• Unfinished Large Files
    @David Gugick Does the consistency check flag or somehow warn of unfinished files in a Hybrid backup scenario? I'm using CBB for Windows Hybrid backup to 1) encrypt my data, 2) back it up to my NAS, and 3) back that up to Backblaze S3. Is it possible I have undetected unfinished files on BB?
  • How to test bare metal restore using Hyper-V on PC
    @David Gugick, Support got up with me quickly with exactly what I needed. In case others run into the same problem, here is what I did differently: Instead of using the Hyper-V Quick Create, I used the Hyper-V Manager to create the VM, and THEN connected to the vhd. I am now confident I can depend on CBB for a bare metal restore should I ever need it.
  • How to test bare metal restore using Hyper-V on PC
    Will do. The vhd version just failed at 33% complete.
  • How to test bare metal restore using Hyper-V on PC
    @David Gugick, I followed the instructions in the blog post for creating a vhdx. The only difference is Windows 10 Hyper V Quick Create doesn't now give an option for generation 1 or generation 2. I assume that has changed since the blog article was written in 2005. At any rate, I ran Hyper V Quick Create twice again and it failed at about the 25% completion mark. Is there a way to test the integrity of the vhdx?

    In the meantime, I plan to do another CBB restore, with vhd instead of vhdx and see if that makes any difference.
  • Wake Computer For Backup
    Thanks David for the response. I've been fiddling with this and am able to schedule the backups in Windows Task Scheduler using the CBB command line interface. It will be easier to manage when it is integrated into CBB, but this works fine for now.
  • Wake Computer For Backup
    I've just experienced the same problem - my PC failed to wake for a 1am backup. Like others before me, mine is sleeping, not hibernated. Is this something that should now be working, or is it still in development? I'm on the current version of CBB for Windows.
  • File based or image based
    Is there a technical reason why restoring individual files or folders in an image backup can't default to their original location? My retention needs generally apply at the volume level, so image backups would be a great solution IF I could more easily restore groups of individual files and/or folders.
  • Retention Plan and Backblaze
    David, I may have to back off my earlier criticism regarding documentation - I've found some pretty useful information about the CBB repository today. That said, I do have these additional questions I hope you can help with. I appreciate your assistance.
    1. Before I even knew there was a repository I was doing a lot of testing. I would create and run a backup plan, do a restore, and delete the backup data using Windows explorer, and delete the test backup plans. I have now executed the "shrink database" but I assume there are a lot of leftovers in the repository. Is there a way to reset it before I start from anew with my real backup plans?

    2. Recall I am backing up my PC to my Synology NAS and to Backblaze B2. As insurance against ransomware I would like to perform regular BTRFS Snapshots of my NAS backup folder. Then, if my CBB backup on the NAS becomes encrypted, I would roll back to a snapshot prior to the infection so I could restore my PC from the NAS. But then the backup would be out of sync with the CBB repository. Am I correct that I would need to Sync the repository before restoring to the PC? I've read some older posts where users had problems with large syncs failing. Hopefully that is a problem that has been resolved. Any best practice recommendations for the scenario I describe?

    3. Assume I have 2TB backed up on Backblaze B2 and in the future decide to move to a different cloud service. What is the most efficient way to delete all of B2 backup information from the repository? I hope it is as easy as deleting the backup plan in CBB and shrinking the repository.

    4. Can I safely convert a local files backup plan to a hybrid plan?

    5. Can I safely change encryption or compression settings in a backup plan after it has been run?
  • Retention Plan and Backblaze
    Thanks David. Just to be sure I fully understand, please confirm the following is correct:

    After an initial full hybrid backup of my data volume to my Synology NAS and my B2 S3 bucket, I will do daily hybrid backup of changed files. All versioning/retention will be managed by CBB. If I lose the original PC data volume AND the NAS backup I can copy the Backblaze restore disk drive contents to the NAS, and then reconnect CBB to the NAS and do a point-in-time restore from the NAS to the PC data volume.

    If, on the other hand, a single folder of a few GB data is corrupted on the PC and NAS, I would just use CBB to restore the folder from B2 to the PC and the next CBB hybrid backup would put everything back in sync.
  • Retention Plan and Backblaze
    David, I have followup questions regarding CBB versioning vs B2 bucket versioning. I want to feel comfortable about my ability to recover a 2+ TB data backup from B2 should I experience a ransomware attack and need to do a full restore from a point in time before the attack.

    My concern: if CBB is doing the versioning does this eliminate the ability for Backblaze to prepare a point-in-time snapshot of my backup, which they can then send to me on a hard disk. If I am still able to use Backblaze's snapshot on a hard disk, am I able to use CBB to do the restore?

    If I'm wide of the mark here, what is the recommended best practice with CBB for protection against ransomware?

    Thanks for your help.
  • Retention Plan and Backblaze
    David, what is meant by "We don't create (or support) multiple file versions on B2"? Example, if I have a file on my PC that is changed prior to every new backup (file or image) will my B2 backup contain all versions of this file (in accordance, of course, with the retention policy I have set in CBB)?

    This also brings to mind another question: Can the same B2 bucket support both file and image backups at the same time, or should I create a separate bucket for each type?

    Also fyi, my current backups on B2 S3 are tiny and strictly for testing - there is no value to me in keeping them.

    Again, thanks for your help as I navigate these new waters.
  • Retention Plan and Backblaze
    David, thanks for your response. I want to adhere to your recommendation regarding no B2 retention. Am I correct in my understanding that this will reset everything following my testing:
    1) empty my B2 S3 bucket
    2) disable B2 S3 retention
    3) invoke CBB Synchronize Repository
  • Synthetic Full Backup and Documentation
    I sure had a brain lapse on this. I was using a local disk for storage target thinking it would be an easier way to test and learn about synthetic backups and restores. Duh. I do have a B2 S3 bucket that I will be using for my real backups so I will give that a go. Thanks for your help (and patience).
