DNS has, unfortunately, always had some inherent weaknesses because it’s transported in plain text. DNSSEC has never attempted to address that (crazy, I know). Encrypting all DNS traffic means a fundamental change to the security of the system on the whole and a strong improvement.It doesn’t work at all on my Mac connected via my Time Capsule. Perhaps it was meant to be used on public Wi-Fi hotspots? Encrypting DNS
Last year my friend had to deliver some distressing news to his wife. The external hard drive on which he had been storing their family photos failed. The problem had started a few weeks earlier when his wife mentioned that the hard drive was making some strange noises. My friend had planned on backing up the disk to DVD but being a busy IT manager he just never got around to it.
At that time I remember thinking smugly to myself, if only he had a Mac with Time Machine he would have been protected. I realized later on that I was wrong. I use Time Machine to backup three of the household Macs to Time Capsule once a day. This protects my data should the local hard drive fail but I lose ALL of my backups if the Time Capsule disk fails. I wanted a backup system that was more robust; one from which I could survive a local disk and local network storage failure. That’s where Backblaze comes in.
Backblaze is a cloud based service that backs up everything on your computer except your operating system, applications, and temporary files. The service costs $5/month ($50/year) and provides three methods to recover your data. You can download your files from the Backblaze web site, order them delivered to you on DVD ($99, 4GB max) or for a $189 fee Backblaze will deliver your files on a 500GB Western Digital external USB hard drive. The 500GB seems quite reasonable to me considering that I now have 74GB of data (70GB of photos, 4GB of documents) stored on Backblaze.
After registering for the service I downloaded and installed the Mac version of the Backblaze client. The Mac client is Intel only. Backblaze also offers a client for Windows XP, Vista and Windows 7.
One of the first things I did was setup the frequency of backups. By default, Backblaze simply backs up all the time so you don’t have to remember. But if you wish, you can schedule Backblaze to backup at a convenient time (like the middle of the night) or only when you click “Backup Now”. I chose the “Continuously” option. I take a lot of photos during the summer and I find myself emptying the SD card from my Nikon at least once a week.
Backblaze will backup any USB or Firewire drive I have attached to my computer as long as I leave the external hard drive attached to my computer all the time. It was simple to add my 500 GB G-Drive Q Firewire HD to the backup queue. Good thing too, since this is where I keep my digital photos.
To prevent users from abusing the service network (NAS) drives, Time Machine drives , remotely mounted computers or volumes, or shared volumes do not get backed up.
From the setting screen the user can also set options to control how much local network bandwidth is dedicated to backup as alerts for failed incomplete backups.
By default Backblaze backups everything on the main hard drive except for applications and the operating system. It also does not backup files over 4GB. Backblaze claims that most users do not create files larger than 4GB. I can’t disagree with that and they do make an except for iPhoto library files.
I don’t really need every user folder to be backed-up. My iPhoto library are stored respectively in the Photos and Documents folders on the externally drive. Unfortunately the mechanism that Backblaze uses to mange what gets backed-up and what doesn’t is not easy. I had to explicitly exclude all the folders that I did not want backed-up — on both the local and external drive. If you have more than one user on the local machine this can take considerable time.
The Backblaze console provides a fair amount of reporting including how much storage each type of file will use and which files are scheduled for backup. This was an eye opener for me. I did not realize how large my iPhoto library had grown. A drive failure would surely be a painful experience.
I’ve been using the Backblaze service and software for just a few weeks and so far I have no had any problems. Of course, the true test of service is how easy it is to service a hard drive failure. Knowing that I can rebuild my machine and recover all my files with a single click gives me piece of mind.
Everyone has predictions for MacWorld 2008. The pundits are making more predictions about possible or probable Apple product announcements than actual Apple product announcement in 2007 and 2008 combined. So let me enter the fray. Here are my predictions (completely based on other predictions I have read).
- Updated MacBook Pro.
- All aluminium
- Better battery life
- Revamped Mac mini
- All aluminium
- Time Capsule form factor
- Better graphics and updated ports
Predictions of an Apple media center ( isn’t that Apple TV? ) or of a mini Mac Pro will prove to be incorrect. There will be no new Apple Displays or iPod Nano. Of course my predictions have a 50% margin of error. The only thing I know for sure is that aluminium is the new white.
This is a followup to the problems I was having with Time Machine backups to Time Capsule. Time Machine would start preparing a backup and after about 10 would fail. After a few weeks of failed backups or backups taking hours I called Apple support. They had me try several things including reseting Time Capsule. One of the things that we tried was using the Disk Utility to mount the sparse bundle files as a OS X volume. That’s when I got this error message.
After almost an hour on the phone with first level and second level support I decided on a drastic course of action. I used the AirPort Utility to erase the Time Capsule disk. Once that completed I configured Time Machine to point to the Time Capsule disk and Time Machine has successfully completed two weeks worth of backup.
