backup program for disk arrays

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, where you have a lot of big files that rarely change.

Beside the ability to recover from disk failures, the other features of SnapRAID are:

 * You can use disk already filled with files, without the need to
   reformat them. You will access them like now.
 * 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.
 * 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, only a single disk needs to spin, saving power and
   producing less noise.
