rbackup - time-stamped, hard-linked backups powered by rsync

rbackup

rbackup is a lightweight, rsync-powered backup utility that creates time-stamped backups.

Features

It can save backups to your local filesystem (probably an attached USB device) or to a remote host.

Backups are saved in time-stamped directories. Backups are cheap on storage, because hard-links are used for files that haven't changed between backups.

Rewrites index.html to with CSP strict-dynamic enabled
/**
* Usage: node csp-strict-dynamic.js dist/index.html [path/to/nginx.conf]
*
* Replaces all external script tags in index.html with dynamic loaders, calculates their SHA 256 hashes, and adds those
* hashes as allowed script sources + strict dynamic. Also works for inline scripts.
*
* Your index.html and/or given nginx/apache config file should contain your CSP policy with a script-src section like below:
*
* script-src 'strict-dynamic' {{csp-strict-dynamic-sources}};
