Hi Less,

I'm running it here on an ESX host, too.
Installed as a VM with 2 vCPU and 3.5GB of vRAM as CentOS 5/32bit. The
backup data is stored on a second disk with 1.4TB in size [stored on a
RAID50 array]  (so far 1TB used) now for more than a year (or two
already?). It's backing up other virtual and physical machines (in total
~25 machines), mainly CentOS, but Windows (7/XP), too.

I'm using the vmxnet2 ("Enhanced") which should give better performance
compared to the default ones- but yes you'll need VMware Tools for this.

I assigned the backuppc as paravirtual scsi disk to improve performance
but it appears my box isn't really seriously used. I did block
allignement, too but I'm not sure if this made any difference. I just
used fdisk, switch with "u" and started the partion at 64 instead
default 63.

See the CPU and memory usage:




As I already posted to this list I'm cloning this disk through drbd to a
physical server and take LVM snapshots of the device there so I can
roll-back a month in case something goes seriously wrong.

No issues so far. drbd appears to be a little bit weak in terms of not
doing what you might expect but you'll always be able to recover.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
