Rsync tuning on low power NAS
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.
