Multi-Destination Backup

Overview

CrashPlan works very hard to verify the integrity of your data and to repair corrupted archives before you need to restore. However, CrashPlan is not always able to recover from corruption before a restore is needed, hardware fails, system administrators fat-finger commands, and “lightning” can strike anywhere. So we always recommend that people use multiple backup destinations whenever possible.

Backing up to multiple destinations provides onsite backups for fast and convenient restores and offsite backups in case there is a problem at the local site. CrashPlan PRO supports multiple destinations to provide the highest level of availability and protection at no additional cost, because a client (or slave server) backup destination does not consume a seat license.

Your backup destinations can be a location with either PRO Server or a PRO Client installed, or even an external hard drive attached to a client. CrashPlan PRO is so flexible you can back to a combination of PRO Servers and PRO Clients, and locally attached drives.

Destinations can also be local or they can be remote. A local destination can be a computer on your local network (fast), a USB drive attached to your computer (faster), or another disk attached directly to your motherboard (fastest). A remote destination is one that requires an Internet connection and are generally slower than local destinations.

To maximize your protection and convenience, we recommend backing up to a combination of local and remote destinations.

Benefits

Backing up to multiple destinations provides the following these benefits:

  • Redundant backup destinations for maximum protection, speed and convenience
  • Flexible backup and restore options
  • Each destination works hard to verify the integrity of your data and fix problems whenever possible. If one destination cannot repair your data, another may have it.
  • If your initial backup selection contains a lot of files, backing up to a local USB drive means having the ability to restore faster in case of hard drive failure

Choosing Destinations

Reasons to back up to multiple PRO Servers:

  • You have an offsite location already has PRO Server installed.
  • You want to manage dedicated backups for more than 10 users.
  • You need to configure backup PRO Servers for different departments.
  • You need to scale your backup environment to accommodate user / storage needs.
  • You want to expand you your backup offering using 3rd-party backup destinations (for example, for service providers to allow backup from partners).

Reasons to back up to a PRO Client destination:

  • You have 10 or fewer users backing up.
  • You don't have sufficient computers to dedicate to backing up.
  • All users have the same backup, security or retention settings or they are capable of managing settings themselves.

Reasons to back up to a local destination:

  • Backups are much faster than over the Internet.
  • Restores are much faster than over the Internet.
  • Backing up to a local destinations means getting your files back faster than over the Internet to a remote destination.

Reasons to back up to a remote destination:

  • A remote backup destination provides protection should your office computers being wiped out by a flood, fire, power surge.

How It Works

The PRO Client automatically selects which location to back up to based on which location will complete first. If you are doing an initial backup to a local folder and to the PRO Server across the Internet, your PRO Client will complete backup to the local folder and then complete backup to the PRO Server. This ensures you're fully protected at one destination as soon as possible.
