file-rename

I am creating a back up solution. I doubt there is anything new in what I'm trying to achieve.

Before copying the file I want to take a backup of the destination file in case anything becomes corrupt. This means renaming the file.

I have to be careful when renaming in case the file already exists and adding a 01 to the end is not safe.

My question is, based upon not finding the answer else where, would adding a GUID to the file name work. So, if my file was called file01.txt, renaming the file to file01.txtGUID (where GUID is the generated GUID), I could then perform my back up of that file (at this instance having 2 back ups) and then, after ensuring the file has copied (by comparing length of file to the source), delete the file with the GUID in the name.

I know the GUID is not 100% guaranteed to be unique but would this suffice?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More

MS SQL Database with clustered GUID PKs - switch clustered index or switch to sequential (comb) GUID

We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs).
