Deduplicate not processing all messages - bug?
Hello, I'm trying to create automated backup recovery using "doveadm import" and "doveadm deduplicate". During testing I noticed that deduplicate only deletes some duplicates and has to be called multiple times to find them all. Here's what I've been trying (in shell commands): First, expunge inbox (the end result is the same even if you delete only some

[RFC] - Deduplication of debug information in linkers (LLD).
?But could not we for example do split dwarf, but for example do dedup of types ? I do not mean right now, but in a theory ?

Deduplication data for CentOS?
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

Deduplication active - but how good does it perform?
I have deduplication active in my first mdbox: type mailbox, but how do I find out how well the deduplication works?

Deduplication and block size
Nothing too interesting here, I was just playing around with the idea of a deduplication allocator for nbdkit (“allocator=dedup”, see https://rwmj.wordpress.com/2020/06/15/compressed-ram-disks/). Before implementing such a thing I wanted to know if there's much duplicated structure in a disk image. It seems to depend very critically on the block size, but also there are no significant

deduplicate mode?
Have you considered to introduce a "deduplicate mode" for rsync, replacing duplicate files in the destination directory by hard links? Of course there might be a lot of problems together with this feature, but on creating backups it could help to save a lot of disk space. --link-dest might be interesting in this context, too.

Deduplication
Hello, some questions regarding btrfs deduplication. - What is the state of it? Is it "safe" to use? https://btrfs.wiki.kernel.org/index.php/Deduplication does not yield much information. - https://pypi.python.org/pypi/bedup says: "bedup looks for new and changed files, making sure that multiple copies of identical files share space on disk. It integrates deeply with btrfs so

doveadm sis deduplicate problem
Hi all, I'm running dovecot 2.3.7.1, with mdbox and single instance storage. I use offline deduplication like this: mail_attachment_fs = sis-queue /mailboxes/%d/_attachments_/queue:posix Each week I run doveadm sis deduplicate to deduplicate the mail attachments. Everything was fine until I mistakenly run doveadm sis deduplicate twice, simultaneously. I ended up having some error messages

Many questions from a potential btrfs user
Hi. I am seriously considering employing btrfs on my systems, particularly due to some space-saving features that it has (namely, deduplication and compression). In fact, I was (a few moments ago) trying to back up some of my systems to a 2TB HD that has an ext4 filesystem and, in the middle of the last one, I got the error message that the backup HD was full. Given that what I backup there are

CentOS and LessFS
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

Zfs deduplication
Will the material ever be posted. Looks there is some huge bugs with zfs deduplication that the organizers do not want to post it also there is no indication on sun website if there will be a deduplication feature. I think its best they concentrate on improving zfs performance and speed with compression enabled. -------------- next part -------------- An HTML attachment was scrubbed... URL:

GlusterFS over lessfs/opendedupe
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

[RFC] - Deduplication of debug information in linkers (LLD).
>Not quite sure what you mean by "on linker side" - but I guess you mean using linker features like comdats etc, rather than DWARF parsing/reassembly/etc. I mean that it probably not a good idea for external library. I feel it is much more convinent to do such proccessing in a linker. Linker do and knows much more about things like sections that are ICFed, eliminated, about COMDATs
