General :: Sync Two Directories Using Rsync?
Dec 24, 2010
I try to sync two directories using rsync.
the source is on Linux, and the other is on windows.
So, I mount the directory on windows using the command mount -t cifs . in Linux system.
Then I execute rsync ....
Everything is OK, but rsync prints out
rsync: chown "/mnt/windows/A/." failed: Permission denied (13)
rsync: chown "/mnt/windows/A/readme.txt" failed: Permission denied (13)
I want to sync the directories without changing ownership.

I wanted to create a consistent sync between two directories on two separate hosts. So when I write a file on one host, the file is automatically written on the next host. I don't have shared storage between each host.

Is there a way for me to rsync two directories comparing only filenames (and not file size, date modified, or any other criteria)?

I want to use rsync to synchronize some folders on my LAN. I have this working with two scripts; one runs at the beginning of my work session and gets the latest directory tree from the server, and the other runs at the end of the session to put any local changes back on the server. My "get" script looks something like this:
Code:
rsync -avuzb --backup-dir=/home/user/rsync_backup_dir --delete my_server:/home/bak/common_data/ /home/user/data
This works well, and with the "b" option any file that has been deleted from the master directory tree on the server will be deleted from the local machine and moved to the local backup directory. This is a safety measure to prevent the loss of files through a mistake (on my part).
The problem is the "put" script:
Code:
rsync -avuzb --backup-dir=/home/user/rsync_backup_dir --delete /home/user/data/ my_server:/home/bak/common_data
I want to run both scripts from the local machine, but the "put" script will not save deleted files to a backup directory. I tried using a remote backup directory like "my_server:/home/user/rsync_backup_dir" but this did not work. Is there a way to backup files deleted from a remote server from an rsync script run locally?

OK, here is the test code I am using: rsync -acrv /home/randy/Documents /media/USB2/testbackup. What should I put in the code so that when I delete something in the Documents folder, it will also be deleted in the testbackup folder when I perform a sync.
How can I have it so the code will check if USB2 is available, if it is, do the sync, if not, do nothing.

wrote a script to sync my netbook music with my server music and everything was fine.but if for some reason lets say i run it accidently and i'm not connected to my network, i just wiped my netbook music .here's what i got so far:
Code:
Sudo mkdir /media/ServerMusic/
mount -t cifs -o user=Justin,password=****** //192.168.1.108/Public-3/Music/ /media/ServerMusic/[code]....
i need to have the --delete option in rsync (say i sync it and realize i hate some music, when i delete it from the server i don't want it still on the netbook.i want an if statement in here somehow, but i'm not sure how to do it.something like, the first command in the script should be a ping test, if ping doesn't work end the script, if ping does work continue or if the server music gets mounted to the created directory continue, if the mount failed, or even in the mounted folder is empty stop the script
what can i do here to ensure i can keep the --delete and not have to worry about losing my music if the mount fails?

I need a program to run on Ubuntu that must be easily set up to do a series of different cloning operations at specific times between the USB drives on a single Ubunu pc, depending on the day of the week." So on Monday folder B is forced to match folder A, Tuesday C forced to equal D ... and on Sunday a whole bunch of these clonings happen. This must all run unattended (at 2am) and be robust with no "what do you want to do next messages" or having the whole thing give up if there is a problem with one file. Though I do need a log of success or failure. Windows programs that do this stuff are FolderClone and GoodSync. I looked at Unison and Rsync and one or two others, but none appeared set up to do what I need, or to be excessively complex / general. I don't need something that can sync two copies, or over internet ....

I'm looking for a way to sync directories between two computers, in a "two-way" fashion. Basically, I have a laptop and I have a desktop, and I want to keep a particular directory synced between the two machines. The easiest thing would be to have some kind of networked filesystem, but obviously this won't work because the laptop may or may not be connected to the internet at any moment. At any time I might be editing files on the desktop or on the laptop, and when the laptop is connected to the internet, I'd like all files on both machines to be synced to their most recent versions.
I thought I could do this with rsync but now that I've looked into a bit more it seems like it works only for "one-way" syncing. In other words files are synced from a server to a client or vice versa, but not both at once. First of all, am I right about that? And second, is there a program that will do what I want to do? OK, I guess you could do it with some SVN kind of thing but that seems like overkill. I guess if there's nothing out there it shouldn't be too hard to write a script myself to do it.

I'm hoping somebody can find something here that I haven't. I'm trying to use rsync to backup home directories to a nas. First, I NFS mounted the nas and ran an rsync and everything worked out fine. the transfer completed after a few hours and everyting was transferred (lots of stuff!). I then decided that I don't want to leave the nas mounted all the time and I didn't want to automate mounting and unmounting of the nas as I didn't think I could produce a script that would work reliably enough. So I decided to start an rsync daemon on the nas and upgrade via that. I run the following command (results are included. the ^C is me killing it after it hangs).
Code:
ryan@server:/etc/backup$ sudo rsync -ax --stats --progress --delete /data root@192.168.0.98:backups1
root@192.168.0.98's password:
sending incremental file list
data/home/user/Documents/
data/home/user/Documents/The File.wmv
[Code]...

I try to use rsync for backing up some directories and I have to following problem: some files have permissions that prevent me from running rsync under my own user id. So I run it under root using the option "-a" which according to the man page should preserve the permissions, owner and group information:
However, when I run this under root, the directories created in the backup location get user root and group root while ordinary files keep the original user and group. What am I missing here? How can I get rsync to preserve the user and groups for all files, including directories?
Here is a command to illustrate my problem
Code:
sudo rsync -a /home/youruser /tmp
If you try that and terminate with Ctrl-C after a few seconds, there will be a directory /tmp/youruser where the directories contained within are owned by root group root.

I want to sync several directories between my laptop and desktop both at home and away from home. It seems like the tool to use for this is unison (I use rysnc for backups, but union seemed, better for this sort of thing - let me know if I'm wrong).
I found several posts that appear promising, however I was little confused about the details as I don't have much networking experience up to this point.
[URL]
1) Is a reverse ssh connection the way to go? If I only wanted to do this on my home network I could just use ssh right, however in order to get around the router outside my home network the reverse ssh is necessary?
2) How do I handle changing IP address of my laptop?

I've discovered Firefox Sync a while ago, and it's absolutely awesome. Now of course I'd like most of my software to work this way! So is there a way to get the same behavior with Thunderbird?

I'm trying to rsync files and directories from a RedHat linux host(v 4.5 & 4.7) to a Windows server 2003R2 Standard Edition with cygwin running. I'm executing the rsync command from the cygwin shell. The transfer involves rsync'ing approximately 1 TB of data from the linux server to the windows server. After about 280+GB of data transfer, the transfer just dies.
There seems to be no particular file or directory that the transfer stops at. I'm able to rsync GB's of data from other linux hosts to this cygwin server with no problem. Files and directories rsync fine.The network infrastructure is essentially the same regardless of the server being rsync'ed in that it is GB Ethernet running through Cisco GB switches. There appear to be no glitches or hiccups across the network path.
I've asked the folks at rsync.samba.org if they know of any problems or issues. Their response has been neutral in that if the version of rsync that cygwin has ported is within standards then there is no rsync reason this problem should happen.I've asked the cygwin support site if they know of any issues and they have yet to reply. So, my question is whether the version of rsync that is ported to cygwin is standard. If so, is there any reason cygwin & rsync keep failing like this?
I've asked the local rsync on linux guru's and they can't see any reason this should fail from a linux perspective. Apparently I am our company cygwin knowledge base by default.

I want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?

I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?

Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.Searching the net makes one believe that this command is just some sort of magic.People just put it in the line and it just works. Isn't that nice?
It says nothing about how to change the TIME the audio starts syncing. Like do I want it to start 5 seconds delayed? Or what about 5 seconds sooner?What if the audio gets more out of sync as the video goes on? Can I slip it a little at a time? What? No magic?No one mentions a file that already has badly synced audio.So what -async 1 really does is simply start the audio at the beginning of the file. LIKE AS IF THAT ISN'T STANDARD PROCEDURE?So what is the exact solution to syncing a messed up video? And why can't it just do the proper "timestamp" sync in the first place?No docs, no info and you are left out in the cold.

Thought I'd post it here because it's more server related than desktop... I have a script that does:
[Code]....
This is used to sync my local development snapshot with the live web server. There has to be a more compact way of doing this? Can I combine some of the rsyncs? Can I make the rsync set or keep the user and group affiliations? Can I exclude .* yet include .htaccess?

When I run rsync --recursive --times --perms --links --delete --exclude-from='Documents/exclude.txt' ./ /media/myusb/
where Documents/exclude.txt is
- /Downloads/
- /Desktop/books/
the files in those directories are still copied onto my USB.
And...
I used fetchmail to download all my gmail emails. When I run rsync -ar --exclude-from='/home/xtheunknown0/Documents/exclude.txt' ./ /media/myusb/ I get the first image at url.

I have a tiny shell script to rsync files between two servers and remove the source files.
This script works fine, when it has been initiated manually or even when the rsync command is executed on the command line.
But the same script doesn't work, when I try to automate it through crontab.
I am using 'abc' user to execute this rsync, instead of root, as root login to servers are restricted in all of our servers, by us.
As I mentioned earlier, manual execution works like charm!
When this rsync.sh is initiated through crontab, it runs the first command(chown abc.abc ...) perfectly without any issues. But the second line is not at all executed, and there is no log entry i can find at /mnt/xyz/folder/rsync.log.

I just tried to sync files from one server to another. After the sync process, I found the files are bigger than original ones.
I looked up the web and found someone mentions the rsync daemon. So I have to run the daemon on one server before I run the rsync?
The command I used is rsync --partial --progress -r source destination
