Hello,
Espionage is using sparse bundle disk images to store protected files. Sparse bundle disk image is not one file, it is a collection of small files called stripes or bands packed in one OS X package. When changes to data in disk image happens (when you unlock the folder the disk image mounts and by adding/updating the files, you are updating the bands of disk image).
When the folder is locked, the disk image is unmounted and closed, sitting on your file system.
So I would say that you can safely run defragmentation of these files but to prevent Espionage kicking in, first lock all the folders and disable them in Espionage. Then run the defragmentation process. Once done, just enable the folders in Espionage and you are done.
If the backup is not set up in Espionage, and you have sufficient space on your disk to have all your protected folders copied, then I would advise you to set it up, you never know what can go wrong. Note that the backup will run the first time you unlock and then lock the protected folder. On the first run it will make a full copy of the data, so it might take some time, on subsequent runs it will copy only the differences, so it goes fast.
Let me know if you have further questions.
