    Un peu étonné de pas voir Snapraid mentionné. Juste pour citer le site snapraid.it :

    SnapRAID is a backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures.
    SnapRAID is mainly targeted for a home media center, with a lot of big files that rarely change.

    Beside the ability to recover from disk failures, other features of SnapRAID are:
    All your data is hashed to ensure data integrity and to avoid silent corruption.
    If the failed disks are too many to allow a recovery, you lose the data only on the failed disks. All the data in the other disks is safe.
    If you accidentally delete some files in a disk, you can recover them.
    You can start with already filled disks.
    The disks can have different sizes.
    You can add disks at any time.
    It doesn't lock-in your data. You can stop using SnapRAID at any time without the need to reformat or move data.
    To access a file, a single disk needs to spin, saving power and producing less noise.

    Je tourne avec 3x3To, dont 2 disques sont alloués au stockage proprement dit et 1 disque alloué aux sommes de contrôle. Snapraid vérifie les sommes de contrôle et les fichiers correspondants régulièrement et petit à petit (8% à chaque fois), ce qui fait qu'on est alerté en cas de corruption silencieuse.
