Restoring TeamCity Data from Backup
TeamCity administrators are able to restore backed up data via the TeamCity UI or by manually using the
maintainDB command-line utility.
You can restore backed up data into the same or a different database; from/to any of the supported databases (for example, you can restore data from a HSQL database to a PostgreSQL database, as well as restore a backup of a PostgreSQL database to a new PostgreSQL database).
A newer version of TeamCity can be used to restore the backup created with any previous TeamCity version (provided that the TeamCity version is later than 6.0).
During restoration of a large database you might want to configure database-specific settings to make the bulk data changes faster (like setting SQL Server "Recovery Model" to "Simple"). Consult your DBA for more details.
A TeamCity backup file does not contain build artifacts, so to get the server with all the same important data you need to restore from a backup file (at least settings and database) and copy the build logs and artifacts (located in
TeamCity Data Directory
>/system/artifacts by default) from an old to the new Data Directory manually. The general compatibility rule of the data under
system/artifacts is that files created by older TeamCity versions can be read by newer versions, but not necessarily vice versa.
See also details on the directories in the TeamCity Data Directory description.
Since version 2019.2, TeamCity can automatically restore the backed up data. The automatic restoration process also relies on the maintainDB utility, but performs all the necessary operations under the hood. To restore the backed up files on the first start of the TeamCity server:
On the TeamCity First Start step of the browser dialog, enter the path to the Data Directory and click Restore from backup.
Enter an absolute path to the backup directory on the TeamCity server or upload a ZIP archive with the backed up data.
Choose the target database. If you use an external database, configure its address and credentials.
Proceed with the restoration.
TeamCity will restore the data and display the maintainDB utility log. If the version of the backed up data format is earlier than the current one, TeamCity will propose to upgrade it.
Alternatively, you can use the maintainDB utility manually. This section describes only some of the
maintainDB options. For the complete list of all available options, run
maintainDB from the command line with no parameters. See also maintainDB startup options.
To perform restore from a backup file via maintainDB:
Install the TeamCity server from a
.exeinstallation package. Do not start the TeamCity server.
Create a new empty TeamCity Data Directory.
Choose one of the options:
To restore the backup into a new external database, create and configure an empty database, configure a
database.propertiesfile with the database settings to be passed to the
restorecommand later on and either place it into the
/configsubdirectory of the newly created TeamCity Data Directory or anywhere on your file system outside the TeamCity Data Directory.
To restore the data into the same database the backup was created from, proceed to the next step.

c. To restore the backup into the internal database:maintainDB.[cmd|sh] restore -A <absolute path to the newly created TeamCity Data Directory> -I -F <path to the TeamCity backup file>
If the process completes successfully, to complete the restoration you need to copy over <TeamCity Data Directory>/system/artifacts from the old directory. The directory stores build artifacts and those are not included into the backup file.
Notes on the
restore command options:
-Aargument can be omitted if you have the
TEAMCITY_DATA_PATHenvironment variable set.
-Fargument can be an absolute path or a path relative to the <TeamCity Data Directory>/backup directory.
-Targument must point to the
database.propertiesfile created in step 3.
-Targument is not specified and the
database.propertiesfile is present in the newly created
<TeamCity Data Directory>/configand the backup file, the database is restored using the properties file in
<TeamCity Data Directory>/config.
By default, if no other option except
-Fis specified, all of the backed up scopes will be restored from the backup file. To restore only specific scopes from the backup file, use the corresponding options of the
Restoring database only
When restoring the database but preserving the more recent TeamCity Data Directory, it is important to make sure the data is consistent:
<TeamCity Data Directory>/system/pluginData (supplementary data) should be restored as well to be consistent with the data stored in the database
<TeamCity Data Directory>/system/caches should be cleared before the server start
Before restoring a TeamCity database to an existing server, make sure the TeamCity server is not running.
To restore a TeamCity database only from a backup file to an existing server:
Create and configure the database, placing the
database.propertiesfile into the
configsubdirectory of the
TeamCity Data Directory.
Ensure that the required database drivers are present in the
maintainDButility located in the <TeamCity Home>/bin directory (only available in TeamCity
If the supplementary data is present in the backup, delete the content of the <TeamCity Data Directory>/system/pluginData directory (consider backing it up in another location first).

database.propertiesfile manually if requested.
Delete the contents of the <TeamCity Data Directory>/system/caches directory.
Resuming restore after interruption
The restore may be interrupted due to the following reasons:
Lack of space on the file system or in the database
Insufficient permissions to the file system or the database
The interruption occurs when one of tables or indexes failed to be restored, which is indicated in the
maintainDB utility console output.
Before resuming the restore, manually delete the incorrectly restored object from the database.
To resume the backup restore after an interruption:
