rsync-incr is a linux wrapper shell (bash) script around rsync to perform automated, unattended, incremental, disk to disk backups, automatically removing old backups to make room for new ones. It produces standard mirror copies browsable and restorable without specific tools.I have been using it in production daily at work and at home since 2004.
I wanted to have a backup system with the following properties:
- standard based on standard tools (rsync), and restorable with only standard tools.
- simple as possible.
- automatable to be run daily (or more) by crontab, managing error conditions reliably so we can mail on errors, and making automatically room for new backups.
