Re: [BackupPC-users] Newbie: using a storage server different from BackupPC server

Dan, but what's wrong in having BackupPC on the Web server as long as it's doing the backup to a different partition, allocated only for backup? Thank you, Andrew

best practices says that a backup device should be independant of the devices it is backing up. dont run backuppc on your webserver for production if you plan on backing up the webserver. also, apache is pretty secure if that is what you are running, so as long as your havent broken that security with bad configuration I doubt you will have a security issue.
really, get a dedicated machine for backups. a dual-core system with 2GB of ram is pretty cheap now. A rackmount case and powersupply from newegg is like $100, plus $200 for the mobo and cpu and ram, plus whatever disks you need. 1TB is about $110 right now so you could easily to 2 of those in raid1 for a total price of $520! why waste time and effort and risk disaster by not doing this right?

It's because my only Linux system on the network is the Web server. It's not a problem to back itself up on a local hard drive. The problem I see is that the whole Linux system can be under attack and all the hard drives could be compromised (or even wiped out).
Also I am still not very comfortable running the BackupPC on the Web server because it opens another security door to the outside world and may expose the source code. On the other hand I got a few windows systems on the network with lots of disk storage and not exposed to the Net.
I thought they could be good candidates to carry the backup data. On Sun, Sep 28, 2008 at 7:22 PM, dan <dandenson AT gmail DOT com> wrote:
both NTFS and CIFS/SMB support hard links. Hardlinks work across SMB on remote NTFS volumes.
That being said, I highly suggest you look for other options. This will be a slow, high CPU usage setup.
Dives are cheap. Expand the capacity of your backuppc server and save yourself a lot of headaches. I have to ask....why do so many people insist on running their backup system on some hokey setup? Why even bother backing up the files if you are not going to back them up correctly? It is a false sense of security because when you really need to restore data you have a good chance of something being wrong!
You should really have a backup server with local storage, not network storage. drives are soo cheap now that you can build a 1.5TB mirrored storage array for $380! http://www.newegg.com/Product/Product.aspx?SID=838944-1-0-ARTICLE-0&Item=N82E16822148337
32MB cache masks I/O, a mirror doesnt need to compute parity and the bus speed of the system should be able to tollerate the writes to 2 drives without a significant penalty.

feature to work. Theoretically you might be able to install windows
services-for-unix, export a directory via NFS, and mount that as your
archive filesystem but I don't think anyone has gotten satisfactory
performance that way. For a small setup you might be able to use the
free VMware server on the windows box with the backuppc server running
as a guest. Or, depending on your use for the windows boxes perhaps you
could run windows under VMware to give Linux the native speed - or
dual-boot to let backuppc run at night.
Iscsi would be the obvious solution here but I think the software is
expensive on the windows side. Buying a pair of SATA disks that you can
run in raid1 on the linux box is probably the cheapest approach with
good performance.
