MacDaddy’s Mac Backup Guru may encourage you to back-up your data more frequently — and if you’re not already backing up, start doing so immediately.
The useful utility is designed to, as you might guess from the name, back up files and disks. With a single Start button, you can sync the contents of any source with its backup destination using the app. Disk backups of startup drives are bootable with the Mac Backup Guru. If there's any inconsistency in the size or modification date between any files, the Source file replaces the outdated destination file. Following the initial cloning, syncs take minutes instead of hours.
Disk backup via cloning requires that the entire contents of the source overwrite the entire contents of the destination drive. Disk backup via sync requires that only the changes since that last backup overwrite the appropriate part of the destination drive. Backup via sync requires that the initial backup be cloned, but all subsequent backups can be synced.
Syncing ignores the vast majority of files that are identical on the source and destination, and it concentrates on only those files that have been updated or added since the last sync. This backup method is comparable to MPEG video compression, where only the difference between successive frames is recorded (until a new I-frame), according to the folks at MacDaddy.
Mac Backup Guru for macOS was recently revved to version 6.0. The upgrade offers brings faster backups, user interface improvements, an updated copy engine, and an improved incremental backup process.
Mac Backup Guru 6.0 costs $29 and requires macOS 10.9 or higher. It’s available directly from the product website. A free trial download is also available.
