<0> I'd suggest looking at backuppc if you have a server somewhere
<0> hardlinked, exponential interval backups.
<1> CannedBar: these backups will be stored on an external hd
<0> via rsync, samba, etc.
<0> tro: ah.
<0> I would still suggest doing hardlinked rsync backups (unless you emerge -e world often)
<1> i have no experience with this: are incremental backups actually useful if i need to backup all /home and all config files, or will it get cumbersome to restore from 12456254 small backups?
<2> yes its more cumbersome
<3> tro you mix incremental with full ... like full on the weekends then incremental every weekday
<2> depends how big your entire data set is, and how much changes per day
<2> and how much effort it is to backup and restore
<1> logic_box: i'm gonna do a complete backup every month so i can restore easily
<2> many factors
<1> but then i need partial backups too
<1> just for config files
<2> what are you going to backup to?
<1> basically, i can reinstall gentoo on this machine fast and it's not critical or anything
<3> tro: the more offten you do a full backup the easier using the incrementals is
<1> foxdonut: external hd
<2> tro: why not just rsync?
<2> you can do fake snapshots with rsync, too
<2> so you maintain a history of changes
<1> foxdonut: i guess in case of some mild fs corruption that i don't notice until 50% of my backups are affected
<2> so you can restore a file from 3 weeks ago that you overwrote 3 times yesterday
<4> tro: a little. it'll only do one partition at once and I think you'll have to create the partitions first. I believe it has enough command line options to be scriptable though.
<1> that sounds good. there won't be too many changes. i gotta back up the configuration of all servers and everything in /home at least
<1> tomaw: i'll check it, but i like using tar for things :p
<1> at least i know i can always use
<4> fair enough :)
<1> it
<4> yeah
<5> t minus 69 minutes
<5> then i can go home, and fire up a fresh pot... of coffee.
<1> foxdonut: how would i do fake snapshots with versioning in rsync?
<5> got some old cold *** coffee here
<5> it's not
<5> i need fresh!
<2> tro: i'll dcc you the scripts i use if you want
<1> i kinda need restoring to be simple, because i may not be the one doing it. i may even have to dictate commands over the phone :(
<2> tro: rsync fakes it using hard-links
<5> foxdonut, i would like to see them.
<2> it works the same as real filesystem snapshots, like UFS2/veritas ****
<5> i have a set of my own, but would like to compare.
<1> foxdonut: dcc prolly won't work. behind a firewall
<2> i'll put it on http then :o
<2> sec
<1> awesome. good old http :)
<5> tro, the zv6000 article on gentoo-wiki has an incorrect cpu type
<5> shows a cpu that doesn't come in the laptop.
<1> o noes
<5> i'd edit it, but seems like everytime i do some ****er changes it back.
<1> url, pls

<1> i'm a trigger-happy banner
<1> wait
<1> admin, w/e
<1> i'm not a banner
<1> i just like to ban people
<5> did you ban that mfer anmaster?
<1> haha. no. he's got the most edits
<5> <1> no, he's the top contributor!
<1> can't ban him
<5> haha
<1> he just kinda went away
<1> burnt out, i think
<5> i think he was the one editing my changed!
<5> changes!
<1> #gw-rc is so much quieter now :p
<5> i quit contributing altogether because of that ****.
<1> he hasn't changed anything in a while
<5> not that i was a huge contributor.
<1> so log in, do you changes
<2> tro, katepls: http://www.haxor.me.uk/matja/bs/
<1> then if he starts an edit war, we'll discuss it on the ml
<1> foxdonut: thanks :D
<2> i've omitted the config directory i use
<2> because it has all the user/p***words ;)
<1> hhe
<2> basically i have a config directory, and every machine i want to backup is a directory in there
<2> and inside each machine directory is a service directory (cifs, mysql, rsync-ssh) with the options for that service (root, user, p***, etc)
<2> and i crontab make-snapshot to run every day
<2> it uses very little disk because of the hard-linking
<2> equivalent to the sum of the unique files
<2> cp -al / rsync --link-dest are the magic bits
<1> which part does the versioning?
<2> the rsync itself
<2> it makes a directory every time you run it
<2> named from the date and time
<1> ah
<6> hi
<2> with the entire backup set, hard-linked from the last one
<2> unchanged files are linked, changed files are stored normally
<7> whats a good port scanner for linux?
<2> KuR-RupT: nmap
<7> foxdonut: thx
<8> KuR-RupT: you ****tard
<7> MrStabby: you homo***ual lol
<8> don't make me sodomize you
<8> bbl
<9> In grub will /dev/sda2 = (hd0,1) ?
<10> glen, yes
<10> as long as /dev/sda2 is a hard drive.
<10> or rather sda is a hard drive.
<10> grub distinguishes between hard drives and other block devices (I'm 90% sure anyways)
<10> Hmm, think the number of computer related irc chat rooms you are in is inversly proportional to your chances of getting laid?
<11> but remember, the faster you download, the bigger your penis is
<10> Hmmm, in that case I probably shouldn't have quit right before our T3 gets put in.
<10> I guess I'll have a week or so of m***ive manhood.
<12> T3 is old school
<10> yeah, well if I could afford an OC-192 I'd get that...but
<10> Actually, I probably wouldn't. Manhood that size would drain all the blood from my body.
<10> Full length dual layer dvd's at 1 per second....
<10> oh, wait. Would take 8 seconds each.
<9> I have an e-penis of 15Gbps, therefor I have a bigger e-penis then everyone in Africa put together.
<13> fatal error: updatedb: create_db(): chdir: No such file or directory
<13> anyone care to explain this?
<9> Maybe you're lacking a database to update.
<13> im just running updatedb
<13> there
<9> What is the full command you're running?
<13> updatedb
<13> i got it, i think it was picking up a directory i had deleted that i was in
<13> well, hopefully ive purged my system of vmware
<9> I'm tring to get a Gentoo server working over SSH, it's the kernel which is broken :(
<5> http://shop4.outpost.com/product/4714029
<5> i might buy one of those for a windows box to do my UPS, and USPS on.
<1> foxdonut: your scripts are great, but they're probably overshot for my needs. i think i'm gonna need to sift through them and extract the main commands that i need
<1> 'cause basically, i only need to keep x number of backups and rotate them accordingly
<1> is there any way to step through the script line by line
<2> tro: yeah, i had to make them handle different services like svn, mysql, perforce, etc
<1> that would be awesome 'cause then i wouldn't have to look up 10 different man pages
<2> you prolly just want the rsync bit
<2> hmm
<2> dunno
<2> the cp -al /rsync --link-dist is the main bit
<2> the rest is just getting the files in the right place
<1> hmm ... seeing as how this will be on a removable drive, i wonder if i can set up udev to automatically execute the backup script when the drive is plugged in
<1> so does this system give you a full-system backup that you can just restore quickly to get back to a fully-functional system?
<1> fully-functional machine, i mean
<2> tro: it backs up to a huge raid disk array, i have a network-bootable version of gentoo which i can use to restore from it
<1> ah, that's kinda cool
<2> so if a machine dies, i netboot a new one, partition disk, and untar it
<1> how do you network boot?
<2> i use pxelinux, included with syslinux package
<2> you just add a couple of options to your dhcp server
<2> oh you need a tftp server too
<2> to send the kernel, initrd, and pxe loader
<2> saves carrying cd's arround
<1> this may be a n00b question, but this allows you to boot a machine that's been halted, right?
<2> halted?
<1> shut down
