Backup Repository in Backblaze B2 Cloud Storage

To create a Backup Repository in Backblaze B2 storage, proceed as described in the following sections:


  • Forever incremental backups are not supported by this location.

Create Backup Repository: Type

On the Type page of the Create Backup Repository wizard, select Cloud and click Next to go to the next page of the wizard.

Create Backup Repository: Vendor

On the Vendor page of the wizard, select Backblaze. Click Next to proceed to the next step.

Create Backup Repository: Name & Location

On the Name & Location page of the wizard, do the following:

  1. Enter the name of the yBackup Repositor in the Name box.

  2. Select the Transporter from the Assigned transporter drop-down list.

  3. Select a Backblaze account from the Account drop-down list.

  4. In the Bucket drop-down list, select the bucket within the chosen storage account where you want to store backups.

  5. Click Next to go to the next page of the wizard.

Create Backup Repository: Options

On the Options page, do the following:

  1. In the Storage Savings section, select a compression level for reducing the data size in the Backup Repository. Note that higher compression levels consume considerably more CPU and may slow down the backup process. The following options are available:

    • Disabled: No compression.

    • Fast: Lowest compression level.

    • Medium: Medium compression level.

    • Best: Maximum compression level.

      This option cannot be configured after you create the Backup Repository.

  2. Set up Reliability & Maintenance options:

    • Run full data verification on schedule: When this option is selected, the product runs full verification of all data available in the Backup Repository based on the specified schedule. The product reads each block of data and ensures that it is identical to the data block that was read on the source machine during the backup. This way, the product verifies each recovery point in the Backup Repository.

      When Stop backup and recovery to run full data verification is selected, any running jobs that use this Backup Repository are stopped to run scheduled data verification. When this option is not selected, scheduled data verification is skipped if there are running jobs on this Backup Repository.

      Backup verification is a time-consuming process and utilizes the CPU resources of the Transporter assigned to the Backup Repository. It is recommended that you schedule backup verification during non-working hours.

    • Enforce explicit file system sync: When this option is selected, explicit sync with the file system is enforced during all backup operations to this repository. This setting is considered more reliable but may lead to lower performance on certain storage devices. This option is disabled by default.

  3. Schedule detaching of the Backup Repository:

    • Detach this repository on schedule: Select this option if you want to detach and then attach the Backup Repository based on a schedule. Detaching a Backup Repository saves the Backup Repository data and metadata in a consistent state and then stops the interaction of the product with the Backup Repository (so that the Backup Repository can be copied or moved).

    • Delete and re-create the repository on attach: When this option is selected, all the data in the Backup Repository is erased prior to attaching it to the product. As a result, jobs that write to this Backup Repository create full backups. You can use this option, for example, to create full daily, weekly, or monthly VM backups and write them to tape or removable media.

  4. Click Finish to complete Backup Repository creation.
