Pstdelta 060315

Pstdelta project has been created in order to vastly reduce the size of differential backups of .pst files.
Administrators of Windows networks running Outlook will often find their networks clogged with Outlook pst files. These files are often around 1GB in size.
Since these files change every day the nightly backup will have to save them every day. This means that space has to be made for 1GB per user per day.
Pstdelta can be used to store the differences between an old and new version of a pst file. It can then generate the new file using just the old file and the output generated by pstdelta.
NOTE: this program has been stable for me for a while. However, running verify after making a delta file is probably a good idea.
Enhancements:
- This release fixes a bug that caused verification failure in specific situations.
- It adds a nightly script to help facilitate the use of pstdelta in differential backups.
