automated via REST API) with the "Basic" level - this will ensure backing up all important data except build artifacts and build logs.

Build artifacts and logs (if necessary) can be backed up manually by copying files under .BuildServer/system/artifacts and, prior to TeamCity 9.0, .BuildServer/system/messages. See TeamCity Data Directory#artifacts for details. If logs are selected for backup, TeamCity will search for them in all artifact directories currently specified on the server.

Note that for large production TeamCity installations, exporting and importing of data from/to the database may not be an optimal solution and maintaining database backup via replication might be a better option; e.g. see the corresponding documentation for MySQL database.
