similar to: Rsync: Re: patch to enable faster mirroring of large filesyst ems

I, too, was disappointed with rsync's performance when no changes were required (23 minutes to verify that a system of about 3200 files was identical). I wrote a little client/server python app which does the verification, and then hands rsync the list of files to update. This reduced the optimal case compare time to under 30 seconds. Here's what it does, and forgive me if these sound

In my particular case, it is reasonable to assume that the size and timestamp will change when the file is updated. (We are looking at it as a patching mechanism.) Right now it's actually using update time only, I should modify it to check the file size as well. Is there a way you could query your database to tell you which extents have data that has been modified within a certain timeframe?

Not in any practical way that I know of. It's not normally a major hassle for us since rsync is used for a central backup that occurs on a large enough time scale that the timestamp does normally change

I just took a look at the 2.5.5 codebase to see how easy it would be to write a little driver script that downloads a big directory tree from an rsync daemon the chunky way (get a list of a module's subdirectories and do the transfer by subdirectory). The reason for doing this is obvious when you have large directory trees, as is the case for many of us. Unfortunately the way list_only is

Is there a good place to get information about the list of all possible output and error messages rsync generates? Or should I just muck around the source code (which I haven't looked at yet) and find them? I am doing something where I would like to parse rsync's output using Perl into a set of data structures. I already have something that works under normal conditions. Eventually

Hi, I am thinking about a non-standard usage of rsync (at least not mentioned in the man file) I want to synchronized my collegues home directories(trees) each night AND store rsync's internal updating commands (reversed) to be able to restore the state of a directory the day before. This would require - saving the internal updating commands in a separate directory - reversing these commands

Rsync list: Alberto and I have done a couple more exchanges by private email, and we found that he wasn't turning on my include/exclude optimization in his test because he had an "exclude" directive in rsyncd.conf. He has now removed that and run the test again. His very interesting results are below with my comments. Note that his case is rather pathological because he's got

Dear all, I've been trying to track down a problem with timeouts when pulling data from an rsync daemon and I have now run out of any useful ideas. The problem manifests itself when I try to transfer a large directory tree on a slow client machine. What happens then is that the client rsync process successfully receives the list of files from the server, then begins checking the local

I saw several threads requesting an Asterisk forum to complement the email list. i.e. http://lists.digium.com/pipermail/asterisk-dev/2004-February/003103.html I recently created an Asterisk forum within TMC's popular VoIP forums for everyone to use. http://voip-forum.tmcnet.com/voip-forum/forum/forum_topics.asp?FID=15

At the moment, if you start an rsyncd that's not running as root using default settings it will have some trouble. rsyncd tries to use chroot by default, but this will always fail if it's not started by root. It does emit an error message in this case, but I wonder if some people find this a bit confusing until they discover the setting. I have in the past. It might be better that if

Hi Everybody, I'm new to this list, but I have been using rsync for quite some time. First, congratulations to the rsync team for a very fine piece of software! I'm wondering whether rsync could help me to perform the following task: I have 5 million files on one side of the ocean, 100000 of which must be copied to the other side. Both numbers grow with time, and occasionally, some

What is the best way to benchmark disk IO? I'm looking to move one of my servers, which is rather IO intense. But not without first benchmarking the current and new disk array, To make sure this isn't a full waste of time. thanks

Im setting up a very basic rails app and have a question about the needed migrations & associations. Basically, my app is an occasion reminder service that emails users when occasions that they select or input are coming up. Occasions will be selected from a checkbox type list or alternatively manually input by the user (name and date of the occasion). Users can have_many occassions.

I've got a problem w/ zap calls being dropped right after they are answered. I have a log file: http://pastebin.com/368526 Everything looks OK except for the DEBUG[25563] chan_zap.c: Exception on 9, channel 1 that seems to come up quite often. As soon as the other end of the Zap answers (my cell phone), and I can even hear a half second of noise, the line goes dead and gets hungup. In

I've got an issue w/ 1.2.0beta1, where if I call VoiceMailMain from a sip phone, and then either put in incorrect passwords or just hang up, I never get a Spawn Extension that hangs up the call, and my sip phone is not capable of making any more calls until I restart the daemon. Can anybody help me fix this? -- Jesse Keating GameHouse -- Systems Engineer

When I hang up in voicemail, Asterisk seems to stop responding. (hangup vs pressing # to disconnect). After that, no calls can be made until I restart Asterisk. In IRC, a developer seemed to think it had to do with me using switch => in my dial plan. Basically I never see the calling extension get the -1 signal. Can somebody help me figure out why this is happening and how I can fix it

hi evrey one, i'm in some kind interesting in developping some asterisk programme like doing a small programme including some of these services that do a telephone operator. but abviously i need to know about programming in asterisk in thos to files i think :) (extensions.conf and in sip.conf files) so i'm asking if someone can give me a puch,i will be very glad thanks in advance
