Software Update Good Practice


Software Update Good Practice:


Here are some simple rules to guide you along a much more secure, safer and more successful software update, with better results than before:


    1. Do not attempt to update a file that can change or has been changed already, on user's machine, before you apply the SecurePATCH file. See here.


    1. Always try to add versioning to your files. It will give you a much better control over what version is already located on the Remote PCs. See here.


    1. Always pay attention to already compressed files. The reason is that a small change in an uncompressed file could lead to major changes in the compressed form. Thus, creating a binary diff file from already compressed files should be avoided and it is not recommended.


    1. The same relates to encrypted files or encrypted data files. Try to avoid performing binary differencing on encrypted data. SecureDELTA already offers a method to securely encrypt the binary diff data it creates.
