pgBackRest aims to be a reliable, easy-to-use backup and restore solution that can seamlessly scale up to the largest databases and workloads by utilizing algorithms that are optimized for database-specific requirements. Compression is usually the bottleneck during backup operations but, even with now-ubiquitous multi-core servers, most database backup solutions are still single-process. pgBackRest solves the compression bottleneck with parallel processing. Utilizing multiple cores for...

Checkit is a file integrity tool that adds basic data assurance capabilities to file systems which support extended attributes. It allows you to detect any data integrity issues or file changes to any file. By storing a checksum as an extended attribute, checkit provides an efficient way to detect silent data corruption, bit rot, or other modification errors. It was inspired by the checksumming performed by filesystems like BTRFS and ZFS. Checkit allows similar functionality, the ability to compare stored files and entire directory trees against a checksum at a glance.

New versions @ https://github.com/hansij66/securecopy crccp and crcmv are based on coreutils (v8.23) and add crc checksum functionality to cp and mv commands. Checksums can optionally be stored in the file's xattr. The command crcsum can be used for further checksum analysis/verification, or for storing a checksum in the xattr of all files in a directory or filesystem.

hufc is a utility to compress or expand files using Huffman coding. It can use a 16-bit CRC or the IP checksum for error detection.

md5cp will traverse a file tree and check the MD5 checksum of each file. If the file is unchanged, it is ignored; if it is changed (or new), its MD5 is updated in the database, and the file is copied to the destination directory. A number of optional parameters can change what happens in addition to the file copy. This utility is useful for situations when file dates are corrupt and rsync cannot be used.
