strange!, I ran a hdparm test at the fileserver (the source of backup) and I get a better performance: [root@qsrpsfs1 ~]# hdparm -t /dev/mapper/mpath0 /dev/mapper/mpath0: Timing buffered disk reads: 622 MB in 3.00 seconds = 207.20 MB/sec ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
