The CERN Tape Archive (CTA) is the archival storage system for the custodial copy of all physics data at CERN. CTA is implemented as the tape back-end to EOS. EOS+CTA is the CERN archival solution for LHC Run–3 and beyond.

For a general overview of CTA, see our Publications and Presentations. There is also some general Development and Systems Integration Documentation which complements what is on this site.

ArchiveBox takes a list of website URLs you want to archive, and creates a local, static, browsable HTML clone of the content from those websites (it saves HTML, JS, media files, PDFs, images and more).

You can use it to preserve access to websites you care about by storing them locally offline. ArchiveBox imports lists of URLs, renders the pages in a headless, authenticated, user-scriptable browser, and then archives the content in multiple redundant common formats (HTML, PDF, PNG, WARC) that will last long after the originals disappear off the internet. It automatically extracts assets and media from pages and saves them in easily-accessible folders, with out-of-the-box support for extracting git repositories, audio, video, subtitles, images, PDFs, and more.

A simple exemple to make Replication for RBD.

Based on this post from scuttlemonkey : http://ceph.com/dev-notes/incremental-snapshots-with-rbd/, here is a sample script to synchronize rbd image on a remote cluster (eg for backups). In the example below, the sync is made to an “archive” pool on the same cluster. (For remote host, you need to use ssh key.)
