LiteSpeed for SQL Server 8.5 - Engine Release Notes

Compatibility with LiteSpeed for SQL Server

LiteSpeed Engine for SQL Server is a complementary technology to LiteSpeed for SQL Server (LiteSpeed). By providing LiteSpeed’s compression and encryption functionality in a driver based solution, you can continue using native or third party backup tools, while getting the full advantage and flexibility of LiteSpeed’s time and space saving features.

LiteSpeed for SQL Server is a fast and flexible backup and recovery solution that allows database administrators to easily maintain complete control over the backup and recovery process. LiteSpeed's low-impact, high-performance compression and encryption technology helps reduce storage costs and protect data, while maintaining a high level of recoverability.

A LiteSpeed Engine backup can be restored with either LiteSpeed or LiteSpeed Engine.

The following table compares the different versions of LiteSpeed for SQL Server compatible with LiteSpeed Engine:

Feature LiteSpeed 5.2 LiteSpeed 6.0 LiteSpeed 6.1 and higher
Can restore backups created with LiteSpeed Engine 1.1. Yes Yes Yes
Can restore backups created with LiteSpeed Engine 2.0. No Yes* Yes

Can create backups that are restorable by LiteSpeed Engine 2.0.

(This functionality may be useful for environments, which only have LiteSpeed Engine installed.)

No No

Yes**

 

*—May be not restorable, if encryption options were changed for appended backups.

**—If a backup is created using the new @LSECompatible (xp) and --LSECompatible (command-line) parameters implemented in LiteSpeed. See the LiteSpeed 6.x online help for more information. Also, an appended backup is restorable, but the previous backups become invisible.

NOTE: Forward compatibility is not supported.
