[comp.sys.apple] Hard disk backup problems

hartkopf@tramp.Colorado.EDU (HARTKOPF JEFFREY M) (07/12/89)

Recently I posted to the net how I was having problems restoring a hard
disk backup I made with Backup II.  No one responded, so I thought I had
better repost and clarify myself, because I *REALLY* need an answer.  I
probably wasn't very clear that day since I was rather shaken up.

The problem is this:  My hard drive is partitioned into a 32MB and 8MB drive.
I had some problems, so I reformatted both with the same partitioning.  Then
I wanted to recover everything which I had on backups made previously with
Backup II from Apple.  Backup II wouldn't restore *either* drive, but
I kept just my software on the first drive so I was able to fix that one
by just reinstalling all my software.  HOWEVER, the second drive had all of
my data (word processing, data bases, *my programming*, etc.).  The backup for
this drive is on 3 3.5" disks and is current, since I have backed it up fairly
often and as far as I know Backup II backed it up correctly (although they
were incremental backups, I only did one full backup when I first got my
hard disk about 3 months ago).  When I tried to restore the disk using
Backup II, it restored the entire first disk of the 3, but then stopped
with the message "Operation complete", which it certainly wasn't!  It still
had 2 disks to go!

So, any suggestions or solutions this time?  Anyone who's familiar with
Backup II?  If nothing else, at least is there a way to restore the files
manually?  Thanks *very* much for any answers.

As I recall (from a similar experience several years ago, where I ended up
restoring some files manually), Backup II stores each file in a sequential
clump of blocks, so you can read the blocks into memory manually and BSAVE
the files manually (and fix up their filetypes/auxtypes).  I don't remember
whether the clumps were *really* sequential, or whether it just happened that
way because nonfragmented ProDOS files are already that way.
