sysutils/snapraid 15.0 FreeBSD

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.
