Alvin,

DTS Packages are stored in the msdb database. Backing this up regulary provides the most protection.

Alternate way: DTS Packages are stored in sysDTSPacages table, this data can be copied to another table with the same structure on another server (or bulk copied out). Also sysDTSPackages is how I migrate/move dts packages from one server to another. Remember sysDTSPackages is undocumented...
