https://bugzilla.samba.org/show_bug.cgi?id=7854 Summary: Abysmal sparse file performance Product: rsync Version: 3.0.7 Platform: x86 OS/Version: FreeBSD Status: NEW Severity: major Priority: P3 Component: core AssignedTo: wayned at samba.org ReportedBy: grarpamp at gmail.com

I have a 5.5GB file, mostly sparse. Tar performs far[!] better than rsync. I have no ideas yet, so just an FYI as to current state. FreeBSD 8.1 i386 zfs Yes, I know the blocks used differs but don't know why yet, could be just how zfs does things or related to the large amount of sparseness. There are no media errors, CPU/IO load or anything like that and the source and dest paths are on the

How do you handle snapshotting? or do you leave that to the block/fs virtualization layer? /kc On Fri, Apr 17, 2015 at 01:35:27PM +1200, Henri Shustak said: >> Our backup procudures have provision for looking back at previous directories, but there is not much to be gained with recycled directories.

I am a developer on the LBackup project. An LBackup user recently posted a question to the mailing list asking about the following error. > "rsync: unpack_smb_acl: sys_acl_get_info(): Unknown error: 0 (0)" Link to thread : <http://www.mail-archive.com/lbackup-discussion at lists.connect.homeunix.com/msg00040.html> My understanding of this error is that when copying files via

As Ben mentioned, ZFS snapshots is one possible approach. Another approach is to have a faster storage system. I have seen considerable speed improvements with rsync on similar data sets by say upgrading the storage sub system. -------------------------------------------------------------------- This email is protected by LBackup, an open source backup solution http://www.lbackup.org

I am involved with the development of lbackup. This message to the rsync mailing list is related to the following thread on the lbackup-disccussion mailing list : http://tinyurl.com/lbackup-discussion-diskfull Essentially, I am curious to if any one using rsync 3.0.7 on Mac OS (10.6) Server has experienced an out of disk space error and not had a message similar to the following reported : >

I am wondering if there is an option which is similar to --progress that will not display the file names. A percentage indicator would be fine. There is some related discussion at the following URL : http://lists.samba.org/archive/rsync/2004-March/008998.html Any replies regarding ways to achieve this kind of output are welcomed. In addition, a reply like "sorry not supported yet"

Just chiming in slightly off topic. As a first step if you are going to be backing up files to some media with a computer it would be a really good idea to ensure, that the hardware being used is not faulty. I am not saying that your hardware is faulty. However, it would be worth checking this somehow. Check the drive media for bad blocks, check that all the cables are working well. Ensure the

> Our backup procudures have provision for looking back at previous directories, but there is not much to be gained with recycled directories. Without recycling, and after a failure, the latest available backup may not have much in it. Just wanted to point out that LBackup has a number of checks in place to detect failures during a backup. If this happens, then that backup is not labeled as a

I have a volume at 192.168.0.2 on my local network. I'd like to rsync the entire volume to a backup volume, skip all files already present on the backup volume (same name and the same or earlier timestamp), and include all flags, dates, etc. as applicable to Mac OS X 10.6.x. Can someone tell me the proper command to do this.

I think others have answered your questions. You may want to implement some sort of locking system in the script so that you can only run a single instance of your script at. If you are looking for a backup tool which leverages rsync you may want to take a look at LBackup : http://www.lbackup.org There is even a pre-script you can enable (in the example resources) so that the script can run a

Firstly, if this the wrong place to ask this question or if this question is inappropriate then please accept my sincere apologies. I am seeking advice regarding the backup of an Windows XP machine. I have used rsync for years and believe it to be an absolutely amazing tool on *NIX systems. Recently, I was asked the following question, relating to the backup of Windows system : >

Hi, I''m wondering if it''s a known problem but recently I had to revert a production server from 1.8.6_p287 to 1.8.6_p114 because the performance was abysmal. ./script/runner took nearly 40s to load the Rails environment before doing anything useful on a Core2Duo 2.66GHz running Gentoo Linux 64bit. ./script/console was affected too (~40s to prompt) and our most used controller

I'm using rsync 3.0.7 on Mac OS X 10.6, compiled according to Mike Bombich's instructions at http://www.bombich.com/rsync.html. Rsync repeatedly exits with a protocol data stream error when trying to copy some com.apple.FinderInfo extended attributes. While testing this issue, I found that rsync is not actually copying all extended attributes even when there is no error message. I'm
