N LOGGING-VD, Storage_Management, Virtual disk that logs all writes to a logfile  C This area contains my VAX driver (not touched for a few years) that B can (using logdata.ftn) log writes to the device to a logfile. TheB idea was to give continuous backup. The logfile contains LBN, timeD (to 64 bits), and PID of the writer, and the data written so that itC can be re-recorded to play forward from a physical backup up to any C time. The logger currently writes a block's worth at a time, though A that can easily be altered. FVdriver, LOGdata.ftn, and FVHST* are  the relevant routines.  F Also an older version of my back/phys tape as disk utility sources are present here in zoo files.  D Creation dates are not all exact; these have been copied and renamedC a number of times. The files data from generally late 1991 to early  1992.    Glenn Everhart      G (ps - check out Safetyspd.txt here...some useful things are described.) 
