But because underneath the surface it is using hardlinks (basically advanced aliases) to the last backup that it made, it’s actually only storing fresh copies of the files that have been changed since the previous time a backup was made, and the rest are hardlinks to the previous backup.
The upshot of this is that you can store around 150 copies of your startup drive with 500GB and 1 million files on it on your backup drive with 700GB free, instead of the 1.5 copies you could store with traditional backup software.
Since the root will never have any items deleted from it, anything else you are storing on that external will not be affected by any Syncs to that destination disk.
Incremental Snapshots: (preserves all you file’s history while efficiently using space) At first it seems impossible, but the Incremental Snapshot feature allows you to store what seems to be 15TB of information on a 2TB drive.
This allows you to preserve versioned changes on your backup disk for months.
If you are working with your files and you make a mistake, you don’t want that mistake to be automatically reflected in your backups, but at the same time you do want to preserve the latest work you have done.
Experience firsthand the life-changing event documented in Tony Robbins: I Am Not Your Guru.
Embark on a journey – 6 days LIVE with Tony in a supportive environment of total immersion!Did you ever try to copy your System folder for example? It will even struggle with large folders with lots of files in it, and the copies are not resumable if you have to restart them. If you want to make reliable and exact duplicates of anything you can throw at it, this is the way to do it.It will be happy backing up petabytes of data, or complex folder hierarchies with arcane filesystem metadata, permissions, and ACL’s set, and reproduce an exact, indistinguishable, duplicate.The best way to use this is to set up a daily schedule to make a Snapshot of your source drive, and just leave it there.You will then have a daily timestamped backup of your data, and you can go back at any point and pull out preserved copies of any particular files that you want.Direct Cloning: (useful for a fast bootable backup) Make an exact duplicate of a folder or disk, fast.
