Question

BACKING UP FILES

I've got to back up my files before disaster strikes. From what I've read doing a mirror backup seems best so I'm asking the experts what is the best external HDD to get ?

My laptop is a HP dv7 3085dx 64bit Hm.prem. with a fire wire (1394) port. I have a two ended male firewire cable that I'd like to use if there was an Ext.HDD having the same port for file transfer. Otherwise, I could use the slower USB 2.0

Thanks for help with this.

Answer
I'd use eSATA

In reply to: BACKING UP FILES

If I read the specs right at the HP web site, this laptop has eSATA which I've used in the past, and it works very well. I'm currently using USB 3, but I see this laptop doesn't have USB 3. I've never used Firewire, but I understand its speed is close to that of USB 3. I'd say that if you can find an external hard drive with eSATA or IEEE 1394, you'd do well. Bear in mind that most of the external hard drives run at 5400 rpm, so I use enclosures with the features I want and put 7200 rpm hard drives in them.

Good luck.

http://forums.cnet.com/7726-7588_102-5554028.html?tag=posts;msg5554028 covers this.

Now about backup. That's more than one copy on more than one device or location. This area has been covered for decades. I began learning about this in the 70's so not much has changed as we move forward except folk want something 100% reliable and unfailing. We're not there yet.

My backup is no less than 3 external drives, synced as I have time and then some usb memory sticks with a select set of folders I can't lose. To top that off I have some items up on Dropbox that may survive destruction of all my backups and sticks.

Regarding speed of the interface.

https://www.youtube.com/watch?v=ZqNWYVJqj3E at 8 minutes has them all up on screen at the same time.

HOWEVER I encountered USB 3.0 troubles over the years and use 2.0 without that issue so I will write that go with USB for now and don't fret too much about 2 or 3. If 3.0 is fine, you'll want that.

Good info all. I should have mentioned that a "mirror copy" is what I am looking to accomplish. I also think my firewire isn't 800 as from looking at the video, the cable ends look different. I also read previously that West.Digital is the better choice for copying to.

For mirror copy, I don't but why?

In reply to: BACKING UP FILES

A mirror copy would have me duplicating the entire drive and having one copy per external. Seems wasteful since I can, with say CLONEZILLA backup my laptop's internal drive to a folder on said external. Since I don't fill my internal drive I can keep 3 backup versions of my laptop on a single external HDD.

And using Syncback or another sync app I can sync that when I feel like it with my backup HDDs.

Most laptops don't have firewire today so it would be a strange choice if recovery is what we are after. USB is ubiquitous today.

My laptop has firewire400 (4pin), USB2.0 and eSATA ports. I guess the thing I want to know is what is faster for transfer excluding the USB. Can I transfer using the eSATA port and if so is it faster than the 1394 (4 pin firewire) port ?

I've done some searching for external drives and haven't found one with 1394 and eSATA. My eSATA port is the 4th USB shared.

Thanks.

So if I understand, I would want to look for a ext. HDD that has a eSATA port and then i need the correct eSATA cable ?

thanks !

Yes

In reply to: BACKING UP FILES

Use care with those enclosures.
Some of them turn into hdd cookers.

Sure. But with eSATA you need power.

In reply to: BACKING UP FILES

I skipped all the work and tinkering. Speed means little if it's too gimmicky.
