I'm an advanced user, and I clone my drives, what should I know?

In order for Backblaze to function properly, the .bzvol file must be excluded from all cloning programs so that specific Backblaze data does not get cloned. Some of the more popular cloning options are: 

 

Carbon Copy Cloner: 

Carbon Copy Cloner 3.4.5 and later automatically excludes .bzvol from clones.

 

Super Duper Cloner: 

1. Make a new copy script.

7. Click "Close" then "Save."

8. Change the name to something descriptive, like "Backup all files except .bzvol" and click "Save." Make sure to save it in the Copy Scripts folder.

9. Back on the main panel, choose the script you just created as your copy script.

These steps will prevent SuperDuper from copying the .bzvol folder, but it will not remove any that have already been copied over to the destination drive. To remove the existing one, in the Finder, pull down the Go menu and choose "Go to Folder." In the field, type /Volumes/MyBackupDestinationName/.bzvol/ (replacing MyBackupDestinationName with the drive that is the recipient of the clone) and click Go. In the resulting open folder, delete bzvol_id.xml.

 

 

Drobo Copy: 

1. Open DroboCopy and select "Advanced Settings" .




2. Add the .bzvol exclusion by clicking on the Add Exclusions button. 
Type SHIFT + COMMAND +G at the same time to bring up a 'Go to the folder' dialog. Enter '/.bzvol' and click Go.
That will bring you to the .bzvol folder. Click 'Open' to add it to the DroboCopy Exclusions.

If you use cloning software that's not listed here, here are some generic instructions:
• Instruct the software to not copy the .bzvol folder from the source drive to the destination drive (it may be called an ignore, exclusion, etc.)
• Manually remove the .bzvol from the destination drive - In the Finder, choose "Go" -> "Go to Folder". Enter "/Volumes/DriveName/.bzvol". Delete all files in the .bzvol folder
