What is the consensus on using external hard-disks as back-up media. There is a LaCie External 250 Mb for £100.00. Seems like a bargain. Drag is that they need separate power supplies. Are these a worth-while investment?
Imho yes. I use a usb external drive 120gigs. I like the fact that it has its
own power supply. Less drag on your system. I leave mine off until I need
it. When I get done with it I turn it off. I like that versatility.
They are totally independent of your system, you can power them off and protect your backups, they're portable, and did I mention they're handy as hell! I have a bunch of them here, and my customers use them as well.
I guess everyone has different views on this. I have 2 external hard drives and I can't remember the last time I had used them. I usually just back everything onto a separate server. But I guess if you don't have that kind of redundancy equipment around, external drives would be great.
The two external drives I have are just 40GB and 120GB laptop drives in an external cases. The do not require any external power supply because they draw power from the USB ports. However laptop drives can be pricey.
Joe, I also have a separate server that just sits there for backup from the other machines, and I have a daily automated backup. I also do data backups to a different physical drive on this machine twice a day.
OTOH, when I backup to the external drives, I then turn them off, so any data on them is 100% safe from corruption. Also, it gives me a warm, fuzzy feeling to have that extra copy of my data. YMMV
For folks that just want a reliable backup device, an external hard disk is about as cheap and convenient as it gets.
