Always back up your packages every day or night using package replication and publishing. Because locking information does not travel with packages (or partial packages) when they are replicated, it is recommended that you apply a version to each package according to date. Do not replace or overwrite packages; delete the old package entirely and then install the new package.

When you replicate and publish a package, the locking information is not preserved. This is expected behavior and is part of the feature's design. You can, however, preserve system locks (read-only file attributes).

Before you publish a package, keep in mind that user locks are not preserved.

When you salvage a deleted package, lock information is not preserved. Before you salvage or delete a package, make sure that all locks are removed from the destination package.
