PDQ Deploy stores all of its data—schedules, package configurations, target lists, preference settings, credentials, deployment history, etc.—in the PDQ Deploy database. This SQLitedatabase is critical to program function.
The database file, database.db, is stored in folder, %ProgramData%\Admin Arsenal\PDQ Deploy.
NOTE: %ProgramData%, which was introduced in Windows Vista and used in subsequent Operating Systems (Windows 7, 8.x, 10, etc), is a special Windows folder designed to hold application-wide (that is, not user-specific) data. By default, Windows marks this folder as hidden so you won't see it when using Windows Explorer. Its default location is %SYSTEMDRIVE%\ProgramData. If you are running PDQ Deploy on Windows XP or 2003 (no longer supported), the default location is %SYSTEMDRIVE%\Documents and Settings\All Users\Application Data.
The PDQ Deploy database is made up of the following files:
File |
Description |
Database.db |
This is the main SQLite database file that holds all of the computers, inventory, collections, reports, etc. |
Database.db-shm Database.db-wal |
These files are used by SQLite while accessing the database. They can be deleted without affecting the system as long as no applications or services are accessing the database. If you move PDQ Deploy to another computer, they don't need to be copied to the new computer with the database file, but it won't hurt if they are. However, if you restore a database backup file, you must delete these files. Otherwise, PDQ Deploy will think the restored database file is corrupted. |
The database file, database.db, is not removed on uninstall in case the software is reinstalled. If you move PDQ Deploy to another computer, the PDQ Deploy database must be duplicated on the new computer in order to maintain your PDQ Deploy settings and system data. For detailed information on this procedure, see Moving PDQ Deploy to a New Computer.

Database Security
Your security is very important to PDQ. To that end, we encrypt sensitive information (passwords) when they are stored in the PDQ Deploy database. We use industry standard AES encryption with three separate keys to keep your data safe. One key is built into the application; one key is stored in the database; and the third is stored in the registry. These last two keys are generated when the application is installed and are unique to your system.
Our support staff may ask you to send your database to us in order to troubleshoot a problem. We will never ask you to send us the encryption key stored in the registry, so you can be sure that your passwords are kept secure.
If you need to move your database from one computer to another you should include the encryption key in the registry. (For detailed information on this procedure, see Moving PDQ Deploy to a New Computer.) If the key is lost, then all passwords stored in the database will need to be re-entered. No other data is lost.
Database Backup Files
Each time you install a new version of the PDQ Deploy software, a database backup file is created in the %ProgramData%\Admin Arsenal\PDQ Deploy\Backups folder. The backup file is compressed and is named after the version of the database. For example, Database.6.2.0.0.db.gz.
NOTE: The database version numbers represent the exact version of PDQ Deploy at the time of backup. For example, when upgrading Deploy 6.2.0.0 to 7.1, the existing database is copied to a file called Database.6.2.0.0.db and then, after a small interval, it is archived in the .gz format.
Older backup files can be safely deleted, but you may want to keep the most recent backups in case you need to restore the database.
Restoring Database Backup Files
In the event that your database is deleted or corrupted, you can restore a database backup file.
Locate the backup database file you wish to restore:
1.Click Options > Preferences (or press Ctrl+Comma), then select Database.
2.The backup location of the database is specified in Backup Location. By default, the backup database files are located in %PROGRAMDATA%\Admin Arsenal\PDQ Deploy\Backups.
3.Navigate to the directory indicated in Backup Location or click the Open Folder Location 
button.
4.Locate the backup file from which you wish to restore. The backup file is named after the version of the database with the date and time the backup was performed. For example a backup of version 9 performed on March 23, 2016 at 2:32 PM will be titled PDQDeploy- 9.1.0.0-16-03-23 1432.db.cab.
Restore the database from the backup:
1.Decompress the database backup file.
Most compression utilities, such as WinZip and 7-Zip, can decompress cabinet files.
2.Rename the file to Database.db or create a copy of the original file and rename it to Database.db.
3.Stop the PDQ Deploy Service.
This is done in Options > Preferences > Background Services, or press Ctrl+Comma then select Background Service. Alternately, you can access services through the Windows Start Menu > services.msc.
4.Overwrite the existing database file in folder %ProgramData%\Admin Arsenal\PDQ Deploy.
5.Delete the Database.db-shm and Database.db-wal temporary files.
WARNING: If you do not delete these files, PDQ Deploy will think the restored Database.db file is corrupt.
6.Start the PDQ Deploy Service.
This is done in Options > Preferences > Background Services, or press Ctrl+Comma then select Background Service. Alternately, you can access services through the Windows Start Menu > services.msc.
Restoring A Database Using a Command Prompt
To restore the PDQ Deploy database using a Command Prompt:
1.Run cmd.exe as Administrator.
2.To view the options available when restoring the database, use the following command: PDQDeploy RestoreDatabase.
| This will display all the available databases you wish to restore. |
 |
3.Enter the number of the database you wish to restore.
4.(Optional) To automatically restore the most recent database, use the following command instead: PDQDeploy RestoreDatabase -RestoreMostRecent. The database being overwritten will be renamed and left in the same folder.
Maintaining the PDQ Deploy Database
The PDQ Deploy database is essential to the program function; therefore, it is recommended that you perform the following regular maintenance procedures to ensure optimal database performance:
•Location of the PDQ Deploy Database
•Backing Up the PDQ Deploy Database
•Cleaning Up Deployment History
Location of the PDQ Deploy Database
PDQ Deploy stores its database locally (on the PDQ Deploy console computer) in %ProgramData%\Admin Arsenal\PDQ Deploy.
NOTE: %ProgramData%, which was introduced in Windows Vista and used in subsequent Operating Systems (Windows 7, 8.x, 10, etc), is a special Windows folder designed to hold application-wide (that is, not user-specific) data. By default, Windows marks this folder as hidden so you won't see it when using Windows Explorer. Its default location is %SYSTEMDRIVE%\ProgramData. If you are running PDQ Deploy on Windows XP or 2003 (no longer supported), the default location is %SYSTEMDRIVE%\Documents and Settings\All Users\Application Data.
If your console performance is lagging during large deployments, you may consider moving the PDQ Deploy database to a faster disk. For information on this procedure, visit the PDQ Support page at https://support.pdq.com/home and click Submit a Request or email your request directly to support@pdq.com, or click Help > Support > Feedback & Support. You can also browse the PDQ forums for FAQs.
Backing Up the PDQ Deploy Database
Because the PDQ Deploy database stores all package, schedule, and deployment information, it is highly recommended that you regularly backup the PDQ Deploy database. You can setup an Automatic Backup Schedule in the Database page of Preferences. The default backup schedule is weekly on Saturdays at 10:00 PM. The default will also retain 10 compressed backups. (Enterprise mode required)
By default, the PDQ Deploy database is located at %ProgramData%\Admin Arsenal\PDQ Deploy\Database.db. To protect your system data, configure your backup software to regularly back up this file.
NOTE: To determine the location of the PDQ Deploy database, click Options > Preferences or press Ctrl+Comma, then select Database. The Database field displays the path and filename for the PDQ Deploy database. The Backup location displays the path and filename for the backup database files.
To change the PDQ Deploy database backup defaults, perform the following:
1.Click Options > Preferences or press Ctrl+Comma, then select Database.
2.Make the appropriate changes in the Database Preferences window:

Cleaning Up Deployment History
Every time PDQ Deploy runs a deployment, it records the results in the PDQ Deploy database. Each deployment record takes ~5KB of memory. While individually this is a negligible amount, given time and thousands of deployment records, the deployment history can consume significant disk space. For example, in our labs, the deployment history for 6,200 deployments required 32 MB of disk space. The more data in the database, the slower the database will become.
To help you manage the disk space consumed by the PDQ Deploy database, you can configure PDQ Deploy to automatically purge deployment history records after a specified number of days. You can customize this value based on the number of deployments you run and how long you wish to see the results of finished deployments. The default age is 30 days, i.e. one month after the deployment finishes.
Setting the cleanup to 0 days disables automatic cleanup; PDQ Deploy never deletes the deployment results.
WARNING: Keeping this value high or setting the value to 0 may cause the PDQ Deploy database to get very large which could slow PDQ Deploy performance.
To specify how many days you want to archive deployment histories in the PDQ Deploy database before they are deleted:
1.Click Options > Preferences or press Ctrl+Comma.
2.In the Preferences window, click Deployments.
3.Set the Cleanup field to the number of days you want to maintain the deployment history before they are deleted.
4.Click Close.
Optimizing the Database
When PDQ Deploy deletes information from the PDQ Deploy database, it leaves empty space in the database file which takes up a few bytes. Over time, this space adds up and may impact database performance. Therefore, it is recommended that, on average, you optimize the PDQ Deploy database once a month. Optimizing the database frees up the empty space and gets rid of fragmentation.
NOTE: If you are running a high volume of deployments and you have configured PDQ Deploy to clean up the deployment history <30 days, you may want to optimize the PDQ Deploy database more frequently.
NOTE: PDQ Deploy automatically optimizes the database when the application is upgraded.
To optimize the PDQ Deploy database:
1.Click Options > Preferences or press Ctrl+Comma.
2.In the Preferences window, click Database.
3.Click Optimize Database.
NOTE: PDQ Deploy warns that the console and background service will be stopped, which will abort any running deployments.
4.Click OK to continue.
PDQ Deploy opens a command line window to run the optimization command.
5.When the optimization completes, press Enter to close the command line window.
PDQ Deploy automatically restarts and opens the Preferences window.
6.Click Close.
