CrashPlan PROe Backup

How It Works


​​

Continuous backup

CrashPlan PROe provides “continuous backup” which is different from other, more traditional backup applications. Rather than start a resource-intensive backup session once or twice a day, as for instance with Second Copy, CrashPlan is much more lightweight and unobtrusive. 

CrashPlan PROe’s real-time file watcher works directly with the tools built into your computer's operating system, which means it makes minimal demand on your computer and can easily work in the background without you noticing. It listens to your operating system to learn when files have been added, removed or modified. It queues up the eligible files, then compresses and encrypts the data prior to sending them over the network. This happens every fifteen minutes by default.

Just to make sure no files were missed, there is a once-a-day disk scan to account for any changes that might have been overlooked. This usually happens around noon each day. If your computer was turned off, that scan will take place later in the day.


Initial backup, subsequent protection

After the initial backup after the software is first installed is complete, from then on only the changed bytes of any given file are sent. Additionally, on a per-device basis, CrashPlan PROe provides de-duplication to make backups more efficient. De-duplication prevents CrashPlan from backing up duplicate data when two or more files in your backup selection include the same information. This reduces the amount of storage space needed for your backup and speeds up the backup process. The integrity of your backups is verified regularly by the software. Any corruption in the backup archive will be identified and the original files will be backed up again to ensure protection. 


Resource efficient

By default, CrashPlan PROe uses minimal CPU and network resources while your computer is being used. By default the network usage is limited from all locations to prevent disruptions on home networks, too.

 

Restoring

To restore data, you can use the desktop software to select and restore a file or files, or for restoring just a few files you can use the secure web interface. The web interface also allows you to recover files to a different workstation . See the page on restoring files to learn how to get back lost or corrupted data. Important Note: If you have any HIPAA data on your system, you will not be able to restore via the web. You will need to use the client application on your computer. See the Frequently Asked Questions for more information.
