FreeNas Remote Backups

So I love that ZFS allows automated snapshots and that my FreeNas box is set up with a 3 disk Raid.  However, I’m paranoid.  What if the house burns down, or someone breaks in and steals all our computers?  A smart guy would have a remote backup somewhere.  So, I decided it was time to get my remote backup groove on.

I know that you can do a ZFS replication to another FreeNas box. The issue I have with that approach is that you have to replicate the entire ZFS volume. I needed something more granular.  So, I busted out some python and started working on a remote backup script. To give credit where it is due, my brother helped me get started…so thanks big brother. 

*Disclaimer*

I am not a programmer.  This code and instructions are provided “as is” with no warranty, promise that it works, promise that is won’t melt your computer or even cause the end of the World.  Use at your own risk.

The general overview of how the remote backup program works is like this. First the program connects to the remote computer and rsync’s all of your files. It’s setup so that you can have four different sets of remote backups all running on different days if you want. I personally am only using one backup that runs every day. Next, it determines the disk usage of the remote backup disk. It then calculates how long the backup took. Once it has all of that done, it compiles an email with a general status at the top and the details at the bottom.

So here’s the setup.  FreeNas 8.2 at home.  Mac Pro running OS X 10.6.8 at work with a 3TB drive attached. (This probably will not work “as is” if the remote machine isn’t “unix” based) I already have ssh access to the work computer. Decided the best way to push out the files was to use rsync. I really don’t care about old versions of my files on the remote backup. If a person did care about that they could use rdiff-backup…or duplicity if you wanted the backups to be encrypted, but that will require some changes to the code.

Alright, alright, alright. So before I get too far off coarse. This will be pretty easy for other people to do. I’ll break it down into steps.

  1. Create a user on your FreeNas box that you can ssh in to. Create or copy your ssh keys into the .ssh folder of your new user on the FreeNas box. Then copy the public key of the pair into the authorized_keys file on your remote computer.
  2. ssh into your FreeNas box and create a file named config.py  The easy way to do that is:
    vi config.py
    

    Then download this file and make changes to the config options so they make sense for you. config.py (I’ll paste this in as text at the bottom) The program is designed to allow 4 different backups to be done…hopefully that will be enough granularity. When you are done setting it up, copy it and then paste it into the config.py file you just created on your FreeNas box. When you are done pasting, type :wq to save and quit out of vi.

  3. Now you need to download the FreeNasBackup.py file.(I’ll paste this in as text at the bottom, but use the download as white space matters in python and WordPress has messed up a bunch of the code)  This file shouldn’t need to change…unless you want to improve it ;) Get that onto your FreeNas box the same way you got config.py there. ***IMPORTANT*** config.py and FreeNasBackup.py need to be in the same directory.  You can change the name of FreeNasBackup.py to whatever.py you want…but config.py needs to stay named config.py.
  4. ***MORE IMPORTANT STUFF*** I highly recommend that you do an initial backup to the remote drive locally before running this program.  Now, on the FreeNas box, cd to the location of the FreeNasBackup.py program and then type (It is going to run for a long time):
    python FreeNasBackup.py

    With any luck, the backup will run successfully and you’ll get a status report email with the results. It should look something like this:

    Remote Backup - Users: OK
    
    Checking remote disk usage: OK
    
    Backup Runtime (hh:mm:ss) 0:19:49

    /dev/disk14s2  2.7Ti  940Gi  1.8Ti  34%  /Volumes/RemoteBackup
    
    --------------------------------------------------
  5. log in to the FreeNas webGUI and setup a new cron job to run your shiny new remote backup program. The user should be set to root.  The command you want is something like this: python /mnt/some/directory/FreeNasBackup.py  Set the criteria for how often it runs as you wish.

Well, that’s pretty much it.  I’m sure I’m forgetting a bunch of stuff…so I’ll fill in the blanks if I think of them.  Let me know how it works for you. Good Luck.

Also, if you find this super useful, I wouldn’t turn down paypal donations.

  1. Hi Joe – Thanks, I’ve seen http://www.rsync.net, however, the annual plan pricing for 1TB of storage is pretty steep ($1800) in comparison to CrashPlans+ “unlimited” service ($50 annually). Additionally, CrashPlan offers the initial seed service, where they send the 1TB USB drive to you, I send it back with the data, saves the headache of the initial transfer.

  4. hi joe, thnx for posting this. would i be able to ask if you think my set up will work if i follow your instructions.

    i have a freenas 0.7.1 at home. i have a tonido plug, which is a commercial product with linux as underlying os, which sits at my in laws house.

    i want to essentially create my own offsite automated backup instead of using crashplan. the plan is to rsync files from freenas box to the tonidoplug over the internet.

    so what do you think? if i follow your steps exactly, will this work?

    i’m not a prgrammer. thanks for your time

    • Thanks for the nice comment. I’m glad that someone is finding it useful. I know some of the posts are a bit rambling with a lot of important info in the comments. Never claimed to be a professional writer :) Really using this blog as notes to myself more than anything else.

  5. Hi Joe

    I completed following your guide and ran the python script as the last step. This is the error that I got. I have no idea what to do next. Any insight is much appreciated. Thanks.

    • What version of FreeNas are you running? On 8.3.1 it looks like python is 2.7. That could be the issue as it looks like you are running python 2.6. I guess I would start with either upgrading FreeNas if you aren’t on 8.3.1 or manually upgrade python to 2.7 using ports. Let me know if that helps.
