AoE for Backups?

[snowman66]

Does anyone use AoE in production? Maybe for backups?

Recently i build up one aoe storage system for testing.

AoE server:

Ubuntu Server 12.04 amd64
Hardware: intel core 2 duo e6550, 2gb ram, SW raid 1 SATA II, 1Gbit network

PVE server:

pve 2.1
Hardware: amd II x2 250, 8gb ram, 2x SATA II, 2x 1Gbit network

Tests:

Installation of WinXP takes about 6-7minutes to finish. Backuping this VM using snapshot mode
