Hi all,
I have a two drive RAID1 serving data for a busy website. The
partition is 500GB and contains millions of 10KB files. For reference,
here's /proc/mdstat
Personalities : [raid1]
md0 : active raid1 sdc1[0] sdd1[1]
488383936 blocks [2/2] [UU]
For backups, I set the md0 partition to

So - I'm thinking of the following backup scenario. First, remount

First of all, if the data is mostly static, rsync might work faster.
Any operation that stats the individual files - even to just look at
timestamps - takes about two weeks. Therefore it is hard for me to see
rsync as a viable solution, even though the data is mostly
static. About 400,000 files

Ah, you're using reiserfs on here. It may or may not be having
problems with all those files per-directory that you have. Is there
any way you can split them up

Dean, the comment about write-mostly is confusing to me. Let's say
I somehow marked one of the component drives write-mostly to quiet it
down. How do I get at it? Linux will not let me mount the component

Should there be any consideration for the utilization of the gigabit
interface that is passing all of this backup traffic, as well as the
speed of the drive that is doing all of the writing during this
transaction? Is the 18MB/s how fast the data is being copied over the
network, or is it
