I currently use dirvish to do this using rsync and hardlinks, though I used to use custom scripts. This way I can keep dailies for the last week, weeklies for the last month, and monthlies for the last year all without wasting too much in terms of disk space (for my current setup, it's about 3 times the size of the data I'm backing up with about 10% churn on a daily basis, but this is probably overkill for most people). > Being able to restore to an arbitrary point in time is useful to me. > And knowing that I have media that I can move to another location is > also important. Tape can still be good for easy media shifting and long term storage, but it requires administration that the automated rsyncs don't. It's all a trade-off. Kevin.
