I installed BPC a few weeks ago and have been doing testing and setup since 
then and have things working pretty well on several linux, windows, and mac 
clients (ultimately there will be about 15 clients). The server is a Dell 2400 
with a 160gb ide drive, Centos 5.6, BPC 3.1 installed with yum from the testing 
repos. I've added a sata controller and two 2t drives as a raid 1 setup, which 
is what I'll use for real backups. I can't boot off the sata drives, so I boot 
from the ide drive and put topdir on the satas.

I've done some searching on offsite backups as I would like to maintain at 
least a recent copy offsite as disaster protection. DD has been too slow for 
these large drives (I would have to leave it going overnight with no backups 
running). I may go with periodic archives using the BPC archive function.

However, another idea intrigued me that I saw in an earlier posting. Someone 
used a RAID 1 setup but only put in the second disk periodically, then removed 
it for offsite storage. I have three 2T drives, so was considering something 
similar where I would keep a normal 2-disk RAID 1 setup but periodically remove 
one disk and replace it with a prior offsite disk. 

Not being particularly experienced in all this, I was hoping someone on the 
list could offer advice on whether this was a good ideal or not and potential 
pitfalls.

Thanks

Mike
