ZeroScan Overview

ZeroScan is the revolutionary new technology in Synk 6 that can produce massive speedups in backups through totally skipping the scanning phase of operations.

In traditional incremental backups, the first phase is to scan through every file and folder, comparing it to the backup copy to see which things have changed. The items that have changed can then be copied.

In most cases, however, there's a lot of data that isn't changed, and only a very small amount actually needs to be copied. In fact, the amount of time spent scanning tends to be much larger than the amount of time actually copying the files that have changed.

ZeroScan eliminates this very expensive step by discreetly taking notes on which files you change as they change. When the time comes to do a run, Synk already has a list of every file that needs to be copied, so it can jump straight to doing the work it actually needs to do.

Synk Backup will automatically enable ZeroScan when it's confident that it will be safe. In Synk Standard and Synk Professional, you can manually enable and disable ZeroScan for each individual script in its "Options" tab. See "When can I use ZeroScan?" for important requirements before enabling this setting on any script.
