Initial vanilla kernel support went in last summer (2.6.18 IIRC).

Don't ignore eSata (external sata) for the same purpose. (If you don't have an eSata connector you can get a Sata <--> eSata cable for $10 or $20, just be sure it is 300 Gbit/sec rated.)

I have 3 spare ports on this 3ware raid card that I can use, just no more room in the tower for any more drives to be mounted. This is an older machine ( 3 or 4 years old) that does not have esata or sata on the motherboard if I remember. I'm just looking for a faster backup device then tape or network backup from another machine. Do you think that using one of the spare ports on my 3ware card with the sata to esata cable will work ok or not. I have a spare pci slot that I could stick another sata card into the machine also.

I would be unhappy if the 3ware card did not work well with an eSata setup via an adaptor cable but I've never tried it. I just posted that Sata has hotswap now. I'm not sure the 3ware driver would support hotswap of a JBOD drive. Obviously it should let you replace drives in a raid array without powering down. I'm just not sure they handle standalone drives coming and going. FYI: After you plug in the eSata card you normally have to initiate a drive scan. I've forgotten how that is done. I think you echo a value into a sysfs field. I do not think I will hot plugging the drive, I would be leaving it attached to the server an then move it to a new machine if I had to do a restore on a new machine. I now have one space drive plugged into the 3ware card, making it a total of 5 drivers on the card in a raid 10 configurations ( mirroring / spanning). I might play with using the 5th drive as a backup driver til I can get me an esata drive here next month. I have found one from iomega besides the one you told me about for around $290 from one of the places I get hardware from ( synnex ). I much more prefer the seagate drives since that is what I use most of the time when I buy new drives. I can also get an esata to sata cable from them for around #12 to $15 or so. Think I will order one of the two drives an plan to put it into action after I return from a trip out to LAX for a conference I'm attending next week. Thanks again for the info. I have also found out that this machine has a newer motherboard in it with 2 free sata ports on the mb so I have 5 total ports free for sata. I just need something faster to backup onto for my backups, that was what got me to thinging of the firewire drive.

Jack, I just got a hard drive enclosure that you can use with both firewire and usb. I attached a 760GB hard drive. It is very fast. I have not measure the real speed. The box says 400mb/s. I am using SuSE 10.2 and just plug it then partition and format the disk (I used yast) and I back up the whole system. It is great. The enclosure is in sale until next week I believe. The price is 39+ dollars and there is a rebate of 30 so it cost $9.60. http://www.microcenter.com/byos/byos_single_product_results.phtml?product_id... I got in the center but you may be able to get it on line. If you want hurry up. They have OEM drives very inexpensive but only up to 250GB. For what I understand you can daisy chain the firewires so you may want to get 2 enclosures. They have all the cables. Hard to beat. The enclosure has one port for usb and 2 ports for firewire so one in, one out. Ciao -=terry(Denver)=- PS: it is my first experience with firewire under linux. Just as easy as usb. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Seagate for one has a couple of eSata 300 Gbit/sec drives. They should be much faster than even firewire. (3x per the datasheet).

Interesting. I see it comes with an eSATA PCI card but they don't list Linux support or the chipset. Do you happen to know if the card is supported by libata?

It's also curious that it only comes with a one-year warranty while the drive itself would come with a five-year warranty.

Cheers, Dave

No idea. I was just googling to make sure an eSata drive was readily available before I recommended using one.

I use this on my machines that have usb 1.1. However for machines that have usb2, you will find that usb is faster than firewire.

I backup using BRU, (paid - but worth the price) and it builds a compressed tar-like file directly on the target drive, rather than a file by file copy. This allows me to stack several complete backups onto an external drive. http://www.bru.com/

I have one unit that has both a firewire and usb2 port. Either works fine, as long as I plug into a usb2 port on the computer.

I have another Western Digital "MyBook" which is usb2 only. These are really great drives by the way. They use intelligent power on/power off, and work on windows or Linux. Once my BRU backups exceeded 4gig I had to repartition the drive a smarter file system. I just put Reiserfs on it because imho its faster than snot.

Ok is this better on the quoteing Randall I found where it was at in outlook 2007 an fixed it. 9 I'm forced to use outlook for now ).

Thanks for the info John, I have a seatgate driver that I play with that is usb an I think firewire , Might have to hook that up after my trip next week an see what happens with it. I need to checkout Bru I have played with the free version in the past with a tape drive. Thanks for the heads up on 4 gig file size, My backup files size now is at 11 plus gigs an growing. I archive every three months an do not do a backup nightly on the airchive stuff so I can cut my files size down.

I've been using rdiff-backup for my online backups since last summer. I've had only good luck and it can be used in both local mode and client/server (wan or lan links). The code is all python (iirc) so the clients run in most environments. And the mailing list actively supports linux / mac / windows clients (not sure about servers). And it has been part of the Suse distro for several releases. The way it works is to keep full copies of all the files being backed up and then a series of deltas to get you to older versions. The only time it really falls down for me is if you rearrange your filesystem structure, or even just rename a directory. rdiff-backup will see it as you having a whole bunch of new files that need backing up.
