CentOS 5 Hardware :: Rsync - Changed Blocks Or Files?

Sep 9, 2011

how rsync will handle disk images. Will rsync copy only the changed blocks of a vhd or a lun? This is what I've been told, but wouldn't this require overlaying a filesystem on the vhd? How would rsync handle copying a 500GB lun?

Ubuntu Servers :: Rsync - Backup Only Changed Blocks?

Aug 10, 2010

I'm going to make a nightly backup copy from one server to another, using rsync. If I have a sufficiently large file, say 4+ GB or so, I'm not interested in copying the whole file if only a small change has been made. Can rsync detect small changes on block level and backup only those if needed?

CentOS 5 :: RSYNC: Listing Files Added & Changed?

Oct 21, 2010

I'm using rsync to create a mirror of the data files on our main server every day. I've looked at the man page, and can't see it; can I get a listing of the files that have been changed on or added to the mirror when it's completed? Can it just log what it's doing to a file?

OpenSUSE :: Rsync Copying All Files Instead Of Just What's Changed

Jan 11, 2011

During my backups I'm finding that rsync is copying all files, instead of just what's changed.

I'm rsyncing between 2 USB external hard drives. One hard drive is FAT32 and one is NTFS. I've examined some of the files and believe that the difference is that there's a 1-second modtime difference developing in some of the files somehow.

Here's an example. These duplicity files were synced from /media/BACKUPHD (the NTFS drive) to /media/VIDEOHD (the FAT32 drive) only a few hours ago this morning. They have not been touched or changed since then, but that 1-second difference in their time stamps has appeared:

Code:
tim@localhost:~> stat /media/BACKUPHD/backups/duplicity/duplicity-full.20110107T145955Z.vol10.difftar.gpg File: `/media/BACKUPHD/backups/duplicity/duplicity-full.20110107T145955Z.vol10.difftar.gpg'

[Code]....

Programming :: Shell Script To Copy Newly Changed Files With Rsync?

Apr 20, 2010

I've got quite a decent rsync script setup, however I'd like to invoke it whenever there's change to a file. My initial idea was to use find, however this has two major flaws - the first being my particular unix veriant cant understand -print0 which means this doesn't work, the second is that I'm not 100% sure how to put variables into quotation marks so ls can understand the target:

Code:

for i in `find /shares/ -mtime -1 -print`; do ls -ltr $i;done

Software :: Run Rsync To Download Files From A Server Without Rsync Daemon?

Sep 18, 2009

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

Server :: Unifying Permissions Between Two Servers - CentOS - Webmin/CentOs - Cpanel - And Rsync

Jan 1, 2010

I have two servers, both running CentOS, but one running Cpanel as the control panel and the other running Webmin.

I would like to sync the web folders using rsync. However, when I sync the files from the Cpanel host the permissions look as follows:

Code:

But that doesn't work on the Webmin server which needs the following:

Code:

It seems the Cpanel install has the group as 'nobody' whilst webmin has it the same as the file owner. I can fix this by running:

Code:

But as the file transfers will be frequent, I don't want the files to be inaccessible until chown is run.

So, what I really want to know is - how can I change things on the 'webmin' server so that files with ownership owner:nobody will run?

General :: Changed Files Between Two Folders?

May 8, 2010

I have a directory (let's say A) with a few hundred files and subdirectories and a copy of this directory (let's say B). All the files and subdirectories in B have a newer date than A. However only a few of them are really changed files. Is there a way to find those files and directories? Basically they have different sizes so this could be used to compare them with the files from A.

General :: Backup Only The Files Which Have Changed?

May 18, 2011

if there an application which does the following:

1. I have a laptop with an internal 200GB HD.

2. I run the application & it creates a list of all files (size & time-stamp) without actually storing them. Let's call this the "snapshot list".

3. I update some of the files on the laptop.

4. Now I run the application & it only copies the files which have changed on the laptop, that have different size/time-stamp from the snapshot list, onto some external media, such as a memory card. Of course, the files should be copied onto their proper location in the directory tree & not just pile up in one place.

Why is this useful? although the laptop has a 200GB HD I typically only update a small number of files, whose total size is maybe 10MB or so. If I could only backup those which have changed, I could do this with a tiny SD card instead of lugging around an external usb HD.

Fedora :: Rsync Not Copying All Files?

Sep 9, 2011

My Source folder contains 424.8 GB in 502,474 files. My Destination folder was created fresh, and after the copy contains 394.0 GB in 486.514 files. I am running it as grsync with root authority. The only options are to preserve time, permissions, owner and group., and to produce a verose output and transfer progress. There are no exceptions specified to skip any files.

The rsync command is this:

rsync -r -t -p -o -g -v --progress -c -l -H -D -s /mnt/Backups/monthly.3/ /mnt/EX-Fantom/monthly.3/

I have run it again to give it a chance to get it right. Same result. The source is in an rsnapshot folder, but this is the first backup, the original, containing only whole files, not links.

General :: Rsync Would Keep Sending The Files Over And Over Again?

Mar 2, 2010

I'm trying to using rsync to backup some files, about half a TB. It's now it a state where it keeps sending the same files everytime it runs. for example:

rsync -av /data/source/* user@host:/data/dest
sending incremental file list
source/file1.txt
source/file2.txt

I then verify those files are copied over. then the next time it runs it does the same thing

rsync -av /data/source/* user@host:/data/dest
sending incremental file list
source/file1.txt
source/file2.txt

any idea why it's getting stuck on these files? I've tried to wipe the whole dest directory out and start over but no luck.

Ubuntu :: Rsync Wants To Recopy All My Files On Next Run / Why Is So?

Mar 15, 2010

So I just used rsync to backup about 400gb of data to my NAS. Look just over a day to complete, which is what I figured. I decided I should run rsync again to see how its going to handle comparing and only adding new files to the remote location. So I added a few new files and then ran the backup again. Well rsync is trying to do a complete copy of all of my original data, even though they have not changed.

Is there a way that I can tell rsync to compare the two directories and only add the new files and delete the ones that are no longer in the original location?

Here is command that I am running:

Code:
sudo rsync -azvv --progress --stats /media/sda1/multimedia/movies /home/codeblue/NAS_Share_Point

Ubuntu :: 5,149,552 Files In 30.2 GB And RSYNC Out Of Space?

Jun 9, 2011

I am running Ubuntu 10.04. I am transferring roughly 62 GB of data libraries to my 84 GB /home partition. I'm using rsync because scp kept stalling, and I had to restart it over and over. Things were going great until recently when it began to show an error: "failed: No space left on device (28)" These are the things I've done so far: Used the GUI to find out how much I have copied so far: 5,149,552 which take up 30.2 GB. df -h, it tells me that my /home partition is 56% used, and that I have 33 GB available. (42 GB used out of 78 GB with 33 GB available) Also, none of my other partitions are anywhere near 100%. the /home partition is the most-used and it's only a little over half-full. du -s in the directory where I'm copying all of this: it also returned 42206500. Additionally, when I try to save screen captures, it sometimes fails with a "device full" error. What's going on? Am I really out of space? Why doesn't it show me that I'm out of space?

Is there a hidden temp file that rsync uses that just got too full? I did a little research on wikipedia and it said that ext4 has a 64,000 directory limit. Could it be that I somehow broke that limit with all of these files? Solution: not enough inodes for the vast amount of subdirectories on hard drive. This wasn't an RSYNC problem, rather, a partition configuration issue. To check inode usage: df -i If you want to add any inodes, you will need to backup your partition and format it using mke2fs (man mke2fs). Be sure to change the respective inode setting.

General :: Rsync With Scp - Copies Everything - All Files

Jul 12, 2011

rsync -r -v -e ssh root@nn.nn.nn.nn:/usr/local/websites/* /usr/local/websites and each time I run it it copies everything - all files. I thought rsync was only supposed to copy files that had been added or modified.

Server :: Rsync Files Between Web Servers?

May 20, 2010

I've 15 web servers (in private network) running RHEL, Apache. Needs to sync web files between them. each server is accessible to each other via public key (with passphares).

1) Main server is web1 (where dev upload files initially). So I can make all other servers accessible by web1 without password/passphares and run rsync periodically to update files between them. But security is an issue here as all servers will become easily accessible.

2) Run rsync daemon in all other servers (except web1) on designated port and run rsync command from web1 to sync files. This will do the work but running daemon in all servers might increase overhead and making sure that daemon is running all the time etc. are my concern for this implementation.

CentOS 5 :: Rsync 3.0.7-1.el5.rf Does Not Work

Aug 18, 2010

I installed CentOS 5.4 on a virtual server to host the tool OpenVAS, which is used to execute vulnerability assessment.This tool is based on a master engine and thousand of plugins, each one doing a specific, little function.I wrote a cron that, every sunday, updates the list of these plugins to keep the system updated; this cron uses a tool's proprietary function that download the new plugins from a site using rsync.I was using the rsync 2.6.8-3.1 until last week, when I decided to install ALL the updates proposed by operating system itself (more than 170) and the whole list includes rsync 3.0.7-1.el5.rf (from rpmforge).

This monday, the log of the tool's function gave me a bad response about the impossibility to establish a connection with the remote server due to a connection timeout.Before doing the rollback of the system, I tried to understand what happened, so I started manually the function on a terminal and, together, I was watching the results using netstat -tuvnap, so I saw that there was an attempt of connection, between my server and the remote one, but the connection did not finish the three way handshake, because the state of connection was always "SYN_STAT".I tried to value the $RSYNC_PROXY variable, because there is a proxy between my server and the world, but the result was exactly the same, so I was forced to execute the rollback of the system, which works very well now!

CentOS 5 :: Yum Install FPC - Repositories Never Changed?

Dec 5, 2009

I've just tried to install freepascal [URL] on CentOS 5 using 'yum install fpc', and it installed package fpc-2.2.2-3.el5.1.i386. Since official stable version of freepascal is 2.2.4 (and version 2.4 will soon be released as new stable version), is it possible to update "official" freepascal in CentOS 5 repository to 2.2.4 (and later possibly to 2.4) ? I've read somewhere (wiki or website or some other place), that CentOS wont have php 5.2.5 because official CentOS repositories are never changed. Does this also apply to other software (like freepascal)?

Ubuntu :: Rsync Really Slow On Large Files?

Mar 1, 2010

I have Ubuntu on both my laptop and desktop machines, both are connected to the same network. I back up the laptop to the desktop by running the following on the laptop:

rsync -avv --stats /home/alisdt alisdt@xxx.xxx.xxx.xxx:/home/alisdt/laptop_backup (with the IP address of the desktop instead of the many x, obviously). Whenever rsync hits a large file (greater than a few MB), the network use rapidly drops to ~60KB/s (that's kilobytes not bits). When I copy the same file to the same place using scp, I get > 500KB/s throughout the transfer. Things I've tried:

* mounting the desktop home dir on the laptop using SSHFS -- a simple file copy is fast, rsync is still slow
* ditto with NFS
* rsync --whole-file option, in case the delta-transfer algorithm was choking on large files
* rsync --inplace option
* HPN-SSH (http://www.psc.edu/networking/projects/hpn-ssh/) to enable dynamic window and unencrypted bulk transfer, just in case it was some ssh bottleneck I think it's either an rsync application problem, or a network problem that is only affecting rsync. Any ideas, or other ideas of what I can try to debug? In case it's relevant, I'm using 9.04 on both machines. (A standing bug prevents me from upgrading the laptop, and I haven't bothered to upgrade the desktop).
