The medium is regular sata2 hard drives with ext3 filesystem on a dedicated backup machine with quite rusty debian (etch) linux. Most backed-up systems (that I care about) are actually freebsd 6, the rest are linux. Most stored backups are 20-60 GB. Main bottleneck here is the network - quite laggy 100 Mbps link, because this backup server is quite far and isolated from the rest. Also it's completely inaccessible from backed-up machines, aside from reverse tunnels, which I rarely use as a dirty hacks. And this link has tendency to go down every once in a while, interrupting ongoing transfers. That said, nightly backup should always be available, so the backups are actually created on hotswap sata2 drives of each individual machine and grabbed by backup server over ssh and, in some cases, nfs. These days the scripts on the backup server quite frequently (10-50 times a day) connect to the other hosts and receive requests for certain paths from stored backups. So they parse backups with tar picking out given paths and pushes them back, as requested. Needless to say, it is slow, hence the need. Well, that's probably a bit more verbose than necessary, but the point is that (I believe) the backups should be created right on backed-up systems' hard disks, so: 1. Have random access to backup storage. 2. Prolonged io/cpu load is a bad thing. 3. Compression (at least of gzip ratio) is a must, because of limited storage on backed-up machines. 4. In-backup seek times should be lower than tar (which is scanning the whole file). 5. I write py scripts for a living, so the question is really in a backup format - transfer and storage structure is not the issue. Easiest thing I've thought of is just to generate tar index on first archive pass and then just skip to the recorded point in ungzipped stream, feeding the rest to tar, stopping when necessary, but there's no point to debug and maintain this system if there are better solutions already. If hard disks, do you have a separate machine for storing them? If so, BackupPC may suit your needs.

Sync is indeed a great idea, which should save tons of time and resources, but some compression should still be necessary, even on backup server, since most content should occupy 2x-10x space when unpacked.

Instead it seems you wanted to take me in a direction contrary to what I was asking. However, in rereading my original post I can see your point of view so I apologize profusely. I don't have any TVs with HDMI. We don't watch TV all that much. If we do it's NetFlix DVDs or NetFlix via the Roku box. Myth just records junk mostly and I need to display it on the TV which has an extra S-Video input that I currently use. My wife doesn't play games, doesn't need 3D or anything fancy. Nice to know. I guess what I'm saying is who are **you** to decide what makes sense in my life or how I should spend my time and money? I think you miss-read my intentions. I was not really insisting on what you do, just trying to provide a workable path towards resolution. I'll give you the benefit of the doubt (trying to be polite here) and assume you are frustrated, due to your driver not being pulled forward in the new kernel stuff. Being nasty only discourages folks from help you, imho. I did not see anyone else bothering to help you, or discuss your options. Well, it is true that you're the only one who has answered so far. The post hasn't been out there very long so I didn't read anything into that. On the other hand, please consider that I asked about Nvidia S-Video because I have 3 working Nvidia GPUs, 1 working ATI GPU, two broken ATI GPUs and one broken Intel GPU. With those statistics which vendor would you expect me to choose? If you're not interested in answering my question then why not simply stay silent instead of this? If you want to start a thread of your own about the merits of that card then feel free to do so and then you and others can go down that path. Um, looking back at the email, you suggest you are spend new money. You did not state that you hate ATI and only nvidia solutions are viable. In fact you talk about Intel and ATI video hardware. Nvidia, imho, is the most aggressive company at deprecating old hardware. I know I have several Nvidia cards sitting on the shelf, but, all of my ATI cards are mostly usable... (note ymmv). Agreed. I was not as clear as I could have been, although I think the title of the thread might cause one to exclude other vendors, assuming you will give the OP the benefit of the doubt that he/she/it/thing knows what they want. I think you actually didn't, but I can accept that. That said, I have still received no info on this list that answered the original question. I asked the same question this morning on the Myth list and got three targeted answers immediately, so my problem is solved. Thanks, Mark I'll consider ATI again when 100 people on this list say it's the best thing since sliced bread

I'll try to put together an xauth command, but does anyone know what happened here? Usually you just enable X11Forwarding and you can use it right? Hi, I seem to have missed a couple of posts in this thread. Have you got xauth installed? When I set up a new machine recently there was a missing dependency - I _think_ it was xauth. I installed a base system + knode + mozilla. I never installed X11 explicitly, as I never log into this machine locally, only use a couple of X11 apps remotely (because those aren't available on my Mac). I'm not sure if X11 itself was installed or only some X11~ish libraries, but there was definitely a dependency missing as a result of the way I installed. Unfortunately I didn't file a bug. Secondly, when you ssh in, you need to use `ssh -Y hostname` in order to enable ssh forwarding. Hope these observations are not unhelpful, Stroller.
Re: [gentoo-user] [OT]UPS battery dead?
Unplug all your electronic devices and plug in a lamp with a 100 Watt incandescent light build. With the lamp on unplug the UPS from the wall and see what happens. If the battery is dead it won't last all that long. Gave ~5 mins. So I let it charge for 24 hrs now it gives me 36 mins. Which is wierd; what happened to all that charge? I haven't had to use it for 6-7 mons. Isn't the unit supposed to stay topped-up? Another thing: When I do the remove-the-usb-cable test I don't see the communication lost error in apcupsd.events until I switch the dial-up off and on quickly! In the conf file I have DEVICE: /dev/ttyS[0-3] because the default, /dev/ttyS0, locks out the modem. But why does the UPS need to know about serial ports? It connects by this funny RJ-45/USB cable.

(Really rough ideas - just numbers, etc. Don't take it too seriously.) These batteries have a limited lifetime and they need to be charged up if they haven't been used in a while. From the APC Forums an APC representative posted the following. Note #3: [QUOTE] Most APC batteries should last three to five years. Below are some guidelines to ensure optimum life expectancy: ***Some APC Back UPS models may have a shorter battery life expectancy. Please reference the user's manual of your APC Back UPS to determine the exact battery life expectancy. 1. Make sure that you keep your APC UPS in a cool, dry location with plenty of ventilation. Ideally, the temperature where your UPS is kept should not exceed 75° F (24° C). Also, for ventilation purposes, leave roughly one to two inches on each side for proper airflow. 2. Only perform runtime calibrations on your UPS one or two times a year, if necessary. Some of our customers want to check their systems to verify that their runtime is sufficient. However, consistently performing these calibrations can significantly decrease the life expectancy of your APC battery. 3. Do not store APC batteries for extended periods of time. New batteries can be stored for 6 to 12 months. After this period, the battery should be used or it will lose a great deal of its charge. It is not advisable to store batteries that have already been in use. 4. Do not exceed 80 percent of a UPS unit’s rated capacity due to the reduction in run time. When you increase your load, your runtime lessens. In the event of a power failure, a UPS loaded to full capacity will drain and discharge it’s battery quickly and will lessen the life expectancy.

[gentoo-user] Question about making a tarball
I try to keep a up to date stage 4 tarball here in my system just in case. I basically did the creation just like I would if I were booted from the CD. I created /mnt/gentoo/ on my system, extracted a stage 3 there, then chroot in and create a stage 4 tarball. I have one weird thing tho that has me confused. When it creates the stage 4 tarball, it is in /mnt/gentoo. Today I unpacked the stage 4 so that I could update it and when I do a tar xjpf stage4 -C /mnt/gentoo, it actually looks like this, /mnt/gentoo/mnt/gentoo/ which is not what I am looking for. It doesn't matter on a running system, but it would if I were trying to rescue myself. How do I tell tar when I am making the tarball to look at /mnt/gentoo/ as it start point, root directory if you will? I read the man page but suspect I am missing it somewhere. There has to be a way since it is done that way for the stage 3 tarball. Thanks Dale :-) :-)

Nikos Chantziaras wrote: 1) Better use -cjvpf (f) takes an argument (the filename of that tar to be crated) so it must be at the end. That's why I usually use tar -cjvp -f blabla.tar.bz2. I always seperate options that take an argument from the rest. But -cjvpf works too as long as f is at the end. This means that if you combine many options after a single -, only one one of them is allowed to take an argument; the last one. It might also be easier for you to use long options instead of short ones (easier to read). This: -cjvpf -C Is equivalent to: --create --bzip2 --verbose --preserve-permissions --file --directory So the original example becomes: tar --create --bzip2 --verbose --preserve-permissions --file /data/Gentoo-stuff/stage4-x86-04-2009.tar.bz2 --directory /mnt/gentoo .

The relevant lines from my apcupsd.conf are Yep, that's what I got. UPSCABLE usb UPSTYPE usb DEVICE blank didn't work in v3.14 for me. Now, with v3.12, this might change. I'll give it a whirl.

I basically did the creation just like I would if I were booted from the CD. I created /mnt/gentoo/ on my system, extracted a stage 3 there, then chroot in and create a stage 4 tarball. I have one weird thing tho that has me confused. When it creates the stage 4 tarball, it is in /mnt/gentoo. Today I unpacked the stage 4 so that I could update it and when I do a tar xjpf stage4 -C /mnt/gentoo, it actually looks like this, /mnt/gentoo/mnt/gentoo/ which is not what I am looking for. It doesn't matter on a running system, but it would if I were trying to rescue myself. How do I tell tar when I am making the tarball to look at /mnt/gentoo/ as it start point, root directory if you will? I read the man page but suspect I am missing it somewhere. There has to be a way since it is done that way for the stage 3 tarball. You strip the leading directory during extraction using the --strip=1 option (1 means strip 1 leading directory, which will ignore gentoo/ during extraction.) OK. That makes sense, sort of. How do the people that make the stage3 tarball do it? When I extract a stage3 tarball, it doesn't have /mnt/gentoo on it at all. Are they using a dedicated install to build those tarballs on? Also, since I want it to ignore /mnt/gentoo, wouldn't I have to use --strip=2 to remove both /mnt and the /gentoo after that? Just trying to make sure I understand this correctly. I would like to do this on the creating part if possible. To do this on creation, you can do use -C /mnt/gentoo . as options (translate: package the current directory of /mnt/gentoo). The top-level directory of the tarball will then be ./. I tried this but it didn't like it very much: r...@smoker / # tar -cjfvp /data/Gentoo-stuff/stage4-x86-04-2009.bz2 -C /mnt/gentoo/ tar: Removing leading `/' from member names tar: /data/Gentoo-stuff/stage4-x86-04-2009.bz2: Cannot stat: No such file or directory tar: Error exit delayed from previous errors r...@smoker / # I also tried reversing the thing, thought maybe I had it backwards, but it didn't like that either. Maybe I'm getting to old for learning new tricks. LOL Where am I wrong here? 1) Better use -cjvpf (f) takes an argument (the filename of that tar to be crated) so it must be at the end. 2) You are forgetting the dot (= current directory) at the end of the command: tar -cjpf /data/Gentoo-stuff/stage4-x86-04-2009.tar.bz2 -C /mnt/gentoo . Now that worked. Where are we told about that dot? I still don't see it on the man page. It has examples in there but no dot on the end. Cool stuff. Dale :-) :-)
