    SnapRAID v7.0 has been released at :

    http://snapraid.sourceforge.net/
    

    SnapRAID is a backup program for a disk array.

    SnapRAID stores parity information in the disk array,
    and it allows recovering from up to six disk failures.

    This is the list of changes:

    • In 'check' and 'fix' the array is scanned to find any moved files
      that could be used to recover missing data. Files are identified by
      timestamp, and then they are recognized also if moved to a different
      disk. Note that even if there are false positive they are identified
      checking the hash, so they have not effect, besides making the
      process a little slower. To disable this new behavior you can use
      the -N, --force-nocopy option.
    • The -i, --import command now identifies files by timestamp making it
      very fast in importing directories.
    • More detailed 'status' report with single disk stats and free space
      available.
    • A lot faster directory listing for Windows.
    • Adds AVX2 support to improve parity generation speed.
    • Prints the time spent waiting for each disk also in 'scrub'.
    • The CPU usage, speed and ETA estimations are now based on the last 100
      seconds rather than from the start.
    • Keeps track of the UUID of the parity disks to check them before
      operating.
    • Windows binary built with gcc 4.8.1 using the MXE cross compiler 2.23.

      Thanks for all your work!

      This thing just keeps creeping around and taking over new tasks here. Wish "rest of our software" worked this well :)

    Great job Andrea! This just keeps getting more features while continuing to be easy to understand and being super stable.

    Agreed..

    My Debian 7 + SnapRAID + mhddfs setup is rock solid.

    Every now and then I'm tempted to go full on ZFS or Btrfs and then I remember the headaches and complexities that brings.

    Loving the solution Andrea.

    Good work!

    Yea, I have snapraid + mhddfs myself, everything working as it should (have the 7 beta, but I'll upgrade probably tonight).

    I've had a fully supported (I mean covered by support contract & all) Solaris 11 x86 zfs box with plenty of cores and tens of gigs of ram just as a backup fileserver and it was giving me ulcer. Transfer performance was abysmal but worse the hard drives where busy without basically any activity on the box.

    Back to linux land ext4 works as it should at "real" hdd speed, snapraid is quick and insures integrity. Can you ask for more?

    It would be nice if, when the ETA gets down to less than one minute, instead of the ETA disappearing completely, it should change to "ETA: <1 min" or something like that.

    Hi
    Silly question time, this is my first version change for SR, how do i go about upgrading on Ubuntu server?

      You upgrade the same way that you did the original install. SnapRAID will be replaced with the newer version.

      wget http://sourceforge.net/projects/snapraid/files/snapraid-7.0.tar.gz
      tar xzvf snapraid-7.0.tar.gz
      cd snapraid-7.0/
      ./configure
      make && make check
      # If everything goes well with the check...
      make install

        Many thanks rubylaser
        I thought it was just wanted to double check before i went ahead with the upgrade, last thing i wanted to do was mess things up :).

        Thanks again
