After much time, I have finally completed my guide to using Dirvish for snapshot backups. The guide covers what a snapshot is and how it’s created, then walks through obtaining, configuring, and using Dirvish features for creating snapshot backups nightly. In the future I may add rsh and rsyncd as transports. rsh is nice for speed when you really cannot handle the overhead of encryption, but that’s rarely a huge issue today. rsyncd as a transport is interesting, but it’s unencrypted, must be setup on each target system, and either OpenSSH or rsh still need to be configured for pre- and post-scripts to run on the target system.
