Direct copy from N66U(USB) to NAS

[TeHashX]

I am trying to figure out a similar script for my rtn66u but to copy one attached usb drive to another on a daily basis. Both drives are ntfs formated for compatability reasons... I think I first need to make sure that the script first mounts my drives according to their uid's...basically I have two ysb enclosures with raid0 and I would like to mirror one to the other every night....any help with this will be greatly apreciated...

Please give more details, are both drives connected to router through usb ports or only one?

Correct, I have two usb enclosures connected to two usb ports on the router...please let me know what details are needed and I will provide. I curently have two 1TB drives in one of the enclosures running in raid1. I am hopping to change it to Raid0 to get 2TB and have this enclosure mirrored to another enclosure with the same setup...pleae let me know of the best way to acomplish thus...I may need to create/enable swap space for something as memory intensive as rsync...

Here is my mount output...

The Media drive is the 1TB storage in Raid1 and Cache is the same type of enclosure but currently with a small drive..I will soon upgrade it to 2TB (Raid0) as well...

First we need to create a pre-mount script (i'm not 100% sure, maybe init-start script, will see after testing)

#!/bin/sh

mount -t nfsd -o rw,nodev,noatime,nls=utf8,fmask=0,dmask=0,force UUID="EA1E40681E402FBD" /tmp/mnt/MEDIA
mount -t nfsd -o rw,nodev,noatime,nls=utf8,fmask=0,dmask=0,force UUID="6C806B1E806AEDD0" /tmp/mnt/CACHE

chmod a+rx /jffs/scripts/pre-mount

Reboot router 2-3 times to see if are mounted as we need, check with "mount" command

If is ok, create the following sync-drives.sh script in /jffs/scripts, this will copy all files from CACHE to MEDIA

#!/bin/sh

rsync -r -l -t -p -g -o -D -h -s /mnt/CACHE/* /mnt/MEDIA

chmod a+rx /jffs/scripts/sync-drives.sh

If you want to run the script automaticaly every day at 21:00, add this cron job to init-start script

#!/bin/sh

cru a sync-drives * 21 * * * /jffs/scripts/sync-drives.sh

chmod a+rx /jffs/scripts/init-start

reboot

I guess this script is better, just in case http://forums.smallnetbuilder.com/showpost.php?p=59842&postcount=5
