    Choosing Multiple Destinations

    Applies to:
    • CrashPlan for Home


    CrashPlan is extremely flexible. You can back up to a computer you own, to a drive on or attached to your computer, to a friend's computer, to CrashPlan Central, or to any combination of these destinations.

    Here are some things to keep in mind about onsite and offsite destinations.


    CrashPlan is designed to allow you to back up to multiple destinations, so while you have your files stored safely on CrashPlan Central, you can also have a copy of it sitting on your desk on an external drive.

    Destinations can either be onsite, meaning the destination is located in the same physical location as the computer it backs up, or offsite, meaning the destination is stored in a physical location separate from the computer it backs up. The advantages of both onsite and offsite destinations is explained below.

    Advantages Of Onsite Destinations

    • Faster backups. Backing up over a local network takes less time than sending your files over the Internet. Depending on the amount, backing up locally can be done in a few hours rather than days or weeks.
    • Faster restores. Restoring files from an onsite backup destination is much faster than restoring from an offsite one… requiring minutes instead of hours or days.
    • Convenient. A local destination is very convenient when you need to recover from a computer crash and restore a lot of files.
    • Available. An onsite destination is easily accessible to you, presumably under your direct control and therefore always available.

    Advantages Of Offsite Destinations

    • No single point of failure. Because local disasters typically affect all the computers in a single location, backing up to offsite destinations reduces the risks of putting all your backup eggs in one basket.
    • Out of harm's way. Having a couple of offsite destinations as part of your backup strategy ensures that you can retrieve your files in the event of a disaster that affects an entire facility or region.

    Recommended Backup Solution

    The ideal solution is backing up to three places. For example:

    • Two places stored onsite: on your computer (your original files) and on a backup to an external hard drive or device.
    • One backup stored offsite: such as CrashPlan Central, on a friend's computer, or an off-site hard drive.

    This way, no matter what the circumstance, you always have redundancy when one backup is inaccessible or a setting that affects what's stored in the backup gets changed. 

    Using backup sets, you can choose to fine-tune the files backed up to each destination. For example, if you have information you only want stored in one location, or a couple files you only need backed up once a week instead of continuously, you can tailor CrashPlan's settings to your needs.

    Destination Options

    When... Use this option Advantages Considerations
    You do not own another computer you can back up to or you don't know anybody willing to be a backup destination Back up to CrashPlan Central Requires no permission to be granted and offers offsite protection for a small fee.

    Your files are stored in a secure data center that is resistant to most, though technically not all, manners of disaster and mayhem.

    If you have lots and lots of files to back up, backing up to CrashPlan Central could take a long time. Restoring an entire archive could take a similarly long time.
    You want to back up your laptop to your desktop Back up to another computer that you own Because this is a computer you can access at any time, you won't have to wake up anybody in the middle of the night when you accidentally delete that presentation you've been working on all night. And you won't need to send an invitation or get permission to use that computer as a back up destination.     If both computers are in the same location, your backup is vulnerable to disasters that affect the whole building. For example, you're protected in the event of a hardware failure, but not fire that damages your entire home.
    Your college student wants to back up her laptop to the family's desktop computer back home Allow someone to back up to you You can be a destination for someone else.     You'll need to have your desktop computer available in the event of a disaster and your student needs to restore her files. Because backing up and restoring takes place over the Internet, the initial backup and a complete restore could take many, many hours.
    You want to back up to an offsite location and are willing to let others back up to you Back up to friends and neighbors By backing up offsite, you can protect yourself in the event of disasters that might affect your home like theft or fire. If you are able to back up to friends who are very far away, you are further protected against disasters that might affect the entire region like hurricanes, floods and wild fires.
    Your archive is encrypted, meaning no one but you can see your files, and your files are completely safe and sound at a trusted destination.   
    You'll need to have your desktop computer available when someone needs to restore files. Because backing up and restoring takes place over the Internet, the initial backup and a complete restore could take many, many hours.
    You want to backup to an external hard drive     Back up to an attached drive or shared folder Backing up to an attached drive is a fast way to get a lot of files ready to go offsite onto a remote PC.     Your hard drive could get lost, stolen or damaged.
