OtheRSync is a program for the automatic, efficient, and safe synchronization of two machines over a network. It's efficient (using compression and incremental changes), safe (uses ssh, is fail-safe, and makes backups of deleted files by default), uses parallel processing, and supports feedback through the commandline prompt. It is built on top of rsync. New or changed files are synchronized, and files that have been deleted on one machine are deleted on the other machine. OtheRSync can resume without becoming broken or dangerous after an interruption or an error.
cleansweep is a set of scripts that help you clean duplicated files from your system. md5dir.sh gathers information on files in a directory. md5dirs.sh gathers information on files in multiple directories. samefiles.sh processes the data and generates information on file duplicates, filename duplicates, and unique files. clean_samefiles.sh cleans the files.
Perl Snapshot Is Not Incremental Backup backs up Samba (or Microsoft Windows) shares to central disk space using LinNeighborhood mount scripts as configuration files. The disk space is organized into multiple directories named after the server, share, and date. Each dated directory contains a snapshot of all the files on the exported share on the particular date. Disk usage is reduced by using hardlinks to keep multiple full copies of files available.
glucopy-glurestore is a set of scripts for copying and restoring a fully functional GNU/Linux (or other Unix-like) system. The glucopy script will back up all system content (system and user files), while the glurestore script will partition and format an identical system, restore the system and user files, and make the system bootable. The scripts are included in the HTML documentation.
