rsync redux

Completed the new backup system last Friday. Now have a perfect daily mirror of half a dozen backup locations, as well as incrementals rewinding every day for a month. The cool thing about rsync is that it doesn’t need to copy GBs of data to make a mirror – uses checksums to send diffs, so a day’s changes are updated into the reservoir in seconds. Any files destined for deletion or change are copied into a folder named for that day of the month. My script steps through an arbitrary number of backup locations, and maintains separate mirrors and incremental sets for each. Fun to be shell scripting again, rather than PHP. It’s been a while. Running as a crontab, trouble-free so far. So much sweeter than the DVD backup system we had on the old Win2K server, which required my physical presence.
