hot swappable esata drives

We have an idea for a backup box that involves using eSata drives for keeping a mirror of a backup drive and being able to take it off site and rotate through say 4 on a weekly basis. I have never messed with eSata before and I am wondering what kind of support I can expect in the linux distros for it. The 2 distros I use most are CentOS and Slackware. I am sure that eSata support is probably not hard to find but I am wondering what is needed to use the hot swap feature.

Any input or ideas are welcome!

Not sure how well one can say hotplug under Sata. But since the drive is under the generic scsi interface I would assume you can remove the device with the echo command and then unplug. Then plug in another and maybe hal and udev might take over. If not there is a little script called that can detect new scsi devices and add thier /dev/sd device block as needed. I need to get to my other machine to pull up what I am referring to on the use of echo to remove a scsi device ID. Typing ' cat /proc/scsi/scsi will show what you have seen through the generic scsi interface of the kernel.

Thanks for that. I am weak when it comes to hardware and linux so bare with me if I use wrong terms or what not =)

All we would need is a way to spin down and power off the external drive and then plug in a new one and power it on and spin it up preferably on the same device. The eSATA drives will function as data mirrors and we will rotate them off site.

The OS we plan to use is CentOS 5.1.

If what you are suggesting is the best approach what would you recommend to read?
