Synchronize. Backup. Bootable Backup.
Whatever your backup or sync scenario, ChronoSync has got you covered!
Modifier Assistants

MODIFIER ASSISTANTS - Choose some or all of your previously created tasks and apply mass changes like error handling behaviors, task monitoring, enabling Admin Access or setting up schedules.

Incremental backups

INCREMENTAL COPIES - ChronoSync performs incremental backups meaning only files that have been modified since your last backup will be copied. This speeds things up and cuts down on the storage requirements for your backed up data.

File state comparisons

CHANGE DETECTION - Instead of just comparing files against each other, ChronoSync creates a snapshot and compares the existing state of your files against their last known state, ensuring that a wide variety of changes are detected.

Metadata synchronization

METADATA CHANGE DETECTION - ChronoSync detects metadata changes such as access permissions, locked states, Finder labels, tags, Spotlight comments, etc. and will intelligently apply metadata to a counterpart file if that is all that has changed.

Faster file scanning with SmartScan

SMARTSCAN - Performance jumps to a whole new level with SmartScan, an advanced algorithm for analyzing a volume for changes. While SmartScan won't copy your files any faster, detecting which ones need to be copied can see dramatic speed improvements.

Increased Copy Speed

CONCURRENT COPY - Multiple files can be copied simultaneously, greatly increasing the efficiency of your syncs and backups. You’ll see the greatest improvement when dealing with network or cloud-based connections.

Pick up where you left off

PROGRESSIVE SCANNING - If a synchronization or backup task is prematurely terminated, progressive scanning will pick up where it left off and scan only those files not scanned in the previous run.

Detects conflicts during synchronization

CONFLICT DETECTION - Many synchronization programs are incapable of accurately detecting conflicts - situations where a both files have been modified. ChronoSync's unique change detection algorithm makes it ideally suited to detect and report such conflicts.

Copies files to temporary location

SAFE COPY - Data is first copied to a temporary file. Only once the copy has been successfully completed will the destination file be replaced. This keeps your destination file intact in case there is some error or connection loss encountered during the copy.

I/O Throttling

I/O THROTTLING - When enabled, disk I/O operations are performed at a low priority, allowing you to continue using other applications unimpeded. This feature is intelligent and will only slow down when it detects you are actively using other applications.

Freeze File System

FILE SYSTEM FREEZING - If using APFS, this feature will take a snapshot of the file system first. This guarantees the destination will mirror the source at the exact moment the sync/backup begins. Even if the computer is being used when the sync/backup is running.

Detect File System

DETECT FILE SYSTEM - ChronoSync not only works using the new APFS under Mojave, it still works optimally using HFS+ with older versions of macOS and chooses different program logic depending upon the file system being used.
