Your disk just died,
but you manage to rescue your files!
Great! ... maybe?
Some data may have been corrupted, but you'll never know until you open and check each file.
chkbit can help you with that!
chkbit creates hashes (checksums) of your data on your primary disks. Then these index files (or just one file if you prefer) travel with your data onto your backups. You can verify at any time if your files are still good or if any data has been corrupted.
Data corruption can occur due to various factors, including software bugs, crashes, hardware errors (such as controller issues, failing connections, bad cables, and errors on the storage media), bit flips, power failures, environmental factors, malware, or even intentional actions by cloud providers that re-encode your media to save storage space.
