[comp.sys.mac] Possible RETROSPECT bug

delaney@xn.ll.mit.edu (John R. Delaney) (07/18/89)

Does anyone have an email address for Dantz, the makers of Retrospect. I
would like to report an apparent bug and prefer to do so in electronic
writing, not by telephone or USnail.

For curious Retrospect users:

The problem seems to be with the Browser command SAVE HILITES. It does
produce the appropriate select when used once. But try using it twice with
the same name for the selector and with the second set of hilited files
being a superset of the first. AS one would hope, you get a dialog that
asks if you REALLY want to overwrite the first selector. But it seems as if
the second selector, not the first is discarded.

For very curious Retrospect users:

I was trying to set up a simple custom selector to use for regular backups
of modified files. But to keep the amount of media I was using down, I
decided I would exclude those files I already have well backed-up
otherwise (e.g., the Word application and its associated dictionaries,
standard system folder files, et cetera). And I thought I might want to
increase these exclusions over time. So I created a selector (which I made
standard by adding the appropriate prefix) called "recoverable files" using
a new Browser in which I hilited all the files I did not want backed-up and
applied SAVE HILITES. Then I created another selector (which I also made
standard) called "full backup" which was simply a NOR of "recoverable
files". It worked fine when I then made my backup archive with "full
backup" as the sole selector. But I noticed I had missed a few files I had
not really wanted backed-up. So I made another new Browser, applied
"recoverable files" to get the same files hilited as before, hilited the
ones I had missed, again did SAVE HILITES, and again supplied the name
"recoverable files" (with the appropriate prefix). A dialog popped up
asking me if I was sure I wanted to do that; I did it. Then I tried a
second backup using "full backup" as the sole selector; it backed-up the
files I had tried to exclude. Further experimentation with new Browsers
seemed to prove my change to the "recoverable files" selector was not
taking.

John,

Dantz is here, under the name "dantz" . I just saw 
your message this morning, and have checked out the problem. 
You did find a small bug in Retrospect in the Save Highlights 
area as follows: 

If you try to replace a save highlights selector that is in use 
by creating a new one with the same name, the first selector 
is not replaced and no warning is given. 

The intended behavior is to not allow you to replace a selector 
that is in use. This will be fixed in the next version. This 
would be consistent with the existing selector architecture which 
does not allow you to delete a selector that is in use. What 
is really happening when you save a new selector with the same 
name as an existing one is that the first one is deleted and 
the second one is created. Because of this, in the next version 
of Retrospect, an alert would appearing saying "The selector xxxx 
could not be deleted because it is in use." 


The best way to work around this is to create a new selector 
when you want to change what gets excluded from the backup, put 
it into your "Full Backup" selector, and then remove and clear 
the old selector. 

Thanks for taking the time to put up such a detailed description 
of how to reproduce it. I was able to figure out the problem
very quickly. Let me know if you have any other problems or 
questions. And, as I said, we will definitely fix this in the 
next version.

Hi "Dantz"...  

Has Dantz considered a promo offer for your new backup software such as that
offered by Fifth Generation for FastBack II?  Now that is a great promo!

Just wondering...

Ray

Ray,

No, we are not currently planning to offer a comparable promo
with Retrospect. 

Thanks for asking...
