| 05:31 | <@Chalcedon> | can anyone suggest a method of imaging my hard drive? Copying the files is a long and frustrating process. |
| 05:39 | <@ToxicFrog> | dd? |
| 05:40 | <@ToxicFrog> | But unless the source and target drives are the same size you'll have to resize the filesystem. |
| 05:40 | <@ToxicFrog> | Personally, I'd just copy all the files with rsync. |
| 05:44 | <@Chalcedon> | rsync? |
| 05:45 | <@Mahal> | What're you needing to do, Chalcy? |
| 05:45 | | * Chalcedon displays her ignorance again |
| 05:45 | <@Chalcedon> | I need to back up my hard drive before reformatting it |
| 05:45 | | * Chalcedon realises she needs to pay a visit to hamilton to borrow her parents XP CD |
| 05:46 | <@Mahal> | Ah, I see. |
| 05:46 | <@Mahal> | Hrm |
| 05:47 | <@Chalcedon> | (note that I need an XP home CD, hence Hamilton and parents) |
| 05:47 | <@ToxicFrog> | Rsync is a program for synchronzing files between two computers, over ssh. It can also sync files between two paths on one computer. |
| 05:48 | <@ToxicFrog> | Some notable advantages are that it only transfers what it needs to, and it uses checksums to verify that everything copied correctly. |
| 05:48 | <@ToxicFrog> | The former meaning that if it gets interrupted, it picks up from where it left off when you run it again, and if you sync and then change something and resync, it only copies the changed files. |
| 05:49 | <@Chalcedon> | ah ha. |
| 05:49 | <@Chalcedon> | that sounds like exactly what I need. |
| 05:50 | <@Chalcedon> | the next question would be how do I get it to work in windows? |
| 05:50 | <@Chalcedon> | cygwin? |
| 05:50 | <@ToxicFrog> | If you have Cygwin, it comes with rsync. |
| 05:50 | <@ToxicFrog> | If not, I can send you rsync.exe and the cygwin DLLs it uses. |
| 05:50 | <@Mahal> | And it stillr equires somewhere else to put the files |
| 05:51 | <@Chalcedon> | Forjs HD |
| 05:51 | <@ToxicFrog> | Mahal: I'm assuming that she does in fact have a second drive to put them on. |
| 05:51 | <@Chalcedon> | does Cygwyn need to be installed on both ends? |
| 05:51 | <@ToxicFrog> | Umm. I thought the drives were both in the same machine at the moment? |
| 05:52 | <@Chalcedon> | no. Sorry, transfer via network |
| 05:52 | <@Chalcedon> | I take it this complicates things? |
| 05:52 | <@ToxicFrog> | If they're both in the same system (or look like they're both, eg, a windows or NFS network drive), you just need rsync. |
| 05:53 | <@ToxicFrog> | If you're doing it over SSH, the remote system needs to be running an sshd and have rsync installed. |
| 05:53 | <@Chalcedon> | I can map a network drive fine. |
| 05:53 | <@Chalcedon> | at least, I think that's what you're talking about |
| 05:54 | <@ToxicFrog> | Yes. |
| 05:54 | <@ToxicFrog> | Basically, if you can see both drives from one computer, all you need is rsync on that computer. |
| 05:55 | <@ToxicFrog> | You need it on both computers when you /can't/ do that and need to transfer over SSH instead. |
| 05:55 | | * Vornicus-Latens applies Stoat in Curry Sauce to Chalcy |
| 05:55 | <@ToxicFrog> | It will of course be slow, because it'll be copying them over SMB underneath, and SMB is ass-slow. |
| 05:55 | <@ToxicFrog> | But at least it won't re-copy anything, and it'll verify all the files. |
| 05:56 | | * Chalcedon nrom |
| 05:56 | <@Chalcedon> | which is a very handy feature |
| 05:57 | <@Chalcedon> | I'm happy to leave it copying overnight if necessary. I won't be going to Hamilton before Wednesday anyway |
| 05:57 | | * ToxicFrog nods |
| 05:57 | <@Chalcedon> | the only other thing, is how do I operate rsync? |
| 05:57 | <@Chalcedon> | I don't use Cygwin nearly as much as I ought, so I forget how to work it. |
| 06:02 | <@ToxicFrog> | rsync -avvh --progress /path/to/source /path/to/dst |
| 06:03 | <@ToxicFrog> | Be careful of / on the end of source; 'source' means 'copy the directory source and everything in it'; 'source/' means 'copy everything inside the directory but not the dir itself' |
| 06:03 | <@ToxicFrog> | And for the manual: 'man rsync' |
| 06:04 | <@Chalcedon> | this is in the bash shell, yes? |
| 06:05 | <@ToxicFrog> | Yes. |
| 06:05 | <@ToxicFrog> | I can give you the exact command if you'll tell which drives things are on and where you want it saved. |

| 06:06 | <@ToxicFrog> | Aah, Forj. |
| 06:06 | <@ToxicFrog> | Have a sizzling weasel on a stick. |
| 06:06 | < Forj> | mmm, sticky weasel :) |
| 06:07 | <@Chalcedon> | well I want to copy C:\ to I:\ |
| 06:08 | <@ToxicFrog> | In that case: rsync -avvh --progress /cygdrive/c/ /cygdrive/i/ |
| 06:09 | <@Chalcedon> | uh |
| 06:09 | <@Chalcedon> | how do I escape the manual? |
| 06:10 | <@Chalcedon> | I didn't realise it was that long |

| 06:10 | <@ToxicFrog> | Scrolling to the bottom won't exit it anyways. |
| 06:10 | <@ToxicFrog> | q is exit, > is bottom, < is top, pageup/pagedown and up/down move by screens and lines respectively, / is search down, ? is search up. |
| 06:11 | | * Chalcedon nods |
| 06:12 | <@Chalcedon> | I typed that and it gave me a whole speel on instructions and the program, then returned the $ (as in ready for new command) |
| 06:13 | <@Chalcedon> | I can't believe it copied that quickly, so is it working, or did I do something wrong? |
| 06:13 | <@ToxicFrog> | ...er. |
| 06:13 | <@ToxicFrog> | Oh. |
| 06:13 | <@ToxicFrog> | Try -avv instead of -avvh |
| 06:13 | | * ToxicFrog forgot that the Cygwin version is a bit behind the Linux one and doesn't support -h |
| 06:14 | <@Chalcedon> | ah |
| 06:14 | <@Chalcedon> | Windows tried to block it but I told it to go away |
| 06:14 | <@ToxicFrog> | It handles local copies, IIRC, by spawning a seperate copy of itself and then talking to itself over the network. |
| 06:14 | | * Chalcedon hugs TF and supplies white chocolate and raspberry muffins |
| 06:14 | <@ToxicFrog> | Thus allowing it to use the same code as if it were doing a networked copy. |
| 06:14 | <@Chalcedon> | hee |
| 06:15 | <@Raif> | ... |
| 06:15 | <@Raif> | That's actually kinda gross. |
| 06:15 | <@Chalcedon> | is it supposed to tell me that files have vanished? |
| 06:15 | <@Raif> | Cool, but gross. |
| 06:15 | | * Chalcedon eyes Raif |
| 06:15 | <@ToxicFrog> | Raif: no it isn't. It's a perfectly normal technique. |
| 06:16 | <@ToxicFrog> | Especially when you have to run on a system that doesn't have UNIX domain sockets. |
| 06:16 | <@ToxicFrog> | Chalcedon: vanished? |
| 06:16 | <@ToxicFrog> | Wha? |
| 06:16 | <@Chalcedon> | file has vanished: "/cygdrive/c/cygwin/proc" |
| 06:16 | <@Raif> | hehehe |
| 06:16 | <@Chalcedon> | most of them are wma's |
| 06:17 | <@Chalcedon> | (thus I'm not very worried) |
| 06:18 | <@ToxicFrog> | Oh gods. |
| 06:18 | <@ToxicFrog> | I almost forgot. |
| 06:19 | <@ToxicFrog> | Interrupt that with ctrl-c |
| 06:19 | <@Chalcedon> | ? |
| 06:19 | <@ToxicFrog> | The rsync. Interrupt it. |
| 06:19 | <@Chalcedon> | I did |
| 06:19 | <@Chalcedon> | the ? was for what did you forget? |
| 06:19 | <@ToxicFrog> | Exclusion listing. |
| 06:20 | <@Chalcedon> | ? |
| 06:20 | <@ToxicFrog> | In particular, /cygdrive/c/cygwin/cygdrive needs to be excluded from the copy. |
| 06:20 | <@Chalcedon> | otherwise it will die horribly? |
| 06:20 | <@ToxicFrog> | As otherwise it'll try to copy /cygdrive/c/cygwin/cygdrive/c |
| 06:20 | <@ToxicFrog> | And then /cygdrive/c/cygwin/cygdrive/c/cygwin/cygdrive/c |
| 06:20 | <@ToxicFrog> | You get the idea. |
| 06:20 | <@Chalcedon> | and that could become ....yes |
| 06:20 | <@Chalcedon> | so how do I exclude that? |
| 06:21 | <@ToxicFrog> | One moment, consulting the manual |
| 06:22 | | * Chalcedon hugs TF |
| 06:22 | <@ToxicFrog> | rsync -avv --progress --exclude=/cygdrive/c/cygwin/cygdrive /cygdrive/c/ /cygdrive/i/ |
| 06:23 | | * Chalcedon hugs TF |
| 06:23 | <@Chalcedon> | you're a life saver :) I'd probably spend hours trying to figure out how to do this myself and still get it wrong |
| 06:23 | <@ToxicFrog> | Aha. The "file has vanished" stuff is related to an issue with non-ASCII filenames on XP with recent Cygwin builds. |
| 06:24 | <@ToxicFrog> | Specifically, stuff with non-ASCII characters in the filename will show up in readdir() but stat() will fail, so it sees the file in the directory listing when it goes to actually copy it it gets nothing back. |
| 06:25 | <@Chalcedon> | thus the file vanishes |
| 06:25 | <@ToxicFrog> | Yeah. |
| 06:26 | <@ToxicFrog> | From rsync's point of view, the file has disappeared between looking at the directory and looking at the file itself. |
| 06:26 | <@Chalcedon> | those files have funny boxes in the file name, thus it's highly unlikely anything I'm worried about will get missed like this. |
| 06:26 | | * Chalcedon nods |
| 06:27 | <@ToxicFrog> | Yeah, those are non-ASCII characters that it's having trouble rendering. |
| 06:27 | | * Chalcedon nods |
| 06:27 | <@Chalcedon> | it's also not a problem, thankfully |
| 06:28 | <@ToxicFrog> | Alright then. |
| 06:28 | | * Chalcedon hugs TF |
