BackupPC Backing Up FreeNAS (BSD)
by nooobeee from LinuxQuestions.org on (#59S5H)
I am having a tough time setting up BackupPC to backup FreeNAS to a debian box hosting BackupPC. I've been picking away at individual challenges for a couple days now and am just hoping someone here can help expedite some of this.
I have backuppc setup on a debian vm. I have setup a BSD user and enabled key login so rsync can be remotely invoked (unsure why BackupPC remotely invokes rsync rather than just running rsync itself but that seems to be how it is by default). I can successfully perform the following commands from debian without issues:
Code:rsync -v username@FreeNASIP:/mnt/zfs01/foldername/ /mnt/backupsI suspect the problem is with backuppc's syntax differing from what BSD expects. Does anyone have something like this setup and working that I could script kiddy off of as a framework?

Done: 0 files, 0 bytesI've replaced several variables with explicit syntax to work my way through issues. The problem may be just my inability to wrap my head around what's going on here. I think it's something to the effect of:
1. Debian initiates ssh
2. Debian connects to FreeNAS
3. rsync is invoked on FreeNAS
It seems to me this is an issue with the $argList+ option. Obviously these are modified and can be overridden in the machine config using the Arguements override. But I don't know what the + is at the end and I also don't know how or why there is a
Code: .in there.
Any tips, suggestions, or clarifications would be appreciated.
