Hello List, unfortunatelly rsync is beeing REALLY slow and produces a high load when we try to sync lots of files (>250 000 small files). My experience is, that this is fatser if i do it folder by folder. Is there a rsync option which reduces the load and speeds up the rsync somehow? Thanks, Mario

Dear List, I just googled "superlifter" and found below link, but I can't get any source code. http://superlifter.sourceforge.net/ Any help or info on this is mostly appreciated. And sorry for the trouble, if it's NOT allowed to post here. THanks. -- Daniel

Dear List, Currently, I read this in clientserver.c, line 148. motd = lp_motd_file(); I have googled, but didn't the definition of char *lp_motd_file(void). Can anyone help to explain the following code segment. Many thanks. #line 147 ~ 160, in clientserver.c, version 3.0.5 > if (!am_client) { > motd = lp_motd_file(); > if (motd && *motd) { > FILE *f =

Dear List, I'm confused when we will run into "if (motd && *motd)"? As I have found that Globals is set 0 during initialization, and I didn't find anywhere else assign the value. If so, should we remove this section? Or there might be some where I missed? Please correct me, if I'm wrong. Thanks in advance. clientserver.c #line 147~160 > if (!am_client) {

Hi List, Does Rsync support time slot back schema? E.G. (same local folder and remote destination) 1) first backup at 2008-12-24 2) second backup at 2009-02-12 But something bad happens to 2209-02-12, I need to restore files to first backup. Is there any way to do so? Any help is mostly appreciated. Thanks. Daniel

Dear List, option "-v" can output information to console. But it seems no effect with "rsync --daemon". So, how can I output verbose information to console when running with command "rsync --daemon" I also tried log file. Seems didn't work. Or is there any other way to read those information, Thanks in advance. -- Daniel

Dear List, I'm using rsync to sync my data, see below command. And I met this error? I think it might be due to 2.6.9 and 3.0.5 compatible issue. So how to solve the problem? Thanks. rsync -vrtopg --progress --delete --password-file=rsync-password /path/on/pc root@192.168.0.202::destination building file list ... 151804 files to consider rsync: push_dir#1 "/" (in maps) failed:

Dear List, When I use "access" function to find out if the folder exist in rsync code. I found that it's will NOT act as normal function. I have tried 2 test: a) embedded in rsync function "int recv_files(int f_in, char *local_name)" and hard coded with following line. access("/home/admin/test",F_OK) Result: Failed with -1, just mean the test folder is NOT

Dear List, I checked the function "generate_files", which might be simply stand for generator, but didn't find where triggers the file transfer. As receiver will use "read_ndx_and_attrs" to read iflags to judge if it's need to be transfered? If I'm wrong, please correct me. Can anyone help to point it out? Thanks. -- Daniel Li

Dear list, I have met this error.

Dear List, I'm trying to take a closer look at rsync code, and found when we run daemon, it will take a lot of CPU (400Mhz). So I'm interested in Which part of rsync code on ver 3.0.5 consuming CPU a lot? Can anyone here help to lighten me up? So I can try to improve the performance or low the CPU usage. I suspect that there are a few factors, which might related with CPU usage:

Dear List, I set up a NetBackup destination on my server. And I backup test1 to NetBackup/test1, test2 to NetBackup/test2. Now I wanna know how many folders that have been backuped. It should be 2 folders, with the name of test1 and test2. But I don't know if there is any way to do so? Any advice and help is well appreciated. Thanks. -- Daniel Li

Dear List, Currently, I'm trying to implement a new feature to rsync. Delta back: Well, it simply just backups diff blocks, and the program is able to restore to any backup points. Current problem met for adding files! But I met a newbie problem here. I'm going to add six files, which are diff.h/diff.c del.h/del.c and merge.h/merge.c. I have modified Makefile.in. When I add an

Dear List, I'm trying to get diff/removed data and it's offset out. So I write a functions in receive_data. When I run backup, I found there is a weird behavior which I don't understand. i = recv_token(f_in, &data) will receive (i = -1, offset2 = 0) some where in the middle of the transfer procedure. That's to say, it's going to transfer the first data block from sender,
