Incremental Rsync

Snapshot backups with traffic shaping and restore

ⓘ

Documentation is being modernized. Expanded guides, configuration references, and usage examples are on the way.

Overview

Incremental Rsync (IRSYNC) is an incremental backup utility built on rsync with integrated Linux traffic control (tc) shaping to regulate bandwidth consumption during transfers.

IRSYNC creates incremental snapshots using hard links, enabling storage-efficient point-in-time restore without duplicating unchanged files. It includes native MySQL backup support through mysqldump and mysqlhotcopy, making it suitable for backing up both file systems and databases on production servers.
