After about five years of deliberation I’ve made the switch from a Windows laptop to the new MacBook. My first thoughts are that it’s exceeded my expectations by miles! I love the way the OS looks and it’s great to use, and the switch was far more seamless than I could have hoped.
On to my actual point. The article in issue 288 about backups was very informative and solid advice; as an IT worker, I fully appreciate the importance of regular backups. I’ve set up Time Machine to use my NAS drive, but that’s quickly filling up. Is it possible to configure Time Machine more than just on or off? Ideally I’d like to have it do a ‘delta’ backup a few times a day and then a full-drive backup once a week. If this isn’t possible with Time Machine, could you recommend a tool or utility to do this for me? I don’t mind paying for a good tool that meets my needs! Mike Witts
Alan Stonebridge says Time Machine performs a full backup the first time it runs (excluding anything you explicitly tell it not to include). From then on, OS X tracks which files change and backs up incrementally on an hourly basis. Time Machine uses ‘hard links’ to maintain multiple references to data that remains unchanged over time. This enables it to keep a complete record of your Mac’s storage for each point in time that it makes a backup without unnecessary duplication of unchanged files. With a little time spent configuring it, Carbon Copy Cloner (bombich. com) can be scheduled to perform backups to multiple destinations and at whatever intervals you choose, such as every four hours, not just hourly.
Time Machine alternatives such as Carbon Copy Cloner are also able to back up to a schedule, and not just hourly.
