I recently started using Backblaze a cloud based backup system. I wanted an offsite backup to my Drobo. Backblaze will not accept any backups from drives that have a Time Machine folder on them. Up to this point I have had no problems doing my Time Machine backup to the Drobo. But, when I investigated my options, I found the Backup / Time Machine Volume option from the Drobo Dashboard; Volume section. I successfully added a volume, named it Time Machine and tried to do a backup. This failed two times, but in different ways.
The first said:
“Couldn’t Complete Backup: Files can’t be copied onto a the backup disk because it is read-only. You may need to repair or erase the disk using Disk Utility. If the disk can’t be repaired, select a different disk.”
Second time, I erased the volume and created another:
“An error occurred while copying files. The problem may be temporary. If the problem persists, use Disk Utility to repair your backup disk.”
I waited, tried again, got the same error. I then tried using the Utility to repair the disk. It finally crashed the Disk Utility after seeing that there were a ton of errors that were not fixable.
I would like to continue using the cloud backup, I need a secondary Time Machine Volume to do so. And I would like the Time Machine Volume from the Drobo Dashboard to work correctly.
Anything you can see that I have done incorrectly or a way I can repair it? My only other thought is to some how borrow multiple drives, back up the Drobo to them, erase the disk and reformat from the start. Not a great idea showing that I have maybe 5-6 TB of data.
Also, everything is the latest and greatest version of software for my Mac, for the Drobo 5D, and for Dashboard.
