Backup Redundancy Etcetera
Hey. Currently my backup regime is woeful. I have years worth of work on a Windows machine and some stuff scattered across OpenBSD machines.

I have no experience here and I'm thinking about acronyms like NFS, rsync, etcetera. This is for a small number of machines and low rate data changes but if I can find something that's in base, scalable, robust, secure, simple, quick ... :] Please give me some recommended acronyms, man pages, etcetera.

Re: Compiling R from source
I managed to compile R-2.14.0 and .1 from source on OpenBSD 5.0 (i386). Make failed because that two of the tre source files require stdint.h (for WCHAR_MAX definition) but don't include it. I managed to build R by inserting #include stdint.h on src/extra/tre/tre-compile.c and src/extra/tre/tre-parse.c I know this is an ugly hack, and fiddling with the sources seldom is a good idea, but it got the job done... There are some additional issues with the Cairo graphics device, -pthread as a LDFLAG and some of the tests that configure runs, but I'm still working on that. I'll share my findings when I have more concrete answers (later today, hopefully).

It should be robust: able to handle wrong inputs and temporary failures. Right now, the daemon aborts when the table is not known: $ ./pftabled-client 127.0.0.1 56789 nonexist add 1.1.1.1 Server: $ sudo pftabled after receiving packet from pftabled-client above pftabled: ioctl: Invalid argument Or when I supply a wrong netmask (I modifed pftabled-client to allow it, the server should not trust clients to be well behaved): $ ./pftabled-client 127.0.0.1 56789 test add 1.1.1.1/33 There's probably more. pftabled should sanitize that stuff before feeding it into the kernel. AND be prepared to handle failure. I told you in my reply to your code review that pftabled is running on high-volume sites doing several inserts per second without a single observation of this condition. Sure, it may work great for you and a temporary failure may even be very hard to trigger. But why not just handle it instead of aborting?

Re: Backup Redundancy Etcetera
Thanks for the replies. I should have stated I'm after something I can understand at a block level. There are only a few datapoints I care about: * the /etc from a few internal and external OpenBSD machines. * a few other *conf* areas like /var/named and so on from external machines. * either /var/www/virtuals from an external machine or from the Windows machine they were built on. * some personal data from the Windows machine. All that stuff changes little (especially the OpenBSD machines). If I lose a day or so from the Windows machine that's fine. So simple is good. I've read through the ideas and something like dump looks suitable. dump - filesystem backup -f file Write the backup to file; file may be ... ... an ordinary file ... This suggests I can mount a remote partition via NFS and dump to a file there. Is this correct? Can I do this via SSH also? The only other question mark is doing something similar for the internal Windows machine. I could do this manually via ftp but I suspect that will result in it happening far too little. As far as I understand it, Microsoft supply an NFS client via the resource kit and it looks easy to at and script as long as it's interoperable and Microsoft read the RFCs ... Best wishes.

At the very first I tried to boot with the amd64 arch, though it failed immediately at the beginning of the boot process (if I recall and conducted right, it was because of the lacking processor support). Then, I fetched the i386 snapshot from 31.1.2012 and booted. I was able to complete installation now. On the next boot it got a bit further as compared on amd64 arch, though it froze on the acpiec line(see [3]). Power off/power on and 'boot -c disable acpiec quit' helped for the freeze. The motherboard has a wireless ethernet device in the PCI-bus and the card should work flawlessly (have used it in the earlier obsd versions). I also tried with other pci-device, though it gave watchdog timeout errors. Reading the manual page of acpiec and rapid googling of 'acpi embedded controller' did not reveal whether it has something to do with the PCI-bus. Now, I am curious, for what acpiec affects? SUMMARY AFAIK CPU and ACPI aren't fully supported (see [3], B [4]): Relevant lines from dmesg.boot: B OpenBSD 5.1-beta (RAMDISK_CD) #75: Sat Jan 21 00:57:12 MST 2012 B boot -c disable apciec; quit B B cpu0: unknown i686 model 0x36, can't get bus clock (0xc4081400) B B cpu1: unknown i686 model 0x36, can't get bus clock (0xc4081400) B B cpu2: unknown i686 model 0x36, can't get bus clock (0xc4381400) B B cpu3: unknown i686 model 0x36, can't get bus clock (0xc4381400) This is only used for estimating low/high as a speedstep fallback. The problem you alude to earlier seems to be that the processor doesn't advertise long mode in the amd64 case. See ie http://www.astaro.org/astaro-gateway-products/hardware-installation-up2date-l icensing/40935-64-bit-installation.html http://www.mini-itx.com/store/?c=47 64-bit OS Support: Currently EMT64 is *not* enabled on these boards. We expect Jetway to release a BIOS update when 64-bit drivers become available from Intel Intel only documents the MSRs for the first generation of Atoms, perhaps this one is the same. B You don't have EST in cpuid flags though so there is no way for you to test that this does anything at the moment... Okay, thanks for the clarification. I'll try the patch tomorrow and will let you know how it goes. Do you have any clue regarding the acpiec? Regards, Ville Valkonen

Yes, Bacula works well for Windows, it has a proper client which runs as a Windows server and can do VSS. Initial config of Bacula is not very fun, but once that's done you don't have to touch it too much. webacula is also in ports which is a nice web UI, especially good for status displays. There is also backuppc which can do backups using samba as a client, some people might prefer this, personally I don't.

Fortunately I have no problem losing any of these machines and starting from scratch - I don't need drive images or anything, the data I care about is in a few specific areas. For instance the web server, I mainly care about the web sites of which I have multiple copies. I also have a copy of the Apache *conf and I probably have a copy of the /etc changes (rc.conf.local, pf.conf, so on). In a worst case I can re-install from scratch, adjust /etc and copy Apache *conf (or re-write them in half an hour) - all that's not practically rebuildable is the websites themselves.

I'm looking at that now. Part of the reason I want to use base is so that the curve in getting a machine back up is easy. It's kind of what I was looking for but the overhead probably isn't worth it in my situation. Again thanks for all the replies (including off-list). Again I only want to backup data (which is really limited to the Windows machine) and configuration information (which is easily quantifiable and changes infrequently) - simple is probably best. The scenario is so simple that installing software is possibly creating more difficulty. I'll try scripting NFS maybe in combination with dump on the OpenBSD machines and see how that goes.
