Re: [Devil-Linux-discuss] DL and Motion

Gudy, I can't speak for bacula, but what about backing up from your DL 
server to another machine over ssh?

    * rsync: this is good for simple backup and it might also be
      possible with DL to use some of the scripts built around rsync
      such as rsnapshot
    * rdiff-backup: sadly this is not supported directly by DL (which
      lacks the required librsync library), however it is possible to
      run it on a remote machine (on the same LAN) which first mounts
      the source directory (located on your DL server) using sshfs
      (which in turn requires fuse). I use this for our daily backup
      from DL to a Ubuntu-based backup server. rdiff-backup (and its
      derivatives, including my TimeDicer) provide a full backup history
      so you can recover previous file versions and deleted files, and
      it does so in a space-efficient manner. (It is also, like rsync,
      bandwidth-efficient if it can be run on both source and
      destination machines, but obviously that wouldn't be the case here.)

I'm assuming that it is only data that you need to backup, because one 
of the beauties of DL is that backing up the configuration is simple 
with save-config.

I have recently been trying to tackle the situation of a DL server 
failure when no tech wizard is around to fix the problem. I created a 
similarly-configured DL server on the same LAN, with a different name 
and IP address, and then wrote a couple of scripts one of which 
regularly mirrors the main DL server data to this standby machine, and 
the second of which can be used by a non-techie in emergency to switch 
this mirror to being the primary. I would be interested to know how 
others approach this problem?
