How to back up your Mac - Remote Backup

Remote Backup

If you’ve followed along this far, you know we mentioned previously why you need several styles of backup, you’re rocking a solid clone backup, and you’ve got Time Machine covering multiple versions of at least your most important files.

That should be enough, right?

Bzzzt!

What could possibly happen to your Mac that could also affect the backups sitting next to it (or even in the same office or home)? Wait — let’s not cite potential specifics and jinx anybody; surely you’ve thought of some ugly possibilities.

That’s why we need the remote backup.

Materials Needed

Broadband Internet

If we’re going to do this automatically, the only practical way to do it it is via an online backup service

Similarly, this is probably only practical if you have a broadband internet connection of some kind - if you don’t, your best bet is probably to do multiple clone backups, and rotate them back and forth between home and office or something. Feasible, just not automatic.

In fact, the bigger the internet pipe you have, the more you may want to consider backing up in this manner.

Remote Backup Service

There are several of these. The one I’m most familiar with is Mozy. Mozy is free for 2GB or less, but if you’ve got less than 2GB of data to back up you’re not downloading enough movies and music you may just want to skip this and backup to a thumbdrive or something.

Even if you’ve got more than 2GB, Mozy is plenty cheap - $5 a month for unlimited storage. Peace of mind for less than the price of two grande moccachinos.

As I mentioned, there are plenty of alternative choices. Mozy was one of the early ones, and it works well enough I stick to it. If you’re shopping around, however, here are some factors to consider:

• Security - Are your files encrypted before they’re transmitted and stored?
• Cost - There may be better alternatives than “all you can eat for $5″, but only if what you do eat is less than $5 worth.
• Client software - As usual, Macs were not the first target market for these services. Double check places like Versiontracker and Macupdate to get opinions on how nicely their client software plays under OS X. One particular peave is how much bandwidth and CPU they take while they’re running, and how well they limit themselves when the machine is busy. I don’t want my backup to get in the way of my doing work, by hogging all of the CPU and/or all of the internet connection.
• If a catastrophe happens, and you need all of your files faster than you can download them, is there some option to get DVDs or something overnighted to you?

Dot Mac

I’ve always been inclined to think of .mac as a poorly priced mail and limited web hosting service, which never interested me much (since I’m in the web hosting business), but all that changed when I went from having one Mac to having a couple.

In particular, I discovered the joy of syncing to .mac. While syncing isn’t quite backup, it may be the most convenient way of being sure that things like keychains and preferences are kept up-to-date remotely, in addition to stuff like contacts, calendars, etc. This is stuff that’s close to the heart of OS X, and .mac syncing is far more likely to do that properly than an OS X backup client from a company whose customers are 80%+ Windows users. I don’t know if I’d recommend buying it if you have no other use for .mac (I’m lying, I would), but if one of the other features is something you want, it’s a no-brainer.

Setup

The details of the setup are going to depend on what service you use, but the basics are deciding what you want backed up, and when you want it backed up.

It pays to remember that these things are slooooooooow… Even if you’ve got a fat connection to the internet, you don’t want it to use a whole bunch of the bandwidth. Also, doubtless there’s stuff that’s easier to recover than downloading it from a remote backup — reinstall the system to get system files, reinstall applications, etc.

Focus instead on what is REALLY important — documents, financial application data, maybe photos, etc. Just the stuff that would let you get back running if you lost everything else. If you’re using .mac, that may be an even shorter list.

In my case, that runs about 8 - 10GB.

Again, be prepared for this to take a real long time to get started. It takes days and days for my 8 - 10GB to get sent up to the Mozy servers (and I’m on a pretty darn fast connection). But remember that that only has to happen once. After it’s done, the backup just fires off when it sees something’s changed, and usually when the machine is sitting idle. I seldom notice it now that the initial sync is done.

Except for the peace of mind.

Are we done yet?

Yes, and thanks for your patience. Go forth and be inadequately backed up no more.
