Rsync tuning on low power NAS

grimthaw · 12-22-2013, 02:09 AM

Hi.

This is my first post on this forum but i have lurked on it as a guest for some time and found it quite informative.

I have a QNAP TS-412 with a Marvell processor (single core arm) with 256MB of RAM that is running a proprietary embedded Linux operating system called QTS. I have asked for some help over at the QNAP forums but

The NAS has fallen over when the RAID 5 array corrupted after my 2 year old nephew went nuts on the power button. I have followed a procedure to get the array working http://unofficialqnapsupport.net/?page_id=1336

Most of the conf files in the system are corrupted but the data appears to be ok. I have SSH access via terminal and wish to move the data via rsync to another NAS.

I have a slight wrinkle with my rsync command:
when i use this one
rsync -Pre "ssh -c arcfor -o Compression=no" /share/Multimedia owner@192.168.0.252:/volume1/Multimedia

it restarts from the beginning for the transfer each time

when i use this one

rsync -uPre "ssh -c arcfor -o Compression=no" /share/Multimedia owner@192.168.0.252:/volume1/Multimedia

ssh is introduced into the transfer again.

SSH not being in the transfer is important it slows the transfer by a factor of 4 (Marvell/256MB ram). Any help on this would be appreciated.

Thanks.

Drop the ssh invocation? That's what the "e" and ssh stanza does. Is the rsync server minimally configured and ports open (if there's a firewall) on the other host? After that, turn off the rsync server.
