Export and Backup of Database Contents

There are different mechanisms for backing up and restoring data maintained by a PMOD database. This functionality is only visible on the Selected for backup or replication tab. The options can be found on the configuration button in the lower left bottom.

DB Backup Operations

Replicate to

Copy data from one database to another online database.

Move to

Copy data to another online database and delete the original information.

Export DICOM

Copy data to a directory.

Export Database
(Selected)

Export the selected data together with the describing database attributes into a composite backup file (.bkp).

Export Database (Whole)

Export all data of the database into a composite backup file (.bkp).

Import Database

Restore data from a composite backup into an arbitrary database.

C-Store

Sends all selected images to a DICOM server.

Export DICOM

To export images from a database using Export DICOM option, the following steps must be performed:

  1. Select the source database from which data should be exported. The Components Administration tab must be selected for switching databases.
  2. Activate Selected for: replication/.. tab.
  3. "elect the patient(s) to be backed up, then activate the Set as "Selected for Loading" button. To incrementally add more data, select patients/series and then activate the Add or Add all buttons. Note that image and component data are backed up with this procedure.
  4. Configure the operation selection to Export DICOM. A dialog windows appears listing the series selected for export. A DICOMDIR can optionally be created which lists all image data, and the whole information can be packed into a zip archive.

    EXPORT DICOM

  5. Finally activate the Export to File system button. The selected components are exported to the selected output directory and organized in a hierarchical structure, so that all data belonging to a study end up in a common directory tree.

DB Export Data Result

Export/Import with DB Information

The purpose of this approach is to export data so that they can be re-imported to any other database, which need not be connected. The procedure is similar as described above. However, the result of Export Database (Selected) and Export Database (Whole) is a single file (.bkp) which contains both the data and the database information.

The information in the .bkp file is only accessible through Import Database. When a .bkp file is opened with Import Database, data can selectively be imported to any PMOD database.

CAUTION: The .bkp export is limited to a total size of 2GB due to system limitations and thus not intended as a backup facility. It can be used to exchange data within a Pmod version, while compatibility across different versions is limited.
