Backup of POOLs

[dpatino1]

I have a couple ZFS pools on nas4free that I need to have backed up efficiently. I'd like to retain daily incrementals and weekly fulls for set periods of time. I have a second san on the same network that the data will be stored on. This is my first venture into non-windows file storage and am trying to figure out how to accomplish this. I tried to use rsync, but was unable to get to do what I want. I read that bacula and amanda can be installed on nas4free, but I couldn't find instructions on how to do that. Is there a better solution or can someone point me in the right direction?

Thanks for those, but the backup script isn't designed to backup to a remote share. I have a windows smb share mounted that I want to backup to.

Alright, so I got a script running that seemed to work when I tested it, but once I scheduled it with Cron, it doesn't work properly. It rsyncs the files and sends an email, but the tar line doesn't work and the log file is empty. Does anyone know what might be the problem?

I ran a couple commands individually and got this

syl-s-030:~# tar -zcfv /mnt/syl-s-012/Backups/CaseData/Weekly/date.tar.gz /mnt/syl-s-012/Backups/CaseData/Daily/
tar: Removing leading '/' from member names

/: write failed, filesystem is full
tar: Write error

Neither of those directoy locations are local to the nas4free box.
