When you do incremental backups, what happens when you delete a file because you don't want it on your machine and then you do a back up. I assume that file is still within the backupfile and will be reinstalled when and if you do a restore.

Is there a simple way of removing files from your backup data so they will not restore.
I am particularily thinking of a lot of shareware, 30 trial stuff that I would want reinstalled.

Thanks.

Never assume. If you use that backup to restore, the file will not be
reinstalled.
 
Thanks for the info, but just to make sure I understand, If a file is saved
during a backup and then later taken off the computer and then an "update"
of the back up is made, the system will go into that data base and delete
any files that have been deleted since the last backup.

Just understand that your deleted file will not be reinstalled.
Period.

No. Think of it this way: a collection of bottles on your mantle represents
your files on your computer. You take a picture of them. That picture is
your backup file. Then you decide to throw away a few bottles from the
mantle. If you could "restore" the bottles on the mantle with the backup
picture then all the original bottles would be back.
The backup utilities will not delete files from the backup file archive that
have been deleted from your computer - that would defeat the purpose of
backup software.
But the better applications will allow you to selectively restore individual
files rather than the entire "photograph" - if that helps.

Except that if an incremental backup (another picture taken after the
bottles were thrown away) was made after the file(s) were deleted, then one
would expect that those files would not be restored.

Cute, but it doesn't fully handle the question of making a complete
restore from a backup that has had several incremental backups made
after the original was made.

If one makes a complete restore of the entire package, no files that
were deleted between the making of the original backup and the making
of the most recent incremental will be restored.

That's just the way it is. I couldn't care less how it's done, just
that it works.

They won't restore by doing a complete restore, but if you are uneasy
about it just delete the backup set and make a new one.

In reality, I'd do the opposite: Make a new backup and THEN delete the
old one. I'm sure that's what you meant. ;)

Yes, of course. My bad.
