Use an encrypted disk image
Authored by: dbs on Sep 28, '07 12:49:53PM

A simpler approach is to install MacFuse and use the ssh filesystem to mount the file system on your machine. Then just use CarbonCopyCloner to backup to an encrypted disk image. You'll keep all your HFS+ metadata (previews, icons, etc.), get incremental backups, and have everything encrypted with the passwords stored in your Mac keychain. I use this approach to backup to a local NAS over samba.

Yeah, but when you're backing up 10G+ every day, it's a little impractical to backup the entire 10G disk image when you've only changed 350kb of data.

I have a private remote server that I use rsync + ssh to send my changed data to every night. If I had to do the entire 10G, it'd take a full night. Using rsync, it takes about 5-20 minutes (depending on how much data is being sent).

OP, Thanks for the tip btw :)

You don't have to copy the whole disk image whenever you change something on it. You simply mount the image remotely, change what you want to change and unmount it again.

Mounting and unmounting takes somewhat longer with encrypted images but not dramatically so.

As even a very small corruption of this encrypted disk image file can make your data un-retrievable, I would not want to rely on this method as my sole back-up and at least combine it with a local, un-encrypted back-up, or simply with other independent back-ups.

Precisely, it's not ideal to rely on this as your only backup method. I'm using this in addition to my local (non-encrypted) backup to an external drive. The idea is it's a good insurance policy in case your home gets robbed and they take your external drive as well. Hopefully it will never be needed anyway, but I sleep a bit safer at night knowing I have something out there just in case...
