2063.0. "Archive Bits" by MTWAIN::MACDONALD (WA1OMM 7.093/145.05/223.58 AX.25) Fri Dec 30 1988 13:45

    Archive Bits
    
    I finally broke down and backed up my swelling 40 Mbyte hard drive
    the other night. 16 floppies and 5 hours using MRBACKUP V2.4. Gotta
    do it though ...
    
    After performing the backup, I assumed that the archive bit would be
    set on all the files. However, when I did a LIST command, quite
    a few of the files listed as ---RWED rather than --ARWED. It appears
    that selecting "Ignore Archive Bit" from the MRBackup menu ignores
    it completely. I have assumed all along that when the A bit is set 
    (--ARWED) that it indicates the file is the currently backed up 
    version. True?
    
    I also assumed that if I were to edit a file that has the archive
    bit set (--ARWED) that the protection would automatically change
    to (---RWED). However, this does not seem to be the case. Edited
    files that had the archive bit set remain with it set even after
    changes have been made. Is this a bug or am I missing something
    somewhere?
    
    To further confuse matters, when I list files with the V1.3 LIST
    command, the results involving archive bits are just the opposite
    of what DiskMaster shows.
    
    DiskMaster will display a file's protection as ---RWED while the
    LIST command displays it as --ARWED. I assume the LIST command is
    accurate.
    
    So, can anyone venture forth and provide some details (missing from
    the Commodore documentation) about the purpose of the Archive bit
    and what good is it?
    
    Thanks.

    I use Quarterback for my hard disk backup.  It moves fairly quickly,
    about a megabyte/minute.  It seems to honor the ARCHIVE bit properly.

    I also use Quarterback.  After doing much the same thing that you did,
    I noticed that all files except DIRECTORIES had their archive bit
    properly set.  By the way, with Quarterback, I take a full backup once
    a month, and set the ARCHIVE bit.  Then once a week for the rest of the
    month, I backup all files that have not had their ARCHIVE bit set. 
    Seems to keep the chore quite managable.

    A megabyte/minute!  Really?  Garsh, I just may have to spend a few
    bucks on it.  I've been chugging away with MRBackup, and get really
    tired of waiting so long for it to finish.

    Just bought it at Mem Loc. Whew! After a 5 hour backup last week
    using MRBackup, Quarterback did it in exactly 30 minutes (19 disks).
    I am impressed. Worth every penney!

    Quarterback Question
    
    Will Quarterback work correctly if "IT" is installed and run from
    the hard disk you're backing up?

    Yes,  that was one of the reasons that I purchased it.  No copy
    protection, no strange loading sequences, etc...  For Workbench folks,
    you just point and shoot.  For CLI/Shell gurus, your just one command
    away.  I am very pleased with the product.  They just came out with a
    new version (2.0) that includes:
    
    	o  Two-drive restore
    	o  User define names and directories for archive/restore reports
    	o  Uses Preferences for report page size
    	o  Backup/Restore names saved in the Quarterback parameter file
    	o  AND (!!) it works with the full size of the Amiga screen,
    		whether it is NTSC, PAL, MOREROWS, etc...  (!!)
    
    I'm going to have to get that disk mailer.  All that I have to do is
    mail the original disk plus $15.00 for the new version.  Not a bad
    upgrade cost -- actually quite impressive !!

Re: .6

Quarterback is a great program:  easy to use, plenty of features, and
fast.

I have the upgrade discussed in .6.  A important new feature not mentioned
in .6 is that the new Quarterback can backup to any AmigaDOS device.   So
if you get a streaming tape drive or 10 or 20 Megabyte floppy, you can
use it to backup your hard disk.

    When Quarterback is backing up to a floppy, can it handle a file
    that is larger than one floppy?  I am using MRbackup because it
    can do this, and I have a file that is 900KB.

    Yep .. it would have a tough time backing it up if it couldn't!
    From the manual, "handles files of unlimited length."

2063.11Quarterback review (positive)SAUTER::SAUTERJohn SauterFri Jan 13 1989 16:1522
    I picked up Quarterback yesterday, and tried it out.  It runs much
    faster than MRbackup.  With MRbackup it takes me all night to back up
    my half-full 40MB disk, whereas with Quarterback it takes only an hour.
    (It could have been faster, but I specified read-after-write.)
    
    After backing everything up I restored it, just to be sure I could.
    It took about an hour to do the restore.
    
    I can see only two disadvantages compared to MRbackup: Quarterback
    doesn't do file compression, and it won't restart partway through a
    save.  Not doing file compressions means it needs 28 floppies instead
    of MRbackup's 23 (approximately).  No restart capability means if I get
    a crash I must restart the backup from the first floppy.  However, with
    the whole process taking only an hour that isn't so bad.
    
    Quarterback really keeps you busy changing disks; fortunately it lets
    you get one ahead of it, so you can leave the room for two minutes
    without it stopping.  Of course, you need two drives to do this.
    
    In conclusion, I recommend Quarterback.  I was in the market for a
    streaming tape for backup; now I'm not sure it is needed.

Re: .11

>No restart capability means if I get a crash I must restart the

Although Quarterback cannot restart after a crash, it can continue after
an output error or read-after-write validation error.  It asks for a new
floppy, and then rewrites all of the information it put on the bad floppy
to the new floppy.

I've had a backup floppy go bad on me, but I've never crashed the machine
during a backup.  I usually do backups while watching TV when I have no
desire to compute.  If I am not watching TV, I usually run the shareware
Missile Command game.  All of that DMA into fast memory by Quarterback
slows the game down to the point I can get some really high scores.

    I'll take the extra floppies over the five extra hours anyday!
