I'm using IomegaBackup98 v.3.2.pro.
Backuptypes are: full----full copy----differential----and incremental.
Backuptypes are: full----full copy----differential----and incremental.
I have 2 questions about these types.
1) What's the difference between FULL - Backup and FULL COPY-Backup??
2) I made a task "full-backup" and therefore i marked all the files on
disk which were
shown in the tree. I used this task for two weeks and now i have
seen some files
(normal txt.files i've made some days ago) are not backupped. So it
seems a full
backup is'nt really FULL??
Anybody knows?? Thanks in advance.

You'll probably get a dozen answers but here's mine:
FULL BACKUP = The backup program makes one file of
your entire disk--you can't read it unless you put the
backup program in the "RESTORE" mode and then you can
restore all or any number of files in the backup. You
can check the files that were backed up from the
"RESTORE" mode and designate files you want to restore
or you can just 'take a look' and then cancel the
operation.
FULLCOPY BACKUP = The backup program will copy all the
files that are on your harddisk and you can read a disk
that contains such files. If you're using a tape
drive, however, it will take a long time to read unless
it also puts a catalog of the files on your harddisk.
I have never used Fullcopy Backup, so I will presume
that it does the same sorts of things as a regular
backup, which is that it does (or can) keep a copy of
the backup filelist catalog on the harddisk as well as
on the tape.
INCREMENTAL BACKUP = all files that have changed since
the last incremental backup. The first one, of course,
will contain all the files that have changed since the
last full backup.
DIFFERENTIAL BACKUP = all files that have changed
since the last full backup (I use full backup for the
first backup on a tape and then do Differentials for
each succeeding backup until the tape is full on the
theory that if I ever do have to do a full restore I
will only have to restore the Full Backup and the last
Differential backup to get back to where I was before
the failure.)

If I haven't explained something, please don't hesitate
to inquire again.
