Remove all copies of a file from a time-machine backup

It's nice to have time-machine as it works flawlessly most of the time. It's also very nice to go back in time to a specific version of a file.

But sometimes you need to get rid of ALL copies of a file for different reasons.

Here's how:

1. Startup time machine by either hitting the icon in your dock or clicking the time machine icon in your menubar and then selecting "Start time machine".

2. Navigate to the folder/file you want to delete and select it.

3. Click the "gears-icon" in the toolbar and select "Delete All Backups"

That's it. If you wanna play safe, do a free space wipe of your time-machine volume to ensure all evidence is gone ;-)

Move MOZY installation to another machine

Today I ultimately went from OSX 10.4 Server to 10.5 Leopard Server.

The whole process went smooth and without any major problems. However, I was a bit worried about moving Mozy, my online backup, to the new setup. Most of the files to be backed up, are stored on an atttached Lacie Biggest Disk with a Raid 5 setup, so the hash and the location of most of them wouldn't change.

For those of you who don't know Mozy go to www.mozy.com and download the trial. It's free for 2GB of storage and about 5 bucks a month for the unlimited service.

I really like Mozy. It's easy to set up and works flawlessly in the background. I regularly do some restores, not a single problem until today. But make sure this is just ANOTHER line of defense against data loss and not your ONLY ONE!

I didn't do an upgrade, instead I chose to start with a fresh install. Over the last 2 years with a 10.4 server I installed a lot of junk and the configuration was... I admit it, a bit scrambled.


So, here's how I moved my Mozy installation from 10.4 to 10.5:

1. Make sure to run a last backup on the old machine.

2. Copy the contents of the folder "/library/Application Support/Mozy/" to a disk accessible from your new system. Remember: This is NOT in YOUR home directory, it's in the SYSTEMS Library folder!

3. Make a new directory in your new systems /Library/Application Support/ folder and name it "Mozy".

4. Copy the files from step 2 in this directory.

5. Make sure your new system has the SAME computername as your old, otherwise Mozy will totally fuck it up.

6. Download and install Mozy.

7. Startup Mozy for the first time, click "Configuration" and let mozy figure out how much backup space will be needed. After that click SAVE, restart your server and you're done.
