ReadyNas backup and restore

1) With broadband connections at the office and home, what sort of throughput can I expect? At the moment I'm getting around 150MB copied per hour which seems rather slow. Does the NAS CPU limit the transfer speed or some other setting? I'm using DynDns on my home router.

The maximum throughput will be limited to the slowest uplink speed. Most DSL & cable broadband connections are asyncronous, meaning that they are great for downloading, but slower for uploads. In my neck of the woods a typical home DSL circuit is 7 Mbps down and 800 Kbps upstream. Cable is a bit better at 10 Mbps down / 1 Mbps up.

In your case, it looks like you're getting ~333 Kbps, which isn't abnormal, depending on what level of service you've purchased.

2) I have selected to compress files for faster transfer. Which is better, doing this or turning off to save NAS CPU cycles?

I generally use compression. As noted in my answer to #4, use the backup Duo to pull data from the primary. This way, the backup unit will have to make all the delta calculations and compression and the primary Duo's CPU won't be taxed.

3) Once files rsync'd to the home NAS, how do I restore files from my home NAS back to the office? I have selected not to delete files remotely when deleted in the office. Do I FTP into the home NAS and transfer back that way?

Yes, you can use FTP or ReadyNAS Remote or WebDAV, etc.

4) I have about 150GB of data that I want to perform rsync backup on. Obviously, the first backup would take days if not weeks, so is there a way to copy the data in the office to the home NAS and then just do rsync incremental backups thereafter? I can't see the option NOT to do a full backup when creating a backup set.

You can put both on the same network and then create an NFS backup job to pull the data from the primary unit to the backup. Once the job is complete, modify the backup job to use rsync (don't create a different backup job or it will have to backup everything again).

NFS can copy data at about 45 GB per hour vs. much much slower for rsync.
