Backup Central

Gang, this could end up being off-topic, as it may end up being more about
network routing than backuppc.

But, here's the deal: my father-in-law has a small company (10 computers)
and they never back up. I want to use my new backuppc system to get them
backed up (and offset some of my costs), but I'm not sure the best way to do
that remotely.

They use a linksys router, so I can set up a separate port for each PC and
try to route directly (e.g., 873 to x.x.x.1), but I think with other things
they have going through the router, I'll run out of available ports.
Linksys gives you 10 slots, that's it.

If I recall correctly, linksys lets you route a port (or range) to "255"
which means it routes to all IP addresses in the subnet. That would be a
bit too shotgun; there would be 9 simultaneous authentication failures, and
one acceptance...

Has anyone found a solution that works for anything like this?

Thanks,

Todd

Sure, replace the Linksys device with a Linux box configured as a router.
:^)

Seriously though, if you're looking to back up 10 systems remotely, I'd
advise getting a real router.

If you go this path, look at IPcop. It is easy to administrator for a
non-linux user.

SnapGear firewall appliances are linux-based, and actually pretty cool.
you can configure them just like a hard-disk-based linux box, if you want;
and they also have an idiot-gui that works pretty well.

I think they're around $350; but might be lower now, especially for a
cheaper model (I think we were looking at a fancy one that supported more
VPN stuff. they aren't as cheap as a leftover computer; but on the other
hand, they might be more palatable to a non-geek.

Speaking of VPNs; a VPN set up between your company and his (appropriate
trust relationships in place, of course), would probably be the best
solution for getting to his machines when you want to back them up. (or do
whatever other kind of maintenance).

Todd,

Since most people have responded with "get a new router" sort of answers I
thought I would throw in this more off the wall one.....

You could theoretically set each machine at the remote office to automatically
initiate a ssh tunnel to the backup machine. This tunnel, if done right, would
allow the backup machine to rsync to a local port which goes back through the
open ssh connection. This won't be very reliable and will be a pain in the ass
to get just right with timing and wakeup schedule, etc. But it's possible. If
you need more detail or instructions on how you might do this just let me know.

If you need to hit every machine on their LAN you might as well set up
a generic VPN like CIPE, OpenVPN, or IPSec. Either replace their
router with a similar one that does native IPSec or set it up
to pass through the UDP packets carrying the CIPE or OpenVPN tunnel.
(IPSec doesn't like NAT so you need to run it directly on the
device with the public address). Then it becomes ordinary routing
at both ends because you can pass the private addresses through
the tunnel.

For something limited in scale you might also run a single ssh
instance from your server to a machine behind their router
with several port-forwarding options to let you hit all the
machines. I've been wondering if BackupPC needed any changes
to support this but haven't needed it badly enough to check.
The place I think this approach would be really nice is for
a remote site with a dynamic IP address to be able to start
the ssh session and disconnect when finished. All it needs
is a way to tell backuppc to hit localhost:port instead of
a remote ip address. That would also allow ssh compression
to an rsyncd remote, even on windows where starting rsync
under ssh isn't reliable.

Yep, this is probably the correct solution in this case. With a VPN
running you will have access to all machines on the remote end using
existing hardware. You may have to use one of the machines being backed
up as one of the VPN endpoints if the Linksys doesn't support it.

There have been a lot of good suggestions. An alternative is to
simply locate a BackupPC server at the company and use the LAN rather
than WAN/VPN. It will certainly be faster. The drawbacks are remote
administration and no solution for disaster recovery if all the PCs
and BackupPC server are destroyed.

I have a customer with two offices that backup to each other. I have a
BackupPC server in each office which backs up the local office. Then I use
rsync to mirror the BackupPC partitions to the other office on another drive
mounted on a partition called /otheroffice.

This happens once per day and after the full backup completed, each day
takes less than 12 hours and runs overnight. It works pretty well.
