Am planning to back up about 40GB's of data to a 150GB external hard
drive. Am assuming that on subsequent back-up's that the data nis
either over-written or replaced rather than another 40GB chunk od
data onto the drive . Yes? No? Thanks.
Well, maybe, maybe not <g>. Just keep your eyes open. It does not depend
solely on what you use for a file name.
First you want to do a Full backup, I assume; everything on the hard
drive. Taht's one of the choices given to you.
Then after that you want to do "incremental" backups, or in other words,
just back up the things that have changed. Incremental is also a choice
provided to you.
Don't forget to read up on Restore, too while you're at it! Backups are
no good if you don't know how to restore them. And lastly, become familiar
with ASR (Automated System Recovery), or how to recover from a completely
trashed hard drive C:. You use a special boot disk that backup makes, and a
related set of backups you have on CD or other external storage media. It's
pretty well explained, I think.
If you look in the backup application's Help you'll find excellent
discussions of the various processes and how/when to use them. It's fairly
well written, but in MS-lish, so ... ymmv <g>.
There's also a pretty decent article, with good definitions, on it at:
