ReadyNAS Replicate or Rsync or TheForce
Hello everyone again,
Since I am stuck with the capacity of my maxxed 3200's, I need to get the backups right.
I have tried Rsync and now trying Replicate. Replicate looks slower....is the data actually moving from NAS01 through the interweb and then down to NAS02?
I have each 3200's NIC's team XOR (3+4) on Cisco SGE2010's (LAGed), both on the same switch.
Rsyncing 9TB of artwork ran for 24hours which I cancelled because it just seemed too long. I then checked the folder and it only showed 1.8TB of data.
Any suggestions? anyone have a better idea for teaming?
Thanks again!

- NFS for the full backup the Rsync for the incrementals would work better than doing Rsync for the full backup.
If the NAS units are on the same LAN the files should get copied over the LAN using Replicate. - Thanks mdgm....
I have the NIC's teamed, and appropriate LAG on the switch. Both 3200's on the same switch, no traffic on the switch other than these two NAS's for this purpose. I ran Rsync for 24 hours and canceled.... Ran Replicate for 12 hours and canceled.... its only 11.8TB.
Just started an NFS backups as you suggested.
Are my expectations too high? - 1 TB an hour is higher than your total link speed (it works out to 2.4 gigabits per second). So I'm wondering about the last step.
Generally you can get 100 MB/sec sequential file transfer with NFS on a gigabit interface. That's 350 GB an hour.
If your teaming can balance the traffic, then you could possibly double that if the receiving NAS has the horsepower to keep up. Though even L3+L4 hashing will put all the traffic on one link unless there are multiple source or destination ports being used in the transfer.
So perhaps your expectations are too high. - My expectations on everything are too high....ask my kids :(
Thanks for the info.....I'll let the NFS run then switch to rsync.
