- Difference between BACKMW ver 2.6 and 2.7:
-
- New initial menu selection R = RESTART.
-
- After using the program on a regular basis I found it is easy to
- hit ^C or misalign a disk or somehow abort BACKMW during an
- incremental backup. It is a mess then trying to continue without
- having to backup all that backed-up data again (like, an abort for
- an open drive door after backing up 200 of 300 cylinders...)
-
- The "R" selection in the entry menu can now be used to restart
- the program. THIS WILL ONLY WORK IF ALL CRC DATA IS STILL IN RAM,
- I.E. IMMEDIATELY AFTER AN ERROR OR INADVERTENT ^C ABORT, ENTERING
- WITH THE ZCPR "GO" COMAMND OR VIA A 0K .COM FILE. The R command
- will also work if the program is re-executed via a disk load,
- as long as the CRC map is intact. The CRC map usually starts at 1A00H.
-
- Selecting "R" before "I" and "B" will cause the CRC file loader
- routine to be skipped.

- Difference between BACKMW ver 2.50 and ver 2.60:
-
- 1. SYSLIB3 now used in linkage
-
- 2. When during an incremental backup or recovery a CRC of EAF8 is
- encountered (indicating a cylinder of all E5s -- blank) this
- cylinder is skipped and EAF8 is entered into the CRC file.
- This speeds up operation when copying to/from a disk with large
- blank areas. You might consider running the program called "EFIVEIT"
- before backups, especially if a considerable number of files
- has been deleted.
