[comp.sys.apple] Backup II Failure

wen@pro-sat.cts.com (System Administrator) (01/22/89)

My hard disk was backed up with 56 floppies using Apples Backup II program,
v1.1.1.  During restore by pathname the first 28 floppies worked fine, and the
29th one gave an error (very fatal error) that said the DATE AND TIME STAMPS
DON'T MATCH, HIT ESC TO CONTINUE.  This just takes you back to the menu and
does not let you continue.

The backup was made on an APPLE II+ with a 20 megabyte sider formatted in all
PRODOS.  Since there is no clock, the time is set manually when the computer
is turned on.  The backup was made at one setting and there is no cause that I
can see for the error.  When trying to restore any file that is after the 28th
floppy, the same error occurrs.

Somone has also suggested that Backup II fails when a backup is made across
midnight and the date changes.  It is possible that this occurred if it was
made on the IIe instead of the II+ and I am really not sure which was used.

I have found a matching code on Track 00 Sector 13 starting at byte 20 that is
15 bytes long and seems to match on all disks.  Track 00 Sector 11 seems to
have the backup.volume number.  But have been unable to find out what the
program actually finds that doesn't match.

The data is quite valuable to me, and I can see from a track and sector scan,
that it is there intact, but I would sincerely appreciate any assistance in
patching the program to ignore errors so I can restore the data or what to
patch on the disks to eliminate the error.  I also have a IIe, but the same
problem occurrs on restore.

I guess another approach would be to locate a program that can restore the
BACKUP II format, if that is possible.
