How CrashPlan PROe Works

How CrashPlan WorksContinuous Backup

Typical backups are resource-intensive and may run once or twice a day and render a computer nearly inoperable during those periods. CrashPlan PROe employs a continuous backup which is lighter and less obtrusive.
CrashPlan PROe detects when files have been added, removed or modified. It compresses and encrypts the files before sending them over the network. This occurs every fifteen minutes by default. Additionally, there is a daily disk scan to ensure that no files have been overlooked. And if the computer is turned off, the scan will take place when the computer is powered back on.
CrashPlan PROe is configured to back up user data only.  System data is not backed up.

Efficient Use of Resources

By default, CrashPlan PROe uses minimal CPU and network resources while your computer is being used. Users can throttle the network usage to prevent disruptions on home networks where there is typically less bandwidth than on campus.

Initial Backup and Subsequent Protection

After the initial backup is complete, only the altered bytes of a file are sent. Backups are verified routinely to safeguard against corruption. Should you need to restore a few files, you can use a secure web interface for recovery. For larger jobs, it is best to use the desktop software. See the CrashPlan PROe documentation to learn more about restoring files.
