BackupAFS

Given the ever decreasing cost of disks and raid systems, it is now practical and cost effective to store backups on a (remote) server's local disk or network storage.

BackupAFS is a high-performance, enterprise-grade system for backing up OpenAFS volumes to a such a server's disk. This is a strategy commonly known as "disk to disk", or "disk2disk" backup, and thanks to the low cost and high performance of modern hard disks, is both fast and economical. BackupAFS is highly configurable and easy to install and maintain.

• Changed order of operations.
• Always create .backup volumes; this way, in the absence of any other backup product, we know that any volume without a recent .backup volume doesn't belong to any volumeset being dumped.
• Look at last update of .backup volume, not RW (Jeffrey Hutzelman, <jhutz@cmu.edu>, openafs-info, 2005-12-04).
• Deal with volumes that have "Never" been updated.

• Fixed minor perl annoyances.

Known issues:
English is the only language supported. Translations for other languages are happily accepted.

• Volume dumps may be large. As large as your cell's largest volume, for full dumps. As large as the amount of changed data for incrementals.
• Don't be surprised if an incremental does not dump anything. If a volume has not been modified since the last time it was dumped, we don't back it up. We do create an empty directory for the volume as long as it exists, to permit the CGI to browse parent dumps.
