LiteSpeed Engine will work with either a LiteSpeed Engine for SQL Server license or a LiteSpeed for SQL Server Enterprise license. You may view or update licensing information using the Help | License option.
A configuration file contains the file extensions to be monitored, as well as the compression level and encryption level employed by LiteSpeed Engine when creating a backup of the monitored file. By default, LiteSpeed Engine is configured to backup using Compression Level 1 without encryption. You may change these settings at any time. If no custom file extension settings are saved to the configuration file, only native SQL backups will occur.
Configuration settings are saved to the default .ini file (LSBackFilter.ini) and are saved in the Documents and Settings\All Users\Application Data\Quest Software\LiteSpeed\Engine directory. (The default location for the ini file on Windows Vista is: ProgramData\Quest Software\LiteSpeed\Engine.)
The default location is specified by the
HKEY_LOCAL_MACHINE\Software\Quest Software\LiteSpeedEngine\IniPath registry key.
NOTE: The driver currently only updates using the default file name and from the default location.
The configuration file is comprised of two main sections, the GLOBAL section and a sequentially numbered EXTENSION section for each custom file extension. The GLOBAL section contains licensing key information.
The EXTENSION section(s) are sequentially numbered according to the order in which they are entered. Each section contains information on the saved custom file extension settings. These setting may include the following:
NOTE: You need to update driver configuration each time you manually edit the configuration file. For more information, see Manage Configuration Files.
File extensions available for monitoring:
The degree of data compression:
Encryption algorithms used to encrypt data:
1 to 255 characters.
This parameter is only set when data is encrypted.
The user must maintain the password for each encrypted backup file. For appended backup files, the password must be available at the time of each backup, as SQL Server reads previous backup information, and therefore LiteSpeed must be able to decrypt that information when requested.
CAUTION: If the password for a file extension is changed, previous backups cannot be restored until the proper password is re-associated with that file extension. Alternately, the file can be renamed to a new extension which is assigned the previous password.
