The file once, even after a copy operation to determine whether the file With the ability to detect, you can easily find out whetherĪ copy or extract operation occurred perfectly, or whether there has beenīackups provide point of reference, but comparison isn't very efficient,Īs it involves reading two files. This program was created to add an ability to detect (but notįix) issues. While BTRFS and ZFS can handle this, other filesystemsĬan't. While rare, the largeĪmounts of data being handled by drives make silent corruption a real Very small possibility of silent data corruption. Moving data from disk to disk, or leaving data on the disk, leaves a

Any data corruption ofįile changes would result in a failed check. Used to verify the checksum against the data. It simply calculates aĬhecksum and stores the checksum with the file. This program does not duplicate this ability, but offers rudimentaryĬhecksum abilities for other filesystems. With mirroring of data, they can silently heal the data should an error These filesystems ensure data integrity by storingĪ checksum (CRC) of data and checking read data against the checksum. This was inspired by the check-summing that is performed by filesystems By storingĪ checksum as an extended attribute, checkit provides an easy way toĭetect any silent data corruption, bit rot or otherwise modified error. Undetected data integrity issues or file changes to any file. Checkit allows you to detect any otherwise WHAT THIS PROGRAM DOES:Ĭhecksum adds additions data assurance capabilities to filesystems which
