FWIW, those are pretty similar to what I've used in the past, with the aforementioned IDE bus issues. The chassis/drive carrier doesn't really add much into the mix one way or another- I've yet to see a carrier that effectively emulates the (removed) drive being online, which of course would pose it's own set of problems... ;-) No bus hangs, but whazt about, "Oh yeah...oops, I forgot I included that mount point in THAT script!" :-)Hello!for whom
I'm looking for a cheap solution to back up a FreeBSD 4.8 machine. Cheap meaning that tape drives are out of question. Even external FireWire drives are deemed a bit too expensive by the folks
I'm doing this research.in one of
This leaves one option I can think of - standard IDE drive
those removable HDD trays. We'd probably use two drives, one being active in the machine and the other being kept somewhere out of the house for safety.<clip>
I personally think this a great alternative to tape, especially given the
low cost per GB of drive space.
3ware cards support hot swapping IDE and there are several hot-swap IDE
drive trays in the $50-75 range. You *MUST* make sure the trays are really
hot swap. Most are not. The ones that are will be very specific about saying
so.
My computer vendor uses these: http://www.amtrade.com/pc/ata133_ide_mobil_hdd_racks.htm
I personally have not used them, so don't blame me if they end up not working as advertised, but my vendor is happy with them. I have also never used that company or its website until today, so I have nothing in the way of recommending for or against.
Another alternative I just found this past weekend... There is a company
making "hot swap" IDE trays, but instead of being IDE out, they're USB 2.0.
It came to my attention that FreeBSD 4.x lacks USB 2.0 support. I used these USB 2.0 trays in a Windows server and hadn't thought that USB 2.0 might not be supported in FreeBSD 4.x. I don't use USB in my FreeBSD servers, so this never crossed my mind.
I'm providing the link to the HDD trays above to show my apologies. :)
Cheers, Brent
