ChronoSync is an application that runs on a Mac that can synchronize, backup, and create bootable backups. ChronoSync can synchronize or backup to almost anything you can connect to your Mac. That includes folders on your Mac, other Macs, PC's, external drives, NAS drives, or anything you can mount to your Mac. Even sync to iPads and iPhones using the combination of ChronoSync and InterConneX. If you’re unsure if ChronoSync can meet your backup or synchronization needs, just contact us and we’ll be glad to help.


Synchronize your Mac files

SYNCHRONIZATION. You synchronize files when you need to store files and actively use them in more than one location, such as your desktop computer at work and your laptop at home. Modified files get copied back and forth between two targets.

Backup your Mac files

BACKUP. You backup files when you need redundant copies of your files to protect against data loss in case something goes wrong. Backing up will copy modified files from a source to a destination.

Bootable backup your system drive

BOOTABLE BACKUP. A bootable backup is a backup or clone of your entire system drive. In addition to backing up all your files, a bootable backup allows you to boot directly from the backup drive so you can still use your Mac if your primary drive fails.

Bootable backup over the network

REMOTE BOOTABLE BACKUP. A bootable backup is typically performed to a hard drive connected to your computer. However, by adding ChronoAgent to the mix, ChronoSync can perform a bootable backup over a network to a hard drive connected to another Mac! No other backup app offers such a simple solution for bootable backup over a network.

Backup and sync to iPhone and iPad

iPhones & iPads. InterConneX is a free iPad and iPhone app in which you can store, manage, and share files and folders. With ChronoSync on a Mac you can automatically backup or synchronize files and folders between any iOS device running InterConneX.
