Acronis Question

[Guest]

I've using Acronis and an external hard drive to do full image backups.
Every couple of weeks I just do another full image - I don't "add" to it and
do incremental backups... I have Norton 360 and Windows backup my files.
What is werid is when I delete my Norton 360 or Windows backed up files it's
takes quite some time to delete them (about 5GB's of stuff) but when I delete
my Acronis full image (about 17GB's of stuff) it takes only seconds. It
says, "Do you want to move this to the recycling bin" I say "yes" and then
"poof" it's gone. No processing time, etc. How is that possible??? How can
it delete a full image backup at 17GB faster than it deletes my files at
5GB??? I'm wondering if I'm doing something wrong and it's not really
deleting it ya know... anybody have an answer as to why this is...

Thanks,
Sandy

When you "delete" the Acronis file, the file's 17GB content is not deleted.
Only its entry in the directory structure is modified to indicate that
file's space is now available. Are your Norton 360 and Windows backup files
'single files' or a bunch of little files, each of whose directory entries
have to be modified? Or perhaps they are incremental backups which has to
be rearranged to get rid of the deleted parts?

Hi Paul, Thanks for responding! I took this question over to the
Acronis forum and someone suggested the same... that my Norton and
Windows backup files are "single" files so it takes longer than one big
file (like my Acronis image) to go to the recycling bin. I don't do ANY
incremental back ups for any program. I always start over and do entire
"new" ones (why... I don't know... that's just how I roll.)

You said, "When you "delete" the Acronis file, the file's 17GB content
is not deleted. Only its entry in the directory structure is modified
to indicate that file's space is now available." I'm not sure I
understand... in the end I want to make sure that every time I do a
"new" full image from Acronis the "old" one that I deleted is indeed
"gone." I don't want "data" hanging around somewhere I don't know
about. Do I need to do some kind of "clean" after I delete something
that large??? I have CCleaner and Norton 360. I just don't want to
miss something... keep deleting large amounts of stuff and get a future
problem some time down the line...

Any feedback would be appreciated...

Long ago and far away, there was a program called Disk Wipe. I believe
it was made by Norton. It would overwrite the "deleted" space with all
zeros, then with ones or some other character. There was a so-called
government wipe which repeated this sequence seven times. That sounds
a little paranoid, doesn't it?

And now you can get a prog called Eraser for free that will wipe individual
files, all selected files, and free space if you choose. Anyway, you have
now confused him with your explanation of what the delete button actually
does. As far as windows is concerned and for his purpose the file is gone
and can only be retrieved with an undelete utility, and probably not even
with that if it has been overwritten by another file that wrote to the same
sector. Acronis won't see the deleted file so don't worry about wiping it.
Wiping is good though if you have some sensitive data in the image file that
you don't want anyone to be able to ever retrieve. Wiping is good too if you
suspect a file of containing a virus.

 

[Paul Randall]

If you don't want data hanging around, then you need to run a file "wiping"
program on the file before you delete it. Someone else suggested eraser,
which may work just fine. I don't feel I need to use such a program, but
your data may be more sensitive than mine. It is not likely that your data
would come back to haunt you unless someone steals your hard drive or
someone runs an undelete program.

As I understand it, when you delete a file, any file, in Windows the file is
not actually erased from your hard drive. Instead the entry for the space
that file occupies is marked as unoccupied in the file table. In my
experience, this does not create any "performance Problem."

Human beings, who are almost unique in having the ability
to learn from the experience of others, are also remarkable
for their apparent disinclination to do so.

Correct on both counts.
