SilhouetteConnect File Storage and Backup

The data storage location on the file system depends on the operation mode (Synchronized or Standalone) of SilhouetteConnect.

Standalone Mode Storage and Backup

SilhouetteConnect, in Standalone mode, creates and uses the following files or directories:

%programdata%\ARANZ Medical Limited\SilhouetteConnect\Settings\ - Directory that contains settings files controlling the operation of SilhouetteConnect. Typically the settings that need to be set in these files are configured by options in the install process, in the setup screens or from within the Silhouette application.

There are some settings that can be changed in the MachineSettings.xml file within this directory to control the behavior of SilhouetteConnect. Before changing this file it is best to check with ARANZ Medical support.
- MaximumAgeOfExportedDataInDays - Controls how long export data is stored within the application data directories. The default is 3 days and the valid range is 1 to 7 days.
- MaximumAgeOfOldInstanceDataInDays - Controls how long old instance data archives are kept. The default is 31 days and the valid range is 0 to 365 days.
- Other settings are available to control the database connection and the instance of the ARANZ Medical licensing server used for licensing.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\SilhouetteConnect.lic - The license file for SilhouetteConnect allows it to run on the PC for the appropriate license period.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\Logs\ - Directory that contains application log files for SilhouetteConnect. ARANZ Support Limited may ask you to provide these log files if you are having problems with the application.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\CabInstalls\ - Directory that contains the SilhouetteStar 2 software patch files that are compatible with the running version of SilhouetteConnect.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\Data\ - Directory that contains the clinical data stored on the system. This is kept in a PC wide area (available to all PC users) of the file system to allow multiple Windows users to share data on the same Standalone installation. The data directory contains the physical database files for the MS SQL Express database instance and sub-directories for the captured images and periodic database backups.
- The database for Standalone SilhouetteConnect is stored in a named MS SQL Express instance (typically named SILHOUETTE).
- Periodic backups (weekly and daily) are taken of the database and kept in the Backup sub-directory.
- If you wish to backup data from the PC to a remote file system, backup the Backup and Sdr sub-directories.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\Data_<n>\ - If the SilhouetteConnect installation has been re-initialized at any point in time, any previous data is archived by appending a sequential number to the end of the data folder, before initializing a new data folder.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\CefCache\ - The CefCache folder holds some of the per-device remembered preferences for SilhouetteConnect operation (like tracing stylus use).

A manual backup of the SQL Express database can be taken by running the following command on the command line:

sqlcmd -S .\SILHOUETTE -Q "backup database [Silhouette] to disk='%programdata%\ARANZ Medical Limited\SilhouetteConnect\Data\Backup\Silhouette.bak'"

Contact ARANZ Medical Support for details on how to restore from backups if necessary.

Always take a backup of the database to move or re-locate the Silhouette database, rather than moving the raw ldf and mdf data files.

Sync Mode Storage and Backup

SilhouetteConnect in sync mode creates and uses the following files or directories:

%programdata%\ARANZ Medical Limited\SilhouetteConnect\Settings\ - Contains PC wide settings files controlling the operation of SilhouetteConnect. Typically the settings that need to be set in these files are configured by options in the install process, in the setup screens or from within the Silhouette application.

There are some settings that can be changed in the MachineSettings.xml file within this directory to control the behavior of SilhouetteConnect. Before changing this file it is best to check with ARANZ Medical support.
- MaximumAgeOfExportedDataInDays - Controls how long export data is stored within the application data directories. The default is 3 days and the valid range is 1 to 7 days.
- MaximumAgeOfOldInstanceDataInDays - Controls how long old instance data archives are kept. The default is 31 days and the valid range is 0 to 365 days.
- Other settings are available to control the database connection, the database version, and the instance of the ARANZ Medical licensing server used for licensing.
%localappdata%\ARANZ Medical Limited\SilhouetteConnect\Settings\ - Contains user-specific wide settings files controlling the operation of SilhouetteConnect. These settings are updated from SilhouetteCentral when a sync is performed.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\SilhouetteConnect.lic - The license file for SilhouetteConnect allows it to run on the PC for the appropriate license period.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\Logs\ - Contains application log files for SilhouetteConnect. ARANZ Support Limited may ask you to provide these log files if you are having problems with the application.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\CabInstalls\ - Contains the SilhouetteStar 2 software patch files that are compatible with the running version of SilhouetteConnect.
%localappdata%\ARANZ Medical Limited\SilhouetteConnect\Data\ - Contains the clinical data stored on the system. This is kept in a per-user area of the file system. Each Windows user syncs their own data from the SilhouetteCentral instance, however all users sync to the same instance. The data directory contains the physical database files for the MS SQL LocalDb database instance and sub-directories for the captured images and periodic database backups.
- The database for Syncing SilhouetteConnect is stored in a named MS SQL LocalDB instance (typically named SilhouetteConnect).
- Periodic backups (weekly and daily) are taken of the database and kept in the Backup sub-directory.
%programdata%\ARANZ Medical Limited\SilhouetteConnect\Data_<n>\ - If the SilhouetteConnect installation has been re-initialised at any point in time, any previous Standalone mode data is archived by appending a sequential number to the end of the data folder, before initializing a new data folder.
%localappdata%\ARANZ Medical Limited\SilhouetteConnect\CefCache\ - The CefCache folder holds some of the per-device remembered preferences for SilhouetteConnect operation (like tracing stylus use).
%localappdata%\ARANZ Medical Limited\SilhouetteConnect\Data_<n>\ - If the SilhouetteConnect installation has been re-initialized at any point in time, any previous data is archived by appending a sequential number to the end of the data folder, before initializing a new data folder.
- The data for the user performing the re-initialization is archived when they do the re-initialization.
- The data for the other users is only archived when those users login to the PC and start SilhouetteConnect, and only if the sync URL has actually changed since their last use.

When using SilhouetteConnect in Synchronized mode, then backing up the data from the local PC is not necessary as data is backed up in SilhouetteCentral when a sync is performed.

SilhouetteConnect Archive and Backup Data Retention

Each time a user logs in to SilhouetteConnect the age of the SilhouetteConnect data archives, stored in the Data_<n> folders, is checked and they are deleted if they are older than the MachineSetting MaximumAgeOfOldInstanceDataInDays, which is 31 days.

Adding a key MaximumAgeOfOldInstanceDataInDays in the MachineSettings.xml setup file allows you to control how long data is archived in the data archive folders (Data_<n> folders). The default retention for old instance data is 31 days and the valid settings range from 0 to 365 days.

SilhouetteConnect database backups are controlled by Organizational Settings within the admin part of the application. See the Administration User's Guide for more details.
