What you can build

  • Build a small planner that takes source paths and retention intervals, then produces proposed rsnapshot configuration entries and a matching cron schedule.
  • Create a preflight tool that checks a chosen configuration and presents the documented test-mode preview for selected intervals before an operator schedules backups.
  • Turn configured intervals and retain counts into a timeline showing snapshot names and how lower-level snapshots feed higher-level rotations.
  • Build a file browser that lets a user choose a snapshot and path, then produces a restore request with the selected source and destination for an operator to review.
  • Create a local comparison tool that accepts two snapshot directories and outputs a file-by-file difference list to help identify candidates for recovery.

Try this prompt

Build a small local backup-plan generator. Take a CSV inventory of source paths, destination details, and requested interval retention counts; produce a proposed rsnapshot configuration and cron schedule using documented configuration concepts. Preserve any existing configuration by writing a separate draft, never launch a backup, and show the user how to validate the draft with rsnapshot's documented configuration check and test-mode preview. Include input validation and a sample inventory and output.

Get started

  1. Check prerequisites and installation

    Follow the repository's INSTALL guide. The README documents Perl and rsync, and describes backing up remote machines over SSH.

  2. Configure and validate

    Edit the installed rsnapshot.conf, using the man page for configuration options. The README documents a configuration sanity check and a test-mode preview for an interval.

  3. Schedule after review

    Review the test-mode preview, then schedule the desired intervals with cron. The README includes example schedules and explains how retain settings control snapshot counts.

License & notes

GPL-2.0The software is GPL-2.0 and does not require a paid API or model. Budget for the machines, storage, and network capacity used for backups; cloud hosting or storage, if you arrange it separately, may have its own costs. Commercial use is permitted. If you distribute modified or derivative software, GPL-2.0 obligations apply, including licensing the distributed work under GPL-2.0 and providing corresponding source as required.

  • Requires correctly configured storage and access; remote backups use SSH. It does not provide built-in cloud storage or full-disk imaging.
  • Hard links reduce space where possible, but storage use depends on the data and filesystem. The README warns that link_dest has a limitation when a remote host is unavailable.
  • GPL-2.0 permits commercial use, but distribution of modified or derivative software carries license obligations, including source and licensing requirements. No warranty is provided.
