- CrashPlan PROe
If you have a large amount of data to back up to a offsite computer (such as another computer you own, or a friend's computer), you can save time and bandwidth by "seeding" your initial backup. Start the backup locally (which is much faster than backing up over the Internet), and then perform subsequent backups to the offsite location. This article walks you through the process of "seeding your backup".
Before You Begin
You must have a detachable drive that you can use to transport your backup between computers to use this process.
Step 1: Create The Archive
- From the CrashPlan app on the source computer, choose Destinations > Folders.
- Select a location to which you want to back up. Make sure you chose a location (i.e. drive) that you can transport or copy to the offsite destination.
- Click Start Backup.
CrashPlan creates your backup archive.
Step 2: Transport The Archive
It is important that you move / copy the entire folder that represents a computer's backup archives (the computer ID folder).
After backup is 100% complete, follow these steps on the source computer.
- On the Backup tab, click the pause icon at the right end of the backup status bar.
- If there is no backup in progress, the button looks like a right-pointing arrow .
- Clicking pause prevents the backup from restarting before the seeding process is complete.
- If your folder is on an attached drive (i.e., USB, firewire, network), eject or unmount the drive.
- Bring (or copy) your archive over to the destination computer (such as another computer you own, or a friend's computer).
Step 3: Attach The Archive At The Offsite Destination
You may notice these steps are the same as those you performed above to create the archive. That's okay! This is how you tell CrashPlan where to continue your backup.
- Connect the drive containing the archive to the destination computer.
- Open the CrashPlan app and go to Destinations > Folders.
- Choose Select.
- Navigate to the archive you'd like to attach.
Look for the folder that matches the source computer's ID: for example, 948212309528060501
- Click Ok.
Step 4: Resume Backup
On the source computer on the Backup tab, click the play button for the offsite destination.
Step 5: Remove The Folder Destination
After confirming that backup resumed, the original folder destination is no longer required to continue backing up. To remove the folder destination:
- From the CrashPlan app on the source computer, go to Destinations > Folders.
- Select the name of the folder destination created in Step 1.
- Click Delete to remove the folder destination.
A warning displays.
- Check I understand.
- Click Ok.
Removing the folder destination will remove the backup from the folder on an attached drive (i.e., USB, firewire, network). However, performing these steps will not remove the backup from the offsite destination.
Considerations When Seeding On Different Operating Systems
If the source computer uses a different operating system than the destination computer (e.g., from Windows to Mac), make sure both computers can read and write to the drive that holds your seeded archive. If you're working with a brand new external drive, in most cases, you don't need to do anything special prior to seeding; most external drives from the factory can be accessed by Mac, Windows, and Linux.
- Choose a file system that will work with both the source and destination computer's operating systems.
- Understand how file system limitations might affect your backup. For example, FAT 32 volumes are limited to 2 TB, but if your drive is smaller than that, this limitation will not be an issue.
- CrashPlan stores backup data in files of up to 4 GB.
