Best Way to Back up
I have been reading about many different ways to back up data. Is
there a popular method that is used today? I am trying to decide on Tapes or DVDs or any other method. Is there a convention method that is used today? I would probably be backing up the system once a week. I would be backing up somewhere around 10-20GB. |

I've been making backups for over 20 years and have progressed from floppies
through tapes to HDDs in mobile racks. I currently use 2 160 GB HDDs, each of which fits into the mobile-rack frame installed in my computer. I can keep the backups offsite and in different locations, and I can have as many as I need. The only caveat I can think of is getting a high-quality all-metal mobile rack with a large bottom or multiple fans for good cooling such as the ones made by Kingwin. I'd also advise against Maxtor drives for such use because they run quite hot as opposed to Samsungs that run significantly cooler. Note that these are the only two brands I'm familiar with, so ask around to see which drives run cool. wrote in message oups.com... I have been reading about many different ways to back up data.

Maxtors run hot to the touch; Samsungs, warm. I've had 2 Maxtors die on me almost certainly as a result of heat and poor cooling. How much power do the Samsungs consume? The Maxtors? No idea.

Ubiquitous fledgling
Outright I agree that backing up to external USB disk is the most convenient method, primarily because of speed, and because you do not have to baby sit the backup to replace media. Some other questions you need to ask yourself: * How frequent you want to take the backup (hourly, daily, weekly)? In other words how much work are you willing to loose? * How much backup history do you want to keep (few days, weeks, months)? Note, the more backup history you retain, the more time you will have to notice a corrupt/deleted file before it propagates all over your backups. * Another question is the number of media. As suggested here do not use a single backup disk, use at least two, and try to rotate them as frequent as possible. That way they all will be as up-to-date as possible. Anyway, try to keep as much backup history as you can, and take as frequent backup as you can. You may also want to look at our solution at http://www.datamills.com that has several nice features to reduce the required attention, backup space and backup time, while maximizing retention period and backup frequency. --- Joe Rom King http://www.datamills.com Back up and restore from incremental archives that go months back without multiplying the backup space. |

One problem with two is that if one fails during backup, you cannot make another backup at that time without loosing your only older one. Use at least three. Arno |
