Twayne.......does that mean I can take it to my parents house and do
a back up of their computer with it?
Yes. If your backup utiity has compression, almost certainly. It's
possible but pretty unlikely that you would not have enough room unless
you run a LOT Of programs and have a LOT of data files or huge images.
e.g. this particular machine I'm on at the moment has a total of 2
drives and 5 drive letters, each drive letter at least 50% used and a
total of 440 Gig. I'm using compression for backup, and my 500 Gig is
holding 4 full backups and about 30 incremental backups per full backup,
and it occupies around 166 Gig on the 500 Gig external drive. That
number will rise to about 350 - 380 Gig by the end of the month, at
which time it optimizes and space used goes back to around 300 Gig
again. On that same drive I have images of around 80 installation CDs
and downloaded programs plus a full suite of video editing applications
and several image editors.
Monthly, since it only gets used for email & our banking work, my
wife's computer is also backed up, encrypted, to the same 500 Gig drive
plus my laptop backup, but it only has an 80 Gig drive, so doesn't take
a lot of space.
I have the alarm set to go off on it at 80% full, (so I can be sure of
being able to defrag, etc.), and it has never gone off.
So, being a rather heavy user myself, you should be able to judge
whether you'd come close to that or not. 500 Gig is quite a bit of data
when it's compressed.
Also; each time it does a back up; does it remove the old one?
That would be a function of whatever software you use to back up with.
Read the manuals for that detail. Mine does and many do, but then
several do not also. My Ghost does it automatically, not sure of True
Image, and I know XPs ntbackup.exe will not do any automagical
optimization.
In the instructions it says to format the drive? I'm confused on that.
Why? It's just like any other drive you would install in your computer
for the most part. Format it as an NTFS file system (which XP uses by
default) and you should be all set.
Anyway, if you're still confused, try to rephrase whatever is confusing
you; someone here will be able to assist, I'm sure.
I'm new at this back up stuff ha.
We all were at one time<g>!
