Automatically backup your system to remote servers. Requires 10.5

Mathusalem is complementary to Time Machine as it backups automatically one or more directories of your choice to remote servers in order ensure extra safety of your most important data. It is an alternative to the Backup application that comes with .Mac / MobileMe if you need more control or features:

It supports a wide range of destinations: local drives, iDisk, WebDAV, AFP, FTP, SFTP or Amazon S3
It can generate archives in various formats: sparse or compressed .dmg and CPIO or ZIP archives
It generates fully self-contained backups i.e. data and settings which makes it possible to access them from any machine or even relocate them
It can restart a download or upload that failed or was cancelled by the user without having to restart the entire backup
It runs in low-priority mode on your machine so it doesn't hang your CPU or hard drive
It runs only when necessary (it is managed by launchd like other system services)
It is fully open-source which means no proprietary file formats (backup data files are plain XML)
It stores passwords in the Keychain
It reports detailed information on the backup progress
The command line tool version can be integrated in existing tool chains or used with launchd

The code still remains on the developers google code page and you can co trunk, compile for 10.6. Still remains my favorite

The Homepage ( says:


The source code is still available.

Update, the developer replied promptly to my question, the App was simply checking for updates.

Thumbs up for terrific Dev support!

This seems to be the start of a great program. I've been looking for a program that does just this. A light, simple program that can run seamlessly within the OS and use S3 as a compliment, not replacement, to Time Machine.

Mathusalem makes it easy to make multiple work flows for different local directories to backup volumes. For example, you can configure this program to backup your photos to your S3 account, an SFTP and then an external drive all within one interface.

It's also easy to restore to a previous backup, although the interface for doing so is not as sexy as Time Machine, by design I'm sure.

There are a few quirks to the program still and it seems its under active development.

Not quite sure why the App phones home when you launch it, made me a little weary to add my S3 codes but after further tests it seemed that it was probably just some sort of an update checker that couldn't be disabled.

It would be nice to see the transmit speeds/eta when sending your backup.

Overall verdict: recommended, and once they iron a few things out in their issue queue, this will be a "must-have".
