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