Dear Jean-Pierre, We created a test environment with Windows 2016 with data deduplication on.
I upgraded the backup server to install ntfs-3g 2016.2.22AR.1. I tried to mount the volume to see if I could read the files, but they show up as unsupported reparse point. I listed the Dedup/ChunkStore in the following pastebin: http://paste.debian.net/hidden/ca51ee46/ I tried to use the ntfs-plugin-80000013.so but I am not sure if it is being used, the bellow is not working so far? http://www.tuxera.com/community/ntfs-3g-advanced/junction-points-and-symbolic-links/ root@backup:~# ldd /bin/ntfs-3g linux-vdso.so.1 (0x00007ffd37ed0000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f2c3f203000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f2c3efe6000) libntfs-3g.so.871 => /lib/x86_64-linux-gnu/libntfs-3g.so.871 (0x00007f2c3ed94000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f2c3e9f6000) /lib64/ld-linux-x86-64.so.2 (0x00007f2c3f62b000) wget http://jp-andre.pagesperso-orange.fr/dedup.zip unzip dedup.zip cp --verbose dedup/linux-64/ntfs-plugin-80000013.so /usr/local/lib/ chmod 555 /usr/local/lib/ntfs-plugin-80000013.so chown root:root /usr/local/lib/ntfs-plugin-80000013.so root@backup:~# cat /etc/ld.so.conf.d/libc.conf # libc default configuration /usr/local/lib root@backup:~# cat /etc/ld.so.conf.d/x86_64-linux-gnu.conf # Multiarch support /lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu root@backup:~# chmod 555 /usr/local/lib/ntfs-plugin-80000013.so root@backup:~# ls -hal /usr/local/lib/ntfs-plugin-80000013.so -r-xr-xr-x 1 root root 16K Jan 10 11:51 /usr/local/lib/ntfs-plugin-80000013.so root@backup:~# ldconfig root@backup:~# ldd /usr/local/lib/ntfs-plugin-80000013.so linux-vdso.so.1 (0x00007ffff20a9000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fec8f5d1000) /lib64/ld-linux-x86-64.so.2 (0x00007fec8fb73000) root@backup:~# guestmount --ro -a /dev/lvm1-vol/sr7-disk1 -a /dev/lvm1-vol/sr7-disk2 -m /dev/sdb2 /mnt/sr7-sdb2 root@backup:~# ls -hal /mnt/sr7-sdb2/ALGEMEEN/ | grep "unsupported reparse point" lrwxrwxrwx 1 root root 26 May 19 2008 080514.Index I Directory algemeen.xls -> unsupported reparse point lrwxrwxrwx 1 root root 26 Dec 17 2009 2009-12-17 Index mappenstructuur.txt -> unsupported reparse point lrwxrwxrwx 1 root root 26 May 2 2013 ber_folders -> unsupported reparse point Kind regards, Jelle de Jong On 30/08/16 17:02, Jean-Pierre André wrote: > Jelle de Jong wrote: >> Dear ntfs-3g developers, >> >> I am using libguestfs to make file-based back-ups of kvm quests. >> >> Some of the guests are Windows Servers with NTFS formatting. >> >> We want to enable data deduplication on the Windows 2012 file servers, >> however a few years ago this caused libguestfs to stop working. >> >> What is the current status of ntfs-3g and support for mounting and >> reading Windows data volumes with ntfs and data deduplication enabled? > > I have uploaded to > http://jp-andre.pagesperso-orange.fr/advanced-ntfs-3g.html > a beta-test version of an ntfs-3g plugin for reading > deduplicated files stored by Windows 2012.
