My main desktop PC is running Linux Mint 14. The motherboard is an Asus p6t, i7 930, 24 GB non-ECC. My /home partition is mounted on a 3ware 9650-4lp hardware RAID controller with a 3 TB RAID5 array. I exported 3 TB on my freenas box that I'm mounting locally over NFS that I use as an rsync backup target.
The issue: I used to have two partitions on the RAID controller and rsyncs from my 2 TB /home partition took about 2.5 hours. But now that /home has the array to itself the rsync takes about 4:40 to run. This is so slow I'm only running it once a week.
I came across an m1015 on Amazon for cheap, well ok $129, and I have a couple of spare 1 TB drives laying around so I can do /home on a RAIDZ2 volume in the Ubuntu box. So I'm thinking when 14.04 ships in April I can install zfs-native on Ubuntu and use zfs send for the backups. I can't imagine that taking almost five hours to replicate.
The question: The Asus p6t does not support ECC memory. Wife is pregnant, so gutting the box for shiny Supermicro bits is not in the cards right now. Is the lack of ECC support enough of a liability that it would outweigh the increase in backup performance?
BTW, I'm using Virtualbox for the virtual machines. The script finds which ones are running and pauses them before running the backup, then unpauses when completed. It was a little tricky to get working so I'm including it in case someone finds it useful.
