"Though we seemed dead, we did but sleep..." -- Shakespeare, Henry V
Dirvish for Network Backups
6:30pm Tuesday, Sept 18th -- Eugene City Brewery (downstairs)
Dirvish is a free, open source network backup system using commodity
hard disks as backup media. Dirvish is a Perl wrapper around rsync,
managing scheduling, file selection, and expiration of old images.
Rsync hardlinking allows hundreds of full backups to fit on one backup
disk, while conserving network bandwidth by moving only the changed
portions of files. Backup images are exact duplicates of the source
filesystems, simplifying verification and restore. A complete backup
of 8 machines with 150GB of data takes about an hour. Dirvish is used
at sites as small as single-machine SOHO users, up to terabyte server
farms like Oregon State University's Open Source Labs.
