[dba-Tech] External hard drive

Is this for Backup?

If so, then you don't need a high-powered drive.  I use a WD Green drive -
it's quiet and cool.  As far as disk reliability vs. brand I don't have
enough experience for a recommendation.

I use Ghost 9 for automated backup.  The weekly backup takes about 45
minutes, and daily incremental backups take about 5 minutes.  These are set
to run automatically late in the evening so I don't even notice. (I think
the latest version of Ghost is 14!)

What size?  It depends on how many weekly backups of your C drive you want
to keep.  If you currently have, say, 50 Gb of data on your C drive, and you
want to keep 4 weekly backups of your C drive, then you'll need at least 200
Gb on your backup drive.  However, hard drives are pretty inexpensive so you
can easily afford more than you need.

Good Luck!
Dan

I'm going to buy an external hard drive -- should've done it a long time
ago.

Any recommendations? I need to buy one locally instead of online -- would
have to make a 2 hour trip into the credit union to deposit funds and we
don't "do" credit. They have them at Wal-mart, just don't know anything
about brands, features, gotchas, etc.

Seems to me like it should just be a question of size versus price balance
-- I'm not expecting this to be a difficult process.
