Hi All: We have been looking at implementing deduplication on a backup server. >From what I have been able to find the available documentation is pretty thin. I ended up trying to install LessFS on this CentOS 5.7 box but we have now encountered problems with fuse version. Has anyone out there been able to get LessFS running on CentOS 5.7 and can provide some pointers? If not LessFS can you suggest an alternate deduplication software? TIA Regards, Hugh -- Hugh E Cruickshank, Forward...

Hi, I'm currently running GlusterFS over XFS, and it works quite well. I'm wondering if it's possible to add data deduplication into the mix by: glusterfs --> lessfs --> xfs or glusterfs --> opendedupe --> xfs Has anybody tried doing this? We're running VM images on gluster, and I figure we could get a bit of space saving bu deduplicating the data. Gerald

Hi list, is there any working solution for deduplication of data for centos? We are trying to find a solution for our backup server which runs a bash script invoking xdelta(3). But having this functionality in fs is much more friendly... We have looked into lessfs, sdfs and ddar. Are these filesystems ready to use (on centos)? ddar is sthg different, I know. Thx Rainer

Hi all, Back in March someone asked about deduplication in Centos and I replied I'm using LessFS. I want to report that my overall experience is that I have performance issue up to the point that I would like to abandon it. The OP was asking http://www.opendedup.org/ How is it? Thanks Fajar

Hi, so here it is, LZ4 compression method inside btrfs. The patchset is based on top of current Chris'' for-linus + Andi''s snappy implementation + the fixes from Li Zefan. Passes xfstests and stresstests. I haven''t measured performance on wide range of hardware or workloads, rather wanted to publish the patches before I get distracted again. I''d like to ask

Here is a short proposal for the hybrid storage cache idea with introduction/motivation and a bird''s eye view of an approach to implement a hybrid storage cache for btrfs. Please note that there is currently no available patches. We would like to get as much input before as possible before we start designing and implementing a solution. 1.

I apologize if this has already been discussed before, but as of yet I have been unable to find any info on the topic. I have a very simple (and common) disk based backup system using rsync, hard links, and a little bit of perl to glue it together. Remote machines are backed up regularly using hardlinks across each snapshot to reduce disk usage. Recently I learned that rsync does a

Hallo, we have a clinical system that generate lot of files that once written are never changed. This file consume lot of disk and tape space*, so my idea was to compress this files. The problem is that it can happen, that the users have to open this files later. Is there a VFS module for samba that show gzipped** read only files as if they were standard files ?

I don't know the price - I've only been here a few weeks. I'll have to check when I'm back at work for details on it - don't have my VPN login yet.

Hello forum, I am a Teacher at a German school and I want to get rid of Windows. I successfully installed Ubuntu 10.04LTS and configured the system to run as needed. My Problem is the following: I have 900 Users. If all of them use wine to start a program, every user installs his own .wine directory with all the content. Soon I have gigabytes of redundant stuff. Also I need to install some

Hey folks, I have a 14TB disk array that I want to use for rsnapshot backups, and am considering putting a dedup FS onto it. I know I've got about a TB of duplication, at least. And it is not easy to remove manually. Google lands me LessFS and SDFS as the prime candidates. thanks, -Alan -- ?Don't eat anything you've ever seen advertised on TV? ? ? ? ?? - Michael Pollan, author of "In Defense of Food"

I have set up the configurations and profiles for some of my programs so that I can use them across distros, and easily configure new installations with all my old settings. For instance, if I use Firefox in Fedora, add some bookmarks, then go to suse or Mandriva the new bookmarks are there, as is history, etc. Same for Thunderbird. To do this I copy the relevant folder from /home/user to my

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the
