No problem Dave. I guess I should explain my reasoning. AP/D3 incremental saves only save items that have changed in files since the last full-save. Most people think of "save tapes" as a series of data that just needs to be extracted from the media and written to disk. An incremental save is a stream of instructions along with data. Operations that must be supported include: - Changes to existing items - Deletion of existing items - Creation of new files - Deletion of existing files - Clear-file (doesn't log as a delete of every item) - File-renaming - Changes to existing file sizes All of the above update types must be applied immediately after an account or system restore. To further complicate the matter, indices, object code, and other binary data will require special handling. And it's even worse if the system includes what are called "QS pointers" which save OS data compared to hashed files. It's not a simple task to reverse engineer such a complex process, even with a roadmap of the required functionality. Anyone who doesn't understand the functionality behind those operation types is going to have a particularly hard time. So I come back to my recommendatation that it's better to just pay $500 for a D3 developer license to do this, or to pay someone else to restore an account followed by the incremental data. Oh, and to find someone who still has a floppy drive connected to their PC. ;) HTH T -- Please read the posting guidelines at: http://groups.google.com/group/jBASE/web/Posting%20Guidelines IMPORTANT: Type T24: at the start of the subject line for questions specific to Globus/T24 To post, send email to [email protected] To unsubscribe, send email to [email protected] For more options, visit this group at http://groups.google.com/group/jBASE?hl=en
