Damn! Yes I meant to type rsync, not ssh. I blame this free keybroad.

wouldn't work, no reference to BackupPC does not exist on either freenas server

would be
/mnt/poolA/linuxBackup -> /mnt/poolC/linuxBackup

also did you mean

Code:

rsync -aH

rather than

Code:

ssh -aH

cos

Code:

ssh: illegal option -- H

or do you and your army for free electrons have some super duper ssh that we mere mortals could not possible comprehend ?

But thanks for the advice

That's exactly what the command I posted does

I was going to create a cron job on the backup backup freenas server (the one that isn't mounted) to rsync. Takes some of the effort of the backuppc server

rsync doesn't care whether the remote or local end of the connection is the source or destination. As long as you have the appriate SSH public keys on the other box, you only need

Code:

ssh -aH user@otherbox:/var/lib/BackupPC/ /BackupPCbackup/

Ok let me see if I have got this right...

I have installed backuppc onto my new ubuntu server. Now I mount the 4tb freenas share (via nfs) to /var/lib/BackupPC

Then all the backups will go there.

What happens if I want to backup the freenas server to another freenas server (I did want to use zfs replication but I can't get it to fully work )?

You could start with LXF125.

+1 for BackupPC.
We back up all of our servers (Windows and Linux) to a Ubuntu server with a 2TB mirror running BackupPC, which has the off-site backup disk archive attached as well.

I'm an Amanda man myself!?

Amanda is command line stuff unless you go commercial with Zmanda. I found Amanda tricky to configure but eventually when you get your head around some strange concepts and configure it correctly it just works and does the right thing. I have found it entirely reliable over the last five years or so. I do suggest that you use Genes helper scripts to backup the indexes as this is an Amanda weak point.

Restoring is easy but a bare metal restore is not, so you would need to practice that. If its for Windows admins then I'm afraid I think you are on a loser with this one unless you go Zmanda which has a web based gui.

Although I mention all the negatives above the big positive is that it has practically required no maintenance over the years I have been using it.

After trying various systems, I am now more than happy with BackupPC. It is space-efficient when backing up multiple computers as hard links are used for duplicate files, and as it is all controlled from the server, no software or configuration is needed on the machines to be backed up beyond ensuring that SSH is running.

1) Determine what needs backing up and how much space you need for it.
2) Put in some cronjobs:
2-1) once a week: scp the entire data-set to location X
2-2) daily: rsync changed data to location Y
3) make sure the backup locations are not accessible by normal users

When a restore needs to be done, scp the latest known correct backup from location X, then rsync from location Y manually. When you put in the cron jobs, make sure different times are specified for each copy action, to avoid clashes and network congestion and make sure enough time is given to complete the job. Also, put in place a system for removal of older backups, discuss the retention period with the 'powers-that-be', making sure they understand more retention means more costs and overhead...
