Transfer rate between Alt-F NAS drives

[Simon Miller]

I have a 323 and 325 both with Alt-F loaded and working fine. So a couple of question please.

1. What is the best way to copy the contents of one NAS (DNS-323) to the other NAS?

2. I have a win7 laptop plugged into the router and have used this to copy (File Explorer) from NAS to NAS. I am only getting 1.10MB/sec. This has resulted in a 4 day file transfer.  It is stable and progresses without problems, but is mighty slow! Neither of the NAS's show more than 10% - 20% CPU and no swapping

Thanks

Simon

If you are not afraid to use Linux on the command line, then I would suggest using rsync.  You may need to install the rsync package if it is not already installed.  As root on the destination NAS, you would use a command like this:

    rsync -aH sourcenas:/mnt/Volume_1/source_directory /mnt/Volume_1/destination_directory

Where sourcenas is the hostname of the source NAS, and the paths are the appropriate source and destination paths.  You can do a test run by adding the "--dry-run --verbose" options:

    rsync -aH --dry-run --verbose sourcenas:/mnt/Volume_1/source_directory /mnt/Volume_1/destination_directory

Type "rsync --help" to get the built-in help.

Thanks Tom,

I will check out the rsync --help and familiarise myself with the syntax..... 
If I cancel the current windows copy (I am at 3 out of 4 days copying!), will rsync deal with the previously copied files in a "pleasant" manner?

One of the beautiful things about the rsync command is that it will only transfer the files that are new or updated.  If some of the files are already copied with the same timestamp, then it will not transfer them again. This makes it easy to abort the process and start it over again (continuing where it left off), or to just make periodic updates.  It is commonly also used to make backups or mirrored copies.
