I'm looking for a HD backup/restore program that can correctly restore incrementally saved
read-only files. That is, if one does:
echo >A.File "First line"
protect A.File -wd
(backup A.File - call this one BACKUP 1)
protect A.File +wd
echo >>A.File "Second line"
protect A.File -wd
(backup A.File - call this one BACKUP 2)
protect A.File +wd
delete A.File
(restore BACKUP 1, A.File should be protected -wd)
(restore BACKUP 2)
The second restore should silently overwrite the A.File restored from BACKUP 1,
and leave it protected -wd.
So far, I know that Matt Dillon's backup/restore doesn't handle this case, and
neither does QuarterBack (from a friend's test).
Please either post replies, or send them to the addresses in my .signature - the address
in the From: line has been made logically equivalent to /dev/null :-(
