13:01 dotplus pdurbin: I haven't used it yet, which is why I was asking for opinions. But I've written cheap db backup scripts for just about every consulting client and employer I've ever had and I'd like something a bit more solid/standard.  it supports mysql (w/xtrabackup which is awesome) and pgsql. seems to have a code layout that appears at first glance to make sense to me and it's written in a language with which I'm familiar so hopefully I can ...
13:01 dotplus ... more easily patch it for my needs.
13:16 pdurbin dotplus: I see. When I was looking for something kinda standard I went with mysql::backup from puppet: https://github.com/pdurbin/greptilian-vagrant/blob/master/modules/server1/manifests/init.pp
13:18 dotplus $org is not a puppet environment, we use bcfg2 (at the moment)
13:18 dotplus and cfengine2 and some other stuff. yes, I'm pushing for change:) but a) I'm new b) this is .gov
13:22 pdurbin does bcfg2 have a standard way to do backups?
13:26 dotplus oh. ew. mysql::server::backup is just using mysqldump. Now I remember why I wasn't using it at my previous employer where I did have puppet. mysqldump is fine if you just have small databases. but if you have 100s GiB or more, (which we did) a restore would take far too long because a restore was reloading from SQL. innobackupex from percona's xtrabackup meant that restore was just copying the files (could be rsync diffs if you use one file ...
13:26 dotplus ... per table) and therefore took 2 orders of magnitude less time.
13:27 dotplus bcfg2 does not have any builtin that provides backup functionality except that it keeps a backup of any file that it changes
13:27 dotplus nothing like this
13:27 pdurbin ok
13:28 pdurbin dotplus: was healthcare.gov your fault?
13:29 dotplus and given that my deployment/testing strategy was "broken? want a test/dev/training server? let's build a new one and restore the data", I need to be able to recreate databases quickly.
13:29 dotplus heck, no.
13:29 pdurbin heh
13:29 pdurbin dotplus: well, I hope you find a good solution. please report back
13:30 dotplus I'm running infrastructure for the HPC team @ornl.gov
13:31 * pdurbin looks at Oak Ridge National Laboratory | ORNL - http://www.ornl.gov
13:31 pdurbin dotplus: do you guys use slurm?
13:32 dotplus moab (mainly? perhaps there is slurm too?) At least I think that is the piece at the equivalent level of slurm, I'm not an HPC person myself, so I'm only tangentially aware of such things.
13:35 dotplus we have the largest machine (in this country) and several smaller ones, but we have some folks who babysit the supercomputers and clusters themselves. I'm just running infra services to support them. not really that different from any other hetergeneous medium/large environment.
13:35 HumanSky joined #crimsonfu
13:36 dotplus I know one of the clusters guys chuckles (privately) when interviewees ask abuot slurm because he's had some bad experiences but I don't know the details
13:37 pdurbin crimsonfubot: lucky largest computer in the united states
13:37 crimsonfubot pdurbin: http://www.computerweekly.com/news/2240088267/Worlds-biggest-computer-built-for-US-nuclear-department
13:38 dotplus err, see the date on that?
13:38 pdurbin bad crimsonfubot. no donut
13:39 dotplus http://www.top500.org/
13:40 dotplus http://www.top500.org/system/177975 is a better link
13:41 dotplus but there are several other large machines/clusters here as well as Titan

13:46 dotplus hm, perhaps westmaas can give opinions about Holland Backup since it's a RS project?
13:58 pdurbin joined #crimsonfu
14:05 pdurbin dotplus: looks like you've dropped to #2 ;)
14:10 antoon_i joined #crimsonfu
14:12 dotplus reading++ :)
14:12 dotplus #1 on top500 is not .us, it's .cn
14:12 dotplus I said "in this country"
14:14 pdurbin :)
14:16 dotplus but it's all silliness anyway. the only comparison that really makes any kind of sense to me is "computing power" per unit of energy. Of course you can make something more computationally powerful if you throw more Power at it. More efficient use of the power is what's interesting. And I'm fairly sure that there are lots of flaws in using FLOPS as a measurement of "computing power". It's likely the best indicator we have, but still rather ...
14:16 dotplus ... flawed.
14:16 pdurbin yeah
14:27 westmaas dotplus: sorry, I know nothing about holland backup!
14:29 dotplus no problem, I know RS is huge. worth a shot though:)

15:16 pdurbin westmaas: aren't you, like, Dutch or something?
15:17 westmaas pdurbin: :(
15:17 westmaas way to call me out twice
