Hi Russell-
Can you give us a command to call (using bonnie++ binaries) that will
give a more real-world test of filesystem and disk performance? I'd
like to see how bonnie++ differs from hdparm in results.
Thanks-
Eric

On a pretty loaded system with a 3ware 74xx series card, we're getting:
# hdparm -tT /dev/sda3
/dev/sda3:
Timing buffer-cache reads: 128 MB in 0.65 seconds =196.92 MB/sec
Timing buffered disk reads: 64 MB in 1.44 seconds = 44.44 MB/sec
This seems to be more in-line with expectations.

Yes the disk reads is a more realistic real world test :
/dev/sda5:
Timing buffer-cache reads: 128 MB in 1.23 seconds =104.07 MB/sec

Hi,
If you want to backup your mailserver to another machine, you should use netcat, cat
for eg.
cat /dev/hda1 | netcat -l -p 1234 << do this on the mailserver
netcat 1234 > /backup/backup.img << do this on the backup server
Cheers,

I have 2 ideas:
You can use the same disk drive as the primary, and do a 'dd if=drive1
of=drive2' , that will make full backup
Or, the way i do on one of my servers, use rsync , i use it this way:
rsync -logptvr /etc /var /usr /home /backup0/serv
(the last parameter is the directory where you mou
Can anybody pls help me on how to have a full back up of a Mail Server
(Running on Debian and Exim) ... I want to have a full backup of the mail
Server on a different drive with all the users and directory permissions
the same with the original server.
Thanks
